Overview
HCC: A growing problem…• Incidence: 4.1/100K in US• male to female ratio 3:1• much higher risk abroad• mortality rate =
incidence
Above: Average yearly, age-adjusted incidence of HCC in US.
Left: Cumulative incidence of HCC among veteran patients between 1985 and 1990.
Gastroenterology 2004; 127: S27
Who gets HCC in the US?
• Hep C: 2-8% annual incidence
• Hep B: 0.5% annual incidence
• Cirrhosis due to other causes– EtOH, and others
(Wilson’s, α1AT-def, hemochromatosis, NASH)
Gastroenterology 2004; 127: S27-234
Diagnosis• History
– wt loss, early satiety = advanced mass
• Physical Exam– decompensation of cirrhosis
• ascites, jaundice, splenomegaly• bruit over liver?• paraneoplastic
• Labs– nonspecific, but indicative of
liver disease
• Alpha-fetoprotein– sensitivity/spec is poor
• Imaging– key point: U/S, CT, and
MRI all work well
• Biopsy– not always needed– risk of seeding (2.5 % in
one review)
Gut 2008; 57: 1592-6
Treatment of HCC1. Resectable or not2. Transplantable or not3. Small, local disease or
severe disease1. If small and local, can
pursue RFA, TACE (chemoembo), or PEA
2. If severe disease, pursue systemic therapy
1. Sorafenib vs. clinical trails
Am J Med 2007; 120: 194-202A simplified approach to treatment of HCC.
A word on surveillance….
There is no definitive evidence that screening for HCC improves survival*
USPSTF and ACS do not have guidelines for screening for HCC, but
the AASLD does.
…however, look for HCC when…Surveillance is recommended for the following groups of patientsHepatitis B carriers•Asian males > 40/females >50•Family history of HCC
•All cirrhotic Hep B carriers*•Africans >20
Non Hepatitis B cirrhosis•Hepatitis C•Alcoholic cirrhosis
•Genetic hemochromatosis•Primary billiary cirrhosis
Though at high risk, there is no data for Alpha 1- AT def, NASH, autoimmune hepatitis
Surveillance Plan for HCC• Alpha-fetoprotein
– at cutoff 20 ng/mL, 60% sens, 80% spec
– inadequate
• Ultrasound– sens 65-80%, spec 90%
• Interval– 6-12 months, but no data
• Use ultrasound to screen at 6-12 month intervals – (level II evidence)

Diagnosis
Hepatology 2005; 42: 1208-1233
Key Points
• HCC is increasing in incidence.• Screen selected patients with ultrasound q
6 months.• Select HBV carriers, HCV and others patients
with cirrhosis
• If the patient is symptomatic with HCC on presentation, the 5-year survival is 10%.
