- Background: Standard treatment of adult Burkitt lymphoma is not defined due to the lack of randomised trials. In this situation, population-based data may represent a useful contribution in order to identify an optimal treatment strategy. Patients and methods: The aims of this study were to investigate the outcome for adult HIV-negative BL with different chemotherapy regimens, and to assess possible improvement within the time frame of the study. The study population was identified through the Swedish and Danish lymphoma registries 2000-2009. Results: A total of 258 patients were identified. Since 2000, overall survival (OS) improved significantly only for younger patients (<65 years). Intensive regimens such as the Berlin-Frankfurt-Munster, hyper-fractionated cyclophosphamide, vincristine, doxorubicin, and dexamethasone (hyper-CVAD) and cyclophosphamide, vincristine, doxorubicin, methotrexate, ifosfamide, etoposide, and cytarabine (CODOX-M/IVAC) were associated with a favourable 2-year OS of 82%, 83%, and 69%, respectively. The low-intensive CHOP/CHOEP regimens achieved a 2-year OS of 38.8%, confirming their inadequacy for the treatment of BL. In a multivariate analysis, rituximab was not significantly associated with improved OS. Conclusions: In this population-based retrospective series of adult BL, intensive chemotherapy regimens were associated with favourable outcome. The impact of the addition of rituximab remains uncertain and warrants further investigation.

- Background. For Diffuse large B-cell lymphoma (DLBCL), the International Prognostic Index is the major tool for prognostication and considers an age above 60 years as a risk factor. However, there are several indications that increasing age is associated with more biological complexity, resulting in differences in DLBCL biology depending on age. Methods. We conducted a registry-based retrospective cohort study of all Swedish DLBCL patients diagnosed 2000-2013, to evaluate the importance of age at diagnosis for survival of DLBCL patients. Results. In total, 7166 patients were included for further analysis. Survival declined for every 10-year age group and every age group above the age of 39 had a statistically decreased survival compared to the reference group of 20-29 years. In an analysis of relative survival, and in a multifactorial model adjusted for stage, ECOG performance status, serum lactate dehydrogenase and involvement of extranodal sites, each age group above age 39 had a significantly higher risk ratio (p = 0.01) compared to the reference group. Conclusion. This is one of the largest population-based studies of DLBCL published to date. In this study, age persisted as a signifi cant adverse risk factor for patients as young as 40 years, even after adjustment for other risk factors.

- Our aim was to describe a large population-based cohort of diffuse large B-cell lymphoma (DLBCL) during the last decade, evaluating possible improvement in survival and to identify subgroups in need of novel treatment strategies. The study population encompassed all patients diagnosed with DLBCL in Sweden from 2000 through 2010. Altogether 5349 patients were identified. There was no increase in incidence for females, but for males there was an estimated yearly increase in incidence by 0.019 per 10 000. When adjusted for age and gender, the improvement in overall survival for the whole group was estimated at 4.5% per year, most prominent in the age group 60-78 years, and in patients with good performance status. In this large dataset, we were able to detect a clear improvement in overall survival in DLBCL, although restricted to specific prognostic subgroups, and to identify specific disease presentations that significantly affect overall survival.
