Radical surgery for de novo gallbladder carcinoma-Single-center analysis of prognostic factors and survival outcomes from an endemic region

Background and Objective Gallbladder cancer (GBC) is an aggressive malignancy where curative resection is possible in few and survival is poor. There are limited data on outcomes in patients with de novo GBC from endemic regions undergoing surgery for curative intent. We report survival outcomes in this group of patients from a region with high incidence of disease. Methods We reviewed the records of all GBC patients (2014-2018) and included those who underwent radical cholecystectomy (RC) for de novo GBC. Univariable and multivariable analyses were performed to identify factors influencing recurrence and survival. Results A total of 649 patients with GBC were evaluated for surgery and curative intent surgery was attempted in 246 (38%) patients. Of these 246 patients, RC was performed in 115 patients, with histologically confirmed de novo GBC. Locally advanced disease (>= stage IIIB) was present in 52 (45.2%) patients. Median time to recurrence and overall survival (OS) were 31 and 36 months, respectively. Lymph node positivity (p = 0.005) and grade significantly influenced OS on multivariable analysis. Conclusion Satisfactory survival outcomes are possible after RC for de novo GBC. Extended resections performed in high volume centers combined with appropriate adjuvant treatment can offer significant survival benefits, with acceptable morbidity and mortality rates.
