肝内胆管癌是一种原发性肝癌。近年来,该病发病率在国内外呈明显上升趋势。因发病隐匿,侵袭性强,且缺乏有效治疗方法,肝内胆管癌预后极差。国家科技部传染病防治重大专项课题专家组基于国内外本领域研究获得的循证医学证据,并结合符合我国国情的临床实践,特制订《肝内胆管癌外科治疗中国专家共识(2020版)》。该共识针对肝内胆管癌的危险因素、发病机制、病理特征、临床表现、诊断方法、疾病分期、外科治疗、辅助治疗,以及其他局部、区域性和系统性治疗进行系统阐述,旨在规范、普及和提高对肝内胆管癌的诊断和多学科治疗水平,改善该病总体预后。“,”Intrahepatic cholangiocarcinoma (ICC) is one of the primary liver cancer. The incidence of ICC has been increasing over the past decades globally. The prognosis of ICC is extremely poor due to its difficult early diagnosis, high aggressiveness, and lack of effective treatments. Based on the evidence-based medical evidence obtained from the international studies on ICC in recent years, as well as the clinical practice in our country, the expert group of the Major Special Project of Infectious Disease Prevention and Control of the Ministry of Science and Technology of the People's Republic of China formulate the 'Chinese expert consensus on the surgical manage-ment of intrahepatic cholangiocarcinoma (2020 edition)', which has systematically addressed the risk factors, pathogenesis, histopathological features, clinical manifes-tations, diagnostic methods, staging, surgical and adjuvant treatment, and other local, regional and systemic treat-ments of ICC. This consensus is designed to standardize and popularize the diagnosis and multidisciplinary treat-ment of ICC to improve overall prognoses of the disease.
