Improved prognosis of acute nonlymphocytic leukemia in children: results of the 12th-ANLL protocol of Tokyo Children's Cancer Study Group.
Thirty-one children with ANLL were treated using the 12th-ANLL Protocol of the Tokyo Children's Cancer Study Group incorporating an ACMP 2-step regimen. Induction therapy consisted of two 4-day courses of adriamycin (ADR) and cytosine arabinoside (ARA-C) given with a 7-day interval. Those patients who achieved remission were given one more course as early intensification. Late intensification consisted of a 5-day course of ARA-C and one dose of ADR which was repeated until the cumulative dosage of ADR reached 465 mg/m2. After this point, treatment was divided into 2 courses. Both courses included ARA-C and one course had achlacinomycin in addition. Twenty-seven children (87%) attained remission after one or two courses of induction therapy. Kaplan-Meyer analysis revealed that the continuous complete remission rate and event-free survival were 71% and 51%, respectively, 5 years after diagnosis. Toxicity was minimum with only one death during the remission. These results are encouraging and warrant further trials.
