abstract = {Background: The 2018 guidelines for treatment of cancer by site recommended by the National Comprehensive Cancer Network (NCCN) does not include a specific treatment recommendation for rectal cancer patients who did not receive preoperative chemoradiotherapy. The study objective was to evaluate whether postoperative radiotherapy was effective for such patients.
Methods: Survival was evaluated in 9,585 patients who underwent surgical resection for stage II or III rectal cancer and were registered in the Surveillance, Epidemiology, and End Results-Medicare database between 1992 and 2009. Overall survival (OS) benefit in propensity score (PS)-matched patient cohorts were estimated by Cox proportional hazards models.
Results: After stratification by chemotherapy regimen, the difference in OS of stage III patients between the no-treatment and radiotherapy groups was significant (P},
