RELAPSE RATE AFTER CESSATION OF THERAPY IN CHILDHOOD LEUKEMIA

Abstract
Children [227] from the Nordic countries who had their antileukemic therapy stopped before Jan. 1979 were surveyed. The children were in remission when therapy was discontinued. So far 64 (23.1%) have relapsed. CNS and testicular leukemia have been a problem but CNS-prophylaxis has been in common use in the Nordic countries only since 1972-1973. Most of the patients relapsed during the 1st yr after stopping therapy; no patient relapsed later than 4 yr after cessation of therapy.
