Abstract
During 1967-1981, the population-based Childhood (ages 0-14 years) Cancer Registry of the Province of Torino has recorded 1057 resident children with incident cancer. The life status of each child has been ascertained as of December 31, 1983. Sex- and age-specific incidence rates have been stable throughout the period. Annual mortality rates (per million) from leukemias (all types) decreased from 34.0 in 1967-69 to 19.4 in 1979-81. Correspondingly, the survival percentage cumulative of leukemic children at 3 years after diagnosis increased from 16 for children diagnosed in 1967-69 to 57 for those diagnosed in 1979-81. For other cancer types, no increases or debatable decreases in mortality rates and increases in survival rates were recognized.
