The chemotherapeutic efficacy is heterogeneous among cholangiocarcinoma patients after radical resection, and an accurate and relatively convenient model evaluating the chemotherapeutic efficacy is still lacking. This study aims to prospectively evaluate the consistency of drug sensitivity between patient-derived organoid model and the actual clinical chemotherapeutic efficacy in cholangiocarcinoma patients, assisting in guiding precision medicine and making therapeutic decisions.~Drug sensitivity tests include single drug and drug combination. The organoids that are successfully cultured will be kept in liquid nitrogen for a specific time.
This is a single-center, prospective, observational and exploratory clinical study. The object of this study is to evaluate the consistency and accuracy of patient-derived organoid model of cholangiocarcinoma to predict the clinical chemotherapeutic efficacy, as well as the possibility of guiding the adjuvant chemotherapy.
