    Abstract:
    CONTEXT: Survivors of childhood cancer are at increased risk of premature mortality compared with the general population, but little is known about the long-term risks of specific causes of death, particularly beyond 25 years from diagnosis at ages when background mortality in the general population starts to increase substantially. OBJECTIVE: To investigate long-term cause-specific mortality among 5-year survivors of childhood cancer in a large-scale population-based cohort. DESIGN, SETTING, AND PATIENTS: British Childhood Cancer Survivor Study, a population-based cohort of 17,981 5-year survivors of childhood cancer diagnosed with cancer before age 15 years between 1940 and 1991 in Britain and followed up until the end of 2006. MAIN OUTCOME MEASURES: Cause-specific standardized mortality ratios (SMRs) and absolute excess risks (AERs). RESULTS: Overall, 3049 deaths were observed, which was 11 times the number expected (SMR, 10.7; 95% confidence interval [CI], 10.3-11.1). The SMR declined with follow-up but was still 3-fold higher than expected (95% CI, 2.5-3.9) 45 years from diagnosis. The AER for deaths from recurrence declined from 97 extra deaths (95% CI, 92-101) per 10,000 person-years at 5 to 14 years from diagnosis, to 8 extra deaths (95% CI, 3-22) beyond 45 years from diagnosis. In contrast, during the same periods of follow-up, the AER for deaths from second primary cancers and circulatory causes increased from 8 extra deaths (95% CI, 7-10) and 2 extra deaths (95% CI, 2-3) to 58 extra deaths (95% CI, 38-90) and 29 extra deaths (95% CI, 16-56), respectively. Beyond 45 years from diagnosis, recurrence accounted for 7% of the excess number of deaths observed while second primary cancers and circulatory deaths together accounted for 77%. CONCLUSION: Among a cohort of British survivors of childhood cancer, excess mortality from second primary cancers and circulatory diseases continued to occur beyond 25 years from diagnosis.
