Abstract: Objective: To explore the relationship between iodinate oil filling shape and the clinical effect after chemoembolization for liver cancer.Methods: Sixty cases of primary hepatocellular carcinoma underwent radiography and transcatheter iodinate oil chemoembolization(TOCE) via proper hepatic artery.CT scan was performed four to six weeks after TOCE.The shape of iodinate oil concentration and its relationship with the survival rate were analyzed.Results: The iodinate oil filling shape after chemoembolization for liver cancer after TOCE could be classified into four types according to the distributive limits and deposition extent of iodized oil:complete type,defective type,aggregated type and sporadic type,the 2-year survival rates of these four types were 69.2%,57.9%,(20.0%) and 0/8,respectively.Conclusions: Clinical therapeutic effect is closely related to the iodinate oil morphology.The more iodinate oil is filled,the higher the survival rate will be.
