| Popis: | From March 1982 to September 1988, 108 patients with acute lymphoblastic leukemia (ALL) were conditioned before allogeneic (57 patients of whom 16 T-depleted) or before autologous (51 patients) bone marrow transplantation (BMT). BMT was realized in 66 patients (31 allogeneic and 35 autologous) in first complete remission (CR) and in 42 patients (26 allogeneic and 16 autologous) in second CR or greater or in relapse. All patients received high doses of alkylating agents prior to a low-dose fractionated total body irradiation of 11 Gy in 5 fractions and 5 days. Rejection and relapse rate are described in relation to the three BMT types, allogeneic non T-depleted, allogeneic T-depleted, and autologous, and to the status of the patient at the time of the transplantation. Leukemic deaths are detailed according to the same parameters. Non-leukemic deaths and complications are determined. For the allogeneic population, the 4-year disease-free survival (DFS) is 47%; it is 68.5% in first CR patients, 23.5% in second or subsequent CR patients, and 50% in T-depleted BMT. For the autologous population, 4-year DFS is 35.7%; it is 52% in first CR patients and 30% in patients in second CR or greater. The conditioning regimen appears to be efficient in terms of disease control with a low rate of complications for the non T-depleted population, transplanted in first CR, but has to be improved for the other patients. |
