A Phase II Multicenter Randomized Study Of Two Non-Myeloablative Stem Cell Transplant Strategies For Low-Grade Lymphoma And Chronic Lymphocytic Leukemia (CLL)
A Phase II Multicenter Randomized Study Of Two Non-Myeloablative Stem Cell Transplant Strategies For Low-Grade Lymphoma And Chronic Lymphocytic Leukemia (CLL)
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Radiation therapy uses high-energy x-rays to damage tumor cells. Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy. Sometimes the transplanted cells are rejected by the body's normal tissues. Cyclosporine, mycophenolate mofetil, methotrexate, and tacrolimus may prevent this from happening.
PURPOSE: Randomized phase II trial to compare the effectiveness of fludarabine plus total-body irradiation with that of combination chemotherapy followed by donor peripheral stem cell transplantation in treating patients who have relapsed non-Hodgkin's lymphoma or chronic lymphocytic leukemia.
OBJECTIVES:
OUTLINE: This is a randomized, multicenter study. Patients are stratified according to disease, age (less than 55 vs over 55), and participating transplantation center. Patients are randomized to 1 of 2 treatment arms.
At approximately day 180, patients with persistent disease, evidence of T-cell chimerism, and no GVHD may receive up to 3 donor lymphocyte infusions administered every 1-2 months.
Quality of life is assessed at baseline, 1 month, every 3 months for 1 year, and then every 6 months for 1 year.
Patients are followed at 1 month, every 3 months for 1 year, and then annually for 2 years.
PROJECTED ACCRUAL: A total of 100 patients (50 per treatment arm) will be accrued for this study.
