Abstract

The Italian Registry of Off-Therapy patients after childhood tumors now includes 760 subjects with acute lymphoblastic leukemia. These patients were all removed from treatment by December 31, 1981, and were followed in 35 different institutions. All the children have received multiple-drug treatment, combined, in 79.7% of the cases, with cranial irradiation. Thirty-nine (5%) experienced a relapse before treatment suspension. Total duration of antileukemic therapy ranges between 18 and 131 months (median, 38). At the last updating (December 31, 1981), 699 subjects were alive, 6 were lost to follow-up, and 55 had died. Life-table analysis shows that 90.8% were alive and 77% were alive in continuous complete remission at 36 months, whereas at 66 months, the cumulative proportions were 88% and 75.5%, respectively. One hundred thirty-six of 760 relapses after therapy suspension were reported: 83 male patients and 53 in female patients (P <0.01). The longest interval between relapse and treatment suspension was 64 months. Six of 55 died in continuous complete remission 3 to 44 months after treatment suspension. Five births of apparently normal babies to female patients have been reported. A general outline of the project and the future program are given.
