The role of high-dose therapy and autologous hematopoietic stem cell transplantation for mantle cell lymphoma.
BACKGROUND
Although mantle cell lymphoma (MCL) is a distinct disease entity with well described clinical and pathological features, little information exists regarding its therapy. This paper will evaluate patients with MCL receiving either induction therapy with an anthracycline or high-dose chemotherapy and autologous hematopoietic stem cell transplantation for relapsed disease.


METHODS
The cases of 14 previously untreated patients with MCL who received an anthracycline-containing combination chemotherapy regimen on Nebraska Lymphoma Study Group protocols from 3/83 to 2/92 were reviewed. During the same time period, a different set of nine patients with recurrent MCL were referred for high-dose chemoradiotherapy and autologous stem cell rescue as salvage therapy.


RESULTS
The five year overall (OS) and failure-free (FFS) survivals from the initiation of chemotherapy for the patients receiving an induction therapy with an anthracycline containing regimen were 23% and 8%, respectively. At the time of this analysis, three of the nine transplant patients remain progression-free 7, 12, and 25 months post-transplant. Two year overall and FFS for all nine patients was 34%.


CONCLUSIONS
Longer follow-up of greater patient numbers is required to determine whether high-dose therapy can overcome the chemoresistance and increase the cure rate of MCL. Since most patients with this disease have minimal chance of cure with standard chemotherapy, the optimal timing for high dose therapy may be as part of front-line treatment. Further clinical trials are required to investigate the potential benefits of high-dose therapy for patients with MCL.
