title: Cessation of therapy in childhood leukemia. A survey of 160 cases from the Nordic Countries.
abstract: A survey is presented of 160 children from the Nordic countries who had their antileukemic therapy discontinued prior to November 1976. Twenty-seven of the 160 cases (17%) had suffered a relapse before May, 1977. Sixty-nine cases had their therapy stopped in the first ten months of 1976. All cases have been reported as acute lymphocytic leukemia. Different types of therapy schedules have been used. Thirty-five cases in sustained remission for more than 3 years without cessation of therapy are also included in the report, seventeen of whom had relapsed while still on therapy. Central nervous system or testicular relapse occurred in 21 of the total 44 cases who relapsed after three or more years of continuous remission, and whether they were on therapy or not.
