    • In the present study, we investigate the outcome of 109 Danish and 123 Swedish patients with nodal PTCL in first complete remission (CR), and examine the impact of imaging-based follow-up (FU) strategies. The patients were selected by the following criteria: (a) newly diagnosed nodal PTCL from 2007 to 2012, (b) age ≥18 years, and (c) CR after CHOP or CHOEP therapy. FU guidelines in Sweden included symptom assessment, clinical examinations and blood tests at 3–4-month intervals for 2 years. FU strategies in Denmark was similar but included routine imaging, usually every 6 months for 2 years. Patients had fully comparable characteristics. Overall survival (OS) estimates for patients in CR were similar for all patients (p =.6) and in PTCL subtypes. In multivariate analysis, country of follow-up had no impact on OS. However, despite continuous CR for ≥2 years, the OS of PTCL remained inferior to a matched general population.

  • The addition of etoposide to CHOP is associated with improved outcome in ALK+ adult anaplastic large cell lymphoma : A Nordic Lymphoma Group study
  • 2017
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048. ; 178:5, s. 739-746
  • Tidskriftsartikel (refereegranskat)abstract
    • Anaplastic large cell lymphomas (ALCLs) are rare CD30+ peripheral T-cell lymphomas (PTCLs) classified according to the expression of the anaplastic lymphoma kinase (ALK+) protein or not (ALK-). We have analysed the outcome and risk factors for survival in a population-based bi-national cohort of patients with systemic ALK+ ALCL. A total of 122 adult (≥18 years) patients diagnosed with ALK+ ALCL between 2000 and 2010 were identified from the Danish and Swedish lymphoma registries, representing 0·4% of all lymphomas. The median age of the cohort was 40 years (range 18-85). The 5-year overall survival and progression-free survival (PFS) was 78% and 64%, respectively. Age was strongly associated with outcome, and only bone marrow (BM) involvement was independently associated with poorer PFS in multivariate analysis (Hazard Ratio [HR] = 8·57, P < 0·001). Age stratification of the patients demonstrated an association between treatment with CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, prednisolone) and improved overall survival for patients aged 41-65 years, even when adjusted for risk factors (HR = 0·38, P = 0·047). Our results suggest that the addition of etoposide to CHOP (cyclophosphamide, doxorubicin, vincristine, prednisolone) in the treatment for ALK+ ALCL seems reasonable in this age group.

  • Phase II trial of zanolimumab (HuMax-CD4) in relapsed or refractory non-cutaneous peripheral T cell lymphoma
  • 2010
  • Ingår i: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 150:5, s. 565-573
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Valproate in combination with rituximab and CHOP as first-line therapy in diffuse large B-cell lymphoma (VALFRID)
  • 2018
  • Ingår i: Blood Advances. - : American Society of Hematology. - 2473-9529 .- 2473-9537. ; 2:12, s. 1386-1392
  • Tidskriftsartikel (refereegranskat)abstract
    • The aims of the present study were to establish the maximally tolerated dose (MTD) of the histone deacetylase inhibitor valproate together with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) in patients with diffuse large B-cell lymphoma (DLBCL). A phase 1 dose escalation study of valproate together with R-CHOP followed by a dose expansion study using the established MTD of valproate was performed. MTD of valproate together with R-CHOP was established at 60 mg/kg per day, as higher doses resulted in auditory adverse events (AEs). In the study population, 2-year progression-free survival was 84.7% (95% confidence interval [CI], 73.2%-98%). The 2-year overall survival (OS) was 96.8% (n = 31; 95% CI, 90.8%-100%). These data were compared with 2 risk-factor matched populations of R-CHOP-treated patients from the Swedish Lymphoma Registry (cohort A, n = 330 and B, n = 165). As compared with the matched cohorts, we observed a statistically significant (P = .034 and 0.028, respectively) beneficial effect of the addition of valproate to R-CHOP on the OS in the studied population. In conclusion, addition of valproate to R-CHOP is a feasible strategy in first-line treatment of DLBCL. The proposed phase 2 dose is 60 mg/kg per day together with prednisone. Auditory AEs were unexpected and warrant close monitoring. Our findings suggest that drugs that target histone deacetylation may add benefit and are tolerable when combined with standard R-CHOP in DLBCL. The phase 1 trial was registered at www.clinicaltrials.gov as #NCT01622439.

  • Central nervous system relapse in peripheral T-cell lymphomas: A Swedish lymphoma registry study.
  • 2015
  • Ingår i: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 126:1, s. 36-41

    • Central Nervous System (CNS) relapse in non-Hodgkin lymphomas (NHL) carries a very poor prognosis. Risk factors and outcome have been studied in aggressive B-cell lymphomas but very little is known about the risk in peripheral T-cell lymphoma (PTCL). We aimed at analyzing risk factors for CNS involvement at first relapse or progression, and the outcome of these patients, in a large population-based cohort of PTCL patients. Twenty-eight out of 625 patients (4.5%) developed CNS disease over time. In multivariable analysis disease characteristics at diagnosis independently associated with an increased risk of later CNS involvement were involvement of >1 extranodal site (Hazard Ratio [HR] 2.60, 95% Confidence Interval [95% CI] 1.07-6.29, p=0.035), skin (HR 3.51, 95% CI 1.26-9.74, p=0.016) and gastrointestinal involvement (HR 3.06, 95% CI 1.30-7.18, p=0.010). The outcome of relapsed/refractory patients was very poor and CNS involvement was not associated with a significantly worse outcome compared to relapsed/refractory patients without CNS involvement in multivariable analysis (HR 1.6, 95% CI 0.96-2.6, p=0.074). The results from the present study indicate that CNS relapse in PTCL occurs at a frequency similar to what is seen in aggressive B-cell lymphomas, but the poor outcomes in relapse are largely driven by systemic rather than CNS disease.

  • Impact of comorbidity on survival in peripheral T-cell lymphomas : A Swedish Lymphoma Registry study
  • 2018
  • Ingår i: Hematological Oncology. - : Wiley. - 0278-0232. ; 36:1, s. 159-165
  • Tidskriftsartikel (refereegranskat)abstract
    • Comorbidity impacts survival in B-cell lymphoma patients, but the influence in peripheral T-cell lymphomas (PTCLs) has been little studied. To investigate the impact of comorbidity on outcome in PTCL, we identified adult patients with newly diagnosed PTCL from 2000 to 2009 in the Swedish Lymphoma Registry. Data on comorbidity at diagnosis were retrospectively collected according to the Charlson Comorbidity Index (CCI). Comorbid conditions were present in 263 out of 694 (38%) patients. A CCI score of ≥2 was associated with inferior overall survival (OS) (hazard ratio [HR] 1.63, P < .001) and progression-free survival (HR 1.54, P < .001) in multivariate analysis. In patients undergoing front-line autologous stem cell transplantation (auto SCT), CCI >0 was associated with inferior OS (HR 2.40, P = .013). Chemotherapy regimens were classified as curative or low-intensity treatments. Among patients aged ≥75 years (n = 214), low-intensity and curative treatment groups had similar OS (HR 0.8, P = .6), also when adjusted for CCI. In summary, our results demonstrate CCI to be independently associated with survival in PTCLs. Even limited comorbidity impacted survival after front-line auto SCT, which needs to be considered in treatment decisions. Intensive anthracycline-based chemotherapy in elderly PTCL patients might be of limited benefit.

  • Real world data on prognostic factors and treatment in peripheral T-cell lymphomas: a study from the Swedish Lymphoma Registry.
  • 2014
  • Ingår i: Blood. - : American Society of Hematology. - 1528-0020 .- 0006-4971. ; 124:10, s. 1570-1577

    • Peripheral T-cell Lymphomas (PTCLs) are rare lymphomas with mostly poor outcome with current treatment. Addition of etoposide to CHOP and up-front consolidation with autologous stem cell transplantation (autoSCT) have shown promising results, but have never been tested in randomized trials. As a complement to retrospective analyses of clinical trials, we aimed at analyzing prognostic factors and outcome in an unselected, population-based cohort. Through the Swedish Lymphoma Registry we identified 755 PTCL patients diagnosed during a 10-year period. In addition to International Prognostic Index (IPI) factors, male gender was associated with an adverse overall survival (OS) (HR 1.28, p=0.011) and progression-free survival (PFS) (HR 1.26, p=0.014). In an intention-to-treat analysis in 252 nodal PTCL and EATL patients (excluding ALK-positive ALCL), up-front autoSCT was associated with a superior OS (HR 0.58, p=0.004) and PFS (HR 0.56, p=0.002) compared to patients treated without autoSCT. Addition of etoposide to CHOP resulted in superior PFS in patients up to 60 years (HR 0.49, p=0.008). This study is the largest population-based PTCL cohort reported so far and provides important information on outcome in PTCL outside the setting of clinical trials.

  • Treatment outcome in T-cell lymphoblastic lymphoma in adults : a population-based study from the Swedish Lymphoma Registry
  • 2014
  • Ingår i: Acta Oncologica. - 0284-186X .- 1651-226X. ; 53:7, s. 927-934
  • Tidskriftsartikel (refereegranskat)abstract
    • Background. T-cell lymphoblastic lymphoma (T-LBL) is a rare neoplasm of precursor lymphoblast origin, for which there is no standard treatment for adults. Results of current treatment strategies in selected populations do exist but are largely unreported for unselected series. Here, we aimed to investigate treatment outcome in a population-based cohort. Material and methods. Patients were identified through the Swedish Lymphoma Registry and data was retrospectively collected for all adult (>= 18 years) Swedish T-LBL patients diagnosed during 2000-2009. Results. A total of 39 patients with median age 40 years (range 18-78) were identified with females being significantly older than males (median age 66 vs. 37, p = 0.027). The five-year overall survival for all patients was 42%. Female gender was associated with shorter survival also when adjusted for treatment strategy and age [hazard ratio (HR) 4.29; p = 0.002]. Thirty patients received intensive chemotherapy, otherwise used for treatment of acute lymphoblastic leukemia (ALL), which resulted in an overall response rate of 97% and a five-year progression-free survival (PFS) of 49%. In this group only CNS involvement at diagnosis predicted shorter PFS (HR 13.3; p = 0.03). Among patients treated with hyper-CVAD the addition of mediastinal irradiation resulted in prolonged time to progression compared to patients receiving only chemotherapy (p = 0.047). The major reason for treatment failure was relapse and in this series 18-fluoro-deoxyglucose positron emission tomography (PET) did not predict this risk. Conclusion. This population-based study indicates that all fit T-LBL patients should be considered for intensive treatment. Our results also suggest a beneficial effect of mediastinal irradiation in combination with hyper-CVAD treatment. Relapsing patients have a dismal outcome irrespective of salvage treatment.
