HCC Epidemiology HCC and The Globe • HCC is the most common primary liver cancer • The incidence is increasing worldwide • Among men, HCC is the 5th most common cancer • It is the 3rd lethal cancer worldwide • 711,000 Cases of HCC in 2007 • Every year, 694,000 deaths from liver cancer

Definitions HCC Surveillance Definitions • Screening • Screening is a public health service in which members of a defined population are offered a test to identify those individuals who are more likely to be helped than harmed by further tests or treatment to reduce the risk of a disease or its complications. • Surveillance • The continuous monitoring of disease occurrence (using the screening test) within an at-risk population to achieve the same goals as screening • For HCC, surveillance is recommended Meissner Hi, et al,Cancer 2004 Sherman M, et al, Hepatology 1998
Patients for Whom HCC Surveillance Is Recommended HCC Surveillance Asian males HBV carriers older than 40 yrs of age Asian female HBV carriers older than 50 yrs of age HBV carrier with HCC family history African/N American blacks with HBV Cirrhotic HBV carriers Hepatitis C with cirrhosis Stage 4 primary biliary cirrhosis Genetic hemochromatosis and cirrhosis Alpha-1 antitrypsin deficiency and cirrhosis Other cirrhosis 80% of patients with HCC have underlying cirrhosis Bruix J, et al.

Screening for HCC: AASLD Recommendations HCC Surveillance Screening for HCC:AASLD Recommendations • Population in which screening should be done • Cirrhosis (any etiology) • HBV: older, family history, cirrhosis • Surveillance for HCC should be performed with ultrasonography • AFP alone should not be used for surveillance unless ultrasonography is not available • Screening should occur every 6 months

HCC Surveillance Effect of Surveillance on Outcomes • Retrospective analysis of patients with cirrhosis and HCC (N = 269) • Standard-of-care surveillance (n = 172) • Ultrasound or other abdominal imaging ≥1 time/year • Substandard surveillance (n = 48) • Lack of abdominal imaging within 1 year of cancer diagnosis • Absence of surveillance (n = 59)
HCC Surveillance Surveillance Recommendations Surveillance Recommendations • The target population for surveillance are those with liver cirrhosis (and HBV-infected patients) • AFP and US are the recommended screening tests for HCC in patients at the highest risk • Based on tumor doubling time and studies, the recommended interval for surveillance is every 6 months in patients with cirrhosis • Screening increases likelihood of HCC diagnosis • Small and potentially treatable • May reduce mortality
HCC Surveillance • Review records of patients > 65 YO diagnosed with HCC between 1994-2002 • Number of cirrhotic patients with HCC was 1,873 • Only 17% received regular surveillance
HCC Surveillance Those seen by Gastroentrologist/Hepatologist or by a Doctor with an academic affiliation were more likely to have regular surveillance by 4.5 fold and 2.8 fold respectively than those seen by PCPs only Getting ”Better”: Regular surveillance increased from 9% in 1994-1996 to 21% in 2000-2002
HCC Diagnosis Dual Blood Supply of Liver • The vascular supply of HCC arises from the hepatic artery through neovascularization. • 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

Multidisciplinary HCC Management HCC Treatment • HCC is the intersection of 2 diseases • Liver disease and cancer • Skilled Radiologists “pathologists” needed for diagnosis • Specialists required to deliver treatment options • Surgeons for resection or transplantation • Radiologists for ablation and chemoembolization • Hepatologists and oncologists follow treatment strategy and labs
