- There is consensus that young patients with mantle cell lymphoma (MCL) should receive intensive immunochemotherapy regimens, but optimal treatment of elderly patients as well for as patients with limited or indolent disease is not defined. Our aim was to evaluate and compare outcome in relation to prognostic factors and first-line treatment in patients with MCL in a population-based data set. Data were collected from the Swedish and Danish Lymphoma Registries from the period of 2000-2011. A total of 1389 patients were diagnosed with MCL. During this period, age-standardized incidence MCL increased, most prominently among males. Furthermore, male gender was associated with inferior overall survival (OS) in multivariate analysis (HR 1.36; p=0.002). Forty-three (3.6%) patients with stage I-II disease received radiotherapy with curative intent, showing a 3 year OS of 93%. Twenty-nine (2.4%) patients followed a watch-and-wait approach and showed a 3 year OS of 79.8%. Among patients receiving systemic treatment, rituximab (n=766; HR 0.66; p=0.001) and autologous stem cell transplant (ASCT) (n=273; HR 0.55; p=0.004) were independently associated with improved overall survival in multivariate analysis. Hence, by a population-based approach, we were able to provide novel data on prognostic factors and primary treatment of MCL, applicable to routine clinical practice.

- 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.

The Mantle Cell Lymphoma International Prognostic Index (MIPI) is superior to the International Prognostic Index (IPI) in predicting survival following intensive first-line immunochemotherapy and autologous stem cell transplantation (ASCT)

- Mantle cell lymphoma (MCL) has a heterogeneous clinical course. The recently proposed Mantle Cell Lymphoma International Prognostic Index (MIPI) predicted the survival of MCL better than the International Prognostic Index in MCL patients treated with conventional chemotherapy, but its validity in MCL treated with more intensive immunochemotherapy has been questioned. Applied here to 158 patients of the Nordic MCL2 trial of first-line intensive immunochemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation, the MIPI and the simplified MIPI (s-MIPI) predicted survival significantly better (P < .001) than the International Prognostic Index (P > .004). Both the MIPI and the s-MIPI mainly identified 2 risk groups, low and intermediate versus high risk, with the more easily applied s-MIPI being just as powerful as the MIPI. The MIPI(B) (biological), incorporating Ki-67 expression, identified almost half of the patients as high risk. We suggest that also a simplified MIPI(B) is feasible.

Nordic MCL-3 study : 90Y-ibritumomab-tiuxetan added to BEAM/C in non-CR patients before transplant in mantle cell lymphoma

- The main objective of the MCL3 study was to improve outcome for patients not in CR before transplant by adding (90)Y-ibritumomab-tiuxetan (Zevalin) to the high-dose regimen. 160 consecutive, untreated stage II-IV MCL patients < 66 years received rituximab (R)- maxi-CHOP alternating with R-high-dose Ara-C (6 cycles total), followed by high-dose BEAM or BEAC and autologous stem cell transplantation 2005-2009. Zevalin (0.4 mCi/kg) was given to responders in only CRu/PR prior to high-dose therapy. The overall response rate (ORR) pre-transplant was 97%. After a median follow-up of 4.4 years the outcome did not differ from that of the historic control, the MCL2 trial with the same treatment except for Zevalin. Overall (OS), event free (EFS), and progression-free survival (PFS) at 4 years were 78, 62 and 71%, respectively. For patients in CRu/PR before transplant who received Zevalin duration of response was shorter than in the CR group. Inferior PFS, EFS- and OS were predicted by PET-positivity pre-transplant and detectable minimal residual disease (MRD) before and after transplant. In conclusion, a positive PET prior to transplant and MRD are strong predictors of outcome. Late intensification with Zevalin may be too late to improve the outcome of patients not in CR before transplant.

- In a population-based study on cobalamin status and incident fractures in elderly men (n=790) with an average follow-up of 5.9years, we found that low levels of metabolically active and total cobalamins predict incident fractures, independently of body mass index (BMI), bone mineral density (BMD), plasma total homocysteine (tHcy), and cystatin C.
