title: Hematopoietic stem cell transplantation in mantle cell lymphoma.
abstract: BACKGROUND
  Patients with mantle cell lymphoma (MCL) have in general, lower response rates and overall survival (OS) than those with other B-cell non-Hodgkin's lymphomas. The role of hematopoietic stem cell transplantation (HSCT) in MCL is unclear. Hence we decided to study the clinical course of patients who received autologous and allogeneic HSCT for MCL.
  
  
  METHODS
  Ninety-seven patients, (80 patients-autologous; 17 patients-allogeneic) who received a HSCT for mantle cell lymphoma were included in the study.
  
  
  RESULTS
  The complete response rates at day 100 between the two groups were similar (73% vs. 62%). Day-100 mortality was higher in the allogeneic HSCT group (19% vs. 0%) (P < 0.01). The estimated 5-year relapse rates, 5-year event-free survival (EFS) and 5-year OS among the allogeneic HSCT patients were 21%, 44% and 49%, respectively, similar to 56%, 39% and 47% in the autologous group. Ten patients received HyperCVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone + high-dose methotrexate and cytarabine) +/- rituximab prior to transplant. There have been no relapses or deaths amongst these patients at a median follow-up of 16 months.
  
  
  CONCLUSIONS
  Patients treated with allogeneic HSCT had a lower relapse rate, but similar EFS and OS to autologous HSCT. Treatment of MCL with HyperCVAD +/- rituximab followed by HSCT seems promising.
