[Comparative evaluation of combined chemotherapeutic regimens in acute non-lymphocytic leukemia]

We analysed the effects of three different regimens for first induction therapy with 50 cases of acute nonlymphocytic leukemia in adults and reported the results of combination therapy including aclacinomycin for reinduction therapy. Results obtained were as follows: The regimens of DCMP 2 step and Cc, P were superior to DCMP in remission rate (78%, 78% and 41%), median duration of CR (8.3 months, 5.0 months and 3.5 months) and survival time (6.5 months, 11.5 months and 2 months). Cc, P regimens obtained favorable CR rate in elderly patients over 50 years of age. (Cc, P: 100%, others: 40-50%) No significant difference in survival time was observed in patients who attained CR by three different regimens. In patients treated with combination therapy including aclacinomycin, the CR rate was 89% in the 9 previously treated patients (5 relapse cases and 4 refractory leukemias): All of these patients had previously been treated with DCMP 2 step or BHAC-DMP. Daunomycin (D), Cytosine Arabinoside (C), 6-Mercaptopurine (M) and Prednisolone (P) (DCMP), DCMP 2 step and Cyclocytidine (Cc) P.
