Résumé
Date de début de l'étude : 1 septembre 1998
Date à laquelle le premier participant a commencé l'étude.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.
