Whole exome sequencing of multi-regions reveals tumor heterogeneity in Opisthorchis viverrini-associated cholangiocarcinoma
29 Mar 2025
Abstract excerpt
The study examines Opisthorchis viverrini (OV)-related cholangiocarcinoma (CCA), a serious malignancy common in Southeast Asia. Through multi-regional whole-exome sequencing of 52 tumor samples and 13 adjacent tissues from 13 patients, significant intratumoral heterogeneity (ITH) and inter-patient heterogeneity are shown. Chronic liver fluke infection induces a distinct mutational landscape, with 48-90% of...
