BACKGROUND/AIMS: Few studies, with small samples and diverging results, have been performed to evaluate the p53 protein expression in gallbladder carcinoma and its relationship to different clinicopathological parameters. Based on these facts, we performed a study for the purpose of assessing p53 expression in this disease and its association to prognostic factors. MATERIAL AND METHOD: Samples of 60 consecutive cases of gallbladder carcinoma were assessed to evaluate the p53 protein expression using the immunohistochemical technique (streptoavidin-biotin-peroxidase) and their relationship with survival and prognosis factors was studied. The prognosis of this neoplasm was performed using the Nevin classification and TNM staging system. RESULTS: p53 expression was positive in 58.3% of carcinomas of the gallbladder. No association was found between p53 protein expression and prognostic factors, histological type or grade, presence of gallstones and survival. CONCLUSION: The mutation of gene p53 is probably involved in the pathogenesis of the gallbladder carcinoma. Our data does not show an association between p53 protein expression and survival or prognostic factors.
