METHODS Five-year survivors primary cancers diagnosed between 1970-1999 Childhood Cancer Survivor Study with CNS SMN were identified. Cumulative incidence rates and standardized ratios (SIR) compared among 1970-1979 (N = 6223), 1980-1989 9680), 1990–1999 8999). Multivariable...

Abstract While >85% of children with cancer will become five-year survivors, they are at substantially increased risk developing subsequent neoplasms (SNs) in part due to DNA-damaging therapy. However, the effects primary therapy on SN genomic landscape unknown.
