Disparities in overall survival of gastric cancer patients after radical gastrectomy: an age and rural-urban residence-based cohort study with propensity score matching analysis.

ABSTRACT: This study estimated overall survival (OS) among gastric cancer patients stratified by age and rural-urban residence after radical gastrectomy. Patients (n = 286) undergoing curative gastrectomy were categorized into four groups based on age (older ≥ 60 years or younger < 60 years) and residence (rural or urban), including rural older (G1), urban older (G2), rural younger (G3) and urban younger (G4) groups. G1 presented with significantly more males, upper stomach cancers and total gastrectomies, while less patients receiving ≥ 4 cycles of adjuvant chemotherapy. The 5-year OS rates were 39.9% for G1, 61.1% for G2, 73.1% for G3, and 71.2% for G4, with a median OS of 47 months in G1 and not reached for other groups. OS was significantly worse in G1 than other groups (P < 0.05). Multivariate
