Current Situation of Postoperative Adjuvant Chemoradiotherapy for Extrahepatic Cholangiocarcinoma

Abstract

In recent years, the incidence of extrahepatic cholangiocarcinoma (ECC) has been increasing annually. As a result of frequently invading adjacent structures, such as hepatic artery, hepatic vein, and portal vein, and low radical resection rate, the prognosis is poor. Even if radical resection is completed early, the 5-year survival rate is still less than 30%. At present, whether postoperative adjuvant therapy can improve the prognosis of ECC remains a research hotspot and a controversial point. This article will combine the latest research results to discuss the plan and status of postoperative adjuvant therapy after ECC, as well as analyze the effect of postoperative adjuvant therapy on ECC.
