Abstract
Perihilar cholangiocarcinoma (PCC) is a malignant mass originating from the bile ducts. There is currently no unified treatment plan, and there are various treatment methods applied in clinical practice, as well as several different staging and typing systems to guide resectability, prognosis and survival prediction. The choice of treatment for PCC is closely related to the stage of the tumor. Accurate preoperative staging is necessary for correct resectability assessment and the selection of a reasonable treatment plan and surgical method; similarly, accurate postoperative pathological staging is necessary to guide further treatment and judgment of the patient's prognosis. A universally accepted staging system facilitates the comparison of cases between different centers, but there is much debate about the classification and staging of PCC. At present, the existing staging systems include the Bismuth-Corlette classification, AJCC/UICC TNM staging, modified T staging, Gazzaniga staging, JSBS staging, and Mayo staging. Each system has advantages, but there is no comprehensive guide for tumor resectability, prognosis, and survival. In this paper, the pros and cons of the different systems for staging PCC in terms of resectability, prognosis and survival prediction are discussed.
