This is a prospective pilot protocol investigating whether ctDNA detection be improved by sampling the cancer draining vein versus the standard practice of sampling from a peripheral vein in patients who are undergoing biopsies for hepatobiliary and pancreatic cancers.

Official Title

Pilot Trial Comparing Circulating Tumor DNA (ctDNA) From Immediate Draining Vein vs. Standard Peripheral Vein Sample in Patients Undergoing Biopsies for Hepatobiliary and Pancreatic Cancers


This is a, prospective single center pilot study to investigate whether ctDNA detection can be improved by sampling the cancer draining vein vs. a peripheral vein (current practice). As a secondary endpoint, both ctDNA results will be compared with percutaneous biopsy (standard of care).
