简要总结
This study is a prospective, observational study designed to analyze the safety, tolerability, and efficacy of first-line treatment using the combination of gemcitabine and cisplatin plus anti-PD-1/PD-L1 antibodies for patients with advanced cholangiocarcinoma.
详细描述
This is a prospective cohort study of combination anti-PD-1/PD-L1 antibodies plus Gemcitabine and Cisplatin chemotherapy for adult patients (≥18) with advanced cholangiocarcinoma
Gemcitabine and Cisplatin (GC): This chemotherapy doublet has been the historical standard of care for advanced cholangiocarcinoma. It works by interfering with DNA synthesis and causing DNA cross-linking, leading to tumor cell apoptosis.
Anti-PD-1/PD-L1 antibodies: Immunotherapy (including pembrolizumab, durvalumab, envafolimab, tislelizumab, etc.) is designed to block the PD-1/PD-L1 immune checkpoint pathway, thereby reinvigorating T-cells to recognize and attack tumor cells. Recent pivotal trials (e.g., TOPAZ-1, KEYNOTE-966) have demonstrated that adding immunotherapy to GC chemotherapy significantly improves overall survival compared to chemotherapy alone.
This study aims to evaluate the real-world safety, tolerability, and clinical efficacy of this combination regimen in specific clinical practice settings for unresectable late-stage cholangiocarcinoma patients.
