HCC: Epidemiology
HCC is the most common primary liver malignancy
Worldwide incidence >600,000 cases per year
– Liver cancer is the most rapidly increasing cancer in the U.S.
– 19,160 new cases and 16,780 deaths in 2007
More common in men than women (4:1)
For resection, rate of recurrence can be as high as 50% at 2 years
– Only 12% are eligible for resection or for transplant
– 80%-90% of HCC cases occur in cirrhotic livers

Background
In the United States and Europe, the majority of HCC develops in the setting of underlying liver cirrhosis
Treatment strategies for HCC should avoid worsening liver function to such an extent that would offset their possible benefit
Staging systems for treatment allocation, therefore, must concurrently consider tumor extension and severity of the underlying liver function impairment
There is no universally accepted staging system for HCC
The BCLC staging system for HCC is the most widely used in Western countries, particularly for treatment allocation

Screening and surveillance for HCC is the standard of care

•Screening: first test
•Surveillance: all subsequent testing – typically on a regular schedule

AASLD Practice Guidelines on Screening & Surveillance for HCC AASLD recommends surveillance using AFP + US every 6-12 months for at-
risk patient groups:
– Hepatitis B carriers
– Asian males >40 years
– Asian females >50 years
– All cirrhotic hepatitis B carriers
– Family history of HCC
– Africans >20 years
– Non-cirrhotic hepatitis B carriers with high HBV DNA levels or more severe current/past levels of inflammatory activity
– Cirrhosis due to hepatitis C, alcohol, or other causes

Screening/surveillance Current Strategies: US and AFP
US q 6-12 months and AFP q 6 months is the most commonly used strategy in Asia and U.S.
Rationale for 6-month screening/surveillance interval
– Doubling time: median = 6 mo (range, 1-19 mo)
– Growth from 1 to 3 cm: 4 mo for most aggressive, 18 mo for moderately aggressive, 5 yr for indolent HCC
Median detectable subclinical period for HCC = 3.2 yr

Making the diagnosis of HCC
Biopsy is very rarely indicated
– Risk of tracking tumor cells
– High false negative rate
Diagnosis is by imaging criteria

DIAGNOSTIC CRITERIA FOR HCC
EASL CONFERENCES ON HCC, BARCELONA 2005AASLD PRACTICE GUIDELINE, HEPATOLOGY 2005
• Cyto-histological criteria
• Non-invasive criteria (cirrhotic patients)
1. One imaging technique * Focal lesion > 2 cm with arterial hypervascularizationand venous wash-out
2. Two coincident imaging techniques * Focal lesion 1-2 cm with arterial hypervascularizationand venous wash-out
* Three techniques considered: contrast US, CT, and dynamic MRI

How do we use AFP ?
AFP is a useful biomarker of a patients increased RISK for HCC in the future
AFP is not a screening or surveillance tool for HCC

Ablation
RFA or TACE is/are the current standard(s)
PEI is for developing countries with limited resources
Microwave is faster to full tumor ablation but resources are expensive
Cryosurgery is no longer used due to length of time of procedure and complications of “ice ball”

Treatment: 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 prevents systemic absorption of chemotherapy agents and induces ischemic necrosis of tumor

Chemoembolization: Efficacy Before Transplantation Major issue: dropout rate (~ 20%)
– Lower in US since adoption of MELD criteria
Role of TACE
– Control tumor and prevent progression
– Should be considered if waiting time > 6 months
Complications from TACE: rare (no increased rate of hepatic artery complications)

Drug Eluting Beads
LC Bead is a Drug Delivery Embolisation System capable of loading and the controlled release of high doses of chemotherapeutic agents
– Doses per ml and per treatment:
– Doxorubicin maximum dose of 37.5mg/ml and 150mg/treatment with 4ml
Novel N-fil technology sulphonate modified hydrogel polymer
Blue tinted to aid visualisation
Delivered as vials containing 2ml Beads in 6ml saline
LC Bead is available in 3 sizes.
– 100-300um
– 300-500um
– 500-700um

Mechanism of Loading the LC Bead with Doxorubicin
The LC Bead has a negative charge where as doxorubicin has a positive charge…
The doxorubicin is loaded and eluted by an ‘reversible ionic exchange mechanism’.
Hydrated Beads
Hydration shell associated with PVA and ionic groups
Bulk (non-bound) waterInteraction of doxorubicin with SO3 groups displaces water from the hydration shells
Loaded Beads

90Yttrium vs. TACE
90Yttrium does not occlude the vessels at the arteriolar level
– Option for repeat embolic treatment
– Less ischemic damage
Response rates seem to be similar (no head-to-head comparisons)
Equivalent side effect profile
90Yttrium can be used in portal vein thrombosis and in more extensive disease

TACE accepted as treatment of choice for unresectable (nonablatable?) HCC
Prolonged survival established through randomized trials and prospective studies
Best vs good performance status, Child-Pugh class A-B
Role for yttrium-90 microspheres
Growing role for doxorubicin-loaded beads, pending outcome of clinical trials
