Radiotherapy, Alkylating Agents, and Risk of Bone Cancer After Childhood Cancer

Abstract

This population-based study provides grounds for reassurance of the majority of survivors in that their risk of developing bone cancer within 20 years of 3-year survival did not exceed 0.9%. The higher risks found for bone cancer following the other specific rare types of childhood cancer provide a rational basis for surveillance. The RRs reported for bone cancer after specified levels of exposure to radiation should help in making decisions concerning future treatment protocols.
