Short-term therapy for acute myelogenous leukemia.
Since 1978, 187 patients (age range, 15 to 59, median 44 years) have received short-term chemotherapy as part of three sequential open studies (B-IX, X, Xb) or a randomized clinical trial (B-XI). An intended six cycles of Adriamycin (ADR) (doxorubicin; Adria Laboratories, Columbus, OH), cytarabine (ara-C), and thioguanine (TG) were administered with as short an intercycle time as possible. No further therapy was administered. Complete remission (CR) was achieved in 118 of 187 patients (63%). On univariate and multivariate analyses achievement of CR correlated adversely with a low serum albumin at presentation and an antecedent marrow disorder. Forty-five patients continue in first remission between 15 months and 8 1/2 years, no relapses being seen after 3 1/2 years (median follow-up, 3 1/2 years). The median duration of remission was 1 year. M3 morphology, a blast count less than 100 x 10(9)/L, and absence of hepatosplenomegaly correlated favorably with remission duration. There was no difference in duration of remission between patients receiving 3, 4, 5, or 6 cycles. The best results overall were achieved in patients under the age of 40, with 43% projected to remain free of disease at 5 years. Fifty patients remain alive between 17 months and 9 years, the predicted actuarial survival being 25% at 5 years.
