  • Biphenotypic bigenotypic lymphoma with simultaneous expression of PAX5/BSAP and B- and T-cell markers
  • 2007

    • Lymphomas are currently categorized according to their origin from a B or T lymphocyte. Immature and less commonly mature (peripheral) lymphomas may harbor rearrangements of both the B- and T-cell antigen receptor genes (dual genotype or bigenotype). Rarely, cells in lymphoma with a single genotype simultaneously express both B- and T-cell markers (biphenotypic lymphomas). We discuss the diagnostic and clinical implications in the case of a 42-yr-old female with a peripheral CD30(+) lymphoma that displayed both characteristic B- and T-cell surface antigens and clonal rearrangement of B- and T-cell antigen receptor gene loci. Simultaneous nuclear expression of the transcription factor gene PAX5 suggested that this major driver of B-cell differentiation did not preclude expression of CD3 epsilon, generally assumed to be a T-cell associated antigen.

    • ObjectivesBacterial infections are common and a major cause of morbidity and mortality in multiple myeloma (MM). We have investigated the function of polymorphonuclear leukocyte (PMN), the immune system's first line of defense against bacteria, in peripheral blood (PB) and bone marrow (BM) samples from patients with newly diagnosed MM (NDMM), smoldering MM (SMM), monoclonal gammopathy of undetermined significance (MGUS) and healthy controls.MethodsPhagocytosis and oxidative burst in PMN cells from patients and healthy donors were investigated using PhagoTest and PhagoBurst assay.ResultsPMN from NDMM, SMM, and MGUS patients had reduced phagocytosis and oxidative burst ability compared with healthy controls. The dysfunction was most prominent in BM samples from MM, SMM, and MGUS patients. Importantly the reduced phagocytosis in MM patients was restored in patients on lenalidomide therapy. Consistently the ability of Escherichia coli stimulated oxidative burst in BM was reduced for the MM, SMM, and MGUS cohort in contrast to the healthy controls and the patients on lenalidomide treatment.ConclusionOur results show that MM patients have neutrophil dysfunction that could contribute to susceptibility for bacterial infections and that lenalidomide therapy was associated with restored PMN function.

  • Carfilzomib and dexamethasone maintenance following salvage ASCT in multiple myeloma : A randomised phase 2 trial by the Nordic Myeloma Study Group
  • 2022
  • Ingår i: European Journal of Haematology. - : John Wiley & Sons. - 0902-4441 .- 1600-0609. ; 108:1, s. 34-44

    • Objective We investigated the efficacy and safety of carfilzomib-containing induction before salvage high-dose melphalan with autologous stem-cell transplantation (salvage ASCT) and maintenance with carfilzomib and dexamethasone after salvage ASCT in multiple myeloma. Methods This randomised, open-label, phase 2 trial included patients with first relapse of multiple myeloma after upfront ASCT who were re-induced with four cycles of carfilzomib, cyclophosphamide and dexamethasone. Two months after salvage, ASCT patients were randomised to either observation or maintenance therapy with iv carfilzomib 27 -> 56 mg/sqm and p.o. dexamethasone 20 mg every second week. The study enrolled 200 patients of which 168 were randomised to either maintenance with carfilzomib and dexamethasone (n = 82) or observation (n = 86). Results Median time to progression (TTP) after randomisation was 25.1 months (22.5-NR) in the carfilzomib-dexamethasone maintenance group and 16.7 months (14.4-21.8) in the control group (HR 0.46, 95% CI 0.30-0.71; P = .0004). The most common adverse events during maintenance were thrombocytopenia, anaemia, hypertension, dyspnoea and bacterial infections. Conclusion In summary, maintenance therapy with carfilzomib and dexamethasone after salvage ASCT prolonged TTP with 8 months. The maintenance treatment was in general well-tolerated with manageable toxicity.

  • Incidence, characteristics, and outcome of solitary plasmacytoma and plasma cell leukemia. Population-based data from the Swedish Myeloma Register
  • 2017
  • Ingår i: European Journal of Haematology. - : Wiley. - 0902-4441 .- 1600-0609. ; 99:3, s. 216-222

    • Solitary plasmacytoma (SP) and plasma cell leukemia (PCL) are uncommon (3-6%) types of plasma cell disease. The risk of progression to symptomatic multiple myeloma (MM) is probably important for the outcome of SP. PCL is rare and has a dismal outcome. In this study, we report on incidence and survival in PCL/SP, and progression to MM in SP, using the prospective observational Swedish Multiple Myeloma Register designed to document all newly diagnosed plasma cell diseases in Sweden since 2008. Both solitary bone plasmacytoma (SBP) (n=124) and extramedullary plasmacytoma (EMP) (n=67) have better overall survival (OS) than MM (n=3549). Progression to MM was higher in SBP than in EMP (35% and 7% at 2 years, respectively), but this did not translate into better survival in EMP. In spite of treatment developments, the OS of primary PCL is still dismal (median of 11 months, 0% at 5 years). Hence, there is a great need for diagnostic and treatment guidelines as well as prospective studies addressing the role for alternative treatment options, such as allogeneic stem cell transplantation and monoclonal antibodies in the treatment of PCL.

  • Outcome and characteristics of non-measurable myeloma : A cohort study with population-based data from the Swedish Myeloma Registry
  • 2020
  • Ingår i: European Journal of Haematology. - : Wiley. - 0902-4441 .- 1600-0609. ; 104:5, s. 376-382

    • Objective We describe survival in patients with oligo- and non-secretory multiple myeloma (MM). We refer to the whole group as non-measurable MM and compare it with secretory MM. Methods Oligo-secretory MM was defined as M protein in serum <10 g/L and M protein in urine <200 measured as mg/day, mg/liter or mg/mmol creatinine. If patients had no M protein, they were defined as non-secretory. The groups were also subdivided by Free Light Chains (SFLC) level and ratio. Results Out of 4325 patients with symptomatic MM in the Swedish Myeloma Registry during 2008-2016 eligible for the study, 389 patients (9%) had non-measurable MM. Out of these, 253 patients (6%) had oligo-secretory and 136 (3%) had non-secretory MM. Median survival for secretory MM was 42.7 months, non-measurable MM 40.2 months, oligo-secretory MM 38.6 months, and non-secretory MM 44.6 months. Difference in overall observed survival was non-significant for all groups when compared with secretory MM. Within non-secretory MM, stem cell transplantation (SCT), 95% being auto-SCT, was significant for superior survival in multivariate analysis (HR 0.048. P = .0015). Conclusion In this population-based study, we found no difference in survival between oligo- or non-secretory MM when compared with secretory MM. SCT appears to be important also for patients with non-secretory disease.

  • Impact of 1q gains on treatment outcomes of patients with newly diagnosed multiple myeloma in a real-world Swedish population receiving modern treatment
  • 2023
  • Ingår i: European Journal of Haematology. - 0902-4441. ; 111:3, s. 391-9
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: Amplification of 1q (amp(1q); =4 1q copies) has repeatedly been reported to predict a worse outcome in multiple myeloma (MM), whereas the impact of gain of 1q (gain(1q); three 1q copies) is less clear.Methods: We investigated survival of MM in relation to amp(1q) and gain(1q) by retro-spectively analysing 346 consecutively newly diagnosed MM (NDMM) patients. Of these, 62 (18%) had amp(1q), 97 (28%) gain(1q) and 187 (54%) a normal number of 1q copies (no1q).Results: The patients with amp(1q) had a shorter median progression-free survival than those with gain(1q) or no(1q) (13.1 months, 95% confidence interval [CI] 8.2- 18.1 months vs. 36.1 months, 95% CI 23.1-49.1 months vs. 25.4 months, 95% CI 19.8-31.1 months, p = .005). The 3-year overall survival (OS) was 56% for amp(1q), 76% for gain(1q) and 80% for no1q (p = .003). In the multivariate analysis, the pres-ence of amp(1q) was independently associated with a shorter OS (hazard ratio 1.99, 95% CI 1.03-3.82, p = .039), whereas gain(1q) had no negative effect on survival.Conclusion: Our results thus suggest that amp(1q) should be considered a high-risk abnormality in NDMM and that new treatment strategies should be explored to miti-gate its negative effect on survival.

  • Epidemiology and clinical outcomes of light-chain amyloidosis in Sweden: A nationwide population-based study
  • 2023
  • Ingår i: European Journal of Haematology. - 0902-4441. ; 111:5, s. 697-705
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: This study evaluated data from six Swedish national registries to fill current evidence gaps on the epidemiology, clinical burden, and overall survival (OS) associated with light-chain (AL) amyloidosis.Methods: Patients newly diagnosed with AL amyloidosis were identified using six linked Swedish nationwide population-based registers. For each case, individuals from the general population were selected and matched with a maximum ratio of 1:5 based on age, sex, calendar year, and county.Results: 846 patients newly diagnosed with AL amyloidosis and 4227 demographically matched individuals were identified. From 2011 to 2019, annual AL amyloidosis incidence increased from 10.5 to 15.1 cases per million. At baseline, patients with AL amyloidosis had a significantly higher disease burden including higher rates of cardiac and renal failure relative to the comparison group. Among patients with AL amyloidosis, 21.5% had incident heart failure and 17.1% had incident renal failure after initial diagnosis. Median OS for patients with AL amyloidosis was 56 months versus not reached in the matched general population comparison group.Conclusion: The incidence of newly diagnosed AL amyloidosis in Sweden increased over time with AL amyloidosis being associated with a higher risk of cardiac/renal failure and all-cause mortality compared with the general population.

  • Adverse event management in patients with relapsed and refractory multiple myeloma taking pomalidomide plus low-dose dexamethasone : A pooled analysis
  • 2017
  • Ingår i: European Journal of Haematology. - : Wiley. - 0902-4441. ; 99:3, s. 199-206
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: Heavily pretreated patients with relapsed and refractory multiple myeloma are susceptible to treatment-related adverse events (AEs). Managing AEs are important to ensure patients continue therapy long enough to receive the best clinical benefit. Data from the MM-002, MM-003, and MM-010 trials were pooled to further characterize the safety profile of pomalidomide plus low-dose dexamethasone and AE management. Methods: This analysis included 1088 patients who received ≥ 2 prior therapies, including lenalidomide and bortezomib, and progressed ≤ 60 days of last therapy. Patients received 28-day cycles of pomalidomide 4 mg/day on days 1-21 and low-dose dexamethasone 40 mg (20 mg if aged > 75 years) weekly until disease progression or unacceptable toxicity. Thromboprophylaxis was required. Results: The most common grade 3/4 AEs were neutropenia (56.2%), anemia (32.3%), and thrombocytopenia (25.8%), which occurred within the first few cycles of treatment. Grade 3/4 infections occurred in 33.7% patients, of whom 13.9% had pneumonia, and 40.3% had neutropenia. Pomalidomide dose reductions or interruptions were reported in 24.2% and 66.0% of patients, respectively. AEs were managed by dose modifications and/or supportive care. Conclusions: Pomalidomide plus low-dose dexamethasone showed an acceptable safety profile, and AEs were well managed according to study protocols and established guidelines.
