HCC: Common and Increasing

694,000 deaths from liver cancer yearly worldwide[1]

Age-adjusted US incidence has increased 2-fold from 1985-1998[2] Expected to continue to increase until 2015-2020[3]

American Cancer Society statistics for liver cancer in 2010[4] Estimated new cases: 24,120 Estimated deaths: 18,910 5th leading cause of cancer deaths in males

Comparison of HCC Staging Systems

BCLC system uses key independent predictors of survival: Performance score, portal vein thrombosis, tumor

diameterCompared with other staging systems in cohort

study BCLC had best stratification of survival across all stages BCLC was only system to have independent predictive

value on survivalBCLC is the only staging system that stratifies

patients into treatment groupsMarrero JA, et al. Hepatology. 2005;41:707-716.

Treatment of HCC: Chemoembolization

Normal liver gets 75% of blood supply from portal vein and 25% of blood supply from hepatic artery

Tumor receives most of its blood supply from the hepatic artery

Injection into the hepatic artery spares most of the normal liver

Embolization of the hepatic artery induces ischemic necrosis of tumor

characteristics and tumor characteristics BCLC staging system recommended by US and

European guidelines BCLC system provides framework for selection

of treatment Many studies ongoing for treatment of HCC
