Abstract
During the past 10 years, 86 patients 30 to 54 years of age with hematologic malignancies were prepared with high-dose radiochemotherapy and received histocompatible bone marrow grafts. Thirty-four of these patients are surviving for 4 months to 9 years (median, 26 months) following marrow transplantation and 32 of them are in continuing complete remission (CR). Disease-free survival is 44% for 37 patietns who were in first remission of acute leukemia or in the chronic phase of chronic granulocytic leukemia (CGL), 23% for 39 patients whose leukemia had relapsed at least once before transplantation or who had advanced stages of CGL, and 60% for ten patients who had hematologic malignancies other than leukemia. The median age of the surviving 34 patients is 36 years (range, 30 to 43 years). The incidence of moderate to severe acute graft-v-host disease (GVHD) was 48% and of chronic GVHD, 26%. The major causes of failure were interstitial pneumonia in 31 patients (24 of whom had antecedent acute GVHD) and recurrent leukemia in 12 patiens (11 of whom had either never entered a CR or had relapsed at least once with acute leukemia or had progressive CGL before transplantation). Our data warrant further prospective studies in patients with hematologic malignancies who are older than 30 years.
