and cholangiocarcinoma: molecular mechanisms and biomarker advances

Le résumé fourni par la source

Clonorchis sinensis, a common food-borne liver fluke in East Asia, is a Group 1 carcinogen strongly linked to cholangiocarcinoma. In recent years, molecular biology and multi-omics studies have revealed that this parasite drives chronic inflammation of the bile duct epithelium, epigenetic abnormalities, and the formation of precancerous lesions. Concurrently, circulating miRNAs, DNA methylation patterns, differential protein expression, metabolite profiles, and parasite-specific antigens have been proposed as potential early molecular biomarkers, which offers new avenues for the non-invasive detection of precancerous conditions. However, current research mainly remains at the laboratory stage and studies have small-scale cohorts, lacking multi-center, large-sample prospective validation and standardized detection protocols, which limits their clinical applicability. Furthermore, traditional imaging and histological methods exhibit limited sensitivity for early identification. This review aims to systematically summarize the molecular carcinogenic mechanisms associated with C. sinensis infection, recent advances in molecular biomarker research, and strategies for identifying precancerous lesions. It will particularly focus on discussing the major obstacles in clinical translation and future directions, with the goal of providing insights for early screening and prevention strategies.
