Abstract
Background: Gallbladder cancer (GBC) represents the most common and aggressive biliary tract cancer with overall 5-year survival being only 5%–10%. Survival following resection, especially in early stages, has shown some improvement due to advances in surgical treatment. Advanced stages, however, continue to have dismal outcome. Complete surgical resection offers the only chance for cure, which extended from simple cholecystectomy to major hepatectomy or enbloc resection of adjacent organs. The aim of this study was to examine the predictors of longterm survival in patients with gall bladder cancer. Methods: We retrospectively evaluated 38 patients who underwent curative (R0) resection for GBC between January 2001 and December 2010 in Surgical Oncology Department, South Egypt Cancer Institute, Assiut University, Egypt. Surgical procedures included simple cholecystectomy (10.5%), radical cholecystectomy (75.4%), bile duct resection (33.8), and right hepatectomy (7.8%). Adjacent organ resection was performed in (23.4%), duodenal sleeve resection (10.4%), segmental colectomy (5.2%), segmental gastrectomy (2.6%), Hepatopancreatico-duodenectomy (5.3 %). Adjuvant chemotherapy was given for (68.4%) of patients and adjuvant radiotherapy for (36.8%) of patients. Median follow up period of the patients was 38 months (0.5-69 months). Results: The median disease free survival (DFS) for GBC patients was 38 months. Univariate analysis revealed that patient’s age, comorbidities, weight loss, jaundice, tumor differentiation, organ invasion, lymph node metastasis, perineural invasion, tumor stage and chemotherapy were associated with the patient’s survival. Of these, weight loss, jaundice, lymph node metastasis and tumor stage were found to influence the overall survival on the multivariate Cox Hazard Regression analysis. First year overall survival estimate was 86.84% ±5.5%, 2nd year = 71.05% ± 7.4%, Third year 60.53% ± 7.9% fifth year =15.79% ± 5.9%. Conclusion: Curative surgical resection remains the only effective approach for treatment of GBC. This study confirms that jaundice, weight loss and aggressive tumor (advanced stage and regional lymph nodes metastasis) are predictors of poor prognosis.
