Peripheral Stem Cell Transplantation in Treating Patients With Hematologic Cancer
RATIONALE: Peripheral stem cell transplantation may be able to replace immune cells that were destroyed by chemotherapy or radiation therapy used to kill tumor cells.
PURPOSE: Phase II trial to study the effectiveness of peripheral stem cell transplantation from related donors to prevent graft-versus-host disease in treating patients with hematologic cancer.
Multiple Myeloma and Plasma Cell Neoplasm
Biological: anti-thymocyte globulin
Biological: graft-versus-tumor induction therapy
Procedure: peripheral blood stem cell transplantation
Radiation: radiation therapy

OBJECTIVES: I. Evaluate the use of donor peripheral blood stem cells without graft-versus-host disease prophylaxis to maximize the probability of graft-versus-tumor effect in patients with hematologic malignancies refractory to standard chemotherapy and unlikely to be cured with high dose chemotherapy and radiotherapy.
OUTLINE: Prior to peripheral blood stem cell transplant, patients undergo preparative cytoreduction. Patients receive total body irradiation (TBI) beginning on day -5. Radiotherapy is administered in 9 doses over 3 days (3 doses per day for 3 days). Male patients with acute lymphocytic leukemia receive an additional dose of radiation to the testicles. Patients who are ineligible for TBI due to prior radiotherapy receive 2 doses of melphalan IV on day -3. All patients receive cyclophosphamide IV over 1 hour on days -2 and -1. Anti-thymocyte globulin is also administered IV over 6 hours on days -2 and -1. Approximately 24-36 hours after the last dose of cyclophosphamide, peripheral blood stem cells obtained from the HLA matched related donor are infused into the patient. Patients do not receive graft-versus-host disease prophylaxis after transplant; however, all other forms of supportive care are provided. Patients are followed for 1 year.
PROJECTED ACCRUAL: A maximum of 42 patients will be accrued for this study.
