Chemoembolization for Hepatocellular Carcinoma: Multivariate Analysis of Predicting Factors for Tumor Response and Survival in a 362-Patient Cohort

Tumor size, tumor vascularity, tumor number, and portal vein invasion are significant independent predictors of tumor response after chemoembolization in patients with unresectable HCC. Child-Pugh class B or C, large tumor size (≥ 4 cm), multiple tumors (five or more), portal vein invasion, and a high AFP value (> 83 ng/mL) indicated poor prognosis for overall patient survival after chemoembolization.
