Muddy Water? Variation in reporting receipt of breast cancer radiation therapy by population-based tumor registries

摘要

PurposeReceipt of radiation therapy (RT) is a key quality indicator in breast cancer treatment. Prior analyses using population-based tumor registry data have demonstrated substantial underuse of RT for breast cancer, but the validity of such findings remains debated. To address this controversy, we evaluated accuracy of registry RT coding compared to the gold standard of Medicare claims.
