Breast and colorectal cancer recurrence and progression captured by five US population-based registries: Findings from National Program of Cancer Registries patient-centered outcome research

摘要

Objectives: Cancer recurrence is a meaningful patient outcome that is not captured in population-based cancer surveillance. This project supported National Program of Cancer Registries central cancer registries in five U.S. states to determine the disease course of all breast and colorectal cancer cases. The aims were to assess the feasibility of capturing disease-free (DF) status and subsequent cancer outcomes and to explore analytic approaches for future studies.
