Time trends in the incidence of acute lymphoblastic leukemia among children 1976-2002: a population-based Nordic study

Abstract

We studied the incidence of childhood acute lymphoblastic leukemia in Denmark, Finland, Norway, and Sweden during 1976-2002, on the basis of data from national cancer registries. The incidence of acute lymphoblastic leukemia increased with the calendar period until 1983, and with the birth cohort until 1980, but incidence has been stable thereafter.
