Summary

This is a prospective, multicenter, single-arm study investigating the efficacy and safety of preoperative right hepatic artery embolization (PHAE) followed by surgical resection in patients with locally advanced Bismuth IIIb or IV perihilar cholangiocarcinoma (PHCC) involving the right hepatic artery. The standard treatment for such cases is often considered unresectable due to the high risk of hepatic ischemia after arterial resection without reconstruction. This study proposes a strategy: preoperative embolization of the tumor-involved right hepatic artery to stimulate the development of collateral arterial circulation (e.g., from the right inferior phrenic artery), enabling subsequent radical resection of the right hepatic artery without reconstruction. The primary objective is to evaluate the 1-year overall survival rate. Secondary objectives include surgical conversion rate, R0 resection rate, 1-year/3-year recurrence-free survival, 3-year overall survival rate and safety assessment. A total of 33 participants will be enrolled across multiple centers in China.

Conditions

  • Cholangiocarcinoma Non-resectable

Interventions

PROCEDURE

Preoperative Right Hepatic Artery Embolization

Participants receive preoperative selective embolization of the tumor-involved right hepatic artery, followed 2-4 weeks later by radical left hepatectomy or left trisectionectomy with resection of the involved artery without reconstruction.
