Abstract

Background Many studies have demonstrated the advantage of postoperative concurrent chemoradiotherapy (CRT) over radiotherapy (RT) alone in locoregional control, but few have examined overall survival with respect to national databases. Methods The literature was searched for eligible randomized controlled trials. The Surveillance, Epidemiology, and End Results (SEER) Database and National Cancer Data Base (NCDB) were searched for 5-year overall survival data. Results Twenty-eight studies were examined and demonstrated 44% greater locoregional control (relative risk [RR] = 0.56; 95% confidence interval [CI] = 0.46-0.68) and 12% overall survival benefit (RR = 0.88; 95% CI = 0.81-0.98) with postoperative adjuvant CRT compared to adjuvant RT. Overall SEER survival was 45.0% in 1973, rising to 53.2% in 2005. The NCDB documents a similar increase in overall survival from 45.5% in 1994 to 53.4% in 2005. Conclusion The literature shows mortality benefit of adjuvant CRT in patients with advanced head and neck cancer, reflected in SEER and NCDB.
