HCC Diagnosis Guidelines for Diagnosis of HCC Ultrasound findings Typical features of HCC = vascular nodule on arterial phase with washout in delayed phases Bruix J, et al, Hepatology 2005
HCC Diagnosis Dual Blood Supply of Liver • The vascular supply of HCC arises from the hepatic artery through neovascularization. • Normal hepatocytes receive 80% of blood flow from portal vein • Imaging of the liver has to be performed in a triple phase manner to account for the early arterial phase followed by the portal venous phase and the delayed phases Yu JS, et al, Am J Roentgenol 1999

HCC Treatment Key Concepts in the Management of Hepatocellular Cancer Key Concepts in the Management of Hepatocellular Cancer • Potentially Curative • Liver transplantation (75% 5-year survival) • Surgical resection • Palliative • Radiofrequency ablation (RFA) • Transarterial chemoembolization (TACE) • Percutaneous ethanol or acetic acid ablation • Cryoablation • Systemic Chemotherapy
HCC Treatment Key Concepts in the Management of Hepatocellular Cancer Key Concepts in the Management of Hepatocellular Cancer • Liver transplantation achieves the best outcome in HCC patients with decompensated cirrhosis who meet criteria • Surgical resection is most effective for non-cirrhotic patients or those with cirrhosis and preserved liver function and can be followed by salvage OLT • Patients with small tumors are best stratified for resection or OLT by the presence of clinically-significant portal hypertension and/or increased serum bilirubin • Local ablative methods are an option for small solitary nodules and those who are not surgical candidates • Transarterial chemoembolization improves survival in intermediate-advanced HCC
HCC Treatment Management of Hepatocellular Carcinoma Requires a Multidisciplinary Approach Hepatobiliary Surgery Hepatology Oncology Pathology Radiology Liver Transplant Program
