To examine the histopathological link between intrahepatic bile duct hyperplasia and the development of cholangiocellular carcinoma.
Histologically examined liver tissue specimens from 27 patients with cholangiocellular carcinoma (including biliary cystadenocarcinoma) and 303 non-cancer controls.
Assessed the presence, anatomical location, and histological transitions among bile duct hyperplasia, atypical hyperplasia, and carcinoma in situ across intrahepatic bile duct sizes.
Carcinoma specimens demonstrated high rates of concurrent hyperplasia (100%), atypical hyperplasia (77.8%), and carcinoma in situ (51.9%), with direct transitions between these stages frequently observed.
Large intrahepatic bile ducts showed the highest frequency of pre-invasive and hyperplastic changes, with all 27 cancer cases originating in or near the hepatic hilus.
Bile duct hyperplasia was commonly observed in controls older than 30 years of age, whereas cholangiocellular carcinoma primarily occurred in individuals between 50 and 80 years of age.
