By means of a questionnaire survey data from 71 patients with acute leukemia who have survived 5–12 years since the diagnosis of the disease have been collected. Thirty-six out of 53 children and 6 out of 18 adults are living and well with no evidence of leukemia more than 5 years after the diagnosis. Theoretical reasons have been considered for differences in response between these long-term survivors and the usual cases of acute leukemia.
A registry of these cases will be available at the Acute Leukemia Task Force, National Cancer Institute, Bethesda, Maryland.
These studies were supported in part by grants CA-03215 and CA-06262 from the National Cancer Institute, USPHS, and grant T-45 from the American Cancer Society.
