Treatment outcomes associated with surgery for gallbladder cancer: a 20-year experience

The aim of this study was to evaluate contemporary outcomes associated with the management of gallbladder cancer. The medical records of 48 consecutive patients with gallbladder cancer treated at our institution from January 1981 through November 2001 were reviewed. Survival was analyzed using the Kaplan-Meier method (mean follow-up period 24 months) and the log-rank test. Prognostic factors were analyzed using Cox regression. Mean patient age was 68 years. Sixty percent of patients were female. Thirty-nine patients (81%) underwent laparotomy or laparoscopy. Eighteen patients (38%) underwent complete resection (10 simple cholecystectomies and 8 radical cholecystectomies). There were no procedure-related deaths. The overall 5-year survival rate was 13%. Patients who underwent complete resection had a higher 5-year survival rate (31%) than patients who underwent palliative surgery or no surgery (0%; P<0.05). For patients who underwent radical cholecystectomy, the 5-year survival rate was 60%. For the 18 patients who underwent curative resection, positive lymph node metastasis and patient age over 65 were factors predictive of significantly worse survival. Overall survival rates for patients with gallbladder cancer remain poor. Although radical surgery can be performed safely, it is associated with long-term survival only in a highly select subset of patients with gallbladder cancer.
