Summary

Extrahepatic cholangiocarcinoma (eCCA) is a rare and aggressive cancer with poor prognosis. ECCA can be further subcategorised in perihilar and distal cholangiocarcinoma (pCCA and dCCA). Surgical resection is the only potential cure, but only one-third of patients are eligible. Even among those deemed resectable, a significant portion (30%) experience disease progression before surgery, while another 30% are found unresectable during exploration. High recurrence rates and postoperative complications further limit survival, with 5-year overall survival ranging from 13% (R1 resection) to 40% (R0 resection). Given the long preoperative work-up period and lack of treatment during this phase, a neoadjuvant approach may improve outcomes by increasing R0 resections, reducing recurrence, and optimizing patient selection.

This multicenter, randomized phase 2B/3 trial aims to assess whether neoadjuvant gemcitabine and cisplatin plus perioperative pembrolizumab improves event-free survival in patients with resectable and borderline resectable pCCA and dCCA.
