    The Nordic SentiMag trial: a comparison of super paramagnetic iron oxide (SPIO) nanoparticles versus Tc-99 and patent blue in the detection of sentinel node (SN) in patients with breast cancer and a meta-analysis of earlier studies2016Ingår i: Breast Cancer Research and Treatment, ISSN 0167-6806, E-ISSN 1573-7217, Vol. 157, nr 2, s. 281-294Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the study is to compare the efficacy of SPIO as a tracer in sentinel node biopsy (SNB) in breast cancer with Tc and patent blue in a multicentre prospective study and perform a meta-analysis of all published studies. It also aims to follow skin discoloration after SPIO injection and describe when and how it resolves. Totally 206 patients with early breast cancer were recruited. Tc and patent blue were administered in standard fashion. Patients were injected with SPIO (Sienna+) preoperatively. SNB was performed and detection rates were recorded for both methods. Skin discoloration was followed and documented postoperatively. Data extraction and subsequent meta-analysis of all previous studies were also performed. SN detection rates were similar between standard technique succeeded and SPIO both per patient (97.1 vs. 97.6 %, p = 0.76) as well as per node (91.3 vs. 93.3 %, p = 0.34), something which was not affected by the presence of malignancy. Concordance rates were also consistently high (98.0 % per patient and 95.9 % per node). Discoloring was present in 35.5 % of patients postoperatively, almost exclusively in breast conservation. It fades slowly and is still detectable in 8.6 % of patients after 15 months. Meta-analysis depicted similar detection rates (p = 0.71) and concordance rates (p = 0.82) per patient. However, it seems that SPIO is characterized by higher nodal retrieval (p < 0.001). SPIO is an effective method for the detection of SN in patients with breast cancer. It is comparable to the standard technique and seems to simplify logistics. Potential skin discoloration is something of consideration in patients planned for breast conservation.

    Superparamagnetic iron oxide nanoparticles as the sole method for sentinel node biopsy detection in patients with breast cancer2017Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 104, nr 12, s. 1675-1685Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Sentinel node biopsy (SNB) using superparamagnetic iron oxide (SPIO) nanoparticles is a novel method in breast cancer. Several studies have verified the non-inferiority of SPIO compared with the standard use of radioisotope (99m) Tc with or without blue dye. The aim of the MONOS study presented here was to evaluate the use of SPIO as a sole tracer and the efficacy of tracer injection in the preoperative setting.

    METHODS: This prospective cohort study was carried out in two hospitals, one using (99m) Tc and the other SPIO. (99m) Tc was injected in the morning of the day of surgery or the day before. SPIO was either injected before surgery in the outpatient clinic or 1 h before the operation.

    RESULTS: A total of 338 consecutive patients with breast cancer underwent 343 procedures; SPIO nanoparticles were used in 184 procedures and (99m) Tc-labelled tracer in 159. Detection rates for SPIO and (99m) Tc were 95·6 and 96·9 per cent respectively (P = 0·537). All nodes with SPIO uptake were coloured brown. Fewer nodes were retrieved with SPIO (mean 1·35 versus 1·89), regardless of whether blue dye was used (P < 0·001). Preoperative SPIO injection (58·7 per cent of procedures), a median of 16 (range 2-27) days before the procedure, was associated with a better tracer-specific detection rate (95·3 versus 86 per cent; P = 0·031) and retrieval of more nodes (mean 1·43 versus 1·03; P < 0·001) than perioperative administration. Skin staining was present in 39·9 per cent of patients, and was related to breast-conserving surgery and periareolar injection.

    CONCLUSION: The use of SPIO alone is a safe alternative, with results comparable to those of the standard dual technique using (99m) Tc and blue dye. The efficacy of injection in the preoperative setting simplifies logistics and improves performance. Skin staining can be prevented by a deeper peritumoral injection.

    Effect of preoperative injection of superparamagnetic iron oxide particles on rates of sentinel lymph node dissection in women undergoing surgery for ductal carcinoma in situ (SentiNot study)2019Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 106, nr 6, s. 720-728Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: One-fifth of patients with a preoperative diagnosis of ductal carcinoma in situ (DCIS) have invasive breast cancer (IBC) on definitive histology. Sentinel lymph node dissection (SLND) is performed in almost half of women having surgery for DCIS in Sweden. The aim of the present study was to try to minimize unnecessary SLND by injecting superparamagnetic iron oxide (SPIO) nanoparticles at the time of primary breast surgery, enabling SLND to be performed later, if IBC is found in the primary specimen.

    Methods: Women with DCIS at high risk for the presence of invasion undergoing breast conservation, and patients with DCIS undergoing mastectomy were included. The primary outcome was whether this technique could reduce SLND. Secondary outcomes were number of SLNDs avoided, detection rate and procedure-related costs.

    Results: This was a preplanned interim analysis of 189 procedures. IBC was found in 47 and a secondary SLND was performed in 41 women. Thus, 78.3 per cent of patients avoided SLND (P<0.001). At reoperation, SPIO plus blue dye outperformed isotope and blue dye in detection of the sentinel node (40 of 40 versus 26 of 40 women; P<0.001). Costs were reduced by a mean of 24.5 per cent in women without IBC (3990 versus 5286; P<0.001).

    Conclusion: Marking the sentinel node with SPIO in women having surgery for DCIS was effective at avoiding unnecessary SLND in this study. Registration number: ISRCTN18430240 (http://www.isrctn.com).

    Simplifying Logistics and Avoiding the Unnecessary in Patients with Breast Cancer Undergoing Sentinel Node Biopsy. A Prospective Feasibility Trial of the Preoperative Injection of Super Paramagnetic Iron Oxide Nanoparticles2018Ingår i: Scandinavian Journal of Surgery, ISSN 1457-4969, E-ISSN 1799-7267, Vol. 107, nr 2, s. 130-137Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    PURPOSE: Sentinel node is routinely localized with the intraoperative use of a radioactive tracer, involving challenging logistics. Super paramagnetic iron oxide nanoparticle is a non-radioactive tracer with comparable performance that could allow for preoperative localization, would simplify the procedure, and possibly be of value in axillary mapping before neoadjuvant treatment. The current trial aimed to determine the a priori hypothesis that the injection of super paramagnetic iron oxide nanoparticles in the preoperative period for the localization of the sentinel node is feasible.

    METHODS: This is a prospective feasibility trial, conducted from 9 September 2014 to 22 October 2014 at Uppsala University Hospital. In all, 12 consecutive patients with primary breast cancer planned for resection of the primary and sentinel node biopsy were recruited. Super paramagnetic iron oxide nanoparticles were injected in the preoperative visit in the outpatient clinic. The radioactive tracer (99mTc) and the blue dye were injected perioperatively in standard fashion. A volunteer was injected with super paramagnetic iron oxide nanoparticles to follow the decline in the magnetic signal in the sentinel node over time. The primary outcome was successful sentinel node detection.

    RESULTS: Super paramagnetic iron oxide nanoparticles' detection after preoperative injection (3-15 days) was successful in all cases (100%). In the volunteer, axillary signal was presented for 4 weeks. No adverse effects were noted. Conclusion and relevance: Preoperative super paramagnetic iron oxide nanoparticles' injection is feasible and leads to successful detection of the sentinel node. That may lead to simplified logistics as well as the identification, sampling, and marking of the sentinel node in patients planned for neoadjuvant treatment.

    Meta-analysis of neoadjuvant therapy and its impact in facilitating breast conservation in operable breast cancer2018Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 105, nr 5, s. 469-481Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    Neoadjuvant therapy (NAT) for operable breast cancer may facilitate more breast-conserving surgery (BCS). It seems, however, that this benefit is not being realized fully.

    Methods

    A systematic review of the literature was performed. RCTs were included. The criteria for inclusion were: documentation of surgical assessment before and after NAT, surgery performed (BCS or mastectomy), and clinical and pathological responses.

    Results

    A total of 1452 patients from seven RCTs met the inclusion criteria. After NAT, the feasibilityof BCS increased from 43⋅3to60⋅4 per cent (P < 0⋅001), but BCS was performed in only 51⋅8percent(P = 0⋅04). Only 31 per cent of patients who became eligible for BCS (assessed on clinical response)underwent BCS (pooled rate ratio 0⋅31, 95 per cent c.i. 0⋅22 to 0⋅44; P < 0⋅001). Of the mastectomycandidates who achieved a pathological complete response after NAT, only 41 per cent underwent BCS(pooled rate ratio 0⋅41, 0⋅23 to 0⋅74; P = 0⋅003). The main factors that influenced the decision not to shiftto BCS, even though it was feasible, were clinical assessment before NAT, multicentricity and tumoursize at presentation.

    Conclusion

    Breast surgery performed after NAT does not reflect tumour response, resulting in potentially unnecessary radical surgery, especially mastectomy. The barriers to maximizing the surgical benefits of NAT need to be better understood and explored. Still unnecessary mastectomies

    Efficiency of percutaneous core biopsy in pancreatic tumor diagnosis1996Ingår i: Surgery, ISSN 0039-6060, E-ISSN 1532-7361, Vol. 120, nr 1, s. 75-79Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    Radiologic diagnosis of pancreatic tumors exhibits limited precision. The aim of this study was to investigate the outcome and complications of pancreatic core biopsy in patients with suspected pancreatic neoplasms.

    METHODS:

    One hundred patients underwent ultrasonography-guided core biopsy of 1.2 mm external diameter. Medical charts were examined for biochemical and clinical signs of complications. Final diagnosis was settled by operation, autopsy, and clinical signs of the disease including survival with at least 2.3 years of follow-up.

    RESULTS:

    Histopathologic biopsy evaluation showed correct discrimination between exocrine and endocrine tumors and nonneoplastic conditions in 89 patients. No false-positive cancer diagnosis was found, and guidance on nature of primary tumors was obtained for eight of eight metastases. The sensitivity was 91% for exocrine and 87% for endocrine pancreatic tumors, and negative predictive values of these diagnoses were 83% and 97%, respectively. No clinically significant complications were noted.

    CONCLUSIONS:

    Core biopsy is an attractive alternative to diagnostic laparotomy in unresectable pancreatic cancer and efficiently provides diagnosis of endocrine tumors and pancreatic metastases in conjunction with rare complications. Benign biopsy findings cannot be used to exclude presence of primary or metastatic pancreatic neoplasms.

    No breast cancer subgroup can be spared postoperative radiotherapy after breast-conserving surgery. Fifteen-year results from the Swedish Breast Cancer Group randomised trial, SweBCG 91 RT2016Ingår i: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 67, s. 57-65Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Breast-conserving surgery (BCS) followed by radiotherapy (RT) is an established treatment for women with T1-2N0 breast cancers. Since subgroups of patients have low ipsilateral breast tumour recurrence (IBTR) rates, it is important to study whether RT is necessary for all patients. Patients and methods: A total of 1187 women with primary T1-2N0M0 breast cancer were randomised, after standardised sector resection, to postoperative whole breast RT or no local treatment. Adjuvant systemic therapy was offered to patients with stage II cancers. Patients were followed with clinical examinations and annual mammography for 10 years and thereafter referred to the Swedish mammography screening program. Results: After 15 years of follow-up, a higher cumulative incidence of IBTR was observed in control patients, 23.9%, versus irradiated patients, 11.5%, P < 0.001. Recurrence-free survival was inferior, 51.7% versus 60.4%, P = 0.0013. The main effect of RT was seen during the first 5 years. However, overall survival was not significantly lower 68.4% versus 71.1%, P = 0.68, nor was breast cancer specific mortality significantly higher. Conclusions: RT after BCS significantly reduced the incidence of IBTR at 15 years of followup. We were unable to identify subgroups which could be spared RT. Breast cancer mortality was not significantly reduced after RT. Good predictive markers for radiation sensitivity and improved adjuvant systeinic therapy are needed to omit RT after BCS.

    Quantitative DNA methylation analyses reveal stage dependent DNA methylation and association to clinico-pathological factors in breast tumors2013Ingår i: BMC Cancer, ISSN 1471-2407, E-ISSN 1471-2407, Vol. 13, s. 456-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Aberrant DNA methylation of regulatory genes has frequently been found in human breast cancers and correlated to clinical outcome. In the present study we investigate stage specific changes in the DNA methylation patterns in order to identify valuable markers to understand how these changes affect breast cancer progression. Methods: Quantitative DNA methylation analyses of 12 candidate genes ABCB1, BRCCA1, CDKN2A, ESR1, GSTP1, IGF2, MGMT, HMLH1, PPP2R2B, PTEN, RASSF1A and FOXC1 was performed by pyrosequencing a series of 238 breast cancer tissue samples from DCIS to invasive tumors stage I to IV. Results: Significant differences in methylation levels between the DCIS and invasive stage II tumors were observed for six genes RASSF1A, CDKN2A, MGMT, ABCB1, GSTP1 and FOXC1. RASSF1A, ABCB1 and GSTP1 showed significantly higher methylation levels in late stage compared to the early stage breast carcinoma. Z-score analysis revealed significantly lower methylation levels in DCIS and stage I tumors compared with stage II, III and IV tumors. Methylation levels of PTEN, PPP2R2B, FOXC1, ABCB1 and BRCA1 were lower in tumors harboring TP53 mutations then in tumors with wild type TP53. Z-score analysis showed that TP53 mutated tumors had significantly lower overall methylation levels compared to tumors with wild type TP53. Methylation levels of RASSF1A, PPP2R2B, GSTP1 and FOXC1 were higher in ER positive vs. ER negative tumors and methylation levels of PTEN and CDKN2A were higher in HER2 positive vs. HER2 negative tumors. Z-score analysis also showed that HER2 positive tumors had significantly higher z-scores of methylation compared to the HER2 negative tumors. Univariate survival analysis identifies methylation status of PPP2R2B as significant predictor of overall survival and breast cancer specific survival. Conclusions: In the present study we report that the level of aberrant DNA methylation is higher in late stage compared with early stage of invasive breast cancers and DCIS for genes mentioned above.

    Abstract [sv]

    En studie som nyligen publicerades i Acta Oncologica pekar på brister i rapporteringen till Cancerregistret.

    Studien visar att fall av exempelvis hjärntumörer, lymfom och leukemier inte rapporteras till Cancerregistret i samma utsträckning som bröstcancer och urologiska cancerformer. Underrapporteringen varierar med bland annat typ av vårdinrättning och patientens kön och ålder.

    A health economic evaluation of follow-up after breast cancer surgery: results of an rct study2009Ingår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 48, nr 1, s. 99-104Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    INTRODUCTION: Breast cancer follow-up programmes consume large resources and despite the indications that several alternative approaches could be used effectively, there is no coherent discussion about costs and/or cost-effectiveness of follow-up programmes. PATIENT AND METHODS: In a prospective trial there were 264 breast cancer patients, stage I and II, randomised to two different follow-up programmes- PG (physician group) and NG (nurse group). The trial period was 5 years. The women in the two intervention groups did not differ in anxiety and depression, their satisfaction with care, their experienced accessibility to the medical centre or their medical outcome as measured by recurrence or death. The analyses were done from different lists representing costs at three hospitals in Sweden according to the principles of a cost minimization study. RESULTS: The cost per person year of follow-up differed between the groups, with 630 euro per person year in PG compared to 495 euro per person year in NG. Thus, specialist nurse intervention with check-ups on demand was 20% less expensive than routine follow-up visits to the physician. The main difference in cost between the groups was explained by the numbers of visits to the physician in the respective study arms. There were 21% more primary contacts in PG than NG. DISCUSSION: The difference in cost per year and patient by study arm is modest, but transforms to nearly 900 euro per patient and 5-year period, offering a substantial opportunity for reallocating resources since breast cancer is the most prevalent tumour worldwide.

    The usefulness of a multidisciplinary educational programme after breast cancer surgery: A prospective and comparative study2006Ingår i: European Journal of Oncology Nursing, ISSN 1462-3889, E-ISSN 1532-2122, Vol. 10, nr 4, s. 273-282Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the study was to compare and evaluate a multidisciplinary educational programme with traditional follow-up visits to a physician after breast cancer surgery in terms of well-being, aspects of self-care and coping ability 1 year after diagnosis. A reduction in the intensity of follow-up after breast cancer surgery is recommended. New follow-up models are being debated and could be of interest. The study design was non-randomised and comparative. Ninety-six consecutively selected women with newly diagnosed breast cancer, classified as stage I or stage II, participated in either a multidisciplinary educational programme (n=50), or traditional follow-up by a physician (n=46). Three questionnaires were used: Functional Assessment of Cancer Therapy-General (FACT-G), a study specific questionnaire regarding self-care aspects (SCA) and Sense of Coherence (SOC). With the exception of physical well-being at baseline there was no significant difference between the groups. The women in the multidisciplinary educational programme increased their physical and functional well-being (P<0.01). The women in traditional follow-up by a physician increased their functional well-being while social/family well-being (P<0.01) decreased over time. There was a statistically significant difference in SOC (P<0.001) in the traditional follow-up by a physician between baseline (mean=74.4, SD=12.4) and the 1-year follow up (mean=67.7, SD=11.4). Thus, women in the traditional follow-up by a physician scored lower in the area of SOC 1 year after diagnosis. A multidisciplinary educational programme may be an alternative to traditional follow-up by a physician after breast cancer surgery, but more research is needed about the financial benefits and effectiveness of such a programme.

    Cyclin B is an immunohistochemical proliferation marker which can predict for breast cancer death in low-risk node negative breast cancer2010Ingår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 49, nr 6, s. 816-820Artikel i tidskrift (Refereegranskat)
    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.

    Does immediate breast reconstruction using free flaps lead to delay in the administration of adjuvant chemotherapy for breast cancer?2010Ingår i: European Journal of Surgical Oncology, ISSN 0748-7983, E-ISSN 1532-2157, Vol. 36, nr 8, s. 745-749Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a significant delay in the commencement of adjuvant treatment after mastectomy and free flap IBR in comparison to mastectomy alone patients due to reconstruction related surgical complications. The effects of this delay on survival have not been fully investigated yet and may be significant for at least some of the patients.

    Follow-up may not be beneficial after treatment of grade 1 breast cancer2009Ingår i: British Journal of Surgery, ISSN 0007-1323, E-ISSN 1365-2168, Vol. 96, nr 9, s. 999-1004Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Identification of women treated for breast cancer who have a low risk of locoregional recurrence or contralateral breast cancer, and who can be discharged safely from follow-up, would lower costs without compromising prognosis. This study investigated the risk of locoregional recurrence and contralateral breast cancer in women treated for grade 1 breast cancer. METHODS: Some 1143 women who had surgery for breast cancer were followed, and the rate of locoregional recurrence or contralateral breast cancer was determined. The risk was compared to the tumour grade. RESULTS: At a mean follow-up of 9.1 years, 10-year estimates of the cumulative risk of locoregional recurrence or contralateral breast cancer for grade 1, 2 and 3 breast cancer were 0.03 (95 per cent confidence interval (c.i.) 0.01 to 0.08), 0.12 (0.09 to 0.15) and 0.16 (0.13 to 0.20) respectively. Grade 1 tumours had a risk of locoregional recurrence or contralateral breast cancer of 285 (95 per cent c.i. 93 to 670) per 100,000 person-years. CONCLUSION: Women treated for grade 1 breast cancer could be discharged from follow-up after completion of the primary treatment, without compromising their quality of care.

    Parathyroid Klotho Expression Declines with Renal Function in Hyperparathyroid CKD PatientsManuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    Current data suggest that type I membrane-bound α-Klotho plays a dual role in the regulation of PTH secretion. While stimulating PTH release during hypocalcemia, Klotho inhibits PTH production by mediating the suppressive effect of fibroblast growth factor-23 (FGF23). In chronic kidney disease (CKD), secondary hyperparathyroidism (sHPT) often develops in the presence of high serum FGF23, indicating parathyroid resistance to FGF23 action. This could in part be due to reduced Klotho expression, as reported in kidneys of CKD patients. Herein, we analyzed parathyroid Klotho expression level in 31 patients with sHPT as well as regulation of Klotho in isolated bovine parathyroid cells using real-time PCR analysis and IHC staining. Klotho expression was variable in secondary hyperplastic glands, yet the mRNA levels correlated positively with glomerular filtration rate and significantly decreased over CKD stages. In vitro treatment with either FGF23 or calcium dose-dependently reduced the Klotho level, whereas vitamin D treatment increased its expression. This stimulatory effect was blunted in the presence of either high FGF23 or calcium. No effect on Klotho level was observed after treatment with phosphate or PTH. In summary, parathyroid Klotho expression was variable in sHPT but decreased with declining renal function. This may be due to a complex co-regulation by calcium, FGF23 and vitamin D, and explain the lack of suppressive effects of FGF23 on PTH secretion in late CKD.

    Preventive medicine of von Hippel-Lindau disease-associated pancreatic neuroendocrine tumors2018Ingår i: Endocrine-Related Cancer, ISSN 1351-0088, E-ISSN 1479-6821, Vol. 25, nr 9, s. 783-793Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Pancreatic neuroendocrine tumors (PanNETs) are rare in von Hippel-Lindau disease (VHL) but cause serious morbidity and mortality. Management guidelines for VHL-PanNETs continue to be based on limited evidence, and survival data to guide surgical management are lacking. We established the European-American-Asian-VHL-PanNET-Registry to assess data for risks for metastases, survival and long-term outcomes to provide best management recommendations. Of 2330 VHL patients, 273 had a total of 484 PanNETs. Median age at diagnosis of PanNET was 35 years (range 10-75). Fifty-five (20%) patients had metastatic PanNETs. Metastatic PanNETs were significantly larger (median size 5 vs 2 cm; P < 0.001) and tumor volume doubling time (TVDT) was faster (22 vs 126 months; P = 0.001). All metastatic tumors were >= 2.8 cm. Codons 161 and 167 were hotspots for VHL germline mutations with enhanced risk for metastatic PanNETs. Multivariate prediction modeling disclosed maximum tumor diameter and TVDT as significant predictors for metastatic disease (positive and negative predictive values of 51% and 100% for diameter cut-off >= 2.8 cm, 44% and 91% for TVDT cut-off of <= 24 months). In 117 of 273 patients, PanNETs > 1.5 cm in diameter were operated. Ten-year survival was significantly longer in operated vs non-operated patients, in particular for PanNETs < 2.8 cm vs >= 2.8 cm (94% vs 85% by 10 years; P = 0.020; 80% vs 50% at 10 years; P = 0.030). This study demonstrates that patients with PanNET approaching the cut-off diameter of 2.8 cm should be operated. Mutations in exon 3, especially of codons 161/167 are at enhanced risk for metastatic PanNETs. Survival is significantly longer in operated non-metastatic VHL-PanNETs.

    Integrated molecular profiles of invasive breast tumors and ductal carcinoma in situ (DCIS) reveal differential vascular and interleukin signaling2012Ingår i: Proceedings of the National Academy of Sciences of the United States of America, ISSN 0027-8424, E-ISSN 1091-6490, Vol. 109, nr 8, s. 2802-2807Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We use an integrated approach to understand breast cancer heterogeneity by modeling mRNA, copy number alterations, microRNAs, and methylation in a pathway context utilizing the pathway recognition algorithm using data integration on genomic models (PARADIGM). We demonstrate that combining mRNA expression and DNA copy number classified the patients in groups that provide the best predictive value with respect to prognosis and identified key molecular and stromal signatures. A chronic inflammatory signature, which promotes the development and/or progression of various epithelial tumors, is uniformly present in all breast cancers. We further demonstrate that within the adaptive immune lineage, the strongest predictor of good outcome is the acquisition of a gene signature that favors a high T-helper 1 (Th1)/cytotoxic T-lymphocyte response at the expense of Th2-driven humoral immunity. Patients who have breast cancer with a basal HER2-negative molecular profile (PDGM2) are characterized by high expression of protumorigenic Th2/humoral-related genes (24-38%) and a low Th1/Th2 ratio. The luminal molecular subtypes are again differentiated by low or high FOXM1 and ERBB4 signaling. We show that the interleukin signaling profiles observed in invasive cancers are absent or weakly expressed in healthy tissue but already prominent in ductal carcinoma in situ, together with ECM and cell-cell adhesion regulating pathways. The most prominent difference between low and high mammographic density in healthy breast tissue by PARADIGM was that of STAT4 signaling. In conclusion, by means of a pathway-based modeling methodology (PARADIGM) integrating different layers of molecular data from whole-tumor samples, we demonstrate that we can stratify immune signatures that predict patient survival.

    The impact of CPR and AED training on healthcare professionals' self-perceived attitudes to performing resuscitation2012Ingår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, E-ISSN 1757-7241, Vol. 20, s. 26-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Healthcare professionals have shown concern about performing mouth-to-mouth ventilation due to the risks to themselves with the procedure. However, little is known about healthcare professionals' fears and attitudes to start CPR and the impact of training. Objective: To examine whether there were any changes in the attitudes among healthcare professionals to performing CPR from before to after training. Methods: Healthcare professionals from two Swedish hospitals were asked to answer a questionnaire before and after training. The questions were relating to physical and mental discomfort and attitudes to CPR. Statistical analysis used was generalized McNemar's test. Results: Overall, there was significant improvement in 10 of 11 items, reflecting various aspects of attitudes to CPR. All groups of health care professionals (physicians, nurses, assistant nurses, and "others" = physiotherapists, occupational therapists, social welfare officers, psychologists, biomedical analysts) felt more secure in CPR knowledge after education. In other aspects, such as anxiety prior to a possible cardiac arrest, only nurses and assistant nurses improved. The concern about being infected, when performing mouth to mouth ventilation, was reduced with the most marked reduction in physicians (75%; P < 0.001). Conclusion: In this hospital-based setting, we found a positive outcome of education and training in CPR concerning healthcare professionals' attitudes to perform CPR. They felt more secure in their knowledge of cardiopulmonary resuscitation. In some aspects of attitudes to resuscitation nurses and assistant nurses appeared to be the groups that were most markedly influenced. The concern of being infected by a disease was low.

    Value of Tumor Growth Rate (TGR) as an Early Biomarker Predictor of Patients' Outcome in Neuroendocrine Tumors (NET): The GREPONET Study2019Ingår i: The Oncologist, ISSN 1083-7159, E-ISSN 1549-490X, Vol. 24, nr 11, s. E1082-E1090Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    INTRODUCTION: Tumor growth rate (TGR; percent size change per month [%/m]) is postulated to be an early radiological biomarker to overcome limitations of RECIST. This study aimed to assess the impact of TGR in neuroendocrine tumors (NETs) and potential clinical and therapeutic applications.

    MATERIALS AND METHODS: Patients (pts) with advanced grade (G) 1/2 NETs from the pancreas or small bowel initiating systemic treatment (ST) or watch and wait (WW) were eligible. Baseline and follow-up scans were retrospectively reviewed to calculate TGR at pretreatment (TGR0), first follow-up (TGRfirst), and 3(±1) months of study entry (TGR3m).

    RESULTS: Out of 905 pts screened, 222 were eligible. Best TGRfirst (222 pts) cutoff was 0.8 (area under the curve, 0.74). When applied to TGR3m (103 pts), pts with TGR3m <0.8 (66.9%) versus TGR3m ≥ 0.8 (33.1%) had longer median progression-free survival (PFS; 26.3 m; 95% confidence interval [CI] 19.5-32.4 vs. 9.3 m; 95% CI, 6.1-22.9) and lower progression rate at 12 months (7.3% vs. 56.8%; p = .001). WW (vs. ST) and TGR3m ≥ 0.8 (hazard ratio [HR], 3.75; 95% CI, 2.21-6.34; p < .001) were retained as factors associated with a shorter PFS in multivariable Cox regression. TGR3m (HR, 3.62; 95% CI, 1.97-6.64; p < .001) was also an independent factor related to shorter PFS when analysis was limited to pts with stable disease (81 pts). Out of the 60 pts with TGR0 data available, 60% of pts had TGR0 < 4%/month. TGR0 ≥ 4 %/month (HR, 2.22; 95% CI, 1.15-4.31; p = .018) was also an independent factor related to shorter PFS.

    CONCLUSION: TGR is an early radiological biomarker able to predict PFS and to identify patients with advanced NETs who may require closer radiological follow-up.

    IMPLICATIONS FOR PRACTICE: Tumor growth rate at 3 months (TGR3m) is an early radiological biomarker able to predict progression-free survival and to identify patients with advanced neuroendocrine tumors who may require closer radiological follow-up. It is feasible to calculate TGR3m in clinical practice and it could be a useful tool for guiding patient management. This biomarker could also be implemented in future clinical trials to assess response to therapy.

    Quantifying differences in breast cancer survival between England and Norway2011Ingår i: Cancer Epidemiology, ISSN 1877-7821, E-ISSN 1877-783X, Vol. 35, nr 6, s. 526-533Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    Survival from breast cancer is lower in the UK than in some other European countries. We compared survival in England and Norway by age and time from diagnosis.

    METHODS:

    We included 303,648 English and 24,919 Norwegian cases of breast cancer diagnosed 1996-2004 using flexible parametric relative survival models, enabling improved quantification of differences in survival. Crude probabilities were estimated to partition the probability of death due to all causes into that due to cancer and other causes and to estimate the number of "avoidable" deaths.

    RESULTS:

    England had lower relative survival for all ages with the difference increasing with age. Much of the difference was due to higher excess mortality in England in the first few months after diagnosis. Older patients had a higher proportion of deaths due to other causes. At 5 years post diagnosis, a woman aged 85 in England had probabilities of 0.35 of dying of cancer and 0.32 of dying of other causes, whilst in Norway they were 0.26 and 0.35. By eight years the number of "avoidable" all-cause deaths in England was 1020 with the number of "avoidable" breast cancer related deaths 1488.

    CONCLUSION:

    Lower breast cancer survival in England is mainly due to higher mortality in the first year after diagnosis. Crude probabilities aid our understanding of the impact of disease on individual patients and help assess different treatment options.

    Focused image-guided parathyroidectomy in the current management of primary hyperparathyroidism.2015Ingår i: Archives of Disease in Childhood, ISSN 0003-9888, E-ISSN 1468-2044, Vol. 100, nr 10Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: Primary hyperparathyroidism (PHPT) in childhood and adolescence has been considered a different disease to that seen in adults, with predominantly familial aetiology mandating open exploration to exclude parathyroid hyperplasia in contrast to the adoption of focused image-guided parathyroidectomy (FP) in adults.

    STUDY DESIGN: A retrospective cohort study in a tertiary referral hospital setting of all children and adolescents (<18 years) undergoing parathyroid surgery for PHPT. Data were obtained from a dedicated endocrine surgery database and hospital medical records.

    RESULTS: Over the 35-year study period (1980-2014), there were 31 patients who underwent parathyroidectomy for PHPT. 3 patients were from known multiple endocrine neoplasia type 1 syndrome (MEN1) families, 3 had an isolated family history of PHPT and 25 were sporadic. In the sporadic group, 24 (96%) presented with symptomatic hypercalcaemia, affecting the gastrointestinal, musculoskeletal, genitourinary or neuropsychiatric systems. In the 25 patients with sporadic PHPT, nine (36%) had FP with a single adenoma removed with a 100% initial cure rate. Sixteen patients (64%) in the sporadic group had an open exploration: 14 had single gland disease while 2 patients required a second procedure to achieve a final cure rate of 100%. Of the three patients with MEN1, one was cured, one has persistent hyperparathyroidism after FP and the third has permanent hypoparathyroidism after open exploration.

    CONCLUSIONS: The majority of children and adolescents with PHPT have symptomatic disease due to a single adenoma. They can therefore be managed in a similar fashion to their adult counterparts with preoperative localisation studies aiming to permit FP in a day case setting.

    Red meat consumption and risk of cancers of the proximal colon, distal colon and rectum: the Swedish Mammography Cohort2005Ingår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 113, nr 5, s. 829-34Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Although there is considerable evidence that high consumption of red meat may increase the risk of colorectal cancer, data by subsite within the colon are sparse. The objective of our study was to prospectively examine whether the association of red meat consumption with cancer risk varies by subsite within the large bowel. We analyzed data from the Swedish Mammography Cohort of 61,433 women aged 40-75 years and free from diagnosed cancer at baseline in 1987-1990. Diet was assessed at baseline using a self-administered food-frequency questionnaire. Over a mean follow-up of 13.9 years, we identified 234 proximal colon cancers, 155 distal colon cancers and 230 rectal cancers. We observed a significant positive association between red meat consumption and risk of distal colon cancer (p for trend = 0.001) but not of cancers of the proximal colon (p for trend = 0.95) or rectum (p for trend = 0.32). The multivariate rate ratio for women who consumed 94 or more g/day of red meat compared to those who consumed less than 50 g/day was 2.22 (95% confidence interval [CI] 1.34-3.68) for distal colon, 1.03 (95% CI 0.67-1.60) for proximal colon and 1.28 (95% CI 0.83-1.98) for rectum. Although there was no association between consumption of fish and risk of cancer at any subsite, poultry consumption was weakly inversely related to risk of total colorectal cancer (p for trend = 0.04). These findings suggest that high consumption of red meat may substantially increase the risk of distal colon cancer. Future investigations on red meat and colorectal cancer risk should consider cancer subsites separately.

    Gene expression modules in primary breast cancers as risk factors for organotropic patterns of first metastatic spread: a case control study2017Ingår i: Breast Cancer Research, ISSN 1465-5411, E-ISSN 1465-542X, Vol. 19, artikel-id 113Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Metastases from primary breast cancers can involve single or multiple organs at metastatic disease diagnosis. Molecular risk factors for particular patterns of metastastic spread in a clinical population are limited.

    Methods: A case-control design including 1357 primary breast cancers was used to study three distinct clinical patterns of metastasis, which occur within the first six months of metastatic disease: bone and visceral metasynchronous spread, bone-only, and visceral-only metastasis. Whole-genome expression profiles were obtained using whole genome (WG)-DASL assays from formalin-fixed paraffin-embedded (FFPE) samples. A systematic protocol was developed for handling FFPE samples together with stringent data quality controls to identify robust expression profiling data. A panel of published and novel gene sets were tested for association with these specific patterns of metastatic spread and odds ratios (ORs) were calculated.

    Results: Metasynchronous metastasis to bone and viscera was found in all intrinsic breast cancer subtypes, while immunohistochemically (IHC)-defined receptor status and specific IntClust subgroups were risk factors for visceral-only or bone-only first metastases. Among gene modules, those related to proliferation increased the risk of metasynchronous metastasis (OR (95% CI) = 2.3 (1.1-4.8)) and visceral-only first metastasis (OR (95% CI) = 2.5 (1.2-5.1)) but not bone-only metastasis (OR (95% CI) = 0.97 (0.56-1.7)). A 21-gene module (BV) was identified in estrogen-receptor-positive breast cancers with metasynchronous metastasis to bone and viscera (area under the curve = 0.77), and its expression increased the risk of bone and visceral metasynchronous spread in this population. BV was further orthogonally validated with NanoString nCounter in primary breast cancers, and was reproducible in their matched lymph nodes metastases and an external cohort.

    Conclusion: This case-control study of WG-DASL global expression profiles from FFPE tumour samples, after careful quality control and RNA selection, revealed that gene modules in the primary tumour have differing risks for clinical patterns of metasynchronous first metastases. Moreover, a novel gene module was identified as a putative risk factor for metasynchronous bone and visceral first metastatic spread, with potential implications for disease monitoring and treatment planning.

    Double-detargeted oncolytic adenovirus shows replication arrest in liver cells and retains neuroendocrine cell killing ability2010Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 5, nr 1, s. e8916-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    We have previously developed an oncolytic serotype 5 adenovirus (Ad5) with chromogranin-A (CgA) promoter-controlled E1A expression, Ad[CgA-E1A], with the intention to treat neuroendocrine tumors, including carcinoids. Since carcinoids tend to metastasize to the liver it is important to fully repress viral replication in hepatocytes to avoid adenovirus-related liver toxicity. Herein, we explore miRNA-based regulation of E1A expression as a complementary mechanism to promoter-based transcriptional control.

    METHODOLOGY/PRINCIPAL FINDINGS:

    Ad[CgA-E1A-miR122], where E1A expression is further controlled by six tandem repeats of the target sequence for the liver-specific miR122, was constructed and compared to Ad[CgA-E1A]. We observed E1A suppression and replication arrest of the miR122-detargeted adenovirus in normal hepatocytes, while the two viruses killed carcinoid cells to the same degree. Repeated intravenous injections of Ad[CgA-E1A] induced liver toxicity in mice while Ad[CgA-E1A-miR122] injections did not. Furthermore, a miR122-detargeted adenovirus with the wild-type E1A promoter showed reduced replication in hepatic cells compared to wild-type Ad5 but not to the same extent as the miR122-detargeted adenovirus with the neuroendocrine-selective CgA promoter.

    CONCLUSIONS/SIGNIFICANCE:

    A combination of transcriptional (promoter) and post-transcriptional (miRNA target) regulation to control virus replication may allow for the use of higher doses of adenovirus for efficient tumors treatment without liver toxicity.

    Oncolytic adenovirus modified with somatostatin motifs for selective infection of neuroendocrine tumor cells2011Ingår i: Gene Therapy, ISSN 0969-7128, E-ISSN 1476-5462, Vol. 18, nr 11, s. 1052-1062Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We have previously described the oncolytic adenovirus, Ad(CgA-E1A-miR122), herein denoted Ad5(CgA-E1A-miR122) that selectively replicates in and kills neuroendocrine cells, including freshly isolated midgut carcinoid cells from liver metastases. Ad5(CgA-E1A-miR122) is based on human adenovirus serotype 5 (Ad5) and infects target cells by binding to the coxsackie-adenovirus receptor (CAR) and integrins on the cell surface. Some neuroendocrine tumor (NET) and neuroblastoma cells express low levels of CAR and are therefore poorly transduced by Ad5. However, they often express high levels of somatostatin receptors (SSTRs). Therefore, we introduced cyclic peptides, which contain four amino acids (FWKT) and mimic the binding site for SSTRs in the virus fiber knob. We show that FWKT-modified Ad5 binds to SSTR2 on NET cells and transduces midgut carcinoid cells from liver metastases about 3-4 times better than non-modified Ad5 while it transduces normal hepatocytes at about 50% of Ad5. Moreover, FWKT-modified Ad5 overcomes neutralization in an ex vivo human blood loop model to greater extent than Ad5, indicating that fiber knob modification may prolong the systematic circulation time. We conclude that modification of adenovirus with the FWKT motif may be beneficial for NET therapy.

    Accelerated Proliferation and Differential Global Gene Expression in Pancreatic Islets of Five-Week-Old Heterozygous Men1 Mice: Men1 Is a Haploinsufficient Suppressor2012Ingår i: Endocrinology, ISSN 0013-7227, E-ISSN 1945-7170, Vol. 153, nr 6, s. 2588-2598Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Individuals carrying heterozygous (hz) MEN1 (Multiple Endocrine Neoplasia Syndrome Type 1) germ line mutations develop endocrine tumors as a result of somatic loss of the wild-type (wt) allele. However, endocrine cell proliferation has been observed despite wt allele retention, indicating haploinsufficiency. To study downstream molecular effects of the hz haplotype, a germ line Men1 hz mouse model was used to explore differences in global endocrine pancreatic gene expression. Because islet cells of 5-wk-old hz mice express Menin from the retained wt Men1 allele, these were isolated after collagenase digestion of the pancreas, and used for global gene expression array. Wild-type littermates were used for comparison. Array findings were corroborated by quantitative PCR, Western blotting, in situ proximity ligation assay, and immunohistochemistry. The hz islets show increased proliferation: the Ki-67 index was twice as high as in wt islets (3.48 vs. 1.74%; P = 0.024). The microarray results demonstrated that several genes were differentially expressed. Some selected genes were studied on the protein level, e.g. the cytoskeletal regulator myristoylated alanine-rich protein kinase C substrate (Marcks) was significantly less expressed in hz islets, using in situ proximity ligation assay and Western blotting (P < 0.001 and P < 0.01, respectively). Further, gene ontology analysis showed that genes with higher mRNA expression in the hz endocrine pancreas were associated with e.g. chromatin maintenance and apoptosis. Lower mRNA was observed for genes involved in growth factor binding. In conclusion, despite retained Menin expression, proliferation was accelerated, and numerous genes were differentially expressed in the endocrine pancreas of 5-wk-old hz Men1 mice, corroborating the hypothesis that MEN1 is a haploinsufficient suppressor.

    Neurogenin 3 and neurogenic differentiation 1 are retained in the cytoplasm of multiple endocrine neoplasia type 1 islet and pancreatic endocrine tumor cells2009Ingår i: Pancreas, ISSN 0885-3177, E-ISSN 1536-4828, Vol. 38, nr 3, s. 259-266Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES:

    To investigate if transcription factors involved in pancreatic differentiation and regeneration are present in pancreatic endocrine tumors and if they are differentially expressed in normal pancreas compared with multiple endocrine neoplasia type 1 (MEN1) nontumorous pancreas.

    METHODS:

    The expression of neurogenin 3 (NEUROG3), neurogenic differentiation 1 (NEUROD1), POU class 3 homeobox 4 (POU3F4), pancreatic duodenal homeobox factor 1 (PDX1), ribosomal protein L10 (RPL10), delta-like 1 homolog (Drosophila; DLK1), and menin was analyzed by immunohistochemistry in normal pancreas and pancreatic endocrine tumors from 6 patients with MEN1 and 16 patients with sporadic tumors, as well as pancreatic specimens from Men1 heterozygous and wild type mice. Quantitative polymerase chain reaction was performed in a subset of human tumors.

    RESULTS:

    Tumors and MEN1 nontumorous endocrine cells showed a prominent cytoplasmatic NEUROG3 and NEUROD1 expression. These factors were significantly more expressed in the cytoplasm of Men1 heterozygous mouse islet cells compared with wild type islets; the latter showed an exclusively nuclear reactivity. The degree of Pou3f4, Rpl10, and Dlk1 immunoreactivities differed significantly between islets of heterozygous and wild type mice. The expressions of RPL10 and NEUROD1 were prominent in the MEN1 human and heterozygous mouse exocrine pancreas. Insulinomas had significantly higher PDX1 and DLK1 messenger RNA levels compared with other tumor types.

    CONCLUSIONS:

    Transcription factors involved in pancreatic development show altered expression and subcellular localization in MEN1 nontumorous pancreas and pancreatic endocrine tumors.

    Molecular Features of Subtype-Specific Progression from Ductal Carcinoma In Situ to Invasive Breast Cancer2016Ingår i: Cell reports, ISSN 2211-1247, E-ISSN 2211-1247, Vol. 16, nr 4, s. 1166-1179Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Breast cancer consists of at least five main molecular "intrinsic'' subtypes that are reflected in both pre-invasive and invasive disease. Although previous studies have suggested that many of the molecular features of invasive breast cancer are established early, it is unclear what mechanisms drive progression and whether the mechanisms of progression are dependent or independent of subtype. We have generated mRNA, miRNA, and DNA copy-number profiles from a total of 59 in situ lesions and 85 invasive tumors in order to comprehensively identify those genes, signaling pathways, processes, and cell types that are involved in breast cancer progression. Our work provides evidence that there are molecular features associated with disease progression that are unique to the intrinsic subtypes. We additionally establish subtype-specific signatures that are able to identify a small proportion of pre-invasive tumors with expression profiles that resemble invasive carcinoma, indicating a higher likelihood of future disease progression.

    Genome-wide Scan Identifies Role for AOX1 in Prostate Cancer Survival2018Ingår i: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 74, nr 6, s. 710-719Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Most men diagnosed with prostate cancer have low-risk cancers. How to predict prostate cancer progression at the time of diagnosis remains challenging. Objective: To identify single nucleotide polymorphisms (SNPs) associated with death from prostate cancer. Design, setting, and participants: Blood samples from 11 506 men in Sweden were collected during 1991-1996. Of these, 1053 men were diagnosed with prostate cancer and 245 died from the disease. Stage and grade at diagnosis and outcome information were obtained, and DNA from all cases was genotyped. Outcome measurements and statistical analysis: A total of 6 126 633 SNPs were tested for association with prostate-cancer-specific survival time using a Cox proportional hazard model, adjusted for age, stage, and grade at diagnosis. A value of 1 x 10(-6) was used as suggestive significance threshold. Positive candidate SNPs were tested for association with gene expression using expression quantitative trait locus analysis. Results and limitations: We found 12 SNPs at seven independent loci associated with prostate-cancerspecific survival time. One of 6 126 633 SNPs tested reached genome-wide significance (p < 5 x 10(-8)) and replicated in an independent cohort: rs73055188 (p = 5.27 x 10(-9), per-allele hazard ratio [HR] = 2.27, 95% confidence interval [CI] 1.72-2.98) in the AOX1 gene. A second SNP reached a suggestive level of significance (p <1 x 10(-6)) and replicated in an independent cohort: rs2702185 (p = 7.1 x 10(-7), per-allele HR = 2.55, 95% CI = 1.76-3.69) in the SMG7 gene. The SNP rs73055188 is correlated with AOX1 expression levels, which is associated with biochemical recurrence of prostate cancer in independent cohorts. This association is yet to be validated in other ethnic groups. Conclusions: The SNP rs73055188 at the AOX1 locus is associated with prostate-cancer-specific survival time, and AOX1 gene expression level is correlated with biochemical recurrence of prostate cancer. Patient summary: We identify two genetic markers that are associated with prostate-cancer-specific survival time.

    Period-specific mean annual hospital volume of radical cystectomy is associated with outcome and perioperative quality of care: a nationwide population-based study2019Ingår i: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 124, nr 3, s. 449-456Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective

    To investigate the association between hospital volume and overall survival (OS), cancer‐specific survival (CSS), and quality of care of patients with bladder cancer who undergo radical cystectomy (RC), defined as the use of extended lymphadenectomy (eLND), continent reconstruction, neoadjuvant chemotherapy (NAC), and treatment delay of <3 months.

    Patients and Methods

    We used the Bladder Cancer Data Base Sweden (BladderBaSe) to study survival and indicators of perioperative quality of care in all 3172 patients who underwent RC for primary invasive bladder cancer stage T1–T3 in Sweden between 1997 and 2014. The period‐specific mean annual hospital volume (PSMAV) during the 3 years preceding surgery was applied as an exposure and analysed using univariate and multivariate mixed models, adjusting for tumour and nodal stage, age, gender, comorbidity, educational level, and NAC. PSMAV was either categorised in tertiles, dichotomised (at ≥25 RCs annually), or used as a continuous variable for every increase of 10 RCs annually.

    Results

    PSMAV in the highest tertile (≥25 RCs annually) was associated with improved OS (hazard ratio [HR] 0.87, 95% confidence interval [CI] 0.75–1.0), whereas the corresponding HR for CSS was 0.87 (95% CI 0.73–1.04). With PSMAV as a continuous variable, OS was improved for every increase of 10 RCs annually (HR 0.95, 95% CI 0.90–0.99). Moreover, higher PSMAV was associated with increased use of eLND, continent reconstruction and NAC, but also more frequently with a treatment delay of >3 months after diagnosis.

    Conclusions

    The current study supports centralisation of RC for bladder cancer, but also underpins the need for monitoring treatment delays associated with referral.

    A prospective stepped wedge cohort evaluation of the new national trauma team activation criteria in Sweden - the TRAUMALERT study.2019Ingår i: Scandinavian Journal of Trauma, Resuscitation and Emergency Medicine, ISSN 1757-7241, E-ISSN 1757-7241, Vol. 27, nr 1, artikel-id 52Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Trauma triage based on prehospital information facilitates correct allocation of in-hospital resources. The Swedish national two-tier trauma team activation (TTA) criteria were revised in 2016. The current study aimed to evaluate the safety and efficacy of the new criteria.

    METHODS: Five centres covering trauma care for 1.2 million inhabitants registered all trauma patients prospectively in the Swedish trauma registry (SweTrau) prior to and after stepwise introduction of new TTA criteria within the cohort (a prospective stepped-wedge cohort study design; period August 2016-November 2017). Evaluation of full- and limited-TTA frequency, under- and overtriage were performed at equal duration before and after this change.

    RESULTS: The centres registered 1948 patients, 1882 (96.6%) of which were included in the study. With new criteria, frequency of full-TTA was unchanged, while limited-TTA decreased with 46.3% (from 988 to 531). 30-day trauma mortality was unchanged. The overtriage was 107/150 (71.3%) with former criteria, and 104/144 (72.2%) with new criteria, p = 0.866. Undertriage was 50/1037 (4.8%) versus 39/551 (7.1%), p = 0.063. Undertriage was consistently > 20% in patients with fall injury. Among patients with Injury Severity Score (ISS) > 15, 50/93 (53.8%) did not initiate full-TTA with former, vs 39/79 (49.4%) with new criteria, p = 0.565. Age > 60-years was a risk factor for undertriage (OR 2.89, p < 0.001), while low fall injuries indicated a trend (OR 2.70, p = 0.051).

    CONCLUSIONS: The newly implemented Swedish TTA criteria result in a reduction in limited TTA frequency, indicating an increased efficiency in use of resources. The over- and undertriage is unchanged compared to former criteria, thus upholding patient safety.

    Genomic copy number imbalances associated with bone and non-bone metastasis of early-stage breast cancer2014Ingår i: Breast Cancer Research and Treatment, ISSN 0167-6806, E-ISSN 1573-7217, Vol. 143, nr 1, s. 189-201Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of this study is to identify and validate copy number aberrations in early-stage primary breast tumors associated with bone or non-bone metastasis. Whole-genome molecular inversion probe arrays were used to evaluate copy number imbalances (CNIs) in breast tumors from 960 early-stage patients with information about site of metastasis. The CoxBoost algorithm was used to select metastasis site-related CNIs and to fit a Cox proportional hazards model. Gains at 1q41 and 1q42.12 and losses at 1p13.3, 8p22, and Xp11.3 were significantly associated with bone metastasis. Gains at 2p11.2, 3q21.3-22.2, 3q27.1, 10q23.1, and 14q13.2-3 and loss at 7q21.11 were associated with non-bone metastasis. To examine the joint effect of CNIs and clinical predictors, patients were stratified into three risk groups (low, intermediate, and high) based on the sum of predicted linear hazard ratios. For bone metastasis, the hazard (95 % confidence interval) for the low-risk group was 0.32 (0.11-0.92) compared to the intermediate-risk group and 2.99 (1.74-5.11) for the high-risk group. For non-bone metastasis, the hazard for the low-risk group was 0.34 (0.17-0.66) and 2.33 (1.59-3.43) for the high-risk group. The prognostic value of loss at 8p22 for bone metastasis and gains at 10q23.1 for non-bone metastasis, and gain at 11q13.5 for both bone and non-bone metastases were externally validated in 335 breast tumors pooled from four independent cohorts. Distinct CNIs are independently associated with bone and non-bone metastasis for early-stage breast cancer patients across cohorts. These data warrant consideration for tailoring surveillance and management of metastasis risk.

    Nerve stimulation in thyroid surgery: is it really useful?2007Ingår i: ANZ journal of surgery, ISSN 1445-1433, E-ISSN 1445-2197, Vol. 77, nr 5, s. 377-380Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Monitoring of the recurrent laryngeal nerve (RLN) has been claimed in some studies to reduce rates of nerve injury during thyroid surgery compared with anatomical dissection and visual identification of the RLN alone, whereas other studies have found no benefit. Continuous monitoring with endotracheal electrodes is expensive whereas discontinuous monitoring by laryngeal palpation with nerve stimulation is a simple and inexpensive technique. This study aimed to assess the value of nerve stimulation with laryngeal palpation as a means of identifying and assessing the function of the RLN and external branch of the superior laryngeal nerve (EBSLN) during thyroid surgery. METHODS: This was a prospective case series comprising 50 consecutive patients undergoing total thyroidectomy providing 100 RLN and 100 EBSLN for examination. All patients underwent preoperative and postoperative vocal cord and voice assessment by an independent ear, nose and throat surgeon, laryngeal examination at extubation and all were asked to complete a postoperative dysphagia score sheet. Dysphagia scores in the study group were compared with a control group (n = 20) undergoing total thyroidectomy without nerve stimulation. RESULTS: One hundred of 100 (100%) RLN were located without the use of the nerve stimulator. A negative twitch response occurred in seven (7%) RLN stimulated (two bilateral, three unilateral). Postoperative testing, however, only showed one true unilateral RLN palsy postoperatively (1%), which recovered in 7 weeks giving six false-positive and one true-positive results. Eighty-six of 100 (86%) EBSLN were located without the nerve stimulator. Thirteen of 100 (13%) EBSLN could not be identified and 1 of 100 (1%) was located with the use of the nerve stimulator. Fourteen per cent of EBSLN showed no cricothyroid twitch on EBSLN stimulation. Postoperative vocal function in these patients was normal. There were no instances of equipment malfunction. Dysphagia scores did not differ significantly between the study and control groups. CONCLUSION: Use of a nerve stimulator did not aid in anatomical dissection of the RLN and was useful in identifying only one EBSLN. Discontinuous nerve monitoring by stimulation during total thyroidectomy confers no obvious benefit for the experienced surgeon in nerve identification, functional testing or injury prevention.

    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 cancer2013Ingår i: Cancer Letters, ISSN 0304-3835, E-ISSN 1872-7980, Vol. 333, nr 2, s. 222-228Artikel i tidskrift (Refereegranskat)
    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.

    Differentially regulated genes in MEN1-transfected BON cells using RT-differential display and oligonucleotide microarrays2009Ingår i: Anticancer Research, ISSN 0250-7005, E-ISSN 1791-7530, Vol. 29, nr 6, s. 1859-1866Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND:

    Apart from inactivation of the MEN1 gene, the molecular mechanisms involved in tumorigenesis of the endocrine organs and MEN1-associated non-endocrine lesions remain unknown.

    MATERIALS AND METHODS:

    In order to learn more about down-stream effects upon MEN1 gene inactivation BON1 cells were transfected with a MEN1 gene construct (BON/M1C), and both RT-differential display and oligonucleotide microarrays were performed.

    RESULTS:

    Three genes (SMARCC1, OVCA2 and SRp55) found to be differentially regulated on differential display were corroborated by northern blots on cell line RNA when comparing MEN1 transfected cells with control (empty vector transfection). When comparing two different passages of BON/M1C with two passages of vector control using oligonucleotide microarrays, 25 up-regulated genes and 64 down-regulated genes could be found using a cut-off of >or=1.6 times.

    CONCLUSION:

    These findings might contribute to the understanding of the molecular pathways involved in MEN1 tumorigenesis, and may also provide knowledge of genes involved in sporadic endocrine tumorigenesis.

    Expression and association of TRPC subtypes with Orai1 and STIM1 in human parathyroid2010Ingår i: Journal of Molecular Endocrinology, ISSN 0952-5041, E-ISSN 1479-6813, Vol. 44, nr 5, s. 285-294Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The mechanism behind Ca2+ entry into the parathyroid cells has been widely debated, and the molecular identities of the responsible ion channels have not been established yet. In this study, we show that the parathyroid cells lack voltage-operated Ca2+ channels. Passive store depletion by thapsigargin, on the other hand, induces a large non-voltage-activated non-selective cation current. The increase in intracellular Ca2+ caused by thapsigargin is attenuated by 2-aminoethoxydiphenyl borate, a blocker of store-operated Ca2+ entry (SOCE). Candidate molecules for non-voltage-operated Ca2+ signaling were investigated. These included members of the transient receptor potential canonical (TRPC) ion channel family, as well as Ca2+ release-activated Ca2+ modulator 1 (Orai1) and stromal interaction molecule 1 (STIM1) that are key proteins in the SOCE pathway. Using RT-PCR screening, quantitative real-time PCR, and western blot, we showed expression of TRPC1, TRPC4, and TRPC6; Orai1; and STIM1 genes and proteins in normal and adenomatous human parathyroid tissues. Furthermore, co-immunoprecipitation experiments demonstrated a ternary complex of TRPC1-Orai1-STIM1, supporting a physical interaction between these molecules in human parathyroid.

    Cyclin E1 is a strong prognostic marker for death from lymph node negative breast cancer: A population-based case-control study2015Ingår i: Acta Oncologica, ISSN 0284-186X, E-ISSN 1651-226X, Vol. 54, nr 4, s. 538-544Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background. A large proportion of women with lymph node negative breast cancer treated with systemic adjuvant treatment do not benefit from such therapy since the patient is already cured by local treatment. Several studies have suggested that proliferation markers are strong prognostic factors in early breast cancer. Cyclins are probably the most specific markers of cell proliferation. Previously high expression of cyclin E has been associated with breast cancer recurrence.

    Materials and methods. In this study we investigate the prognostic value of cyclin E1 in node negative breast cancer patients. In a population-based cohort 186 women who died from breast cancer were defined as cases and 186 women alive at the corresponding time as controls. Inclusion criteria were tumour size ≤ 50 mm, no lymph node metastases and no adjuvant chemotherapy. The study was designed to detect an odds ratio of 2.5 with a power of 90% and significance level of 0.05. Cyclin E1 was determined with immunohistochemistry (IHC) on tissue microarray (TMA).

    Results. High expression of cyclin E1 was significantly associated with breast cancer death, in both uni- and multivariate analyses with odds ratios (OR) 2.3 [univariate, 95% confidence interval (CI) 1.5-3.6] and 2.1 (multivariate, 95% CI 1.2-3.5).

    Discussion. Cyclin E1 is a strong prognostic factor for breast cancer death in a population-based and node negative patient cohort and can identify high-risk patients in this group.
