Risk of new primary nonbreast cancers after breast cancer treatment: A dutch population-based study

Purpose: To assess the risk of secondary nonbreast cancers (SNBCs) in a recently treated population-based cohort of breast cancer patients focused on the association with treatment and prognostic implications. Patients and Methods: In 58,068 Dutch patients diagnosed with invasive breast cancer between 1989 and 2003, SNBC risk was quantified using standardized incidence ratios (SIRs), cumulative incidence, and Cox regression analysis, adjusted for competing risks.
