Histopathological study of hepatocellular carcinoma after transcatheter hepatic arterial embolization

摘要

AIMS To study the histopathological changes in hepatocellular carcinoma (HCC) after transcatheter arterial embolization (TAE). METHODS Histopathological analysis was made in 39 cases of liver neoplasms after TAE and 11 cases of liver neoplasms after digital selective angiography (DSA), including pathological type, histological grade, necrotic degree, capsule, times of treatment, injured Vessel and lymphocyte infiltration. RESULTS Six cases with 100% necrosis, 14 cases with 30%-95% necrosis, 19 cases with 0%-5% necrosis after TAE and 11 cases without necrosis after DSA were found histologically. The necrosis was related to the pathological type, capsule, injured vessels, but not to the histological grade, time of treatment and lymphocyte infiltration of the liver neoplasms. CONCLUSIONS TAE is an effective therapy for the late-stage HCC. The encapsulated HCC is a preferable indicator for TAE.
