✦ Synopsis

Abstract

Three groups of children with acute lymphoblastic leukemia (ALL) were treated with intermittent cyclophosphamide, vincristine, cytosine arabinoside, and prednisone (COAP). Group A (no prior relapse) and Group B (prior single‐agent relapse) received COAP after 12 months on another chemotherapy regimen. Children in Group C (prior relapse on multiagent regimens) received COAP following A‐COAP (asparaginase plus COAP) reinduction. Median disease‐free survival after beginning COAP was not reached for Group A, but was only 7 months for Groups B and C. As of November 1976, there were 8 of 15 Group A patients, 1 of 12 Group B patients, and 1 of 28 Group C patients who had remained disease‐free from 38 to 60 (median 54.5) months and were off chemotherapy. COAP has activity in childhood ALL. However, effectiveness in markedly diminished in patients with prior bone marrow relapse.

## Abstract Although the majority of children with acute lymphoblastic leukemia (ALL) can electively stop treatment after 21/2–5 years of continuous disease‐free remission, 20–25% of those patients relapse after discontinuation of therapy.

## Abstract Eleven patients with acute lymphocytic leukemia in relapse were treated with L‐asparaginase and cytosine arabinoside (1‐β‐D‐arabinofuranosylcytosine) in induction therapy and the same drugs plus cyclophosphamide in maintenance therapy. Three patients had complete remissions lasting 6, 1
