Liquid Biopsy in Biliary Tract Cancer: When Tissue is Not Enough

Lewis Au, Jeanne Tie

Abstract

Circulating tumor DNA (ctDNA) profiling detects actionable genomic alterations in advanced biliary tract cancer faster (8 vs 27 days) and more often (90% vs 50%) than tissue, with high concordance. A recent retrospective study establishes clinical validity and a compelling access case for future prospective ctDNA-directed trials.
