    A randomized phase III trial on maintenance treatment with bevacizumab alone or in combination with erlotinib after chemotherapy and bevacizumab in metastatic colorectal cancer: the Nordic ACT Trial2013Inngår i: Annals of Oncology, ISSN 0923-7534, E-ISSN 1569-8041, Vol. 24, nr 9, s. 2335-2341Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The main objective was to study the effect on progression-free survival (PFS) of adding erlotinib to bevacizumab as maintenance treatment following chemotherapy and bevacizumab as first-line treatment of metastatic colorectal cancer (mCRC). Patients and methods: Patients with untreated mCRC received doublet chemotherapy + bevacizumab during 18 weeks and those without tumor progression were eligible for randomization to bevacizumab + erlotinib (arm A) or bevacizumab alone (arm B), until progression or unacceptable toxic effect. Results: Of the 249 patients enrolled, 80 started maintenance treatment in arm A and 79 in arm B. The rate of any grade 3/4 toxic effect was 53% in arm A and 13% in arm B. Median PFS was 5.7 months in arm A and 4.2 months in arm B (HR = 0.79; 95% confidence interval 0.55-1.12; P = 0.19). Overall survival (OS) from start of induction chemotherapy was 26.7 months in the randomized population, with no difference between the two arms. Conclusions: The addition of erlotinib to bevacizumab as maintenance treatment after first-line chemotherapy in mCRC did not improve PFS significantly. On-going clinical and translational studies focus on identifying subgroups of patients that may benefit from erlotinib in the maintenance setting.

    Cancer incidence and mortality patterns in women with anorexia nervosa2014Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 134, nr 7, s. 1751-1757Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Caloric restriction in animals is an effective way to reduce carcinogenesis. Anorexia nervosa (AN) is considered a model of extreme caloric restriction in humans. The aim of our study was to assess cancer incidence and mortality in women with AN. A total of 6,009 women with at least one inpatient treatment for AN during the period 1973-2003 were included in the study. Standardized incidence ratios (SIR) and standardized mortality ratios (SMR) were calculated. Overall, there was no statistically significant difference in cancer incidence compared to women in the general population. At a statistically significant or borderline significant level, a higher incidence for lung cancer and cancer of lymphoid, hematopoietic and related tissue was observed along with a reduced breast cancer incidence. Women with AN had twice as high mortality from cancer in general, and more specifically from melanoma, cancers of genital organs and cancers of ill-defined, secondary and unspecified sites. The increased lung cancer incidence may be due to smoking habits among women with AN. The worse prognosis with higher mortality from melanoma, cancers of genital organs and cancers of ill-defined, secondary and unspecified sites may be explained by AN-specific attitudes toward seeking medical care, adherence to treatment or worse biological precondition due to starvation and cachexia.

    Loss of cancer drug activity in colon cancer HCT-116 cells during spheroid formation in a new 3-D spheroid cell culture system2012Inngår i: Experimental Cell Research, ISSN 0014-4827, E-ISSN 1090-2422, Vol. 318, nr 13, s. 1577-1585Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Clinically relevant in vitro methods are needed to identify new cancer drugs for solid tumors. We report on a new 3-D spheroid cell culture system aimed to mimic the properties of solid tumors in vivo. The colon cancer cell lines HCT-116 wt and HCT-116 wt/GFP were grown as monolayers and for 3 or 6 days on 96-well NanoCulture (R) plates to form spheroids. Expression of surface markers, genes and hypoxia were assessed to characterize the spheroids and drug induced cytotoxicity was evaluated based on fluorescein diacetate (FDA) conversion by viable cells to fluorescent fluorescein or by direct measurement of fluorescence of GFP marked cells after a 72 h drug incubation. The cells reproducibly formed spheroids in the NanoCulture (R) plates with tight cell-attachment after 6 days. Cells in spheroids showed geno- and phenotypical properties reminiscent of hypoxic stem cells. Monolayer cultured cells were sensitive to standard and investigational drugs, whereas the spheroids gradually turned resistant. Similar results for cytotoxicity were observed using simplified direct measurement of fluorescence of GFP marked cells compared with FDA incubation. In conclusion, this new 3-D spheroid cell culture system provides a convenient and clinically relevant model for the identification and characterization of cancer drugs for solid tumors.

    Lymphoedema and health-related quality of life by early treatment in long-term survivors of breast cancer. A comparative retrospective study up to 15 years after diagnosis2015Inngår i: Supportive Care in Cancer, ISSN 0941-4355, E-ISSN 1433-7339, Vol. 23, nr 10, s. 2965-2972Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose The purpose was to compare progression/regression of arm lymphoedema, health-related quality of life and medical background data among women who discontinued their treatment (non-continued treatment group, NCTG) with these factors among women who continued treatment (continued treatment group, CTG).

    Methods Seventy-two women were included in the NCTG and 58 women in the CTG. Women in the NCTG were invited to an examination and measurement of affected arm volume at the clinic in 2008. Medical background data and arm volume values, measured using the water displacement method, were collected from patient records and the Breast Cancer Quality Register of the Uppsala Örebro Region. The functional assessment of cancer therapy for breast cancer (FACT-B) was used to assess health-related quality of life in both groups.

    Results There were no differences with regard to progression/regression of arm lymphoedema or health-related quality of life. The CTG had experienced more advanced disease and received more extensive surgical and oncological treatment. The CTG had significantly larger arm volume due to lymphoedema at diagnosis (mean 422 ml) compared to the NCTG (mean 283 ml; p < 0.001), and at the last visit at the clinic (CTG mean 414 ml versus NCTG mean 239 ml; p < 0.001).

    Conclusions The results indicate that there might be a spontaneous regression of lymphoedemas in the NCTG but there is a need for more research to make it possible to draw firm conclusions regarding this.

    A Pragmatic Definition of Therapeutic Synergy Suitable for Clinically Relevant In Vitro Multicompound Analyses2014Inngår i: Molecular Cancer Therapeutics, ISSN 1535-7163, E-ISSN 1538-8514, Vol. 13, nr 7, s. 1964-1976Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    For decades, the standard procedure when screening for candidate anticancer drug combinations has been to search for synergy, defined as any positive deviation from trivial cases like when the drugs are regarded as diluted versions of each other (Loewe additivity), independent actions (Bliss independence), or no interaction terms in a response surface model (no interaction). Here, we show that this kind of conventional synergy analysis may be completely misleading when the goal is to detect if there is a promising in vitro therapeutic window. Motivated by this result, and the fact that a drug combination offering a promising therapeutic window seldom is interesting if one of its constituent drugs can provide the same window alone, the largely overlooked concept of therapeutic synergy (TS) is reintroduced. In vitro TS is said to occur when the largest therapeutic window obtained by the best drug combination cannot be achieved by any single drug within the concentration range studied. Using this definition of TS, we introduce a procedure that enables its use in modern massively parallel experiments supported by a statistical omnibus test for TS designed to avoid the multiple testing problem. Finally, we suggest how one may perform TS analysis, via computational predictions of the reference cell responses, when only the target cell responses are available. In conclusion, the conventional error-prone search for promising drug combinations may be improved by replacing conventional (toxicology-rooted) synergy analysis with an analysis focused on (clinically motivated) TS.

    Trabectedin plus pegylated liposomal doxorubicin in relapsed ovarian cancer delays third-line chemotherapy and prolongs the platinum-free interval2011Inngår i: Annals of Oncology, ISSN 0923-7534, E-ISSN 1569-8041, Vol. 22, nr 1, s. 49-58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: OVA-301 is a large randomized trial that showed superiority of trabectedin plus pegylated liposomal doxorubicin (PLD; CentoCor Ortho Biotech Products L. P., Raritan, NJ, USA). over single-agent PLD in 672 patients with relapsed ovarian cancer, particularly in the partially platinum-sensitive subgroup [platinum-free interval (PFI) of 6-12 months]. This superiority has been suggested to be due to the differential impact of subsequent (platinum) therapy. Patients and methods: A detailed analysis of subsequent therapies and survival outcomes in the overall population and in the subsets according to platinum sensitivity was therefore conducted. Results: Similar proportions of patients received subsequent therapy in each arm (76% versus 77%), including further platinum-based regimens (49% versus 55%). Patients in the trabectedin/PLD arm received subsequent chemotherapy at a later time (median delay 2.5 months versus PLD arm). Overall survival from subsequent platinum was significantly prolonged in the partially platinum-sensitive disease subset (hazard ratio = 0.63; P = 0.0357). Conclusion: The superiority of trabectedin/PLD over single-agent PLD in OVA-301 cannot be explained by differences in the extent or nature of subsequent therapies administered to these patients. On the other hand, these exploratory analyses support the hypothesis that the enhanced survival benefits in the partially platinum-sensitive subset might be due to an extended PFI leading to longer survival with subsequent platinum.

    Toxicity in patients receiving adjuvant docetaxel plus hormonal treatment after radical radiotherapy for intermediate or high-risk prostate cancer: a preplanned safety report of the SPCG-13 trial2012Inngår i: Prostate Cancer and Prostatic Diseases, ISSN 1365-7852, E-ISSN 1476-5608, Vol. 15, nr 3, s. 303-307Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Radical radiotherapy (RD combined with androgen deprivation therapy is currently the standard treatment for elderly patients with localized intermediate- or high-risk prostate cancer (PC). To increase the recurrence-free and overall survival, we conducted an adjuvant, randomized trial using docetaxel (T) in PC patients (Scandinavian Prostate Cancer Group trial 13). METHODS: The inclusion criteria are the following: men > 18 and <= 75 years of age, WHO/ECOG performance status 0-1, histologically proven PC within 12 months before randomization and one of the following: T2, Gleason 7 (4 + 3), PSA > 10; T2, Gleason 8-10, any PSA; or any T3 tumors. Neoadjuvant/adjuvant hormone therapy is mandatory for all patients. The patients were randomized to receive six cycles of T (75 mg m(-2) d 1. cycle 21 d) or no docetaxel after radical RI (with a minimum tumor dose of 74 Gy). This study identifier number is NTC 006653848 (http://www.clinicaltrials.org). RESULTS: In this preplanned safety analysis of 100 patients, T treatment induced grade (G) 3 adverse events (AEs) in 15 patients (30%) and G4 AEs in 30 patients (60%), mainly due to bone marrow toxicity. Neutropenia G3-4 was observed in 72% of the patients, febrile neutropenia was found in 24% of patients, neutropenic infection in 10% of patients and G3 infection without neutropenia in 4% of patients. Nonhematological G3 AEs were rare: anorexia, diarrhea, mucositis, nausea, pain (1 patient each) and fatigue (5). Other severe serious AEs related to T were pulmonary embolism and renal failure. However, only three patients discontinued T before completing the planned six cycles. No deaths had occurred. No patients in the control arm experienced G3-4 toxicities at 12 weeks after the randomization. CONCLUSIONS: Adjuvant docetaxel chemotherapy after radiotherapy has a higher frequency of neutropenia than previous studies on patients with metastatic disease. Otherwise, the treatment was quite well tolerated.

    A population-based study of 135 lymphomas after solid organ transplantation: The role of Epstein-Barr virus, hepatitis C and diffuse large B-cell lymphoma subtype in clinical presentation and survival.2014Inngår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 53, nr 5, s. 669-679Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background. Epstein-Barr virus (EBV) plays a major role in the development of post-transplant lymphoproliferative disorder (PTLD), but there is an increasing awareness of EBV-negative PTLD. The clinical presentation of EBV-negative PTLD has not been as well characterised as EBV-positive cases. Further, there is limited knowledge on the clinical importance of diffuse large B-cell lymphoma (DLBCL) cell of origin subtype post-transplant. Materials and methods. We studied the role of EBV, hepatitis C (HCV) and DLBCL subtype in clinical presentation and survival in 135 post-transplant lymphomas diagnosed 1980-2006 in a population-based cohort of 10 010 Swedish solid organ transplant recipients. The lymphomas were re-evaluated according to WHO 2008, examined for EBV, and clinical data were collected from medical records. Results. Lymphoma incidence rate was 159/100 000 person-years and is also reported by lymphoma subtype. EBV-negative lymphomas constituted 48% and were associated with HCV infection (p = 0.02), bone marrow involvement (p < 0.001), and T-cell phenotype (p = 0.002). Among DLBCL, 78% were of non-germinal centre subtype, which was associated with EBV-positivity (69%, p = 0.001), early occurrence (p = 0.03), heart/liver/lung/pancreas recipients (p = 0.02), anti-T-cell globulin (p = 0.001), and tacrolimus treatment (p = 0.02). DLBCL subtypes had similar overall survival. Five-year overall survival was 42% in all treated patients. Independent poor prognostic factors were older age, B symptoms, ECOG 2-4, kidney/pancreas/heart recipients, T-cell lymphoma, and HCV-infection. Conclusions. With long follow-up, a large part of PTLD is EBV-negative, due to a high proportion of T-cell lymphomas and low of polymorphic PTLD. EBV-negative PTLD have a different clinical presentation. HCV may play an aetiological role in late-onset PTLD and was revealed as a new prognostic factor for inferior survival that needs to be confirmed in larger studies. The heavier immunosuppression in non-kidney transplantations seems to play a role in the development of non-germinal centre DLBCL. DLBCL cell of origin subtype lacks prognostic importance in the transplant setting.

    Donor or Recipient Origin of Posttransplant Lymphoproliferative Disorders Following Solid Organ Transplantation2014Inngår i: American Journal of Transplantation, ISSN 1600-6135, E-ISSN 1600-6143, Vol. 14, nr 12, s. 2838-2845Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Previous studies of donor or recipient origin of posttransplant lymphoproliferative disorders (PTLDs) following solid organ transplantation (SOT) have either been small or with selected patient groups. We studied tumor origin in a population-based cohort of 93 patients with PTLD following SOT. Tumor origin of PTLD tissue was analyzed by fluorescence in situ hybridization of the sex chromosomes in cases of sex mismatch between donor and recipient (n=41), or HLA genotyping in cases of identical sex but different HLA type (n=52). Tumor origin of PTLD could be determined in 67 of the 93 cases. All 67 PTLDs were of recipient origin. They were found in recipients of kidney (n=38), liver (n=12), heart (n=10) and lung (n=7). The most common recipient-derived lymphomas were monomorphic B-cell PTLDs (n=45), monomorphic T cell PTLDs (n=9), indolent lymphomas (n=6), and polymorphic PTLD (n=4). Half of the recipient-derived PTLDs were Epstein–Barr virus-positive. Twelve of the recipient-derived PTLDs were located in the grafts: in four cases exclusively and in eight cases in combination with disseminated disease outside the graft. Tumor origin was indeterminable in 26 cases, probably due to low DNA quality. We conclude that the vast majority of PTLDs after SOT was of recipient origin.

    Let-7 miRNA-binding site polymorphism in the KRAS 3`UTR; colorectal cancer screening population prevalence and influence on clinical outcome in patients with metastatic colorectal cancer treated with 5-fluorouracil and oxaliplatin +/- cetuximab.2012Inngår i: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 12, nr 1, s. 534-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Recent studies have reported associations between a variant allele in a let-7 microRNA complementary site (LCS6) within the 3 untranslated region (3 UTR) of KRAS (rs61764370) and clinical outcome in metastatic colorectal cancer (mCRC) patients receiving cetuximab. The variant allele has also been associated with increased cancer risk. We aimed to reveal the incidence of the variant allele in a colorectal cancer screening population and to investigate the clinical relevance of the variant allele in mCRC patients treated with 1st line 5-fluorouracil-oxaliplatin (Nordic FLOX) +/- cetuximab.

    METHODS: The feasibility of the variant allele as a risk factor for CRC was investigated by comparing the LCS6 gene frequencies in 197 CRC patients, 1060 individuals with colorectal polyps, and 358 healthy controls. The relationship between clinical outcome and LCS6 genotype was analyzed in 180 mCRC patients receiving Nordic FLOX and 355 patients receiving Nordic FLOX + cetuximab in the NORDIC-VII trial (NCT00145314). RESULTS: LCS6 frequencies did not vary between CRC patients (23%), individuals with polyps (20%), and healthy controls (20%) (P=0.50). No statistically significant differences were demonstrated in the NORDIC-VII cohort even if numerically increased progression-free survival (PFS) and overall survival (OS) were found in patients with the LCS6 variant allele (8.5 (95% CI: 7.3-9.7 months) versus 7.8 months (95% CI: 7.4-8.3 months), P=0.16 and 23.5 (95% CI: 21.6-25.4 months) versus 19.5 months (95% CI: 17.8-21.2 months), P=0.31, respectively). Addition of cetuximab seemed to improve response rate more in variant carriers than in wild-type carriers (from 35% to 57% versus 44% to 47%), however the difference was not statistically significant (interaction P = 0.16).

    CONCLUSIONS: The LCS6 variant allele does not seem to be a risk factor for development of colorectal polyps or CRC. No statistically significant effect of the LCS6 variant allele on response rate, PFS or OS was found in mCRC patients treated with 1st line 5-fluorouracil-oxaliplatin +/- cetuximab.

    The Prognostic Value of Mitotic Activity Index (MAI), Phosphohistone H3 (PPH3), Cyclin B1, Cyclin A, and Ki67, Alone and in Combinations, in Node-Negative Premenopausal Breast Cancer2013Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, nr 12Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Proliferation, either as the main common denominator in genetic profiles, or in the form of single factors such as Ki67, is recommended for clinical use especially in estrogen receptor-positive (ER) patients. However, due to high costs of genetic profiles and lack of reproducibility for Ki67, studies on other proliferation factors are warranted. The aim of the present study was to evaluate the prognostic value of the proliferation factors mitotic activity index (MAI), phosphohistone H3 (PPH3), cyclin B1, cyclin A and Ki67, alone and in combinations. In 222 consecutive premenopausal node-negative breast cancer patients (87% without adjuvant medical treatment), MAI was assessed on whole tissue sections (predefined cut-off >= 10 mitoses), and PPH3, cyclin B1, cyclin A, and Ki67 on tissue microarray (predefined cut-offs 7th decile). In univariable analysis (high versus low) the strongest prognostic proliferation factor for 10-year distant disease-free survival was MAI (Hazard Ratio (HR)=3.3, 95% Confidence Interval (CI): 1.8-6.1), followed by PPH3, cyclin A, Ki67, and cyclin B1. A combination variable, with patients with MAI and/or cyclin A high defined as high-risk, had even stronger prognostic value (HR=4.2, 95% CI: 2.2-7). When stratifying for ER-status, MAI was a significant prognostic factor in ER-positive patients only (HR=7.0, 95% CI: 3.1-16). Stratified for histological grade, MAI added prognostic value in grade 2 (HR=7.2, 95% CI: 3.1-38) and grade 1 patients. In multivariable analysis including HER2, age, adjuvant medical treatment, ER, and one proliferation factor at a time, only MAI (HR=2.7, 95% CI: 1.1-6.7), and cyclin A (HR=2.7, 95% CI: 1.2-6.0) remained independently prognostic. In conclusion this study confirms the strong prognostic value of all proliferation factors, especially MAI and cyclin A, in all patients, and more specifically in ER-positive patients, and patients with histological grade 2 and 1. Additionally, by combining two proliferation factors, an even stronger prognostic value may be found.

    Population-based data from the Swedish Colon Cancer Registry2013Inngår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 100, nr 8, s. 1100-1107Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background Evaluating the external validity of clinical trials requires knowledge not only of the study population but also of a relevant reference population. The main aim of this study was to present data from a large, contemporary, population-based cohort of patients with colonic cancer. Methods Data on patients diagnosed between 2007 and 2011 were extracted from the Swedish Colon Cancer Registry. The data, registered prospectively in a national population of almost 10 million, included over 99 per cent of all diagnosed adenocarcinomas of the colon. Results This analysis included 18889 patients with 19526 tumours (3 center dot 0 per cent had synchronous tumours). The sex distribution was fairly equal, and the median age was 74 center dot 1 (interquartile range 65-81) years. The overall and relative (cancer-specific) survival rates after 3 years were 62 center dot 7 and 71 center dot 4 per cent respectively. Some 88 center dot 0 per cent of the patients were operated on, and 83 center dot 8 per cent had tumours resected. Median blood loss during bowel resection was 200 (mean 311) ml, and the median operating time was 160min; 5 center dot 6 per cent of the procedures were laparoscopic. Preoperative chemotherapy was administered to 2 center dot 1 per cent of patients; postoperative chemotherapy was planned in 90 center dot 1 per cent of fit patients aged less than 75 years with stage III disease. In patients operated on in an emergency setting (21 center dot 5 per cent), the preoperative evaluation was less extensive, the proportion of R0 resections was lower, and the outcomes were poorer, in both the short and long term. Conclusion These population-based data represent good-quality reference points.

    Cyclin A is an excellent proliferation marker for identifying luminal breast cancer subgroups using immunohistochemistryManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Background. Gene arrays have demonstrated different outcomes for breast cancer subtypes highlighting the heterogeneity of breast cancer. The limited availability of gene expression analysis and financial issues have  contributed to the development of surrogate markers to identify corresponding subgroups using IHC. 2011 ESMO and St Gallen guidelines suggest the use of an IHC panel consisting of ER, PgR, HER2 and Ki67 cut-off value ≥14 % (Ki6714%) for discriminating luminal A from B.The cut-off value suggested from 2013 St Gallens guidelines was ≥20% (Ki6720%). We wanted to evaluate if the different cut-off values for Ki67 or cyclins A/B1  could reliably separate luminal A from B.

     

    Patients. In a case-control study, we defined 190 women who died from breast cancer as cases and 190 women alive at the time for the corresponding case's death as controls. Inclusion criteria were tumor size ≤50 mm, no lymph node metastases and no adjuvant chemotherapy. Immunohistochemical evaluation of ER, PgR, HER2, Ki 67, cyclin A and cyclin B1 were utilized for subgrouping.

     

    Results. Conditional logistic regression analysis was used to estimate odds ratios (OR) for breast cancer death. Ki6714% did not detect differences in outcome between luminal A and B breast cancer (OR 1.4, 95% CI 0.8-2.26 p-value 0.24). Corresponding values for  cyclin A was OR 3.6 (95% CI 1.8-7.0 p-value 0.00), cyclin B1  2.2 (95% CI 1.1-4.5  p-value 0.04) and Ki6720% 2.0 (95% CI 1.1-3.9 p-value 0.04) using  luminal A as reference.

    Conclusion.   In our study, Ki6714% failed to detect any difference in outcome between luminal A and B. In contrast, using cyclin A as a proliferation marker luminal B was found to have an almost 3.5 -fold higher risk of dying from breast cancer. Cyclin B1 and Ki6720%, could also separate luminal A from B but cyclin A  separated more effectively these subtypes . We conclude that cyclin A distinctly  separates luminal A from B in node negative breast cancer.

    PPH3 is an independent prognostic factor in node negative breast cancer, however outperformed by cyclin A in the ER positive patients.Manuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Background. Proliferation conveys prognostic information and directs treatment choices in early and especially in estrogen receptor (ER) positive breast cancer. Ki67 is the proliferation marker, which is recommended by the 2013 St Gallen International Breast Cancer Conference to distinguish Luminal A-like from Luminal B-like breast cancer. However, the lack of standardization and absence of a clearly established cut-off value are limitations for the clinical use of Ki67. Recent studies in node negative breast cancer suggest that phosphorylated histone 3 (PPH3) may predict breast cancer death. Our aim was to examine the prognostic role of PPH3 compared to the proliferation markers Ki67, cyclin A and cyclin B1 in node negative breast cancer with a special focus on ER positive disease.

    Patients and methods. In a case-control study, we defined 190 women who died from node negative breast cancer as cases and 190 women who were alive at the time for the corresponding case's death as controls. Inclusion criteria were tumor size ≤50 mm, no lymph node metastases and no adjuvant chemotherapy. Of these 380 subjects, 249 had ER positive disease. Tumor tissues were immunostained for PPH3 using commercially available antibodies. The actual number of immunostained cells in 10 fields of view (PPH3 index) and the percentage of immunostained cells counting 200 and 500 tumor cells were calculated.

    Results. In node negative patients, PPH3 indexrevealed an odds ratio (OR) for breast cancer death of 2.6 (95% confidence interval (CI) 1.6-4.5 p-value <0.001). PPH3 was strongly correlated to Ki67, histological grade, mitotic count and cyclin A and B1. In ER positive patients the OR for PPH3 index was 2.9 (95% CI 1.6-5.2 p-value <0.001) while the OR for Cyclin A was 3.8 (95% CI 2.2-6.6 p-value <0.001), for cyclin B1 2.9 (95%CI 1.7-4.9 p-value <0.001) and for Ki67 1.6 (95% CI 0.9-4.9 p-value 0,09). However, multivariate analyses showed that cyclin A was the only independent prognostic marker for breast cancer death in ER positive patients, OR 3.6 (95% CI 1.6-8.1 p-value 0.002).

    Conclusion. In this study of node negative breast cancer patients, PPH3 showed to be a prognostic factor for breast cancer death. In ER positive patients PPH3 and cyclin A/B1 but not Ki67 could predict breast cancer death. However in the multivariate analysis of proliferation markers, only cyclin A remains as a prognostic factor.

    The Prognostic Impact of Proliferation Markers in Breast Cancer with Emphasis on Cyclin B1 and PPH32014Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis was to investigate the prognostic role of the proliferation markers cyclin B1 and Phosphorylated Histone 3 (PPH3) in breast cancer (BC).

    In paper I we used an experimental study design, we compared women dying early from their BC with women free from relapse more than eight years after initial diagnosis. All women had stage I, node-negative and hormone receptor positive disease. None had received adjuvant chemotherapy. We found that low-risk node negative patients with high expression of cyclin B1 had a significantly worse outcome than patients with low expression of cyclin B1.

    In paper II a population-based case control study was performed to further investigate the prognostic value of cyclin B1. One hundred and ninety women who died from BC were defined as cases and 190 women alive at the time for the corresponding case’s death were defined as controls. Inclusion criteria were tumor size 50 mm, no lymph node metastases, and no adjuvant chemotherapy. Two investigators evaluated the stainings independently. Cyclin B1 was found to be a prognostic factor for BC death that could identify high-risk patients with a good to very good reproducibility.

    Paper III aimed to investigate the role of proliferation in male breast cancer (MBC). One hundred and ninety-seven MBC tumors were stained for cyclin A, B1, D1 and Ki67. Overexpression of cyclin A and B1 and elevated mitotic count were predictive of breast cancer death. Ki67 was re-evaluated and different cut-offs were used, but no prognostic value could be demonstrated. On the other hand high levels of cyclin D1 were associated with better outcome in MBC.

    In paper IV we applied the immunohistochemichal panel suggested from international guidelines to the same patient material as in paper II, to discriminate luminal A from luminal B BC. We wanted to evaluate if different cut-off values of Ki67, cyclin A or B1 could more clearly separate luminal A from B. Cyclin A, B1 and Ki67 (cut-off 20%) could detect difference in outcome between these subtypes with cyclin A showing greater prognostic value.

    The aim of paper V was to examine the prognostic role of PPH3 compared to the proliferation markers Ki67, cyclin A and cyclin B1 with focus on ER positive disease. PPH3 was found to be a prognostic factor for breast cancer death but in the multivariate analysis including all proliferation markers, only cyclin A remained a prognostic factor.

    Finally, we conclude that both cyclin B1 and PPH3 are prognostic factors for breast cancer death, but are outperformed by cyclin A in ER positive patients. In male breast cancer prognostic factors need to be further studied.

    Abstract [en]

    Patients with low-risk node negative breast cancer have an excellent prognosis with 5% breast cancer mortality at 10 years. However, prognostic factors are needed to identify poor prognostic patients who might benefit from adjuvant systemic therapy. Proliferation has been identified as the most important component of gene expression profiles. Cyclin B is a proliferative marker easily assessed by immunohistochemistry. We wanted to examine cyclin B as a prognostic factor in low-risk breast cancer patients. Patients and methods. Using an experimental study design, we compared women dying early from their breast cancer (n=17) with women free from relapse more than eight years after initial diagnosis (n=24). All women had stage I, node negative and hormone receptor positive disease. None had received adjuvant chemotherapy. Tumor samples were immunostained for cyclin B using commercial antibodies. Results. The mean percentage of cyclin B (12%) was significantly higher (p=0.001) in women dying from their breast cancer compared with women free from relapse ( 5%). High cyclin B (>= 9%) identified 11/17 patients dying from breast cancer and low cyclin B identified 22/24 patients free from relapse. The sensitivity and specificity of cyclin B was 65% and 92%, respectively. Discussion. We found that low-risk node negative patients with high expression of cylin B had a significantly worse outcome than patients with low expression of cyclin B. Cyclin B could separate patients with poor survival from those with good survival with 80% accuracy. We suggest that cyclin B might be a potent prognostic factor in this low-risk patient group.

    Abstract [en]

    Assessment of proliferation is important in female breast cancer and individual treatment decisions are based upon its results, especially in the lumina! subgroups. Gene expression analyses fail to group male breast cancer into the intrinsic subgroups previously established in female breast cancer. Even though proliferation has been shown to divide malebreast cancer into molecular subgroups with different prognoses, the clinical importance ofproliferation markers has not yet been elucidated. Previous studies in male breast cancer have demonstrated contradictory results regarding the prognostic impact of histological grade and Ki-67, parameters strongly associated with proliferation. The aim of the present project was to studyproliferation in male breast cancer by assessing other proliferation-related markers viz. cyclins A, B, D1 and mitotic count. A total of 197 male breast cancer cases with accessible paraffin-embedded material and outcome data were investigated. Immunohistochemical stainings were performed on tissue microarrays. Kaplan-Meier estimates and the Cox proportional regression models were used for survival analyses with breast cancer death as the event. The subset ofpatients with high expression of cyclin A (hazard ratio (HR) 3.7; P=0.001) and B (HR 2.7; P=0.02) demonstrated a poorer survival. Furthermore, high mitotic count was associated with an increased risk of breast cancer death (HR 2.5; P=0.01). In contrast, cyclin D1 overexpression was predictive of better breast cancer survival (HR 0.3; P=0.001). In conclusion, high levels of cyclin A and B expression and an elevated mitotic count result in a two to threefold higher risk forbreast cancer death, whereas cyclin D1 overexpression halves the risk. The clinical utility of these proliferation markers needs further elucidation.

In ER positive patients PPH3 and cyclin A/B1 but not Ki67 could predict breast cancer death. However in the multivariate analysis of proliferation markers, only cyclin A remains as a prognostic factor.

    Cyclin B is an immunohistochemical proliferation marker which can predict for breast cancer death in low-risk node negative breast cancer2010Inngår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 49, nr 6, s. 816-820Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Patients with low-risk node negative breast cancer have an excellent prognosis with 5% breast cancer mortality at 10 years. However, prognostic factors are needed to identify poor prognostic patients who might benefit from adjuvant systemic therapy. Proliferation has been identified as the most important component of gene expression profiles. Cyclin B is a proliferative marker easily assessed by immunohistochemistry. We wanted to examine cyclin B as a prognostic factor in low-risk breast cancer patients. Patients and methods. Using an experimental study design, we compared women dying early from their breast cancer (n=17) with women free from relapse more than eight years after initial diagnosis (n=24). All women had stage I, node negative and hormone receptor positive disease. None had received adjuvant chemotherapy. Tumor samples were immunostained for cyclin B using commercial antibodies. Results. The mean percentage of cyclin B (12%) was significantly higher (p=0.001) in women dying from their breast cancer compared with women free from relapse ( 5%). High cyclin B (>= 9%) identified 11/17 patients dying from breast cancer and low cyclin B identified 22/24 patients free from relapse. The sensitivity and specificity of cyclin B was 65% and 92%, respectively. Discussion. We found that low-risk node negative patients with high expression of cylin B had a significantly worse outcome than patients with low expression of cyclin B. Cyclin B could separate patients with poor survival from those with good survival with 80% accuracy. We suggest that cyclin B might be a potent prognostic factor in this low-risk patient group.

    Nordic MCL-3 study: 90Y-ibritumomab-tiuxetan added to BEAM/C in non-CR patients before transplant in mantle cell lymphoma2014Inngår i: Blood, ISSN 0006-4971, E-ISSN 1528-0020, Vol. 123, nr 19, s. 2953-2959Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The main objective of the MCL3 study was to improve outcome for patients not in CR before transplant by adding (90)Y-ibritumomab-tiuxetan (Zevalin) to the high-dose regimen. 160 consecutive, untreated stage II-IV MCL patients < 66 years received rituximab (R)- maxi-CHOP alternating with R-high-dose Ara-C (6 cycles total), followed by high-dose BEAM or BEAC and autologous stem cell transplantation 2005-2009. Zevalin (0.4 mCi/kg) was given to responders in only CRu/PR prior to high-dose therapy. The overall response rate (ORR) pre-transplant was 97%. After a median follow-up of 4.4 years the outcome did not differ from that of the historic control, the MCL2 trial with the same treatment except for Zevalin. Overall (OS), event free (EFS), and progression-free survival (PFS) at 4 years were 78, 62 and 71%, respectively. For patients in CRu/PR before transplant who received Zevalin duration of response was shorter than in the CR group. Inferior PFS, EFS- and OS were predicted by PET-positivity pre-transplant and detectable minimal residual disease (MRD) before and after transplant. In conclusion, a positive PET prior to transplant and MRD are strong predictors of outcome. Late intensification with Zevalin may be too late to improve the outcome of patients not in CR before transplant.

    An Ethyl Acetate Fraction of Moringa oleifera Lam. Inhibits Human Macrophage Cytokine Production Induced by Cigarette Smoke2014Inngår i: Nutrients, ISSN 2072-6643, E-ISSN 2072-6643, Vol. 6, nr 2, s. 697-710Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Moringa oleifera Lam. (MO) has been reported to harbor anti-oxidation and anti-inflammatory activity and useful in the treatment of inflammatory diseases. However, despite these findings there has been little work done on the effects of MO on immune cellular function. Since macrophages, TNF and related cytokines play an important pathophysiologic role in lung damage induced by cigarette smoke, we examined the effects of MO on cigarette smoke extract (CSE)-induced cytokine production by human macrophages. An ethyl acetate fraction of MO (MOEF) was prepared from fresh leaves extract of Moringa and shown to consist of high levels of phenolic and antioxidant activities. Human monocyte derived macrophages (MDM) pre-treated with varying concentrations of MOEF showed decreased production of TNF, IL-6 and IL-8 in response to both LPS and CSE. The decrease was evident at both cytokine protein and mRNA levels. Furthermore, the extract inhibited the expression of RelA, a gene implicated in the NF-kappa B p65 signaling in inflammation. The findings highlight the ability of MOEF to inhibit cytokines (IL-8) which promote the infiltration of neutrophils into the lungs and others (TNF, IL-6) which mediate tissue disease and damage.

    Assessment of volume segmentation in radiotherapy of adolescents; a treatment planning study by the Swedish Workgroup for Paediatric Radiotherapy2014Inngår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 53, nr 1, s. 126-133Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background and purpose. The variability in target delineation for similar cases between centres treating paediatric and adolescent patients, and the apparent differences in interpretation of radiotherapy guidelines in the treatment protocols encouraged us to perform a dummy-run study as a part of our quality assurance work. The aim was to identify and quantify differences in the segmentation of target volumes and organs at risk (OARs) and to analyse the treatment plans and dose distributions. Materials and methods. Four patient cases were selected: Wilm's tumour, Hodgkin's disease, rhabdomyosarcoma of the prostate and chordoma of the skull base. The five participating centres received the same patient-related material. They introduced the cases in their treatment planning system, delineated target volumes and OARs and created treatment plans. Dose-volume histograms were retrieved for relevant structures and volumes and dose metrics were derived and compared, e. g. target volumes and their concordance, dose homogeneity index (HI), treated and irradiated volumes, remaining volume at risk and relevant V x and D x values. Results. We found significant differences in target segmentation in the majority of the cases. The planning target volumes (PTVs) varied two-to four-fold and conformity indices were in the range of 0.3-0.6. This resulted in large variations in dose distributions to OARs as well as in treated and irradiated volumes even though the treatment plans showed good conformity to the PTVs. Potential reasons for the differences in target delineation were analysed. Conclusion. Considerations of the growing child and difficulties in interpretation of the radiotherapy information in the treatment protocols were identified as reasons for the variation. As a result, clarified translated detailed radiotherapy guidelines for paediatric/adolescent patients have been recognised as a way to reduce this variation.

    Amplification of 2p as a Genomic Marker for Transformation in Lymphoma2014Inngår i: Genes, Chromosomes and Cancer, ISSN 1045-2257, E-ISSN 1098-2264, Vol. 53, nr 9, s. 750-768Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To outline further genetic mechanisms of transformation from follicular lymphoma (FL) to diffuse large B-cell lymphoma (DLBCL), we have performed whole genome array-CGH in 81 tumors from 60 patients [29 de novo DLBCL (dnDLBCL), 31 transformed DLBCL (tDLBCL), and 21 antecedent FL]. In 15 patients, paired tumor samples (primary FL and a subsequent tDLBCL) were available, among which three possessed more than two subsequent tumors, allowing us to follow specific genetic alterations acquired before, during, and after the transformation. Gain of 2p15-16.1 encompassing, among others, the REL, BCL11A, USP34, COMMD1, and OTX1 genes was found to be more common in the tDLBCL compared with dnDLBCL (P < 0.001). Furthermore, a high-level amplification of 2p15-16.1 was also detected in the FL stage prior to transformation, indicating its importance during the transformation event. Quantitative real-time PCR showed a higher level of amplification of REL, USP34, and COMMD1 (all involved in the NF kappa B-pathway) compared with BCL11A, which indicates that the altered genes disrupting the NF kappa B pathway may be the driver genes of transformation rather than the previously suggested BCL11A. Moreover, a 17q21.33 amplification was exclusively found in tDLBCL, never in FL (P < 0.04) or dnDLBCL, indicating an upregulation of genes of importance during the later phase of transformation. Taken together, our study demonstrates potential genomic markers for disease progression to clinically more aggressive forms. We also confirm the importance of the TP53-, CDKN2A-, and NF kappa B-pathways for the transformation from FL to DLBCL.

    Positron emission tomography (PET) with 11C-5-hydroxytryptophan (5-HTP) in patients with metastatic hormone-refractory prostatic adenocarcinoma1997Inngår i: Nuclear Medicine and Biology, ISSN 0969-8051, E-ISSN 1872-9614, Vol. 24, nr 4, s. 319-325Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The discovery of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma has opened a potentially new therapeutic approach in this group of patients with a poor prognosis and few effective therapy modalities. Based on previous findings of increased uptake of 11C-5-hydroxytryptophan (11C-5-HTP) in neuroendocrine tumours using the PET technique, this tracer was applied in the study of 10 patients with metastatic hormone-refractory prostatic adenocarcinoma. In three patients, the study was repeated after treatment. An increased uptake of 11C-5-HTP was observed in all investigated skeletal lesions, although the magnitude of the uptake was moderate. The difference between the standard uptake values (SUV) in normal bone and metastatic lesions was significant (p < 0.001). A kinetic analysis of the uptake of 11C-5-HTP demonstrates an increase during the first minutes followed by a wash-out and a stabilization of the tissue/blood ratio at about 2. The Patlak plots demonstrated a gradual increase in the transport rate during the first 20 to 30 min, after which a constant level was observed. The SUV varied between patients and between lesions over time and treatment. The uptake of 11C-5-HTP discriminates metastatic lesions from normal bone and may thus aid in the diagnosis and, potentially, in treatment monitoring of metastatic hormone-refractory prostatic adenocarcinoma. Uptake kinetics are characterized by a wash-out and cannot alone be used as proof of neuroendocrine differentiation in hormone-refractory prostatic adenocarcinoma.

    Study Type - Prognosis inception (cohort)

    Level of Evidence 2

    What's known on the subject? and What does the study add?

    There are two randomized controlled trials showing that radiotherapy can be beneficial for men with locally advanced prostate cancer. The present study confirms the importance of curative treatment for men with high-risk prostate cancer.

    OBJECTIVE:

    •  To investigate the influence of curative treatment on cause-specific mortality in men diagnosed with prostate cancer (PCa) with serum prostate-specific antigen (PSA) levels between 20 and 100 ng/mL.

    MATERIALS AND METHODS:

    •  Patients with PCa (T1-4, N0/N1/NX, M0/MX), PSA 20-100 ng/mL and age ≤75 years were identified in the National Prostate Cancer Register of Sweden.

    •  Data on co-morbidity diagnoses were obtained from the National Patient Register and cause of death from the Cause of Death Register.

    •  Following adjustment for age at diagnosis, co-morbidity burden, Gleason score, T-category, PSA level and cause-specific mortality in relation to treatment were estimated using Cox regression analysis.

    RESULT:

    •  A total of 11 380 men were diagnosed with PCa between 1996 and 2008 and fulfilled the inclusion criteria.

    •  The cumulative 10-year PCa-specific mortality was 36% for patients receiving only palliative treatment and 13% for those treated with curative intent.

    •  For the 8462 (74%) patients with PSA levels from 20 to 50 ng/mL at diagnosis, the hazard ratio for death from PCa was 0.23 (95% confidence interval 0.19-0.27) for those treated with curative intent compared with those given palliative treatment after adjusting for age, co-morbidity, T category, PSA level and Gleason score. The corresponding hazard ratio was 0.22 (95% confidence interval 0.17-0.30) for patients with PSA levels from 51 to 100 ng/mL.

    CONCLUSION:

    •  Treatment with curative intent for men with high-risk PCa was associated with reduced cause-specific mortality and should be considered even when serum PSA exceeds 20 ng/mL.

    Health Related Quality of Life in Advanced Non Small Cell Lung Cancer: Correlates and Comparisons to Normative Data2012Inngår i: European Journal of Cancer Care, ISSN 0961-5423, E-ISSN 1365-2354, Vol. 21, nr 5, s. 642-649Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim was to describe self-reported HRQoL in patients with advanced non small cell lung cancer (NSCLC)  and to investigate the associations to stage of disease, age, gender, weight loss and performance status. Further, the study aimed to compare patients’ health related quality of life with that of the Swedish general population. Data on HRQoL were collected within a multi-centre randomised controlled trial. A total of 334 patients were included between 1998 and 2001. The EORTC QLQ-C30 and QLQ-LC13 were used to assess HRQoL. HRQoL data for comparison with the Swedish population were derived from a random sample of the Swedish population. Patients reported a markedly impaired HRQoL compared to the normal population. There were statistically and clinically significant differences with regard to almost all QLQ-C30 functional and symptom scales. Global Health Status, Physical Functioning, Role Functioning and Emotional Functioning were markedly deteriorated. The most prominent symptoms were Dyspnoea, Fatigue, Coughing, Insomnia, Appetite Loss and Pain. A low performance status, younger age, female gender and a more advanced disease were independently associated with a worse HRQoL. Additional studies are required to gain increased insight into this seriously ill group of patients and their need of supportive care.

    Characterization of the cytotoxic activity of the indoloquinoline alkaloid cryptolepine in human tumour cell lines and primary cultures of tumour cells from patients2009Inngår i: Investigational new drugs, ISSN 0167-6997, E-ISSN 1573-0646, Vol. 27, nr 5, s. 402-411Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The plant derived indoloquinoline alkaloid cryptolepine was investigated for its cytotoxic properties in 12 human tumour cell lines and in primary cultures of tumour cells from patients. The fluorometric microculture cytotoxicity assay was used to assess cytotoxicity and DNA micro-array analysis to evaluate gene expression. Cryptolepine mean IC(50) in the cell line panel was 0.9 muM compared with 1.0 and 2.8 muM in haematological and solid tumour malignancies, respectively. Among patient solid tumour samples, those from breast cancer were the most sensitive and essentially as sensitive as haematological malignancies. Cryptolepine activity showed highest correlations to topoisomerase II and microtubule targeting drugs. In the cell lines cryptolepine activity was essentially unaffected by established mechanisms of drug resistance. A number of genes were identified as associated with cryptolepine activity. In conclusion, cryptolepine shows interesting in vitro cytotoxic properties and its further evaluation as an anti-cancer drug seems warranted.

    Direct Effects of Pure Nicotine, Cigarette Smoke Extract, Swedish-type Smokeless Tobacco (Snus) Extract and Ethanol on Human Normal Endothelial Cells and Fibroblasts2011Inngår i: Anticancer Research, ISSN 0250-7005, E-ISSN 1791-7530, Vol. 31, nr 5, s. 1527-1534Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The adverse health effects of cigarette smoking are well established including the increased risk of various types of cancer. In this study, the direct effects of ethanol, pure nicotine, cigarette smoke extract and Swedish type smokeless tobacco (Snus) extract on normal cells were investigated. Materials and Methods: Primary normal adult human endothelial cells and fibroblasts at early passage were used. Upon exposure to pure nicotine, cigarette smoke extract, Snus extract and ethanol, these cells were assessed for DNA synthesis, gene expression profile and cellular morphology. Results: Normal human fibroblasts and endothelial cells have unique gene expression profiles. The effects of treatment with ethanol and nicotine from different sources was more prominent in endothelial cells than fibroblasts. The combination of alterated gene expressions and strongly inhibited DNA synthesis was only detected in cells exposed to smoke extract. In the presence and absence of ethanol, pure nicotine and Snus extract induced abnormalities in the cytoplasm without any significant degree of cell death. With similar doses of nicotine and ethanol, the additional components in smoke extract had a dominant effect. The smoke extract induced vast cellular abnormalities and massive cell death. Conclusion: Cigarette smoke induced massive cell death and various abnormalities at cellular and molecular levels in surviving endothelial cells and fibroblasts. The combination of genomic alterations and the chronic inflammatory microenvironment induced from massive cell death, will potentially promote tumourigenesis and various diseases in cigarette smokers.

    Targeting p53 in Vivo: a First-in-Human Study With p53-Targeting Compound APR-246 in Refractory Hematologic Malignancies and Prostate Cancer2012Inngår i: Journal of Clinical Oncology, ISSN 0732-183X, E-ISSN 1527-7755, Vol. 30, nr 29, s. 3633-3639Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE

    APR-246 (PRIMA-1MET) is a novel drug that restores transcriptional activity of unfolded wild-type or mutant p53. The main aims of this first-in-human trial were to determine maximum-tolerated dose (MTD), safety, dose-limiting toxicities (DLTs), and pharmacokinetics (PK) of APR-246.

    PATIENTS AND METHODS

    APR-246 was administered as a 2-hour intravenous infusion once per day for 4 consecutive days in 22 patients with hematologic malignancies and prostate cancer. Acute myeloid leukemia (AML; n = 7) and prostate cancer (n = 7) were the most frequent diagnoses. Starting dose was 2 mg/kg with dose escalations up to 90 mg/kg.

    RESULTS

    MTD was defined as 60 mg/kg. The drug was well tolerated, and the most common adverse effects were fatigue, dizziness, headache, and confusion. DLTs were increased ALT/AST (n = 1), dizziness, confusion, and sensory disturbances (n = 2). PK showed little interindividual variation and were neither dose nor time dependent; terminal half-life was 4 to 5 hours. Tumor cells showed cell cycle arrest, increased apoptosis, and upregulation of p53 target genes in several patients. Global gene expression analysis revealed changes in genes regulating proliferation and cell death. One patient with AML who had a p53 core domain mutation showed a reduction of blast percentage from 46% to 26% in the bone marrow, and one patient with non-Hodgkin's lymphoma with a p53 splice site mutation showed a minor response.

    CONCLUSION

    We conclude that APR-246 is safe at predicted therapeutic plasma levels, shows a favorable pharmacokinetic profile, and can induce p53-dependent biologic effects in tumor cells in vivo.

    Human cytomegalovirus tegument protein pp65 is detected in all intra- and extra-axial brain tumours independent of the tumour type or grade2014Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 9, nr 9, s. e108861-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Human cytomegalovirus (HCMV) has been indicated being a significant oncomodulator. Recent reports have suggested that an antiviral treatment alters the outcome of a glioblastoma. We analysed the performance of commercial HCMV-antibodies applying the immunohistochemical (IHC) methods on brain sample obtained from a subject with a verified HCMV infection, on samples obtained from 14 control subjects, and on a tissue microarray block containing cores of various brain tumours. Based on these trials, we selected the best performing antibody and analysed a cohort of 417 extra- and intra-axial brain tumours such as gliomas, medulloblastomas, primary diffuse large B-cell lymphomas, and meningiomas. HCMV protein pp65 immunoreactivity was observed in all types of tumours analysed, and the IHC expression did not depend on the patient's age, gender, tumour type, or grade. The labelling pattern observed in the tumours differed from the labelling pattern observed in the tissue with an active HCMV infection. The HCMV protein was expressed in up to 90% of all the tumours investigated. Our results are in accordance with previous reports regarding the HCMV protein expression in glioblastomas and medulloblastomas. In addition, the HCMV protein expression was seen in primary brain lymphomas, low-grade gliomas, and in meningiomas. Our results indicate that the HCMV protein pp65 expression is common in intra- and extra-axial brain tumours. Thus, the assessment of the HCMV expression in tumours of various origins and pathologically altered tissue in conditions such as inflammation, infection, and even degeneration should certainly be facilitated.

    Both CD4(+) FoxP3(+) and CD4(+) FoxP3(-) T cells from patients with B-cell malignancy express cytolytic markers and kill autologous leukaemic B cells in vitro.2011Inngår i: Immunology, ISSN 0019-2805, E-ISSN 1365-2567, Vol. 133, nr 3, s. 296-306Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    P>Cytotoxic CD4+ T cells have been found in patients with chronic lymphocytic leukaemia (CLL) and seem to be involved in the regulation of malignant B cells. The CD4+ T regulatory cells (Tregs) can regulate various immune cells, including B cells, by inducing their apoptosis. Hence, different subgroups of CD4+ T cells may be involved in the regulation of malignant B cells. In this study, the cytotoxic phenotype and function of various CD4+ T-cell subgroups were investigated in patients with B-cell malignancies. Peripheral blood was collected from patients with CLL, various B-cell lymphomas, healthy adult donors, children with precursor B-cell acute lymphoblastic leukaemia (pre-B ALL) and from healthy children. CD4+ T cells (CD3+ CD4+ FoxP3-), Tregs (CD3+ CD4+ CD127low FoxP3+) and CD127high FoxP3+ T cells (CD3+ CD4+ CD127high FoxP3+) were analysed for their expression of the cytolytic markers CD107a and Fas ligand. Patients with CLL had increased CD107a expression on all tested T-cell subgroups compared with healthy donors. Similar results were found in patients with B-cell lymphomas whereas the CD107a expression in children with pre-B ALL was no different from that in healthy controls. Fas ligand expression was similar between patient cells and cells of healthy donors. CD4+ T cells and Tregs from patients with CLL and healthy donors were subsequently purified and cultured in vitro with autologous B cells. Both subgroups lysed B cells and killing was confirmed by granzyme ELISAs. In conclusion, cytotoxic populations of CD4+ T cells, including Tregs, are present in patients with B-cell malignancy and may be an important factor in immune-related disease control.

    A population-based cohort study on adherence to practice guidelines for adjuvant chemotherapy in colorectal cancer2014Inngår i: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 14, s. 948-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The value of adjuvant chemotherapy in colorectal cancer is well studied, and guidelines have been established. Little is known about how treatment guidelines are implemented in the everyday clinical setting. Methods: This national population-based study on nearly 34,000 patients with colorectal cancer evaluates the adherence to present clinical guidelines for adjuvant chemotherapy. Virtually all patients with colorectal cancer in Sweden during the years 2007-2012 and data from the Swedish Colorectal Cancer Registry were included. Results: In colon cancer stage III, adherence to national guidelines was associated with lower age, presence of multidisciplinary team (MDT) conference, low co-morbidity, and worse N stage. The MDT forum also affected whether or not high-risk stage II colon cancer patients were considered for adjuvant chemotherapy. Rectal cancer patients both in stage II and III were considered for adjuvant chemotherapy less often than colon cancer patients, but the same factors influenced the decision. Adjuvant chemotherapy was started later than eight weeks after surgery in 30% of colon cancer patients and in 38% of rectal cancer patients. Conclusions: In Sweden, the adherence to national guidelines for adjuvant chemotherapy in colon cancer stage III is acceptable in younger and healthier patients. MDT conferences are of major importance and affect whether patients are recommended for adjuvant chemotherapy. Special consideration needs to be given to certain subgroups of patients, particularly older patients and patients with poorly differentiated tumors. There is a need to shorten the waiting time until start of chemotherapy.

    The prognostic relevance of tumour-infiltrating plasma cells and immunoglobulin kappa C indicates an important role of the humoral immune response in non-small cell lung cancer2013Inngår i: Cancer Letters, ISSN 0304-3835, E-ISSN 1872-7980, Vol. 333, nr 2, s. 222-228Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A prognostic impact of immunoglobulin kappa C (IGKC) expression has been described in cancer. We analysed the influence of B-cell and plasma cell markers, as well as IGKC expression, in non-small lung cancer (NSCLC) using immunohistochemistry on a tissue microarray. IGKC protein expression was independently associated with longer survival, with particular impact in the adenocarcinoma subgroup. Moreover, a correlation was seen with CD138+ cells, but not with CD20. CD138 expression revealed a comparable association with survival. In conclusion, IGKC expression in stroma–infiltrating plasma cells is a prognostic marker in NSCLC, supporting emerging treatment concepts that exploit the humoral immune response.

    Changes in health-related quality of life by occupational status among women diagnosed with breast cancer: a population-based cohort study2013Inngår i: Psycho-Oncology, ISSN 1057-9249, E-ISSN 1099-1611, Vol. 22, nr 10, s. 2321-2331Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective:

    To investigate whether longitudinal changes in health-related quality of life (HRQoL) among breast cancer patients vary by prediagnosis occupational status or postdiagnosis changes in working time.

    Methods:

    We identified 1573 patients in the Breast Cancer Quality Register of Central Sweden and asked them to participate in a longitudinal questionnaire study. A total of n = 841 women completed three questionnaires within a mean time of 4, 16, and 38 months postdiagnosis. Generalized estimating equation models were used to examine changes in European Organization for Research and Treatment of Cancer Quality of Life Questionnaire and the Breast Cancer-Specific Quality of Life Questionnaire subscales stratified by prediagnosis occupational status and postdiagnosis changes in working time.

    Results:

    Over time, the proportion of employed women reporting good functioning increased more, and the proportion reporting a high level of symptoms decreased more compared with women on sick leave/disability pension and retirement pensioners (p < 0.001). The latter two also showed a worsening in several subscales (p < 0.05). Among employed women, more consistent improvements in role and social functioning were observed among those with an increase/no change in working time than among those who had decreased it or stopped working (p < 0.05). A decrease in the proportion reporting pain was observed among women with an increase/no change in working time compared with women with decreased working time, among whom the proportion reporting pain increased (p = 0.008).

    Conclusions:

    Being employed prediagnosis and resuming work to the same extent as prior to the breast cancer diagnosis are associated with consistent improvements in HRQoL. These results highlight the importance of interventions to improve HRQoL and policies to support return to work following diagnosis.

    Sickness absence and disability pension following breast cancer: A population-based matched cohort study2014Inngår i: Breast, ISSN 0960-9776, E-ISSN 1532-3080, Vol. 23, nr 6, s. 844-851Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To compare sickness absence and disability pension in a population-based cohort of women with breast cancer (n = 463) from 1 year pre-diagnosis until 3 years post-diagnosis with a matched control group (n = 2310), and to investigate predictors of sickness absence during the 2nd and 3rd year post-diagnosis.

    Results: Following breast cancer, the proportion of disease-free women with sickness absence decreased post-diagnosis (1st - 3rd year; 78%-31%-19%), but did not reach the pre-diagnostic level (14%; P < 0.05). Post-diagnosis, patients were more likely than controls to be sickness absent (1st - 3rd year; P < 0.001). No between-group differences were observed for disability pension post-diagnosis (P > 0.05). Among patients, chemotherapy, baseline fatigue and pre-diagnosis sick days predicted sickness absence during the 2nd, 3rd, and 2nd and 3rd year post-diagnosis, respectively (P < 0.05).

    Conclusions: Breast cancer is associated with increased sickness absence 3 years post-diagnosis. In a clinical setting, prevention and treatment of side effects are important in reducing long-term consequences.

    Abstract [en]

    Background Survival and prognostic factors for thin melanomas have been studied relatively little in population-based settings. This patient group accounts for the majority of melanomas diagnosed in western countries today, and better prognostic information is needed. Objectives The aim of this study was to use established prognostic factors such as ulceration, tumour thickness and Clark's level of invasion for risk stratification of T1 cutaneous melanoma. Methods From 1990 to 2008, the Swedish Melanoma Register included 97% of all melanomas diagnosed in Sweden. Altogether, 13 026 patients with T1 melanomas in clinical stage I were used for estimating melanoma-specific 10- and 15-year mortality rates. The Cox regression model was used for further survival analysis on 11 165 patients with complete data. Results Ulceration, tumour thickness and Clark's level of invasion all showed significant, independent, long-term prognostic information. By combining these factors the patients could be subdivided into three risk groups: a low-risk group (67.9% of T1 cases) with a 10-year melanoma-specific mortality rate of 1.5% (1.2-1.9%); an intermediate-risk group (28.6% of T1 cases) with a 10-year mortality rate of 6.1% (5.0-7.3%); and a high-risk group (3.5% of T1 cases) with a 10-year mortality rate of 15.6% (11.2-21.4%). The high-and intermediate-risk groups accounted for 66% of melanoma deaths within T1. Conclusions Using a population-based melanoma register, and combining ulceration, tumour thickness and Clark's level of invasion, three distinct prognostic subgroups were identified.

    Inflammatory cells in node-negative breast cancer2012Inngår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 51, nr 5, s. 680-686Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background.

    To study the impact of inflammatory cells in a clinically well-defined cohort of women with node-negative breast cancer in a nested case-control study design.

    Material and methods.

    The cohort was comprised of 190 women who died from breast cancer and 190 women still alive at the date of death for the corresponding breast cancer patients were used as controls. The inclusion criteria included; a tumour size ≤ 50 mm, no lymph node metastases and no initiation of adjuvant chemotherapy. Immunohistochemical stainings for CD3, CD4, CD8, FoxP3, CD20, tryptase and CD68 were performed on TMA blocks, evaluated and correlated to each other and to age, tumour size, histological grade, ER, PgR, Ki67 and cyclin A.

    Results.

    There was no difference regarding the amount or content of inflammatory cells in the cases compared to controls. T- and B-cells were highly correlated to each other but these cell types correlated to a lesser extent to macrophages and not at all to mast cells. A weak tendency of correlations between all the subsets of inflammatory cells and histological grade, Ki67 and cyclin A was observed, although a negative correlation was seen for mast cells.

    Conclusion.

    The amount or content of inflammatory cells in invasive breast cancer did not appear to influence death in node-negative breast cancer.

    SATB2 in Combination With Cytokeratin 20 Identifies Over 95% of all Colorectal Carcinomas2011Inngår i: American Journal of Surgical Pathology, ISSN 0147-5185, E-ISSN 1532-0979, Vol. 35, nr 7, s. 937-948Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The special AT-rich sequence-binding protein 2 (SATB2), a nuclear matrix-associated transcription factor and epigenetic regulator, was identified as a tissue type-specific protein when screening protein expression patterns in human normal and cancer tissues using an antibody-based proteomics approach. In this respect, the SATB2 protein shows a selective pattern of expression and, within cells of epithelial lineages, SATB2 expression is restricted to glandular cells lining the lower gastrointestinal tract. The expression of SATB2 protein is primarily preserved in cancer cells of colorectal origin, indicating that SATB2 could function as a clinically useful diagnostic marker to distinguish colorectal cancer (CRC) from other types of cancer. The aim of this study was to further explore and validate the specific expression pattern of SATB2 as a clinical biomarker and to compare SATB2 with the well-known cytokeratin 20 (CK20). Immunohistochemistry was used to analyze the extent of SATB2 expression in tissue microarrays with tumors from 9 independent cohorts of patients with primary and metastatic CRCs (n = 1882). Our results show that SATB2 is a sensitive and highly specific marker for CRC with distinct positivity in 85% of all CRCs, and that SATB2 and/or CK20 was positive in 97% of CRCs. In conclusion, the specific expression of SATB2 in a large majority of CRCs suggests that SATB2 can be used as an important complementary tool for the differential diagnosis of carcinoma of unknown primary origin.

    Comparative evaluation of synthetic anti-HER2 Affibody molecules site-specifically labelled with 111In using N-terminal DOTA, NOTA and NODAGA chelators in mice bearing prostate cancer xenografts.2012Inngår i: European Journal of Nuclear Medicine and Molecular Imaging, ISSN 1619-7070, E-ISSN 1619-7089, Vol. 39, nr 3, s. 481-492Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: In disseminated prostate cancer, expression of human epidermal growth factor receptor type 2 (HER2) is one of the pathways to androgen independence. Radionuclide molecular imaging of HER2 expression in disseminated prostate cancer might identify patients for HER2-targeted therapy. Affibody molecules are small (7 kDa) targeting proteins with high potential as tracers for radionuclide imaging. The goal of this study was to develop an optimal Affibody-based tracer for visualization of HER2 expression in prostate cancer.

    METHODS: A synthetic variant of the anti-HER2 Z(HER2:342) Affibody molecule, Z(HER2:S1), was N-terminally conjugated with the chelators DOTA, NOTA and NODAGA. The conjugated proteins were biophysically characterized by electrospray ionization mass spectroscopy (ESI-MS), circular dichroism (CD) spectroscopy and surface plasmon resonance (SPR)-based biosensor analysis. After labelling with (111)In, the biodistribution was assessed in normal mice and the two most promising conjugates were further evaluated for tumour targeting in mice bearing DU-145 prostate cancer xenografts.

    RESULTS: The HER2-binding equilibrium dissociation constants were 130, 140 and 90 pM for DOTA-Z(HER2:S1), NOTA-Z(HER2:S1) and NODAGA-Z(HER2:S1), respectively. A comparative study of (111)In-labelled DOTA-Z(HER2:S1), NOTA-Z(HER2:S1) and NODAGA-Z(HER2:S1) in normal mice demonstrated a substantial influence of the chelators on the biodistribution properties of the conjugates. (111)In-NODAGA-Z(HER2:S1) had the most rapid clearance from blood and healthy tissues. (111)In-NOTA-Z(HER2:S1) showed high hepatic uptake and was excluded from further evaluation. (111)In-DOTA-Z(HER2:S1) and (111)In-NODAGA-Z(HER2:S1) demonstrated specific uptake in DU-145 prostate cancer xenografts in nude mice. The tumour uptake of (111)In-NODAGA-Z(HER2:S1), 5.6 ± 0.4%ID/g, was significantly lower than the uptake of (111)In-DOTA-Z(HER2:S1), 7.4 ± 0.5%ID/g, presumably because of lower bioavailability due to more rapid clearance. (111)In-NODAGA-Z(HER2:S1) provided higher tumour-to-blood ratio, but somewhat lower tumour-to-liver, tumour-to-spleen and tumour-to-bone ratios.

    CONCLUSION: Since distant prostate cancer metastases are situated in bone or bone marrow, the higher tumour-to-bone ratio is the most important. This renders (111)In-DOTA-Z(HER2:S1) a preferable agent for imaging of HER2 expression in disseminated prostate cancer.

    Comparative biodistribution of imaging agents for in vivo molecular profiling of disseminated prostate cancer in mice bearing prostate cancer xenografts: focus on (111)In- and (125)I-labeled anti-HER2 humanized monoclonal trastuzumab and ABY-025 Affibody2011Inngår i: Nuclear Medicine and Biology, ISSN 0969-8051, E-ISSN 1872-9614, Vol. 38, nr 8, s. 1093-1102Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction: Human epidermal growth factor receptor type 2 (HER2) overexpression supports proliferation of androgen-independent prostate cancer (PC). Radionuclide molecular imaging of HER2 expression in disseminated PC would aid in the selection of patients who are likely responders to HER2 targeting therapy. In this study, we evaluated whether ABY-025 Affibody molecule, a small (similar to 7-kDa) HER2-binding scaffold protein, produces superior tumor-to-nontumor ratios compared with those obtained through the use of radiolabeled humanized anti-HER2 antibody, trastuzumab. The influence of (111)In vs. (125)I radiolabel was evaluated for both tracers.

    Methods: ABY-025 was labeled with (111)In using 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid chelator, site-specifically coupled to the C-terminus via the maleimido derivative. Trastuzumab was labeled with (111)In using a CHX-A" diethylene triamine pentaacetic acid (DTPA) chelator. An indirect radioiodination with [(125)I]-N-succinimidyl-para-iodobenzoate was used for both targeting proteins. Biodistribution of all labeled targeting proteins was evaluated in mice bearing DU-145 PC xenografts.

    Results: The use of residualizing (111)In-label facilitated better tumor uptake and better tumor-to-nontumor ratios for both targeting agents. [(111)In]-ABY-025 provided tumor uptake of 7.1 +/- 0.8% injected dose per gram of tissue (% ID/g) and tumor-to-blood ratio of 47 +/- 13 already at 6 h postinjection. The maximum tumor-to-nontumor ratios with [(111)In]-CHX-DTPA-trastuzumab were achieved at 72 h postinjection, whereas tumor uptake was 11 +/- 4% ID/g and tumor-to-blood ratio was 18 +/- 7. The biodistribution data were confirmed with gamma-camera imaging.

    Conclusions: Radiolabeled ABY-025 Affibody molecule provides higher contrast in imaging of HER2-expressing PC xenografts than radiolabeled trastuzumab. Residualizing radiometal label for ABY-025 provides better contrast in imaging of HER2-expressing PC xenografts than nonresidualizing radiohalogen.

    A randomised feasibility/phase II study (SBG 2004-1) with dose-dense/tailored epirubicin, cyclophoshamide (EC) followed by docetaxel (T) or fixed dosed dose-dense EC/T versus T, doxorubicin and C (TAC) in node-positive breast cancer2011Inngår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 50, nr 1, s. 35-41Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of the study was to evaluate the feasibility of tailored and dose-dense epirubicin and cyclophosphamide followed by docetaxel as adjuvant breast cancer therapy. Material and methods. Patients with node-positive breast cancer received either four cycles of biweekly and tailored EC (epirubicin 38-60-75-90-105-120 mg/m(2), cyclophosphamide 450-600-900-1200 mg/m(2)) followed by four cycles of docetaxel (60-75-85-100 mg/m(2)) (arm A) or the same regimen with fixed doses (E90C600 x 4 -> T-75 x 4) (arm B) or docetaxel, doxorubicin and cyclophosphamide (T(75)A(50)C(500)) every three weeks for six cycles (arm C). All patients received G-CSF support and prophylactic ciprofloxacin. Results. One-hundred and twenty-four patients were randomised in the study. In the A, B and C arm, 17% 19% and 3% of the patients had one or more cycles delayed due to side-effects whereas 24%, 5% and 15% experienced a grade 3 infection or febrile neutropenia. After the introduction of an extra week between the EC and T parts in the A and B arms, grade 3 hand-foot-skin reactions were reduced from 5 to 0.2%. Twenty-nine percent (A and B) and 20% (C) of the patients were hospitalised due to side-effects. Discussion. Dose-dense and tailored EC/T can be given with manageable toxicity and is after adjustment presently studied in the phase III Panther trial.

    Internet-based stepped care with interactive support and cognitive behavioral therapy for reduction of anxiety and depressive symptoms in cancer: a clinical trial protocol2013Inngår i: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 13, s. 414-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Approximately 20-30% of patients with cancer experience a clinically relevant level of emotional distress in response to disease and treatment. This in itself is alarming but it is even more problematic because it is often difficult for physicians and nurses to identify cancer patients who experience clinically relevant levels of anxiety and depression symptoms. This can result in persistent distress and can cause human suffering as well as costs for individuals and to the community. Methods: Applying a multi-disciplinary and design-oriented approach aimed at attaining new evidence-based knowledge in basic and applied psychosocial oncology, this protocol will evaluate an intervention to be implemented in clinical practice to reduce cancer patient anxiety and depression. A prospective randomized design will be used. The overarching goal of the intervention is to promote psychosocial health among patients suffering from cancer by means of self-help programmes delivered via an Internet platform. Another goal is to reduce costs for individuals and society, caused by emotional distress in response to cancer. Following screening to detect levels of patient distress, patients will be randomized to standard care or a stepped care intervention. For patients randomized to the intervention, step 1 will consist of self-help material, a chat forum where participants will be able to communicate with each other, and a Frequently Asked Questions (FAQ) section where they can ask questions and get answers from an expert. Patients in the intervention group who still report symptoms of anxiety or depression after access to step 1 will be offered step 2, which will consist of cognitive behavioral therapy (CBT) administered by a personal therapist. The primary end point of the study is patients' levels of anxiety and depression, evaluated longitudinally during and after the intervention. Discussion: There is a lack of controlled studies of the psychological and behavioral processes involved in this type of intervention for anxiety and depressive disorders. Since anxiety and depressive symptoms are relatively common in patients with cancer and the availability of adequate support efforts is limited, there is a need to develop evidence-based stepped care for patients with cancer, to be delivered via the Internet.

    Background: The clinical behaviour of colon cancer is heterogeneous. Five-year overall survival is 50-65% with all stages included. Recurring somatic chromosomal alterations have been identified and some have shown potential as markers for dissemination of the tumour, which is responsible for most colon cancer deaths. We investigated 115 selected stage II-IV primary colon cancers for associations between chromosomal alterations and tumour dissemination. Methods: Follow-up was at least 5 years for stage II-III patients without distant recurrence. Affymetrix SNP 6.0 microarrays and allele-specific copy number analysis were used to identify chromosomal alterations. Fisher's exact test was used to associate alterations with tumour dissemination, detected at diagnosis (stage IV) or later as recurrent disease (stage II-III). Results: Loss of 1p36.11-21 was associated with tumour dissemination in microsatellite stable tumours of stage II-IV (odds ratio = 5.5). It was enriched to a similar extent in tumours with distant recurrence within stage II and stage III subgroups, and may therefore be used as a prognostic marker at diagnosis. Loss of 1p36.11-21 relative to average copy number of the genome showed similar prognostic value compared to absolute loss of copies. Therefore, the use of relative loss as a prognostic marker would benefit more patients by applying also to hyperploid cancer genomes. The association with tumour dissemination was supported by independent data from the The Cancer Genome Atlas. Conclusion: Deletions on 1p36 may be used to guide adjuvant treatment decisions in microsatellite stable colon cancer of stages II and III.

    The clinical safety, biodistribution and internal radiation dosimetry of [F-18]fluciclovine in healthy adult volunteers2013Inngår i: European Journal of Nuclear Medicine and Molecular Imaging, ISSN 1619-7070, E-ISSN 1619-7089, Vol. 40, nr 8, s. 1256-1264Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    We report on the biodistribution and internal radiation dosimetry in humans of [F-18]fluciclovine, a synthetic L-leucine analogue being investigated as a potential diagnostic biomarker for neoplasia. Whole-body positron emission tomography (PET) scans of 6 healthy volunteers were acquired at up to 16 time points up to about 5 h after a bolus administration of [F-18]fluciclovine (153.8 +/- 2.2 MBq). Venous blood samples were taken up to about 4 h post-injection from which F-18 activity concentrations in whole blood and plasma were measured. Urine was collected as voided up to 4 h post-injection, from which the excreted F-18 activity was measured. Absolute values of the F-18 activity contained in up to 11 source regions (brain, salivary glands, lung, heart, pancreas, spleen, liver, red bone marrow, kidneys, uterus and urinary bladder contents) were determined directly from quantitative analysis of the images. For each source region, the F-18 activity decay-corrected and normalised to that injected, as a function of time, was fit by an analytical function which was subsequently integrated to yield the cumulated activity normalised to the injected activity. These normalised cumulated activities were then used as input to the Organ Level INternal Dose Assessment/EXponential Modelling (OLINDA/EXM) package to calculate the internal radiation dosimetry of each subject following the Medical Internal Radiation Dose (MIRD) schema. An effective dose was then estimated for each subject. [F-18]Fluciclovine was clinically well tolerated in this study. Very little F-18 was excreted with only a mean value of 3.3 % present in the urine at about 4 h post-injection; no activity within the intestinal contents was noted. The highest mean initial uptakes were measured in the liver (13.8 %), red bone marrow (11.1 %) and lung (7.1 %). The highest mean radiation absorbed doses per unit administered activity were received by the pancreas (102.2 mu Gy/MBq), the cardiac wall (51.7 mu Gy/MBq) and the uterine wall (44.6 mu Gy/MBq). The mean effective dose per unit administered activity was 22.1 mu Sv/MBq. The internal radiation dosimetry of [F-18]fluciclovine appears acceptable for PET imaging.

    Gene Copy Number Aberrations Are Associated with Survival in Histologic Subgroups of Non-small Cell Lung Cancer2011Inngår i: Journal of Thoracic Oncology, ISSN 1556-0864, E-ISSN 1556-1380, Vol. 6, nr 11, s. 1833-1840Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Introduction:

    Non-small cell lung cancer (NSCLC) is characterized by a multitude of genetic aberrations with unknown clinical impact. In this study, we aimed to identify gene copy number changes that correlate with clinical outcome in NSCLC. To maximize the chance to identify clinically relevant events, we applied a strategy involving two prognostically extreme patient groups.

    Methods:

    Short-term (<20 month; n = 53) and long-term survivors (>58 month; n = 47) were selected from a clinically well-characterized NSCLC patient cohort with available fresh frozen tumor specimens. The samples were analyzed using high-resolution single-nucleotide polymorphism array technology to assess gene copy number variations and array-based gene expression profiling. The molecular data were combined with information on clinical parameters.

    Results:

    Genetic aberrations were strongly associated with tumor histology. In adenocarcinoma (n = 50), gene copy number gains on chromosome 8q21-q24.3 (177 genes) were more frequent in long-term than in short-term survivors. In squamous cell carcinoma (n = 28), gains on chromosome 14q23.1-24.3 (133 genes) were associated with shorter survival, whereas losses in a neighboring region, 14q31.1-32.33 (110 genes), correlated with favorable outcome. In accordance with copy number gains and losses, messenger RNA expression levels of corresponding genes were increased or decreased, respectively.

    Conclusion:

    Comprehensive tumor profiling permits the integration of genomic, histologic, and clinical data. We identified gene copy number gains and losses, with corresponding changes in messenger RNA levels that were associated with prognosis in adenocarcinoma and squamous cell carcinoma of the lung.
