Pilot Comparing ctDNA IDV vs. SPV Sample in Pts Undergoing Biopsies for Hepatobiliary and Pancreatic Cancers

February 23, 2026 updated by: Nadine Abi-Jaoudeh, University of California, Irvine

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 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.

Detailed Description

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).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: ctDNA collection from draining and peripheral veins
Patient with suspected primary hepatobiliary or pancreatic cancer undergoing a diagnostic work-up with a percutaneous or trans-jugular biopsy (standard of care) and will undergo a sampling of the cancer draining vein during their biopsy procedure with a collection of an additional 10mL of blood.
Diagnostic test: ctDNA Blood Collection
Blood collection to be obtained from peripheral vein and cancer draining vein during biopsy

What is the study measuring?
