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

Not Applicable

Recruiting

• Conditions: Cholangiocarcinoma; Ampullary Cancer; Hepatobiliary Cancer; Pancreatic Cancer; Hepatocellular Carcinoma; Pancreatic Carcinoma
• Interventions: Diagnostic Test: ctDNA Blood Collection

• Registration Number: NCT05497531
• Lead Sponsor: University of California, Irvine

Brief Summary

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).

Arm && Interventions

Group	Intervention	Description
ctDNA collection from draining and peripheral veins	ctDNA Blood Collection	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.

Primary Outcome Measures

Name	Time	Method
Comparison of the amount of ctDNA in draining vein plasma sample to peripheral vein sample through ratio of mean allele frequency	Up to 1 year	Ratio of mean allele frequency (MAF)% of hepatic or portal draining vein, and MAF% of peripheral blood will be utilized to compare the samples

Secondary Outcome Measures

Name	Time	Method
Number of unique alterations found in ctDNA compared to number of alterations derived next generation sequencing (NGS)	Up to 1 year	ctDNA results will be compared with percutaneous biopsy (standard of care)
Number of unique alterations found in hepatic or portal vein plasma compared to number of alterations found in peripheral vein plasma	Up to 1 year	ctDNA results will be compared with percutaneous biopsy (standard of care)
