Diffuse Infiltrative Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis Completely Cured by Transcatheter Arterial Chemoembolization: Case Report with 8-Year Follow-Up

Hepatocellular carcinoma (HCC) is the most common type of liver cancer and its treatment options are determined by shape, liver function, loci, and stages of cancer.
