    Impact of type of reduced-intensity conditioning regimen on the outcomes of allogeneic haematopoietic cell transplantation in classical Hodgkin lymphoma2020In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 190, no 4, p. 573-582Article in journal (Refereed)
    Abstract [en]

    Reduced-intensity conditioning (RIC) allogeneic haematopoietic cell transplantation (allo-HCT) is a curative option for select relapsed/refractory Hodgkin lymphoma (HL) patients; however, there are sparse data to support superiority of any particular conditioning regimen. We analyzed 492 adult patients undergoing human leucocyte antigen (HLA)-matched sibling or unrelated donor allo-HCT for HL between 2008 and 2016, utilizing RIC with either fludarabine/busulfan (Flu/Bu), fludarabine/melphalan (Flu/Mel140) or fludarabine/cyclophosphamide (Flu/Cy). Multivariable regression analysis was performed using a significance level of <0 center dot 01. There were no significant differences between regimens in risk for non-relapse mortality (NRM) (P = 0 center dot 54), relapse/progression (P = 0 center dot 02) or progression-free survival (PFS) (P = 0 center dot 14). Flu/Cy conditioning was associated with decreased risk of mortality in the first 11 months after allo-HCT (HR = 0 center dot 28; 95% CI = 0 center dot 10-0 center dot 73; P = 0 center dot 009), but beyond 11 months post allo-HCT it was associated with a significantly higher risk of mortality, (HR = 2 center dot 46; 95% CI = 0 center dot 1.32-4 center dot 61; P = 0 center dot 005). Four-year adjusted overall survival (OS) was similar across regimens at 62% for Flu/Bu, 59% for Flu/Mel140 and 55% for Flu/Cy (P = 0 center dot 64), respectively. These data confirm the choice of RIC for allo-HCT in HL does not influence risk of relapse, NRM or PFS. Although no OS benefit was seen between Flu/Bu and Flu/Mel 140; Flu/Cy was associated with a significantly higher risk of mortality beyond 11 months from allo-HCT (possibly due to late NRM events).

    Anti-leukaemic effects induced by APR-246 are dependent on induction of oxidative stress and the NFE2L2/HMOX1 axis that can be targeted by PI3K and mTOR inhibitors in acute myeloid leukaemia cells2016In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 174, no 1, p. 117-126Article in journal (Refereed)
    Abstract [en]

    The small molecule APR-246 (PRIMA-1(MET)) is a novel drug that restores the activity of mutated and unfolded TP53 protein. However, the mechanisms of action and potential off-target effects are not fully understood. Gene expression profiling in TP53 mutant KMB3 acute myeloid leukaemia (AML) cells showed that genes which protected cells from oxidative stress to be the most up-regulated. APR-246 exposure also induced reactive oxygen species (ROS) formation and depleted glutathione in AML cells. The genes most up-regulated by APR-246, confirmed by quantitative real time polymerase chain reaction, were heme oxygenase-1 (HMOX1, also termed HO-1), SLC7A11 and RIT1. Up-regulation of HMOX1, a key regulator of cellular response to ROS, was independent of TP53 mutational status. NFE2L2 (also termed Nrf2), a master regulator of HMOX1 expression, showed transcriptional up-regulation and nuclear translocation by APR-246. Down-regulation of NFE2L2 by siRNA in AML cells significantly increased the antitumoural effects of APR-246. The PI3K inhibitor wortmannin and the mTOR inhibitor rapamycin inhibited APR-246-induced nuclear translocation of NFE2L2 and counteracted the protective cellular responses to APR-246, resulting in synergistic cell killing together with APR-246. In conclusion, ROS induction is important for antileukaemic activities of APR-246 and inhibiting the protective response of the Nrf-2/HMOX1 axis using PI3K inhibitors, enhances the antileukaemic effects.

    A phase II study of vorinostat (MK-0683) in patients with polycythaemia vera and essential thrombocythaemia2013In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 162, no 4, p. 498-508Article in journal (Refereed)
    Abstract [en]

    Inhibition of histone deacetylases may be an important target in patients with myeloproliferative neoplasms. This investigator-initiated, non-randomized, open-label phase II multi-centre study included 63 patients (19 essential thrombocythaemia, 44 polycythaemia vera) from 15 centres. The primary objective was to evaluate if vorinostat was followed by a decline in clonal myeloproliferation as defined by European Leukaemia Net. Thirty patients (48%) completed the intervention period (24 weeks of therapy). An intention-to-treat response rate of 35% was identified. Pruritus was resolved [19% to 0% (P=0.06)] and the prevalence of splenomegaly was lowered from 50% to 27% (P=0.03). Sixty-five per cent of the patients experienced a decrease in JAK2 V617F allele burden (P=0.006). Thirty-three patients (52% of patients) discontinued study drug before end of intervention due to adverse events (28 patients) or lack of response (5 patients). In conclusion, vorinostat showed effectiveness by normalizing elevated leucocyte and platelet counts, resolving pruritus and significantly reducing splenomegaly. However, vorinostat was associated with significant side effects resulting in a high discontinuation rate. A lower dose of vorinostat in combination with conventional and/or novel targeted therapies may be warranted in future studies.

    Paediatric B-cell precursor acute lymphoblastic leukaemia with t(1;19)(q23;p13): clinical and cytogenetic characteristics of 47 cases from the Nordic countries treated according to NOPHO protocols2011In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 155, no 2, p. 235-243Article in journal (Refereed)
    Abstract [en]

    The translocation t(1;19)(q23;p13)/der(19) t(1;19) is a risk stratifying aberration in childhood B-cell precursor acute lymphoblastic leukaemia (BCP ALL) in the Nordic countries. We have identified 47 children/adolescents with t(1;19)/der(19) t(1;19)-positive BCP ALL treated on two successive Nordic Society of Paediatric Haematology and Oncology (NOPHO) protocols between 1992 and 2007 and have reviewed the clinical and cytogenetic characteristics of these cases, comprising 1.8% of all cases. The translocation was balanced in 15 cases (32%) and unbalanced in 29 cases (62%). The most common additional chromosome abnormalities were del(9p), i(9q), del(6q), and del(13q). The median age was 7 years, the median white blood cell (WBC) count was 16 x 10(9)/l, and the female/male ratio was 1.2. The predicted event-free survival (EFS) at 5 and 10 years was 0.79, whereas the predicted overall survival (OS) at 5 and 10 years was 0.85 and 0.82, respectively. Nine patients had a bone marrow relapse after a median of 23 months; no patient had a central nervous system relapse. Additional cytogenetic abnormalities, age, gender, WBC count or whether the t(1;19) was balanced or unbalanced did not influence EFS or OS. Compared to cases with t(12,21) and high hyperdiploidy, EFS was similar, but overall survival was worse in patients with t(1;19)/der(19) t(1;19) (P = 0.004).

    Expression of the human germinal-centre-associated lymphoma protein in diffuse large B-cell lymphomas in patients with rheumatoid arthritis2008In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 141, no 1, p. 69-72Article in journal (Refereed)
    Abstract [en]

    Diffuse large B-cell lymphomas (DLBCL) can be subdivided into germinal centre (GC)-like and non-GC-like subtypes by CD10, BCL6 and MUM1/IRF4 status. We previously reported that patients with severe rheumatoid arthritis (RA) are at increased risk of non-GC DLBCL. This study examined a new GC-marker, human germinal-centre-associated lymphoma (HGAL) protein, in RA-DLBCL. Of 111, 38 (34%) DLBCL were HGAL-positive and showed less disseminated disease and a tendency toward improved overall survival compared to HGAL-negative cases. This supports that a majority of RA-DLBCL are of non-GC origin, indicating a specific role for activated peripheral B cells in the pathogenesis of RA-DLBCL.

    Complex and monosomal karyotype are distinct cytogenetic entities with an adverse prognostic impact in paediatric acute myeloid leukaemia: A NOPHO-DBH-AML study2018In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 183, no 4, p. 618-628Article in journal (Refereed)
    Abstract [en]

    Data on occurrence, genetic characteristics and prognostic impact of complex and monosomal karyotype (CK/MK) in children with acute myeloid leukaemia (AML) are scarce. We studied CK and MK in a large unselected cohort of childhood AML patients diagnosed and treated according to Nordic Society for Paediatric Haematology and Oncology (NOPHO)-AML protocols 1993-2015. In total, 800 patients with de novo AML were included. CK was found in 122 (15%) and MK in 41 (5%) patients. CK and MK patients were young (median age 2.1 and 3.3 years, respectively) and frequently had FAB M7 morphology (24% and 22%, respectively). Refractory disease was more common in MK patients (15% vs. 4%) and stem cell transplantation in first complete remission was more frequent (32% vs. 19%) compared with non-CK/non-MK patients. CK showed no association with refractory disease but was an independent predictor of an inferior event-free survival (EFS; hazard ratio [HR] 1.43, P = 0.03) and overall survival (OS; HR 1.48, P = 0.01). MK was associated with a poor EFS (HR 1.57, P = 0.03) but did not show an inferior OS compared to non-MK patients (HR 1.14, P = 0.62). In a large paediatric cohort, we characterized AML with non-recurrent abnormal karyotype and unravelled the adverse impact of CK and MK on prognosis.

    Prognostic scoring systems for myelodysplastic syndromes (MDS) in a population-based setting: a report from the Swedish MDS register2018In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 181, no 5, p. 614-627Article in journal (Refereed)
    Abstract [en]

    The myelodysplastic syndromes (MDS) have highly variable outcomes and prognostic scoring systems are important tools for risk assessment and to guide therapeutic decisions. However, few population-based studies have compared the value of the different scoring systems. With data from the nationwide Swedish population-based MDS register we validated the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R) and the World Health Organization (WHO) Classification-based Prognostic Scoring System (WPSS). We also present population-based data on incidence, clinical characteristics including detailed cytogenetics and outcome from the register. The study encompassed 1329 patients reported to the register between 2009 and 2013, 14% of these had therapy-related MDS (t-MDS). Based on the MDS register, the yearly crude incidence of MDS in Sweden was 2<bold></bold>9 per 100000 inhabitants. IPSS-R had a significantly better prognostic power than IPSS (P<0<bold></bold>001). There was a trend for better prognostic power of IPSS-R compared to WPSS (P=0<bold></bold>05) and for WPSS compared to IPSS (P=0<bold></bold>07). IPSS-R was superior to both IPSS and WPSS for patients aged 70years. Patients with t-MDS had a worse outcome compared to de novo MDS (d-MDS), however, the validity of the prognostic scoring systems was comparable for d-MDS and t-MDS. In conclusion, population-based studies are important to validate prognostic scores in a real-world' setting. In our nationwide cohort, the IPSS-R showed the best predictive power.

    Kinetic analysis of 52Fe-labelled iron(III) hydroxide-sucrose complex following bolus administration using positron emission tomography1999In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 104, no 2, p. 288-295Article in journal (Refereed)
    Abstract [en]

    Kinetic analysis of a single intravenous injection of 100 mg iron(III) hydroxide-sucrose complex (Venofer) mixed with 52Fe(III) hydroxide-sucrose as a tracer was followed for 3-6 h in four generally anaesthetized, artificially ventilated minipigs using positron emission tomography (PET). The amount of injected radioactivity ranged from 30 to 200 MBq. Blood radioactivity, measured by PET in the left ventricle of the heart, displayed a fast clearance phase followed by a slow one. In the liver and bone marrow a fast radioactivity uptake occurred during the first 30 min, followed by a slower steady increase. In the liver a slight decrease in radioactivity uptake was noted by the end of the study. A kinetic analysis using a three-compartment (namely blood pool, reversible and irreversible tissue pools) model showed a fairly high distribution volume in the liver as compared with the bone marrow. In conclusion, the pharmacokinetics of the injected complex was clearly visualized with the PET technique. The organs of particular interest, namely the heart (for blood kinetics), liver and bone marrow could all be viewed by a single setting of a PET tomograph with an axial field of view of 10 cm. The half-life (T1/2) of 52Fe (8.3 h) enables a detailed kinetic study up to 24 h. A novel method was introduced to verify the actual 52Fe contribution to the PET images by removing the interfering radioactive daughter 52mMn positron emissions. The kinetic data fitted the three-compartment model, from which rate constants could be obtained for iron transfer from the blood to a pool of iron in bone marrow or liver to which it was bound during the study period. In addition, there was a reversible tissue pool of iron, which in the liver slowly equilibrated with the blood, to give a net efflux from the liver some hours after i.v. administration. The liver uptake showed a relatively long distribution phase, whereas the injected iron was immediately incorporated into the bone marrow. Various transport mechanisms seem to be involved in the handling of the injected iron complex.

    Pharmacokinetics and red cell utilization of iron(III) hydroxide- sucrose complex in anaemic patients: a study using positron emission tomography1999In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 104, no 2, p. 296-302Article in journal (Refereed)
    Abstract [en]

    The pharmacokinetics of a single intravenous injection of 100 mg iron hydroxide-sucrose complex labelled with a tracer in the form of 52Fe/59Fe was followed in six anaemic patients for a period ranging from 6 to 8 3 h using positron emission tomography (PET). Red cell utilization of the labelled iron was followed for 4 weeks. PET data showed radioactive uptake by the liver, spleen and bone marrow. The uptake by the macrophage-rich spleen demonstrated the reticuloendothelial uptake of this iron preparation, with subsequent effective release of that iron for marrow utilization. Red cell utilization, followed for 4 weeks, ranged from 59% to 97%. The bone marrow influx rate constant was independent of blood iron concentration, indicating non-saturation of the transport system in bone marrow. This implied that higher doses of the iron complex can probably be used in the same setting. A higher influx rate into the marrow compared with the liver seemed to be consistent with higher red cell utilization. This would indicate that early distribution of the injected iron complex may predict the long-term utilization.

    Pharmacokinetics and red cell utilization of 52Fe/59Fe-labelled iron polymaltose in anaemic patients using positron emission tomography2003In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 120, no 5, p. 853-859Article in journal (Refereed)
    Abstract [en]

    Parenteral iron-polysaccharide complexes are increasingly applied. The pharmacokinetics of iron sucrose have been assessed by our group using positron emission tomography (PET). A single intravenous injection of 100 mg iron as iron (III) hydroxide-polymaltose complex, labelled with a tracer in the form of 52Fe/59Fe, was similarly assessed in six patients using PET for about 8 h. Red cell utilization was followed for 4 weeks. Iron polymaltose was similarly distributed to the liver, spleen and bone marrow. However, a larger proportion of this complex was rapidly distributed to the bone marrow. The shorter equilibration phase for the liver, about 25 min, indicates the minimal role of the liver for direct distribution. Splenic uptake also reflected the reticuloendothelial handling of this complex. Red cell utilization ranged from 61% to 99%. Despite the relatively higher uptake by the bone marrow, there was no saturation of marrow transport systems at this dose level. In conclusion, high red cell utilization of iron polymaltose occurred in anaemic patients. The major portion of the injected dose was rapidly distributed to the bone marrow. In addition, the reticuloendothelial uptake of this complex may reflect the safety of polysaccharide complexes. Non-saturation of transport systems to the bone marrow indicated the presence of a large interstitial transport pool, which might possibly be transferrin.

    Genome-wide analysis of cytogenetic aberrations in ETV6/RUNX1-positive childhood acute lymphoblastic leukaemia.2012In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 157, no 4, p. 476-82Article in journal (Refereed)
    Abstract [en]

    The chromosomal translocation t(12;21) resulting in the ETV6/RUNX1 fusion gene is the most frequent structural cytogenetic abnormality among patients with childhood acute lymphoblastic leukaemia (ALL). We investigated 62 ETV6/RUNX1-positive childhood ALL patients by single nucleotide polymorphism array to explore acquired copy number alterations (CNAs) at diagnosis. The mean number of CNAs was 2·82 (range 0-14). Concordance with available G-band karyotyping and comparative genomic hybridization was 93%. Based on three major protein-protein complexes disrupted by these CNAs, patients could be categorized into four distinct subgroups, defined by different underlying biological mechanisms relevant to the aetiology of childhood ALL. When recurrent CNAs were evaluated by an oncogenetic tree analysis classifying their sequential order, the most common genetic aberrations (deletions of 6q, 9p, 13q and X, and gains of 10 and 21) seemed independent of each other. Finally, we identified the most common regions with recurrent gains and losses, which comprise microRNA clusters with known oncogenic or tumour-suppressive roles. The present study sheds further light on the genetic diversity of ETV6/RUNX1-positive childhood ALL, which may be important for understanding poor responses among this otherwise highly curable subset of ALL and lead to novel targeted treatment strategies.

    Mobilization of Philadelphia-negative peripheral blood progenitor cells with chemotherapy and rhuG-CSF in chronic myelogenous leukaemia patients with a poor response to interferon-alpha1998In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 101, no 1, p. 111-8Article in journal (Refereed)
    Abstract [en]

    The purpose of this cooperative study was to evaluate the quantity and quality of Ph1-negative progenitor cells mobilized in the peripheral blood of patients with chronic myelogenous leukaemia soon after aplasia induced by chemotherapy. 32 patients ineligible for allografting who were cytogenetically refractory to interferon-alpha (IFN-alpha) were entered into this study. The chronic phase varied widely, with a median duration of 17 months (range 3-90 months). All patients were treated with intensive conventional chemotherapy regimens and recombinant human granulocyte colony-stimulating factor (rhuG-CSF, lenograstim). Peripheral blood progenitor cells (PBPC) were harvested by leukaphereses during early recovery from chemotherapy-induced aplasia. A total of 119 leukaphereses were performed. Median numbers of CD34+ cells and CFU-GM collected were 2.04 x 10(6)/kg and 2 9 x 10(4)/kg, respectively. There was a significant correlation between white cell count and number of CD34+ cells in the leukaphereses (P = 0.0001, r2 = 0.41, n = 104). A strict correlation between the number of CD34+ cells and CFU-GM in the leukapheretic product (P = 0.0001, r2 = 0.39, n = 110) was observed. 21% of evaluable patients (6/29) achieved a complete cytogenetic remission in the leukapheretic product and the other four patients achieved a major cytogenetic response for an overall response of 35% (10/22 patients). To date, 16 patients have been autografted and are alive. Five of them are Ph1-negative (three patients) or partially Ph1-negative (two patients). In conclusion, despite the high-risk characteristics of this study population, Ph1-negative PBPC were successfully mobilized in more than one-quarter of patients using a chemotherapy plus rhuG-CSF regimen. The importance of this achievement is increased by the current lack of other practical methods of rescuing Ph-negative cells in such patients.

    Releasability of human hypereosinophilic eosinophils is related to the density of the cells1994In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 86, no 1, p. 41-47Article in journal (Refereed)
    Abstract [en]

    The activity of eosinophils and neutrophils with respect to the release of granule proteins was studied in 11 patients with the hypereosinophilic syndrome (HES). Granulocytes or purified eosinophils were stimulated with serum-opsonized Sephadex particles (C3b-induced release), and the released amounts of eosinophil cationic protein (ECP), eosinophils protein-X (EPX) and myeloperoxidase (MPO) were measured by means of specific radioimmunoassays (RIA). Eosinophils obtained from patients with HES released significantly more ECP (P<0·002) and EPX (P<0·01) after 20 min of incubation than cells from the control group. The cellular content of ECP and EPX in eosinophils obtained from the patients with HES was significantly reduced to 50% and 62%, respectively, of the content of these granule proteins of eosinophils from the control group. In separated eosinophils light-density eosinophils released more of both ECP and EPX than normal density eosinophils. There was no difference in MPO release between the patients and the control group. We conclude that the eosinophils from patients with HES have an increased propensity to release their granule proteins and the releasability seems to be related to the density of the cells.

    Ex vivo stimulation of cytomegalovirus (CMV)-specific T cells using CMVpp65-modified dendritic cells as stimulators2003In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 121, no 3, p. 428-38Article in journal (Refereed)
    Abstract [en]

    Cytomegalovirus (CMV) infection is a dangerous complication in immunosuppressed individuals such as allogeneic stem cell transplant patients. CMV disease can be prevented by the early post-transplant transfer of donor-derived, CMV-directed, T cells. Fast and cost efficient methods to generate CMV-specific T cells are, therefore, warranted. The current study utilized peptide-pulsed and adenovirus-transduced dendritic cells (DC) to generate CMV-restricted T cells. After one stimulation with CMV pp65495-503 peptide-pulsed DC and three re-stimulations with peptide-pulsed monocytes, virtually all T cells were CD8+, expressed the relevant T cell receptor and exhibited high peptide-specific lytic activity. After only one stimulation, pp65495-503-restricted T cells could be sorted to a purity of higher than 95% and expanded up to 1000-fold in 2 weeks. This technique may prove useful for the rapid generation of large quantities of specific cytolytic T lymphocytes (CTL) for cell therapy. DC transduced with an adenoviral vector encoding the full-length pp65 protein (Adpp65) were able to simultaneously expand CTL against multiple epitopes of pp65. In addition, they activated CMV-specific CD4+ T-helper cells. This approach would stimulate multiple-epitope populations of pp65-specific T cells and could be made available to patients of any human leucocyte antigen (HLA) haplotype. DC transduced with adenoviral vectors to express full-length antigens may prove to be potent vaccines against viral pathogens and cancer.

    Second allogeneic stem cell transplant for aplastic anaemia: a retrospective study by the severe aplastic anaemia working party of the European society for blood and marrow transplantation2015In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 171, no 4, p. 606-614Article in journal (Refereed)
    Abstract [en]

    We analysed the outcome of a second allogeneic haematopoietic stem cell transplant (alloHSCT) in 162 patients reported to the European Society for Blood and Marrow Transplantation between 1998 and 2009. Donor origin was a sibling in 110 and an unrelated donor in 52 transplants, respectively. The stem cell source was bone marrow in 31% and peripheral blood in 69% of transplants. The same donor as for the first alloHSCT was used in 81% of transplants whereas a change in the choice of stem cell source was reported in 56% of patients, mainly from bone marrow to peripheral blood. Neutrophil and platelet engraftment occurred in 85% and 72% of patients, after a median time of 15 and 17days, respectively. Grade II-IV acute graft-versus-host disease (GVHD) and chronic GVHD occurred in 21% and 37% of patients, respectively. Graft failure (GF) occurred in 42 patients (26%). After a median follow-up of 3.5years, the 5-year overall survival (OS) was 60.7%. In multivariate analysis, the only factor significantly associated with a better outcome was a Karnofsky/Lansky score 80 (higher OS). We conclude that a second alloHSCT is feasible rescue option for GF in SAA, with a successful outcome in 60% of cases.

    CD99 expression is strongly associated with clinical outcome in children with B-cell precursor acute lymphoblastic leukaemia2019In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 184, no 3, p. 418-423Article in journal (Refereed)
    Abstract [en]

    Our study aimed to determine the expression pattern and clinical relevance of CD99 in paediatric B-cell precursor acute lymphoblastic leukaemia (BCP-ALL). Our findings demonstrate that high expression levels of CD99 are mainly found in high-risk BCP-ALL, e.g. BCR-ABL1 and CRLF2(,)(Re/Hi) and that high CD99 mRNA levels are strongly associated with a high frequency of relapse, high proportion of positive for minimal residual disease at day 29 and poor overall survival in paediatric cohorts, which indicate that CD99 is a potential biomarker for BCP-ALL.

    Elevated serum levels of soluble ICAM-1 are elevated in non-Hodgkin´s lymphomas and correlate with tumor burden, disease activity and other diagnostic markers1996In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 92, no 3, p. 639-46Article in journal (Refereed)
    Abstract [en]

    The serum levels of soluble ICAM-1 (CD54) were significantly elevated in patients with non-Hodgkin's lymphomas (NHL, n=127) and hairy cell leukaemia (HCL, n=15) compared with healthy controls (n=31). In high-grade malignant NHL (n=79) the sICAM-1 levels correlated with the tumour mass as reflected in the Ann Arbor staging system but not with bulky disease. Further, the sICAM-1 levels correlated with disease activity as reflected by the presence of B symptoms and with other known prognostic markers. In particular serum thymidine kinase (sTK). In patients with low-grade malignant NHL (n=48) a trend towards higher serum levels of sICAM-1 was found in patients with advanced stage and B symptoms. In both low and high-grade malignant NHL, elevated levels of sICAM-1 were associated with poorer overall and disease-free survival. The present results indicated that sICAM-1 levels have a prognostic power equal to that of other serum markers claimed to be of prognostic value in NHL, namely serum lactate dehydrogenase (LDH), erythrocyte sedimentation rate (ESR), beta-2-microglobulin (beta2m), serum thymidine kinase (sTK), albumin and orosomucoid. The cellular origin and the possible interactions between soluble and surface ICAM-1 and its ligands needs further exploration.

    Soluble vascular cell adhesion molecule-1 (sVCAM-1) is an independent prognostic marker in Hodgkin's disease1998In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 102, no 3, p. 701-9Article in journal (Refereed)
    Abstract [en]

    Serum levels of soluble vascular cell adhesion molecule-1 (sVCAM-1. sCD106) were significantly elevated in patients with Hodgkin's disease (HD) (n = 101) compared to controls (n= 31) (P<0.0001). sVCAM-1 correlated with histology, stage, B-symptoms, and prognostic markers (sICAM-1, sCD30, sIL-2R, LDH). sVCAM-1, sICAM-1 and sCD30 added independent prognostic information for both disease-free and overall survival. 14 biopsies from 13 patients with HD were immunostained for VCAM-1 and ICAM-1. The vascular endothelium stained positive for VCAM-1 in 10/12 evaluable biopsies and for ICAM-1 in all evaluable biopsies. A stromal expression of both adhesion molecules precluded a precise evaluation of HRS-cells. This led us to investigate VCAM-1 (and ICAM-1) expression in six Hodgkin cell lines (HDLM-2, L428, L540, L591, DEV, KM-H2). Two cell lines stained positive for VCAM-1 (HDLM-2, L591). All cell lines stained positive for ICAM-1. sVCAM-1 is a new prognostic marker in HD; its predictive power equals or surpasses that of sCD30 and sICAM-1. Furthermore, two Hodgkin cell lines stained positive for VCAM-1. This indicates that VCAM-1 may be expressed by some HD tumour cells in vivo.

    Elevated serum levels of soluble vascular cell adhesion molecule-1(sVCAM-1) closely reflect tumour burden in chronic B-lymphocytic leukaemia1998In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 103, no 4, p. 1129-1137Article in journal (Refereed)
    Abstract [en]

    The present study is the first to report elevated serum levels of soluble (s)VCAM-1 in B-cell chronic lymphocytic leukaemia (B-CLL). A large cohort of 106 untreated patients was studied. sVCAM-1 was compared to known prognostic serum markers (soluble (s)ICAM-1; lactate dehydrogenase, LDH; sCD23; thymidine kinase, TK; beta2microglobulin, beta2m). The serum levels of sVCAM-1 reflected tumour burden as expressed by Binet/Rai stages more closely than any other marker. sVCAM-1 also reflected the kinetics of the disease as revealed by lymphocyte doubling time. sVCAM-1 was the only one of the studied markers which showed elevated levels in smouldering disease compared to controls. sVCAM-1, sICAM-1 and sCD23 (but not LDH, TK, beta2m) separated smouldering from non-smouldering B-CLL. Only sICAM-1, sCD23 and TK added independent prognostic information for survival to that of stage and lymphocyte doubling time. The expression of both adhesion molecules was examined in lymph node and splenic specimens. VCAM-1 and ICAM-1 were overexpressed by vascular endothelium and stroma, but the intensity of expression correlated poorly with serum levels of the soluble molecules. In conclusion, serum levels of sVCAM-1 correlated with tumour burden and other prognostic markers in B-CLL. VCAM-1 was overexpressed in tumour tissue as was ICAM-1. sVCAM-1 could prove a valuable marker in younger early-stage patients eligible for therapeutic trials.

    Verification that common variation at 2q37.1, 6p25.3, 11q24.1, 15q23, and 19q13.32 influences chronic lymphocytic leukaemia risk2010In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 150, no 4, p. 473-479Article in journal (Refereed)
    Abstract [en]

    P>A recent genome wide association study of chronic lymphocytic leukaemia (CLL) provided evidence that common variation at 2q13 (rs17483466), 2q37.1 (rs13397985), 6p25.3 (rs872071), 11q24.1 (rs735665), 15q23 (rs7176508) and 19q13.32 (rs11083846) affects CLL risk. To verify and further explore the relationship between these variants and CLL risk we genotyped case-control datasets from Spain and Sweden (824 cases, 850 controls). Combined data provided statistically significant support for an association between genotypes at rs13397985, rs872071, rs735665, rs7176508 and rs11083846 and CLL risk. CLL risk increased with increasing numbers of risk alleles (P-trend = 1 center dot 40 x 10-15), consistent with a polygenic model of disease susceptibility. These data validate the relationship between common variation and risk of CLL.

    Phase II trial of zanolimumab (HuMax-CD4) in relapsed or refractory non-cutaneous peripheral T cell lymphoma2010In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 150, no 5, p. 565-573Article in journal (Refereed)
    Abstract [en]

    The efficacy and safety of zanolimumab (HuMax-CD4) in patients with relapsed or refractory peripheral T Cell lymphoma (PTCL) was evaluated. Twenty-one adult patients with relapsed or refractory CD4+ PTCL of non-cutaneous type (angioimmunoblastic T cell lymphoma (AITL) n = 9, PTCL-not otherwise specified (NOS) n = 7, anaplastic large cell lymphoma (ALCL) n = 4 and enteropathy type T cell lymphoma n = 1) were treated in a single-arm multi-centre study, with weekly intravenous infusions of zanolimumab 980 mg for 12 weeks. Median age was 69 years (range 26-85). Seventeen of the patients had advanced stage disease (Ann Arbor stages III-IV). Objective tumour responses were obtained in 24% of the patients with two complete responses unconfirmed (CRu) and three partial responses (PR). One of the CRus lasted more than 252 d. Responses were obtained in different PTCL entities: AITL (n = 3), ALCL (n = 1) and PTCL-NOS (n = 1). In general, the trial drug was well tolerated with no major toxicity. Zanolimumab at a dose of 980 mg weekly demonstrated clinical activity and an acceptable safety profile in this poor-prognosis patient population, suggesting that the potential benefit combining zanolimumab with standard chemotherapy in the treatment of PTCL should be investigated.

    Expression of ribosomal and actin network proteins and immunochemotherapy resistance in diffuse large B cell lymphoma patients2018In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 181, no 6, p. 770-781Article in journal (Refereed)
    Abstract [en]

    Diffuse large B cell lymphoma (DLBCL) patients with early relapse or refractory disease have a very poor outcome. Immunochemotherapy resistance will probably, also in the era of targeted drugs, remain the major cause of treatment failure. We used proteomic mass spectrometry to analyse the global protein expression of micro-dissected formalin-fixed paraffin-embedded tumour tissues from 97 DLBCL patients: 44 with primary refractory disease or relapse within 1year from diagnosis (REF/REL), and 53 who were progression-free more than 5years after diagnosis (CURED). We identified 2127 proteins: 442 were found in all patients and 102 were differentially expressed. Sixty-five proteins were overexpressed in REF/REL patients, of which 46 were ribosomal proteins (RPs) compared with 2 of the 37 overexpressed proteins in CURED patients (P=7<bold></bold>6x10(-10)). Twenty of 37 overexpressed proteins in CURED patients were associated with actin regulation, compared with 1 of 65 in REF/REL patients (P=1<bold></bold>4x10(-9)). Immunohistochemical staining showed higher expression of RPS5 and RPL17 in REF/REL patients while MARCKS-like protein, belonging to the actin network, was more highly expressed in CURED patients. Even though functional studies aimed at individual proteins and protein interactions to evaluate potential clinical effect are needed, our findings suggest new mechanisms behind immunochemotherapy resistance in DLBCL.

    Obesity as a predictor of treatment-related toxicity in children with acute lymphoblastic leukaemia2022In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 196, no 5, p. 1239-1247Article in journal (Refereed)
    Abstract [en]

    Obesity is associated with poor outcomes in childhood acute lymphoblastic leukaemia (ALL). We explored whether severe treatment-related toxicity and treatment delays could explain this observation. This study included 1 443 children aged 2 center dot 0-17 center dot 9 years with ALL treated with the Nordic Society of Pediatric Haematology and Oncology (NOPHO) ALL2008 non-high-risk protocol. Prospective treatment-related toxicities registered every three-month interval were used. Patients were classified according to sex- and age-adjusted international childhood cut-off values, corresponding to adult body mass index: underweight, <17 kg/m(2); healthy weight, 17 to <25 kg/m(2); overweight, 25 to <30 kg/m(2); and obese, >= 30 kg/m(2). Obese children had a higher incidence rate ratio (IRR) for severe toxic events {IRR: 1 center dot 55 [95% confidence interval (CI) 1 center dot 07-2 center dot 50]}, liver and kidney failures, bleeding, abdominal complication, suspected unexpected severe adverse reactions and hyperlipidaemia compared with healthy-weight children. Obese children aged >= 10 years had increased IRRs for asparaginase-related toxicities compared with healthy-weight older children: thromboses [IRR 2 center dot 87 (95% CI 1 center dot 00-8 center dot 21)] and anaphylactic reactions [IRR 7 center dot 95 (95% CI 2 center dot 15-29 center dot 37)] as well as higher risk for truncation of asparaginase [IRR 3 center dot 54 (95% CI 1 center dot 67-7 center dot 50)]. The high prevalence of toxicity and a higher risk of truncation of asparaginase may play a role in the poor prognosis of obese children aged >= 10 years with ALL.

    The new ID-heparin/PF4 antibody test for rapid detection of heparin-induced antibodies in comparison with functional and antigenic assays.2002In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 116, no 4, p. 887-91Article in journal (Refereed)
    Abstract [en]

    Heparin-induced thrombocytopenia (HIT) is an immune-mediated complication of heparin treatment. Several in vitro assays are available to detect the causative HIT antibodies: functional assays, usually requiring freshly prepared platelets and immunological tests based on the enzyme-linked immunosorbent assay (ELISA) principle. We compared a new, simple and rapid test based on the ID-microtyping particle agglutination system with 14C-serotonin release assay, heparin-induced platelet activation (HIPA) test and two ELISAs. Sera from 100 confirmed HIT patients, 20 serologically negative suspected HIT patients and 20 healthy blood donors were used. The specificity and sensitivity of the new test was similar to the functional assays. Compared with the ELISAs, specificity was better at the cost of reduced sensitivity. As in all other immunological tests, HIT antibodies against less typical antigens, such as interleukin (IL)-8 or neutrophil-activating peptide (NAP) 2 could not be detected. Thus, although the ID-Heparin/PF4 antibody test seems to be a quick, reliable and robust test to determine the presence of HIT antibodies, it should still be combined with a functional assay if possible. Evaluation of the test in a prospective setting as well as interlaboratory variation should be assessed as a next step.

    Trends in the prevalence, incidence and survival of non-Hodgkin lymphoma subtypes during the 21st century - a Swedish lymphoma register study2020In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 189, no 6, p. 1083-1092Article in journal (Refereed)
    Abstract [en]

    Non-Hodgkin lymphoma (NHL) prognosis has improved in recent years, yet the number of patients living with the diagnosis, i.e. the prevalence, has seldom been reported. The prevalence provides a measure of the burden of disease, useful for healthcare planning and to optimise resource allocation. We provide a systematic presentation of temporal trends in absolute numbers of prevalent patients by NHL subtypes, linking them to trends in incidence, survival and mortality. Patients diagnosed 2000-2016 were identified in the national Swedish lymphoma register. Incidence and mortality rates, relative survival and prevalence were estimated for NHL overall and for major clinical and morphological subtypes. Poisson regression was used to test for temporal trends. Increasing incidence and improved survival have led to a 47% increase in the five-year prevalence of NHL overall in 2016 compared to 2004. An increasing prevalence was observed for all investigated subtypes during the study period, but most notably for diffuse large B cell lymphomas among aggressive subtypes (66%), and marginal zone lymphomas among indolent subtypes (135%). This dramatic increase in NHL prevalence underscores the need to develop and evaluate alternative follow-up schemes to use resources efficiently and still ensure optimal care of lymphoma survivors.

    Late relapses in Hodgkin lymphoma - should we search for the needle in the haystack?2022In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 198, no 1, p. 11-13Article in journal (Other academic)
    Abstract [en]

    Hodgkin lymphoma is among the most curable cancers. For patients in remission for 24 months, residual lifetime becomes close to that of the background population. However, late relapses can occur after several years and, as shown by Andersen et al., the outcomes are not always good.

    Reproduction patterns among non-Hodgkin lymphoma survivors by subtype in Sweden, Denmark and Norway: A population-based matched cohort study2023In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 202, no 4, p. 785-795Article in journal (Refereed)
    Abstract [en]

    Previous studies concerning reproductive patterns among non-Hodgkin lymphoma (NHL) survivors are scarce and those available have reported conflicting results. Treatment regimens vary considerably between aggressive and indolent NHL and studies of reproductive patterns by subtypes are warranted. In this matched cohort study, we identified all NHL patients aged 18-40 years and diagnosed between 2000 and 2018 from the Swedish and Danish lymphoma registers, and the clinical database at Oslo University Hospital (n = 2090). Population comparators were matched on sex, birth year and country (n = 19 427). Hazard ratios (HRs) were estimated using Cox regression. Males and females diagnosed with aggressive lymphoma subtypes had lower childbirth rates (HRfemale: 0.43, 95% CI: 0.31-0.59, HRmale: 0.61, 95% CI: 0.47-0.78) than comparators during the first 3 years after diagnosis. For indolent lymphomas, childbirth rates were not significantly different from comparators (HRfemale: 0.71, 95% CI: 0.48-1.04, HRmale: 0.94, 95% CI: 0.70-1.27) during the same period. Childbirth rates reached those of comparators for all subtypes after 3 years but the cumulative incidence of childbirths was decreased throughout the 10-year follow-up for aggressive NHL. Children of NHL patients were more likely to be born following assisted reproductive technology than those of comparators, except for male indolent lymphoma patients. In conclusion, fertility counselling is particularly important for patients with aggressive NHL.

    Incidence, Risk Factors for and Outcomes of Transplant-Associated Thrombotic Microangiopathy2020In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 189, no 6, p. 1171-1181Article in journal (Refereed)
    Abstract [en]

    Transplant-associated thrombotic microangiopathy (TA-TMA) is a complication of allogeneic transplantation (allo-HCT). The incidence and risk factors associated with TA-TMA are not well known. A retrospective analysis from the Center for International Blood and Marrow Transplant Research (CIBMTR) was conducted including patients receiving allo-HCT between 2008 and 2016, with the primary objective of evaluating the incidence of TA-TMA. Secondary objectives included identification of risk factors associated with TA-TMA, and the impact of TA-TMA on overall survival and the need for renal replacement therapy (RRT). Among 23,665 allo-HCT recipients, the 3-year cumulative incidence of TA-TMA was 3%. Variables independently-associated with increased incidence of TA-TMA included female sex, prior autologous transplant, primary disease (acute lymphoblastic leukaemia and severe aplastic anaemia), donor type (mismatched or unrelated donor), conditioning intensity (myeloablative), GVHD prophylaxis (sirolimus + calcineurin inhibitor), pre-transplant kidney dysfunction and acute GVHD (time-varying effect). TA-TMA was associated with higher mortality (HR = 3 center dot 1, 95% Confidence Interval [CI] = 2 center dot 8-16 center dot 3) and RRT requirement (HR = 7 center dot 1, 95% CI = 5 center dot 7-311 center dot 6). This study provides epidemiologic data on TA-TMA and its impact on transplant outcomes. Increased awareness of the risk factors will enable providers to be vigilant of this uncommon but serious transplant complication. The results will also provide benchmarking for future study designs and comparisons.

    Inhibition of tissue factor expression in human peripheral blood monocytes exposed to cytokines1996In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 95, no 2, p. 249-257Article in journal (Refereed)
    Abstract [en]

    Interleukin (IL)-4, IL-10, IL-13 and transforming growth factor beta (TGF-beta) are known to regulate several monocyte functions, including inhibition of the synthesis of different cytokines. Using quantitative RT-PCR and flow cytometry analysis we investigated the effects of these cytokines on bacterial lipopolysaccharide (LPS)-induced tissue factor (TF) expression in human monocytes. The effects of IL-4 and IL-10 on monocyte chemoattractant protein-1 (MCP-1)-and C-reactive protein (CRP)-induced TF expression were also studied. A direct comparison revealed that IL-4, IL-10 and IL-13 all down-regulated LPS-induced TF expression in a concentration-dependent manner without the need for priming. In contrast, TGF-beta required 4 h of priming to inhibit TF expression induced by LPS. IL-10 was the most powerful inhibitor, causing almost complete inhibition at 5 ng/ml. IL-4 and IL-13 exhibited a significantly lower inhibitory capacity even at concentrations of 100 ng/ml. IL-4 and IL-10 showed similar concentration-dependent inhibition of MCP-1- and CRP-induced TF expression. We also showed that the regulatory effect of the interleukins occurred at the mRNA level. In vivo, these inhibitory cytokines may play an important regulatory role in preventing thrombosis. IL-10, in particular, may be a possible candidate as a TF-preventing drug.

    15-year follow-up of the Second Nordic Mantle Cell Lymphoma trial (MCL2): prolonged remissions without survival plateau2016In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 175, no 3, p. 410-418Article in journal (Refereed)
    Abstract [en]

    In recent decades, the prognosis of Mantle Cell Lymphoma (MCL) has been significantly improved by intensified first-line regimens containing cytarabine, rituximab and consolidation with high-dose-therapy and autologous stem cell transplantation. One such strategy is the Nordic MCL2 regimen, developed by the Nordic Lymphoma Group. We here present the 15-year updated results of the Nordic MCL2 study after a median follow-up of 114years: For all patients on an intent-to-treat basis, the median overall and progression-free survival was 127 and 85years, respectively. The MCL International Prognostic Index (MIPI), biological MIPI, including Ki67 expression (MIPI-B) and the MIPI-B including mIR-18b expression (MIPI-B-miR), in particular, significantly divided patients into distinct risk groups. Despite very long response durations of the low and intermediate risk groups, we observed a continuous pattern of relapse and the survival curves never reached a plateau. In conclusion, despite half of the patients being still alive and 40% in first remission after more than 12years, we still see an excess disease-related mortality, even among patients experiencing long remissions. Even though we consider the Nordic regimen as a very good choice of regimen, we recommend inclusion in prospective studies to explore the benefit of novel agents in the frontline treatment of MCL.

    Impact of ABCB1 single nucleotide polymorphisms 1236C>T and 2677G>T on overall survival in FLT3 wild-type de novo AML patients with normal karyotype2014In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 167, no 5, p. 671-680Article in journal (Refereed)
    Abstract [en]

    Drug resistance is a clinically relevant problem in the treatment of acute myeloid leukaemia (AML). We have previously reported a relationship between single nucleotide polymorphisms (SNPs) of ABCB1, encoding the multi-drug transporter P-glycoprotein, and overall survival (OS) in normal karyotype (NK)-AML. Here we extended this material, enabling subgroup analysis based on FLT3 and NPM1 status, to further elucidate the influence of ABCB1 SNPs. De novo NK-AML patients (n = 201) were analysed for 1199G>A, 1236C>T, 2677G>T/A and 3435C>T, and correlations to outcome were investigated. FLT3 wild-type 1236C/C patients have significantly shorter OS compared to patients carrying the variant allele; medians 20 vs. 49 months, respectively, P = 0.017. There was also an inferior outcome in FLT3 wild-type 2677G/G patients compared to patients carrying the variant allele, median OS 20 vs. 35 months, respectively, P = 0.039. This was confirmed in Cox regression analysis. Our results indicate that ABCB1 1236C>T and 2677G>T may be used as prognostic markers to distinguish relatively high risk patients in the intermediate risk FLT3 wild-type group, which may contribute to future individualizing of treatment strategies.

    Successful tyrosine kinase inhibitor discontinuation outside clinical trials - data from the population-based Swedish chronic myeloid leukaemia registry2021In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 193, no 5, p. 915-921Article in journal (Refereed)
    Abstract [en]

    Clinical trials show that tyrosine kinase inhibitor (TKI) treatment can be discontinued in selected patients with chronic myeloid leukaemia (CML). Although updated CML guidelines support such procedure in clinical routine, data on TKI stopping outside clinical trials are limited. In this retrospective study utilising the Swedish CML registry, we examined TKI discontinuation in a population-based setting. Out of 584 patients diagnosed with chronic-phase CML (CML-CP) in 2007-2012, 548 had evaluable information on TKI discontinuation. With a median follow-up of nine years from diagnosis, 128 (23%) discontinued TKI therapy (>= 1 month) due to achieving a DMR (deep molecular response) and 107 (20%) due to other causes (adverse events, allogeneic stem cell transplant, pregnancy, etc). Among those stopping in DMR, 49% re-initiated TKI treatment (median time to restart 4 center dot 8 months). In all, 38 patients stopped TKI within a clinical study and 90 outside a study. After 24 months 41 center dot 1% of patients discontinuing outside a study had re-initiated TKI treatment. TKI treatment duration pre-stop was longer and proportion treated with second-generation TKI slightly higher outside studies, conceivably affecting the clinical outcome. In summary we show that TKI discontinuation in CML in clinical practice is common and feasible and may be just as successful as when performed within a clinical trial.

    Outcome of ETV6/RUNX1-positive childhood acute lymphoblastic leukaemia in the NOPHO-ALL-1992 protocol: frequent late relapses but good overall survival2008In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 140, no 6, p. 665-672Article in journal (Refereed)
    Abstract [en]

    The prognostic impact of t(12;21)(p13;q22) [ETV6/RUNX1 fusion] in paediatric acute lymphoblastic leukaemia (ALL) has been extensively debated, particularly with regard to the frequency of late relapses and appropriate treatment regimens. We have retrospectively collected 679 ALLs with known ETV6/RUNX1 status, as ascertained by fluorescence in situ hybridization or reverse-transcription polymerase chain reaction, treated according to the Nordic Society of Paediatric Haematology and Oncology -ALL-1992 protocol. The assigned risk groups/treatment modalities for the 171 (25%) patients with t(12;21)-positive ALLs were 74 (43%) standard risk, 71 (42%) intermediate risk and 26 (15%) high risk. The 5- and 10-year event-free survival (EFS) of the 171 patients was 80% and 75% respectively, with no significant differences among the three risk groups. Most of the relapses occurred in boys and were late, with almost 50% of all relapses occurring >= 5 years after diagnosis. Of all relapses after 6 years, 80% occurred in the t(12;21)-positive group. The overall survival was 94% at 5 years and 88% at 10 years; thus, the treatment of patients in second or later remission is usually successful. As yet, there is no reliable plateau in the EFS curve, a fact that raises the question as to when the prognostic ramifications of ALLs harbouring ETV6/RUNX1 should be evaluated.

    Strategic use of an adenoviral vector for rapid and efficient ex vivo-generation of cytomegalovirus pp65-reactive cytolytic and helper T cells2008In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 141, no 2, p. 188-199Article in journal (Refereed)
    Abstract [en]

    Cytomegalovirus (CMV) reactivation can cause severe complications for transplant patients. Such patients can be protected against CMV-associated diseases through reconstitution of donor-derived CMV-reactive cytolytic and helper T cells. We have developed a strategic protocol for efficient simultaneous generation of CMV-reactive CD8+ and CD4+ T cells ex vivo. The protocol uses peripheral blood lymphocytes (PBLs), antigen-modified mature dendritic cells (DCs) generated in only 3 days and an adenoviral vector encoding the CMV pp65 antigen (Adpp65) both as an endogenous and exogenous source of antigen. PBLs stimulated once with Adpp65-transduced DCs (endogenously expressed pp65) resulted in preferential activation and expansion of pp65-specific CD8+ T cells while PBLs stimulated with DCs pulsed with cell lysate from Adpp65-transduced autologous monocytes (exogenously expressed pp65) yielded pp65-specific CD4+ T cells. Stimulation with double-modified DCs efficiently activated and expanded cytolytic and helper T cells simultaneously. The frequency of T cells producing interferon (IFN)-γ in response to pp65 increased after one stimulation on average 9.6-fold to 4.3% for CD8+ T cells and 25.8-fold to 6.5% for CD4+ T cells. This implies that sufficient number of pp65-specific cytolytic and helper T cells for adoptive transfer may be obtained in only two weeks.

A Nordic Society of Paediatric Haematology and Oncology (NOPHO) pilot study2011In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 155, no 2, p. 244-247Article in journal (Refereed)
    Abstract [en]

    This study explored the feasibility and toxicity of individualized toxicity-titrated 6-mercaptopurine (6MP) dose increments during post-remission treatment with High-dose methotrexate (HDM) (5000 mg/m(2), x3) in 38 patients with Childhood (ALL). Patients were increased in steps of 25 mg 6MP/m(2) per day if they did not develop myelotoxicity within 2 weeks after HDM. 6MP could be increased in 31 patients (81%). Toxicity was acceptable and did not differ significantly between groups. Patients receiving 75 mg/m(2) per day had significantly shorter duration of treatment interruptions of 6MP than the remaining patients (P = 0.03). This study shows individualized toxicity-titrated 6MP dosing during consolidation is feasible without increased risk of toxicity.

    Increased in vitro cellular drug resistance is related to poor outcome in high-risk childhood acute lymphoblastic leukaemia2003In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 122, no 3, p. 376-385Article in journal (Refereed)
    Abstract [en]

    Summary. We determined the in vitro cellular drug resistance in 370 children with newly diagnosed acute lymphoblastic leukaemia (ALL). The resistance to each of 10 drugs was measured by the fluorometric microculture cytotoxicity assay (FMCA) and was related to clinical outcome. The median follow-up time was 41 months. Risk-group stratified analyses indicated that in vitro resistance to dexamethasone, doxorubicin and amsacrine were each significantly related to the probability of disease-free survival. In the high-risk (HR) group, increased in vitro resistance to dexamethasone (P = 0·014), etoposide (P = 0·025) and doxorubicin (P = 0·05) was associated with a worse clinical outcome. Combining the results for these drugs provided a drug resistance score with an independent prognostic significance superior to that of any other factor studied, with a relative risk of relapse in the most resistant group 9·8 times that in the most sensitive group (P = 0·007). The results in the intermediate-risk (IR) and standard-risk (SR) groups were less clear cut. In conclusion, our data indicate that in vitro testing of cellular drug resistance can be used to predict the clinical outcome in HR ALL, while the final evaluation of the results in IR and SR patients must await longer follow-up.

    Nordic MCL2 trial update: six-year follow-up after intensive immunochemotherapy for untreated mantle cell lymphoma followed by BEAM or BEAC plus autologous stem-cell support: still very long survival but late relapses do occur2012In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 158, no 3, p. 355-362Article in journal (Refereed)
    Abstract [en]

    Mantle cell lymphoma (MCL) is a heterogenic non-Hodgkin lymphoma entity, with a median survival of about 5 years. In 2008 we reported the early based on the median observation time of 4 years results of the Nordic Lymphoma Group MCL2 study of frontline intensive induction immunochemotherapy and autologous stem cell transplantation (ASCT), with more than 60% event-free survival at 5 years, and no subsequent relapses reported. Here we present an update after a median observation time of 6.5 years. The overall results are still excellent, with median overall survival and response duration longer than 10 years, and a median event-free survival of 7.4 years. However, six patients have now progressed later than 5 years after end of treatment. The international MCL Prognostic Index (MIPI) and Ki-67-expression were the only independent prognostic factors. Subdivided by the MIPI-Biological Index (MIPI + Ki-67, MIPI-B), more than 70% of patients with low-intermediate MIPI-B were alive at 10 years, but only 23% of the patients with high MIPI-B. These results, although highly encouraging regarding the majority of the patients, underline the need of a risk-adapted treatment strategy for MCL.

    High tumour plasma cell infiltration reflects an important microenvironmental component in classic Hodgkin lymphoma linked to presence of B‐symptoms2018In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, British Journal of Haematology, Vol. 184, no 2, p. 192-201Article in journal (Refereed)
    Abstract [en]

    Plasma cells are important prognostic actors in different malignancies. The tumour microenvironmental composition in classic Hodgkin lymphoma (cHL) is a major prognostic key element; however, clinicopathological studies regarding plasma cells in cHL are lacking. The aim of this study was to investigate CD138+ (also termed SDC1+) plasma cell and IgG4 producing (IgG4+) plasma cells infiltration in the microenvironment of cHL. Immunohistochemistry with anti-CD138 and IgG4 antibodies was performed on diagnostic tumour biopsies from 124 patients with cHL, on tissue micro array (TMA). In 120 cases, CD138+ plasma cell-infiltration was associated with the presence of B-symptoms (P = 0·028) and advanced stage, IIB-IVB (P = 0·009). In multivariate analysis, CD138+ plasma cells correlated with eosinophil infiltration (P = 0·013). The subgroup of IgG4+ plasma cells was analysed in 122 cases and only correlated to CD138+ plasma cells (P = 0·004). Patients with high proportion of tumour infiltrating CD138+ plasma cells (defined as ≥10%), had a more inferior event-free survival (P = 0·007) and overall survival (P = 0·004) than patients with a low proportion of infiltrating CD138+ plasma cells (<10%), although significance was not maintained in multivariate analysis. In summary, a high proportion of tumour-associated plasma cells in cHL reflect an important component in the microenvironment of cHL.

    Checkpoint CD47 expression in classical Hodgkin lymphoma2022In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 197, no 5, p. 580-589Article in journal (Refereed)
    Abstract [en]

    The glycoprotein CD47 regulates antiphagocytic activity via signal regulatory protein alpha (SIRPa). This study investigated CD47 expression on Hodgkin and Reed–Sternberg (HRS) cells in the classical Hodgkin lymphoma (cHL) tumour microenvironment and its correlation with prognosis, programmed-death (PD) immune markers, and SIRPa+ leukocytes. We conducted immunohistochemistry with CD47 and SIRPa antibodies on diagnostic biopsies (tissue microarrays) from cHL patients from two cohorts (n = 178). In cohort I (n = 136) patients with high expression of CD47 on HRS cells (n = 48) had a significantly inferior event-free survival [hazard ratio (HR) = 5.57; 95% confidence interval (CI), 2.78–11.20; p < 0.001] and overall survival (OS) (HR = 8.54; 95% CI, 3.19–22.90; p < 0.001) compared with patients with low expression (n = 88). The survival results remained statistically significant in multivariable Cox regression adjusted for known prognostic factors. In cohort II (n = 42) high HRS cell CD47 expression also carried shorter event-free survival (EFS) (HR = 5.96; 95% CI, 1.20–29.59; p = 0.029) and OS (HR = 5.61; 95% CI, 0.58–54.15; p = 0.136), although it did not retain statistical significance in the multivariable analysis. Further, high CD47 expression did not correlate with SIRPa+ leukocytes or PD-1, PD-L1 and PD-L2 expression. This study provides a deeper understanding of the role of CD47 in cHL during an era of emerging CD47 therapies.

    Comorbidities and sex differences in causes of death among mantle cell lymphoma patients: A nationwide population-based cohort study2020In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 189, no 1, p. 106-116Article in journal (Refereed)
    Abstract [en]

    The prognosis for mantle cell lymphoma (MCL) remains poor. Our aim was to assess the impact of comorbidities on survival and causes of death. For 1,385 MCL patients (1,009 males, 376 females) diagnosed in 2000-2014 (median age 71 years, range 22-96) comorbidities ≤ 10 years of diagnosis were classified according to the Charlson comorbidity index (CCI; 0, 1, 2+). Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated to compare lymphoma-specific and all-cause mortality rates. Model-based predictions were used to obtain probabilities of death. Overall, 44% had any comorbidity (CCI 1+) and 28% severe comorbidity (CCI 2+). Over a median follow-up of 3·7 years (range 0-16), 633 (46%) died, the majority (76%) from lymphoma. Severe comorbidity was independently associated with higher all-cause [hazard ratio (HR) = 1·52; 95% CI: 1·24-1·85) and lymphoma-specific mortality (HR = 1·31; 95% CI: 1·04-1·65). Particularly among patients with connective tissue, renal and psychiatric diseases, and dementia. Among females with any comorbidity, non-lymphoma deaths represented a larger proportion of all deaths, compared to males with any comorbidity. In general, more efficient lymphoma treatments need to be considered also for patients with severe comorbidity. However, among females with any comorbidity, the likelihood of non-lymphoma death was still considerable, perhaps favouring a more liberal use of a "wait and watch" approach.

    Maintenance treatment with azacytidine for patients with high-risk myelodysplastic syndromes (MDS) or acute myeloid leukaemia following MDS in complete remission after induction chemotherapy2010In: British Journal of Haematology, ISSN 0007-1048, E-ISSN 1365-2141, Vol. 150, no 3, p. 293-302Article in journal (Refereed)
    Abstract [en]

    This prospective Phase II study is the first to assess the feasibility and efficacy of maintenance 5-azacytidine for older patients with high-risk myelodysplastic syndrome (MDS), chronic myelomonocytic leukaemia and MDS-acute myeloid leukaemia syndromes in complete remission (CR) after induction chemotherapy. Sixty patients were enrolled and treated by standard induction chemotherapy. Patients that reached CR started maintenance therapy with subcutaneous azacytidine, 5/28 d until relapse. Promoter-methylation status of CDKN2B (P15 ink4b), CDH1 and HIC1 was examined pre-induction, in CR and 6, 12 and 24 months post CR. Twenty-four (40%) patients achieved CR after induction chemotherapy and 23 started maintenance treatment with azacytidine. Median CR duration was 13·5 months, >24 months in 17% of the patients, and 18–30·5 months in the four patients with trisomy 8. CR duration was not associated with CDKN2B methylation status or karyotype. Median overall survival was 20 months. Hypermethylation of CDH1 was significantly associated with low CR rate, early relapse, and short overall survival (P = 0·003). 5-azacytidine treatment, at a dose of 60 mg/m2 was well tolerated. Grade III-IV thrombocytopenia and neutropenia occurred after 9·5 and 30% of the cycles, respectively, while haemoglobin levels increased during treatment. 5-azacytidine treatment is safe, feasible and may be of benefit in a subset of patients.
