- 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.

- Purpose Systemic peripheral T-cell lymphomas (PTCLs) respond poorly to conventional therapy. To evaluate the efficacy of a dose-dense approach consolidated by up-front high-dose chemotherapy (HDT) and autologous stem-cell transplantation (ASCT) in PTCL, the Nordic Lymphoma Group (NLG) conducted a large prospective phase II study in untreated systemic PTCL. This is the final report, with a 5-year median follow-up, of the NLG-T-01 study. Patients and Methods Treatment-naive patients with PTCL age 18 to 67 years (median, 57 years) were included. Anaplastic lymphoma kinase (ALK) -positive anaplastic large-cell lymphoma (ALCL) was excluded. An induction regimen of six cycles of biweekly CHOEP (cyclophosphamide, doxorubicin, vincristine, etoposide, and prednisone) was administered (in patients age > 60 years, etoposide was omitted). If in complete or partial remission, patients proceeded to consolidation with HDT/ASCT. Results Of 166 enrolled patients, 160 had histopathologically confirmed PTCL. The majority presented with advanced-stage disease, B symptoms, and elevated serum lactate dehydrogenase. A total of 115 underwent HDT/ASCT, with 90 in complete remission at 3 months post-transplantation. Early failures occurred in 26%. Treatment-related mortality was 4%. At 60.5 months of median follow-up, 83 patients were alive. Consolidated 5-year overall and progression-free survival (PFS) were 51% (95% CI, 43% to 59%) and 44% (95% CI, 36% to 52%), respectively. Best results were obtained in ALK-negative ALCL. Conclusion Dose-dense induction followed by HDT/ASCT was well tolerated and led to long-term PFS in 44% of treatment-naive patients with PTCL. This represents an encouraging outcome, particularly considering the high median age and adverse risk profile of the study population. Therefore, dose-dense induction and HDT/ASCT are a rational up-front strategy in transplantation-eligible patients with PTCL. J Clin Oncol 30: 3093-3099.

- 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.
