About

This study intends to use Onconscreen plus 520 Panel (Burning Rock, China) to conduct NGS testing in matched tissue, blood , and bile samples of patients with Resectable Biliary Tract Carcinomas(BTC). In order to explore thefeasibility in bile cfDNA of BTC,we will collect relevant clinical information and follow-up treatment information. This study aims to reveal the effectiveness, accuracy, and feasibility in bile, as compared to tissues and blood samples.

Full description

In this study, we will investigate the potential of bile for genomic alterations using matched tissue, plasma and bile from 20 Resectable BTC Patients。The patient samples will be submitted for next-generation sequencing (NGS),The results will include but will not be limited to genomic profling, tumor mutation burden (TMB), microsatellite instability (MSI) status, homologous recombination repair deficiency (HRD)。Patients will be followed-up for treatment responses until radiological confirmation of disease recurrence ,The molecular assay results will then be analyzed with clinical data including objective responses disease-free survival outcomes, among others, to reveal the effectiveness, accuracy, and feasibility in bile, as compared to tissues and blood samples.

Baseline tissues, plasma and sputum samples from 20 Resectable BTC Patients with 520 Panel sequencing (tissue 1000X, ,plasma cfDNA 10000X,bile 10000X), in different methods will be compared.
