total-body irradiation, fludarabine, and peripheral stem cell transplantation in treating patients with hematologic cancer

Conditions: Leukemia; Lymphoma; Multiple Myeloma and Plasma Cell Neoplasm; Myelodysplastic Syndromes; Myelodysplastic/Myeloproliferative Diseases

Summary: rationale: radiation therapy uses high-energy x-rays to damage cancer cells. drugs used in chemotherapy use different ways to stop cancer cells from dividing so they stop growing or die. combining chemotherapy with donor peripheral stem cell transplantation may allow the doctor to give higher doses of chemotherapy drugs and kill more tumor cells. purpose: phase ii trial to study the effectiveness of combining total-body irradiation with fludarabine and donor peripheral stem cell transplantation in treating patients who have hematologic cancer.

objectives: * determine the response rate and duration of response in patients with low-risk hematologic malignancies treated with low-dose total-body irradiation (tbi) and fludarabine followed by hla-matched allogeneic stem cell transplantation followed by a slow immunosuppression taper and donor leukocyte infusions (dli). * determine the response rate and duration of response in patients with high-risk hematologic malignancies treated with low-dose tbi and fludarabine followed by hla-matched allogeneic stem cell transplantation followed by a faster immunosuppression taper and dli. * determine the incidence and extent of graft-versus-host disease, regimen-related toxicity, and engraftment in patients treated with these regimens. * assess the quality of life of patients treated with these regimens. outline: this is a multicenter study. patients are assigned to 1 of 2 groups (high-risk vs low-risk hematologic malignancy). the high-risk group includes acute myelogenous leukemia, myelodysplastic syndromes, accelerated phase chronic myelogenous leukemia (cml), second chronic phase cml, and non-hodgkin's lymphoma. the low-risk group includes hodgkin's lymphoma, first chronic phase cml, multiple myeloma, and chronic lymphocytic leukemia. patients receive fludarabine iv on days -4 to -2. patients undergo total-body irradiation on day 0 followed by allogeneic stem cell transplantation. patients also receive oral mycophenolate mofetil on days 0-28. high-risk patients receive oral cyclosporine twice daily on days -2 to day 60. patients with persistent disease, t-cell chimerism, and no graft-vs-host disease (gvhd) on day 90 receive up to 3 doses of donor leukocyte infusion (dli) over the next 4 months. low-risk patients receive oral cyclosporine twice daily on days -2 to day 150. patients with persistent disease, t-cell chimerism, and no gvhd on day 180 receive up to 3 doses of dli over the next 4 months. quality of life is assessed at baseline and at 1, 3, 6, 9, 12, 18, and 24 months. patients are followed at 1, 3, 6, 9, and 12 months and then annually for 2 years. projected accrual: a total of 120 patients (60 per group) will be accrued for this study.
