Value of clinical staging and typing of hilar cholangiocarcinoma in evaluating radical resection and prognosis / 临床肝胆病杂志

ABSTRACT

Hilar cholangiocarcinoma (HCCA) is a malignant tumor arising from the epithelium of the bile duct, which involves the common hepatic duct, the left and right hepatic ducts, and the confluence areas of these bile ducts. HCCA has an insidious onset and most patients are in the advanced stage when jaundice is observed, and therefore it is considered a difficult issue in the field of surgery. Radical resection is the optimal method for the treatment of HCCA and has great influence on recurrence rate of tumor and patients’ survival time. Therefore, preoperative evaluation of tumor resectability is an important step of HCCA treatment. At present, there are eight main methods for HCCA staging and typing, i.e., Bismuth-Corlette classification system, modified T staging system, TNM staging system, JSBS staging system, Gazzaniga staging system, International Cholangiocarcinoma Group staging system, Mayo staging system, and Blechacz staging system. Each staging and typing system has its own advantages and disadvantages in clinical practice. This article reviews the staging and typing methods for HCCA, with a focus on the clinical value of each staging and typing system in preoperative evaluation of radical resection and prognosis.
