- Repeated application of screening tests over time in order to reduce
disease-specific mortality
- Pts at risk / Eligible for treatment
- Final Result: Increased successful treatment and decreased disease
specific mortality

- Superior to AFP for detection of HCC
- Good availability
- Low cost
- No radiation
- Good patient acceptance
- Can assess patency of portal vein.
- BUT: User dependent
- Diagnostic efficiency continues to improve (Contrast enhanced / Echo
enhanced)

- AFP - no use for screening and only useful for confirmation of
diagnosis?
- Bolondi et al: AFP even >200 ng/ml : does not increase detection rate
of HCC in absence of nodules visible w/ US
- Combining US and AFP: Sensitivity 100%???

- Crucial to indicate treatment and achieve optimal outcomes.
- CT and MRI
- Indications for CT / MRI:
- Absolute AFP > 20 ng/ml
- Trend of Increasing AFP
- Lesion seen on US
- Inadequate US

- Sensitivities < 50% for detection of lesions smaller than 2 cm.
- Recently, the sensitivities and accuracy of MRI have shown improvement
for 1 cm to 2 cm sized nodules.
- Comparison of MRA with Helical CT showed better detection of all
nodules, esp. 1 – 2 cm nodules with MRI
- ( All: 76% vs 61% 1-2 cm: 84% vs 47%)
- Best MRI technology: Contrast-enhanced 3-D MRI with angiographic
sequences

- Cyto-histological criteria
- Non-invasive criteria (restricted to cirrhotic pts)

+ Angio)
- Focal lesion >2 cm with arterial
hypervascularization
- Combined criteria: one imaging technique associated with AFP
- Focal lesion >2 cm with arterial
hypervascularization
- AFP >400 ng/ml

- Option for few pts with HCC arising in a normal liver / well preserved
hepatic function.
- Proper selection, 5 year survival can be better than for OLT (70%)
- Segmentectomy / Subsegmentectomy
- Single, small tumor (<5cm)
- Bili <1
- Absence of Severe Portal HTN (<10mmHg)

- 97.5% Ethanol – induce coagulative necrosis
- Amount of ethanol correlates with cubic volume of tumor, with 1 cm rim
of normal tissue.
- Small encapsulated tumors with <3 in #
- No damage to remaining parenchyma
- Low Cost, Easy Operation
- Multiple treatment sessions and needle passes
- Painful

- Rising incidence in the US
- Surveillance: Q 6 mo to 1 year with at least one modality of imaging
- Only good prognostic factor is finding tumor early with small HCC and no
vascular invasion or portal vein thrombosis.
- Great survival benefit in Pts who get transplanted or resection in early
stage
