Abstract    Gallbladder carcinoma represents the most common and malignant type among the biliary tract carcinomas associated with poor prognosis. A reasonable staging system is directioe to treatments selection and prognosis evaluation. Multiple staging systems have been described for gallbladder carcinoma, which have their own advantages and disadvantages. Tumor-node-metastasis (TNM) staging system for gallbladder carcinoma, developed by the American Joint Committee on Cancer (AJCC) and the International Union Against Cancer (UICC), is the most widely used and recommended system. The novel seventh edition has been used since 2010 instead of the 6th edition published in 2002. The new version is a guideline for the appropriate therapy of gallbladder carcinoma in future although there are still some flaws. Other stage systems have their advantages besides AJCC.
