U.S., Sept. 22 -- ClinicalTrials.gov registry received information related to the study (NCT07830628) titled 'Bile ctDNA Genomic Profiling and Concordance With Tumor Tissue in Biliary Tract Cancer' on Sept. 15.
Brief Summary: This study is being done to find out whether bile fluid can be used to detect genetic changes in tumors of patients with advanced biliary tract cancer (BTC), such as cancer of the bile ducts or gallbladder.
Currently, doctors often use a sample of tumor tissue to look for genetic changes that can help guide treatment decisions, including the use of targeted therapies. However, in biliary tract cancer, it can be difficult or risky to collect enough tumor tissue for this kind of testing.
This study will collect a smal...
