Biomarkers for HCCBiomarkers for HCC
AFP: sensitivity 60-80%, specificity 70-90%
AFP-L3 isoform– AFP-L3 >10% total AFP associated with an
increased risk of HCC development
Golgi protein 73 (GP73)– More sensitive than AFP in detecting HCC in
preliminary studies
Des-gamma-carboxy-prothrombin (DCP)– Limited sensitivity in some studies for HCC < 3 cm
HCC-specific autoantibodies

Further Evaluation of Liver NodulesFurther Evaluation of Liver Nodules
<1 cm – Low likelihood of HCC– US every 3-6 months, revert to routine
surveillance if no growth over 2 years
>1 cm and < 2 cm– Treat as HCC if characteristic features on 2
dynamic studies (CT & MRI)– Biopsy if radiologic features are atypical
• Difficult to identify lesions < 2 cm by US• False negative rate >10%• Small risk of bleeding (<5%), rare tumor
seeding

Additional Imaging Techniques Additional Imaging Techniques
Contrast-enhanced ultrasonography (CEUS)– Uses microbubbles to detect hypervascularity
and characteristic washout of malignant lesions– Increases sensitivity and specificity of
conventional ultrasound
FDG-PET– Relatively low sensitivity for diagnosis of HCC,
particularly with well-differentiated tumors– May be useful for identifying extrahepatic
metastases including involvement of the lung, bone, and lymph nodes

Therapy: Surgical ResectionTherapy: Surgical Resection
Solitary HCC– Normal bilirubin– Absence of significant portal hypertension
• HVPG <10 • (esophageal varices, ascites, or
splenomegaly with plt <100,000)
Perioperative mortality 1-3%
5 year survival: up to 70%
Recurrence: 50% at 3 years, 70% at 5 years

Ablative TherapyAblative Therapy
Radiofrequency ablation (RFA)– 90% CR for lesions <3 cm– Not optimal for larger lesions or tumors near the
hilum or large vessels– AE: hemorrhage, infection/abscess, gallbladder
injury, liver failure
Transarterial chemoembolization (TACE)– Direct drug delivery + ischemic necrosis– Improves 2-year survival for unresectable HCC– AE: abdominal pain, nausea, fever,
infection/abscess, gallbladder injury, liver failure

TACE + RFA for Large HCCTACE + RFA for Large HCC
RCT of 291 patients with HCC >3 cm
Rationale: reducing tissue perfusion by TACE → ↓ heat loss, ↑efficacy of TACE
Survival benefit for TACE+RFA
– Overall, single, multiple lesions

Radiation TherapyRadiation Therapy
Yttrium (90Y) radioembolization– Microscopic embolization with glass beads
– T1/2 65.4 hours, path length 5.3 mm
– Delivered selectively, segmentally, or diffusely– Safe with branch/lobar portal vein thrombosis– AE: radiation pneumonitis, GI bleeding, liver
failure
Focused high dose RT– Made possible by advances in RT planning, image
guided therapy, respiratory tracking– Radiation sensitizing agents– Particle therapy (protons or carbon ions)

Liver TransplantationLiver Transplantation
Milan: single tumor <5 cm or up to 3 tumors (none >3 cm), without vascular invasion or extrahepatic spread
– 5-yr post-transplant survival >70%
USCF: Single tumor < 6.5 cm or < 3 tumors, largest < 4.5 cm with total diameter < 8 cm
– 2-yr survival 86% (95% CI 54-96%)
Sirolimus might impact on recurrence

SummarySummary
The incidence of HCC is increasing in the US
Diagnosis and management require a multidisciplinary approach
Surveillance consists of ultrasound every 6-12 months in at risk patients
Diagnosis often made by noninvasive criteria
Ablative therapy improves survival and can serve as a bridge to transplant
Transplantation can be curative in selected cases
