Objective:The effectiveness of adjuvant treatments for resected gallbladder carcinoma(GBC)has remained unclear due to lack of randomized controlled trials;thus,the aim of present study was to evaluate the role of adjuvant treatments,including chemoradiotherapy(CRT)and/or chemotherapy(CTx),in patients with resected GBC.Methods:A total of 733 GBC patients who received curative-intent surgical resection were identified in a multi-institutional database.Of 733 patients,372(50.8%)did not receive adjuvant treatment,whereas 215(29.3%)and 146(19.9%)received adjuvant CTx and CRT,respectively.The locoregional recurrence-free survival(LRFS),recurrence-free survival(RFS),and overall survival(OS)of the adjuvant treatment groups were compared according to tumor stage(stage II vs.stage III–IV).Results:In stage II disease(n=381),the 5-year LRFS,RFS,and OS were not significantly different among the no-adjuvant therapy,CTx,and CRT groups,and positive resection margin,presence of perineural invasion,and Nx classification were consistently associated with worse LRFS,RFS,and OS in the multivariate analysis(P<0.05).For stage III–IV(n=352),the CRT group had significantly higher 5-year LRFS,RFS,and OS than the no-adjuvant therapy and CTx groups(67.8%,45.2%,and 56.9%;37.9%,28.8%,and 35.4%;and 45.0%,30.0%,and 45.7%,respectively)(P<0.05).Conclusions:CRT has value as adjuvant treatment for resected GBC with stage III–IV disease.Further study is needed for stage II disease with high-risk features. 展开更多
