[Treatment of 71 adult acute lymphoblastic leukemia].
From 1975 to 1989, 71 acute lymphoblastic leukemia patients aged 15 to 81 years (median 46 years) were treated at Jichi Medical School. Fifty-eight patients (81.7%) achieved complete remission (CR). Median CR duration was 219 days, and the probability of being in continuous CR at 3 years was 8.9%. Median survival was 462 days, and the probabilities of being alive at 3 and 5 years were 19.8% and 7.3%, respectively. The new regimen introduced from 1987 consisted of remission induction with L-asparaginase, daunomycin, vincristine and prednisolone, followed by intensive consolidation and maintenance. However, the treatment failed to improve outcome. The factor unfavorable for achieving early CR after first-line treatment regimen was the presence of myeloid antigen, and that for achieving final CR after second-line treatment regimen was advanced age. The factors unfavorable for remission duration were high leukocyte count and late CR. Those unfavorable for survival were advanced age and elevated blood urea nitrogen. Further improvement in the design of new protocols which include the use of several cytokines and autologous bone marrow transplantation may result in prolonged disease-free survival.
