Combined Therapy Using D-TACE, Gemcitabine and Cisplatin Chemotherapy, and PD1 Antibody for Patients With Advanced and Unresectable Intrahepatic Cholangiocarcinoma: a Single-center, Single-arm Trial
The goal of this clinical trial is to learn about the combined therapy using drug-eluting bead-transarterial chemoembolization (D-TACE), gemcitabine (Gem) and cisplatin (Cis) chemotherapy, and PD-1 antibody in patients with advanced and unresectable intrahepatic cholangiocarcinoma (ICC). The main questions it aims to answer are: * Whether combined therapy using D-TACE, Gem/Cis, and PD-1 works well to convert unresectable ICC to resectable. * Whether combined therapy using D-TACE, Gem/Cis, and PD-1 is safe. Participants will receive D-TACE (CalliSpheres with Gem 30 mg), camrelizumab (200 mg) plus gemcitabine (1000 mg/m2) and cisplatin (25 mg/m2), and 24 months follow-up.
