Progress of immunotherapy of cholangiocarcinoma / 中华肝胆外科杂志

ABSTRACT

Cholangiocarcinoma (CCA) is a group of solid tumors with high malignant degree and poor prognosis. Surgical resection has still been the main therapy options. Targeting therapy and immunotherapy are the main anti-tumor methods that have been paid more and more attention in recent years, especially immunotherapy. The tumor microenvironment of CCA is complex, which encompasses not only interstitial and endothelial cells, but also a large number of immune cells. In addition, the innate and adaptive immune systems also play a role. This article summarizes the immune-related studies of cholangiocarcinoma and the latest clinical trials of immunotherapy.
