- Non-germinal center (non-GC) phenotype is an adverse prognostic factor in chemotherapy (CT)-treated diffuse large B-cell lymphoma (DLBCL) patients. To determine how high-dose therapy (HDT) supported with auto-SCT as first line therapy influences GC-associated outcome in young high-risk DLBCL patients GC and non-GC phenotypes were determined immunohistochemically from 63 patients. Of these, 29 primary high-risk DLBCL patients were treated with auto-SCT, whereas 34 CT-treated patients served as a control group. Consistent with previous studies, non-GC phenotype was associated with adverse outcome in CT-treated high-risk patients. In contrast, immunohistochemical classification by cell of origin did not associate with survival after auto-SCT. When the impact of treatment on the predictive value of cell of origin was analyzed, the non-GC patients, who received HDT, had a better failure-free survival (FFS) and overall survival (OS) than the patients treated with CT alone. In multivariate analyses, both age-adjusted International Prognostic Index (aaIPI) and treatment were independent prognostic factors for FFS and OS. For the patients with GC phenotype, the influence of auto-SCT on survival was not significant. The data imply that auto-SCT can overcome the adverse prognostic impact of the non-GC phenotype in patients with high-risk DLBCL and warrant additional prospective studies.

- Objective: The aim of the first Nordic mantle cell lymphoma (MCL) protocol was to study the clinical significance of an augmented CHOP induction chemotherapy followed by high-dose chemotherapy and autologous stem cell transplantation (ASCT) and to examine the prognostic significance of stem cell contamination rates in newly diagnosed patients with MCL. Patients and methods: Forty-one newly diagnosed patients below 66 yr were enrolled and given three series of an augmented CHOP regimen. Responders underwent stem cell mobilization with a fourth course of CHOP, stem cell harvest and ASCT. Stem cell purging was optional in the protocol and followed the routine of each participating centre. The number of tumour cells in the reinfused autografts was estimated by flow cytometry or quantitative PCR. Results: Induction therapy led to complete remission (CR) in 11 of 41 patients (27%), partial remission (PR) in 20 of 41 patients (49%) and no response in nine patients (22%), whereas one patient was not evaluable. Twenty-seven of the 31 responders underwent ASCT and 24 achieved or maintained a CR. The overall and failure-free 4-yr survival on intention-to-treat basis were 51% and 15%, respectively. Among the transplanted patients, a significantly increased failure-free (P < 0.03) and overall survival (P = 0.03) was noted among patients transplanted in CR compared with PR, respectively. By contrast, reinfusion of highly variable numbers of tumour cells with the autografts (range 0.71-80 x 10(6) tumour cells), did not affect outcome. Conclusion: In MCL, an important strategy to improve the outcome will be to intensify the induction chemotherapy.

- In recent decades, the prognosis of Mantle Cell Lymphoma (MCL) has been significantly improved by intensified first-line regimens containing cytarabine, rituximab and consolidation with high-dose-therapy and autologous stem cell transplantation. One such strategy is the Nordic MCL2 regimen, developed by the Nordic Lymphoma Group. We here present the 15-year updated results of the Nordic MCL2 study after a median follow-up of 114years: For all patients on an intent-to-treat basis, the median overall and progression-free survival was 127 and 85years, respectively. The MCL International Prognostic Index (MIPI), biological MIPI, including Ki67 expression (MIPI-B) and the MIPI-B including mIR-18b expression (MIPI-B-miR), in particular, significantly divided patients into distinct risk groups. Despite very long response durations of the low and intermediate risk groups, we observed a continuous pattern of relapse and the survival curves never reached a plateau. In conclusion, despite half of the patients being still alive and 40% in first remission after more than 12years, we still see an excess disease-related mortality, even among patients experiencing long remissions. Even though we consider the Nordic regimen as a very good choice of regimen, we recommend inclusion in prospective studies to explore the benefit of novel agents in the frontline treatment of MCL.
