Phase II Study of Multimodality Therapy in Mantle Cell Lymphoma

OBJECTIVES:

• Determine the toxicities of combination chemotherapy followed by allogeneic or autologous bone marrow transplantation or peripheral blood stem cell transplantation and/or interferon and interleukin therapy in patients with refractory or stage III or IV mantle cell lymphoma.
• Determine the complete response rate in these patients after these treatments.
• Evaluate the prognostic factors in this patient population.

OUTLINE: This is a multicenter study.

Patients receive induction chemotherapy consisting of cyclophosphamide IV, doxorubicin IV, and teniposide IV over 2 hours on day 1, oral prednisone on days 1-5, vincristine IV and methotrexate IV over 2 hours on day 21, cytarabine IV over 2 hours every 12 hours for a total of 2 doses on day 22, and oral leucovorin calcium every 6 hours beginning on day 22 and continuing until methotrexate levels recover. Treatment repeats every 42 days for 2 courses. Patients achieving complete response or partial response receive an additional course of induction therapy. Patients achieving maximal response following 2 courses of induction chemotherapy undergo transplantation.

Patients under 50 years with an HLA matched donor undergo allogeneic bone marrow transplantation (BMT). Patients receive busulfan IV every 6 hours for a total of 14 doses beginning on day -8 and continuing for 3.5 days. At 24 hours following the last dose of busulfan, patients receive cyclophosphamide IV over 2 hours daily for 2 days. Patients receive allogeneic bone marrow infusion on day 0.
