(OA07) Outcomes of Patients in the National Cancer Database Treated Non-Surgically For Localized Rectal Cancer

Some patients undergo a non-operative approach to localized rectal adenocarcinoma due to medical comorbidities that render them poor surgical candidates, and some patients decline surgical intervention. Published studies reporting excellent outcomes (5-year overall survival (OS) of 70-100%) with a "wait-and-see" approach have largely been small, single-institutional, and/or highly selected. In this study, we aimed to analyze the survival outcomes and prognostic factors for patients with localized rectal adenocarcinoma in the National Cancer Database (NCDB) undergoing chemoradiation without surgical intervention.
