title: Marrow transplantation for the treatment of chronic myelogenous leukemia.
abstract: One hundred ninety-eight patients with chronic myelogenous leukemia received marrow transplants after intensive chemotherapy and total body irradiation. Multivariate analysis showed disease status at time of transplantation to be the most powerful predictor of survival. The probability of long-term survival for allogeneic graft recipients was 49% for 67 patients in the first chronic phase, 58% for 12 in the second chronic phase, 15% for 46 in the accelerated phase, and 14% for 42 in the blastic phase. The major cause of death was interstitial pneumonia for patients in the chronic phase, and relapse for those in the blastic or accelerated phases. Factors favoring survival were early transplantation, age less than 30 years, and absence of severe graft-versus-host disease. Splenectomy or spleen size did not influence survival. For recipients of syngeneic grafts survival probability was 87% for 16 patients in the chronic phase, 27% for 7 in the accelerated phase, and 12% for 8 in the blastic phase. Of the 198 patients, 71 are alive without Philadelphia chromosomes 1 to 9 years after receiving their graft. All but 4 long-term disease-free survivors have Karnofsky performance scores of 80% or better.
