Clinical Trial Summary

1. Establish a predictive model for the efficacy of immune checkpoint inhibitors (ICI) in Chinese patients with biliary tract cancers. By analyzing the dynamic changes of circulating tumor DNA (ctDNA) and other clinical and pathological features before and after ICI treatment in a cohort of patients with biliary tract tumors, a predictive model can be established to evaluate the efficacy of ICI treatment in the early stages or even before treatment, serving as a reliable tool for selecting patients who are likely to benefit from ICI treatment.

2. Investigate the clinical features of populations that benefit from different immune combination therapies. By comparing the differences and enrichment of mutations between patients receiving different treatment regimens, and if patients have sufficient pre-treatment tissue, further comparisons of differentially expressed genes and pathways may be made.

• According to RECIST V1.1, the patient had at least one measurable lesion.

• The patient is suitable for treatment with immune checkpoint inhibitors (PD-1/PD-L1 inhibitor).

Exclusion Criteria:

• Suffering from other malignant tumors.

• Previous systemic treatment received.

• Previously received any cell or organ transplant treatment.

• Allergy to the therapeutic drugs of this study or CT or MRI-enhanced contrast agents.

• Received local hepatobiliary treatment (including various types of ablations, percutaneous ethanol or acetic acid injection, high-intensity focused ultrasound, transarterial embolization, chemotherapy, or chemoembolization) within 14 days before the start of the study treatment.

• The physician determines that there are any contraindications to ICI treatment.

• During the second blood monitoring, the disease changes could not be judged (such as unexplained ascites, worsening symptoms); Or non-disease progression, but the next immunotherapy is not planned.
