Since the INT-0116 trial reported a survival advantage, post-operative chemoradiotherapy (CRT) has been a care standard for US patients diagnosed with gastric adenocarcinoma. We sought to estimate the association between treatment and survival among the older U.S. Medicare population. Retrospective cohort study of Medicare beneficiaries aged 65–79 with stage IB-III gastric adenocarcinoma diagnosed between 2002 and 2009 in a Surveillance, Epidemiology, and End Results region. Patients were categorized based on treatment: 1) gastrectomy only, and 2) gastrectomy plus adjuvant CRT. We examined factors associated with adjuvant CRT receipt, including diagnosis stage, comorbidity, and tumor subtype. Overall survival was measured from 90 days post-gastrectomy until death or the censoring date of December 31, 2010. Of the 1519 patients who underwent gastrectomy, 41.7% received adjuvant CRT. Factors associated with adjuvant CRT included age <75 years of age at cancer diagnosis and stage II or III diagnosis. The median overall survival from time of gastrectomy was 25.1 months (interquartile range (IQR), 43.7 months) for gastrectomy only and 26.9 months (IQR, 40.9 months) for adjuvant CRT. Multivariable and propensity score-stratified models demonstrated a survival benefit associated with adjuvant CRT (HR = 0.58 (95%CI, 0.50–0.67), although the magnitude was greater for stage II (HR = 0.50; 95% CI, 0.39–0.61) and III (HR = 0.58; 95% CI, 0.45–0.73) tumors than stage IB (HR = 1.02; 95%CI, 0.71–1.45). Adjuvant CRT, in conjunction with gastrectomy, was associated with a survival benefit among older patients diagnosed with stage II and III tumors.
