Biliary Tract Tumor, Cholangiocarcinoma
Conditions
Brief summary
A prospective, observational study to explore multidimensional biomarkers for predicting the efficacy of immunotherapy In biliary tract tumors
Detailed description
Patient with unresectable advanced or metastatic biliary tract tumors will be enrolled and plan to receive PD-1/PD-L1 inhibitors combined with chemotherapy as first-line treatment. To explore the biomarkers, tumor tissues, acquired from puncture biopsies at baseline, will be collected and investigated by genomic panel sequencing , transcriptome sequencing, and mIHC. Meanwhile, baseline peripheral blood and feces were also collected for detection of plasma proteins, genomes, and metagenomes. Finally, the investigators will analysis and explore predictive biomarkers of immunotherapy in biliary tract tumors.
