- Follicular lymphoma (FL) is a heterogeneous disease; therefore, reliable prognostic tools are needed to plan treatment strategies. The FL International Prognostic Index (FLIPI) was developed before the rituximab era, while the PRIMA-PI was built on rituximab chemotherapy. Our objective was to evaluate these two prognostic tools in a cohort of 291 patients with FL treated in two prospective randomised Nordic Lymphoma Group trials with rituximab +/- interferon. All patients had symptomatic/progressive disease and were previously untreated. The PRIMA-PI was prognostic for both time to treatment failure (TTF) and overall survival (OS) (log-rank P = 0 center dot 003 and P < 0 center dot 001, respectively). The PRIMA-PI high-risk identified a small group of patients with a very short TTF and OS compared to the low-risk group, with a hazard ratio (HR) of 1 center dot 90 (95% confidence interval [CI] 1 center dot 30-2 center dot 78, P = 0 center dot 001) and HR of 3 center dot 19 (95% CI 1 center dot 75-5 center dot 83, P < 0 center dot 001), respectively. The FLIPI risk groups were prognostic only for OS (log-rank P = 0 center dot 018). The simplified PRIMA-PI was valid in our FL cohort with first-line rituximab-containing chemo-free therapy and shows an improved risk stratification compared to the FLIPI, especially in patients aged >60 years. Patients in the PRIMA-PI high-risk group should be considered for alternative therapies.

- High pre-transplantation serum ferritin levels have been reported to be associated with impaired survival post-transplantation in patients with acute myeloid leukemia or myelodysplastic syndrome. We performed a retrospective study of 309 patients who underwent allogeneic hematopoietic stem cell transplantation at two transplantation centers. The aim was to determine the effect of pre-transplantation hyperferritinemia on survival, graft versus host disease, and relapse. In both univariate and multivariate analysis, elevated ferritin levels were significantly associated with shorter overall and relapse-free survival times and increased relapse rate, but lower risk of chronic graft versus host disease. Elevated ferritin levels were not associated with non-relapse mortality. We hypothesize that ferritin may exert an immunosuppressive effect, reducing graft versus host disease and graft versus leukemia effects, resulting in increased risk of relapse and impaired survival.

- Young patients with diffuse large B-cell lymphoma (DLBCL) are variably treated with rituximab combined with cyclophosphamide-doxorubicin-vincristine-prednisone (R-CHOP), CHOP-etoposide (R-CHOEP), and anthracycline-based regimens with the addition of high-dose cytarabine/methotrexate (R-HDA/M). Using the nationwide, population-based Swedish Lymphoma Registry, we evaluated outcome, by treatment and Healthcare Region, in all 751 DLBCL patients aged 60years without central nervous involvement, diagnosed in Sweden between 2007 and 2012. Overall survival was estimated using multivariate Cox analysis. In patients with age-adjusted international prognostic index (aaIPI)2, the 5-year overall survival (OS) was 70%, 76% and 85% after R-CHOP, R-CHOEP and R-HDA/M, respectively (P=0002); the corresponding estimates were 40%, 55%, and 92% in aaIPI=3 (P=0014). There were large therapeutic differences between Sweden's six Healthcare Regions for aaIPI2: three were Moderate (more R-CHOP) and three Intensive (more R-CHOEP and R-HDA/M). Patients with aaIPI2 who were treated in the Intensive Regions, showed better OS (P<000005), particularly those with aaIPI=3 (5-year OS, 62% vs. 30%; P<000005). There were no regional differences in therapy or survival in patients with aaIPI<2. We conclude that in younger high-risk patients, survival appears superior after more intensive therapy than R-CHOP.

Clinical and biological impact of SAMHD1 expression in mantle cell lymphoma

- SAMHD1 is a deoxynucleoside triphosphate triphosphohydrolase (dNTPase) that restricts viral replication in infected cells and limits the sensitivity to cytarabine by hydrolysing its active metabolite, as recently shown in acute myeloid leukemia. Cytarabine is an essential component in the Nordic mantle cell lymphoma protocols (MCL2 and MCL3) for induction and high-dose chemotherapy treatment before autologous stem cell transplantation for younger patients with mantle cell lymphoma (MCL). We here investigated the expression of SAMHD1 in a population-based cohort of MCL (N = 150). SAMHD1 was highly variably expressed in MCL (range, 0.4% to 100% of positive tumor cells). Cases with blastoid/pleomorphic morphology had higher SAMHD1 expression (P = 0.028) and SAMHD1 was also correlated to tumor cell proliferation (P = 0.016). SAMHD1 expression showed moderate correlation to the expression of the transcriptional regulator SOX11 (P = 0.036) but genetic silencing of SOX11 and SAMHD1 by siRNA in MCL cell lines did not suggest mutual regulation. We hypothesized that expression of SAMHD1 could predict short time to progression in patients treated with Cytarabine as part of high-dose chemotherapy. Despite the correlation with known biological adverse prognostic factors, neither low or high SAMHD1 expression correlated to PFS or OS in patients treated according to the Nordic MCL2 or MCL3 protocols (N = 158).

- Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is an indolent CD20(+) lymphoma. Its scarcity has made clinical trials difficult and there is no consensus on first-line treatment. We conducted a population-based study of all patients diagnosed with NLPHL in Sweden between 2000 and 2014 (N=158; 41 women and 117 men), focusing on clinical features, therapy and overall survival. The median female and male age was 59 and 44years, respectively (P=0002). In early-stage disease, there was little mortality and no survival differences between therapies. In patients with advanced-stage disease, mortality was relatively high in patients who did not receive first-line rituximab but absent in those who did (10-year survival, 55% vs. 100%; P=0033); there were no imbalances of prognostic factors between those two groups. In advanced stages, first-line rituximab use increased markedly between 2000-2004 and 2005-2014 (7% vs. 67%; P<000005), as did 10-year survival, 53% vs. 72% (multivariate P=0027). Although all patients were diagnosed in the 2000s, this is the longest-followed (and largest) population-based cohort. We report a hitherto unreported 15-year median age difference between sexes, increasing rituximab use and improved survival.
