[New advances in the diagnosis and treatment of intrahepatic cholangiocarcinoma].

Intrahepatic cholangiocarcinoma (ICC) is a type of primary liver cancer, which has shown an increasing trend in incidence and mortality in recent years, with a poor prognosis. The clinical diagnosis and treatment of ICC currently face the challenges of low detection rate, high mortality rate, poor treatment outcome, and urgently need more in-depth research to promote the improvement of clinical diagnosis and treatment level. In recent years, ICC diagnosis and treatment related research has made new progress in many aspects, and the knowledge about these new clinical diagnosis and treatment advances should be updated in a timely manner. This article reviewed the latest research results in recent years, summarized some new views on ICC typing, prevention and diagnosis staging that have been proposed recently, as well as the new progress made in surgical treatment and systemic treatment, and briefly discussed the potential of ICC individualized precision treatment and the occurrence of rare complications caused by combined treatment.
