Brief summary: The aim of this study is to the efficacy, prognosis, adverse effects, and factors for predicting therapeutic effects and clinical prognosis of combined therapy of Drug-eluting Beads-transarterial chemoembolization (DEB-TACE), lenvatinib, and anti-PD-1/ PD-L1 antibody for patients with advanced intrahepatic cholangiocarcinoma who were initially unsuitable for the radical therapy, including resection, transplantation, or ablation.

Detailed description: The multicenter, non-random, open and prospective real-world cohort study is conducted at 4 research centers, including 3 centers (Hankou, Sino-French New District, and Optical Valley) of Tongji hospital (Wuhan, China) and one in the second affiliated hospital of Fujian Medical University (Quanzhou, China). It is estimated that 100 patients with advanced intrahepatic cholangiocarcinoma will be enrolled in these 4 research centers. And it is planned to complete the enrollment within 2 year and it is expected that all enrolled subjects will reach the observation end point in 3 years. Radiological assessments are performed every two cycles over the course of treatment, then every 3 months within the first two years following the completion of treatment and every 6 months thereafter, until PD were recorded. All subjects are followed until death or lost to follow up.
