tace combined with "target immune" therapy for first-line treatment in the treatment of intrahepatic cholangiocarcinoma

Conditions: Intrahepatic Cholangiocarcinoma

Summary: this study is a prospective, multicenter, open, real-world clinical study. all eligible patients were assigned to experimental group (tace combined with multi-target drugs and pd-1 inhibitors), and control group (conventional intravenous chemotherapy), to explore the efficacy and safety of tace combined with multi-target drugs and pd-1 inhibitors as first-line treatment compared with traditional systemic intravenous chemotherapy in the treatment of unresectable intrahepatic cholangiocarcinoma (icc).

this study is a prospective, multi-center, open, and double-arm clinical study in the real world, which belongs to a practical clinical trial. the type of comparison is the non-inferiority test. this study enrolls 98 patients with unresectable intrahepatic cholangiocarcinoma at multiple centers across the country. in the experimental group, 49 patients will receive tace combined with immune checkpoint inhibitors and multi-target drugs; in the control group, 49 patients will receive traditional systemic intravenous chemotherapy with gemox regimen.
