title: Relapse rate after cessation of therapy in childhood leukemia. A follow-up report on 277 cases from the five Nordic countries.
abstract: Two hundred and seventy-seven children from the Nordic countries who had their antileukemic therapy stopped before January 1979 were surveyed. The children were in remission when therapy was discontinued. So far 64 (23.1%) have relapsed. Central nervous system (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 first year after stopping therapy, whereas no patient relapsed later than 4 years after cessation of therapy.
