Purpose:
Incidental gallbladder cancer (IGBC) is defined as gallbladder cancer (GBC) that is accidentally discovered during cholecystectomy to treat benign lesions. We aimed to compare the prognosis of IGBC patients who underwent simultaneous radical resection (SIR) vs salvage radical resection (SAR).
Patients And Methods:
We retrospectively reviewed data for IGBC patients admitted to Sir Run Run Shaw Hospital from January 2000 to May 2016. Survival analysis was performed using Kaplan-Meier (univariate) and COX regression (multivariate) analyses.
Results:
Eighty-four patients with IGBC underwent radical resection; 43/84 underwent SIR, and 41/84 underwent SAR. Compared with SIR, the SAR group was more likely to receive comprehensive preoperative radiographic evaluation, port-site excision, and have more lymph nodes excised (all P < 0.05). Kaplan-Meier analysis indicated that the prognosis in the SAR group was better than that in SIR (overall survival: P = 0.050, recurrence-free survival: P = 0.028). Regression analysis indicated that the type of radical resection (SIR/SAR) was not an independent prognostic factor (overall survival: P = 0.737, recurrence-free survival: P = 0.957).
Conclusion:
Patients undergoing SAR had non-inferior survival compared with SIR. It is possible that patients in SAR underwent preoperative radiographical evaluations more comprehensively and the surgical operations were more well performed.
