HCC Surveillance

Is Surveillance “Worthwhile”?

How do we define “worthwhile”?

– Improvement in survival of 3 months[1]

Surveillance considered cost-effective if it achieves this 3-month improvement in survival at a cost of < $50,000 per life-year saved[2]

1. Naimark D, et al. J Gen Intern Med. 1994;9:702-707. 2. Laupacis A, et al. CMAJ. 1992;146:473-481.

Surveillance for HCC

Objective

– To reduce mortality from HCC

A single randomized controlled trial of 18,816 people with HBV infection or history of chronic hepatitis in urban Shanghai, China enrolled

– Surveillance group offered US and AFP every 6 months (n = 9373)

– Control group received no surveillance (n = 9443)

– surveillance hepatitis B carriers with semiannual AFP and US reduces HCC-related mortality by 37%

Zhang BH, et al. J Cancer Res Clin Oncol. 2004;130:417-422.

Identification of At-Risk Population for HCC Surveillance What level of risk makes surveillance worthwhile?

– Incidence

According to randomized controlled trials

– Hepatitis B: 0.28% per year[1]

According to cost-efficacy analyses

– Hepatitis B: 0.2% per year[3]

– Non-hepatitis B cirrhosis: > 1.4% per year[4]

1. Zhang BH, et al. J Cancer Res Clin Oncol. 2004;130:417-422. 2. Sarasin FP, et al. Am J Med. 1996;101:422-434. 3. Morris Sherman, MB BCh, PhD, FRCP(C). Data on file. 4. Arguedas MR, et al. Am J Gastroenterol. 2003;98:679-690.

The Benefit of Surveillance

For HCC incidence of 1.5%/ year, → survival increases for 3 months after surveillance

For HCC incidence of 6%/year → increase of 9 months.

Cost-effective -when the incidence of HCC > 1.4%. .

Recommendation :Surveillance for risk of HCC >=1.5%/year

HCC Surveillance by CT Scan

No evidence to support the use of CT scanning for routine HCC surveillance

– PPV and NPV unknown

– Accurate use of CT requires 4-phase contrast CT

– Radiation exposure is significant

– In the absence of contrast CT, false-positive rate very high

– Cannot distinguish small HCC from dysplastic nodules or arterialized cirrhotic nodules

– Flow abnormalities create diagnostic difficulty

Standard angiography and CTAP angiography

Contrast enhanced ultrasound (CEUS) could also be used for this non-invasive diagnosis.

Other radiological tests. In particular lipiodol angiography is not sensitive for small HCC.

Standard angiography and CTAP( arterioportal angiography) should not be routinely performed.

AASLD and NCCN Surveillance Guidelines

AASLD Guidelines

Surveillance recommended in at-risk groups

– Specific hepatitis B carriers

– Nonhepatitis B cirrhosis

US preferred surveillance tool

– AFP alone should not be used unless US unavailable

Patients should be screened at 6- to 12-month intervals

NCCN Guidelines National Comprehensive Cancer Network

(21家世界頂級癌症中心組成的非營利性學術聯盟 )

US and AFP, AP, and albumin for surveillance in high-risk patients

– Every 3-6 months

Continue screening every 3 months in those with high AFP but no evidence on imaging

Japan Society of Hepatology (JSH) - 2007Consensus-Based Clinical Practice Manual

Population at Risk for HCC

Summary

At-risk patients should be screened for HCC

Ultrasound surveillance is preferable

– AFP increased the detection rate

Surveillance should take place at 3-6-month intervals for high risk patients

– Evidence for better survival than 12-month intervals

Diagnosis of Hepatoma

EASL conference on HCC diagnosisTumors>2 cm

The diagnosis of HCC can be made without biopsy :

In Cirrhotic patients who have a mass> 2 cm that shows characteristic arterial vascularization on two imaging modalities,

- Triphasic CT scan and MRI.

The positive predictive value of the clinical and radiological findings exceeds 95%

Tumors 1-2 cm in diameter

Lesions between 1-2 cm in a cirrhotic liver have a high likelihood of being HCC.

These lesions should be biopsied irrespective of their vascular profile

Biopsy of small lesions (2 cm) may not be reliable

Needle placement may be difficult

D.D. Dysplasia and well-differentiated HCC

Lesions Less Than 1 cm in Diameter

Low likelihood of being HCC

Malignancy is even less likely if they do not show contrast uptake on dynamic imaging

Even if CT or MRI show tiny nodules with arterial vascularization. They may not correspond to HCC foci.

Need to be followed-up every 3-6 months. (level III).

Lack of growth over a period of more than 2 years suggests that the lesion is not HCC

Recommendations

if the vascular profile on imaging is not characteristic or if the nodule is detected in a non-cirrhotic liver,

-- Biopsy should be performed (level II).

Biopsies of small lesions should be evaluated by expert pathologists. If the biopsy is negative for HCC patients should be followed by ultrasound or CT scanning at 3-6 monthly intervals

If the lesion enlarges but remains atypical for HCC a repeat biopsy is recommended (level III).

Diagnosis in High Risk Patients

Atypical Image on Dynamic CT/MRI(JSH)

When a lesion is intensely enhanced in the early arterial phase and becomes low-attenuation in the equilibrium phase,,

R/O FNH and A-P shunt,

Uptake by Kupffer cells is investigated by

1.SPIO (superparamagnetic iron oxide -enhanced MRI )

2.Sonazoid-enhanced ultrasonography.

When high SPIO-enhanced MRI signals or a defect in the

Kupffer phase of Sonazoid-enhanced ultrasonography

are confirmed, the lesion is diagnosed as HCC

Tumor Staging

Currently there are 3 staging systems for HCC:

(1) TNM staging as tumor spreading staging,

(2) liver function staging

(3) systems integrating (1) and (2). For TNM staging,

Staging System

UICC( international union against cancer) or AJCC (American joint

committee on cancer) classification is used internationally (2005)

These are thought inappropriate because the cut-off tumor size is set to 5 cm (JSH)

Portal microinvasion and intrahepatic metastasis occurs in 27% and 10% of tumors with a tumor size of 2 cm or more

(4) SPIO-MRI [24, 25]

The Risk of HCC in Patients with Chronic Hepatitis C

In cirrhotic patients, the incidence 2%-8% / year.

Anti-HCV-positive conferred a 20-fold increased risk of HCC (12,008 men)

Surveillance for cirrhosis or bridging fibrosis or transition to cirrhosis.

Staging system CLIP scores or BCLC stages are used in Europe and North America as

staging systems.

the BCLC stage is basically a treatment selection system for deciding on a therapeutic strategy,

CLIP and JIS scores are prognostic prediction stagings.

The CLIP score and BCLC stage tend to detect relatively large HCCs,

JIS score is most useful for countries where many

small liver cancers are detected.

Interferon & Lamivudine

No convincing evidence that interferon treatment of chronic hepatitis B reduces the incidence of HCC.

A single RCT suggests that lamivudine treatment reduce the incidence of HCC

in HBV-related cirrhosis ??

Hepatitis C treated with interferon

A single RCT in Japan suggested that

the incidence of HCC was reduced in both responders and non-responders

In a meta-analysis, benefit is mainly seen in sustained virological responders, and

the effect was small.

Recommendations

17. Local ablation is safe and effective therapy for

patients who cannot undergo resection, or as a bridge to transplantation (level II).

18. Alcohol injection and radiofrequency are

equally effective for tumors <2 cm. However, the

necrotic effect of radiofrequency is more predictable in all tumor sizes and in addition, its efficacy is clearly superior to that of alcohol injection in larger tumors (level I).

Surgical Recommendations

Recommendations

Patients who have a single lesion can be offered surgical resection if they are non-cirrhotic or have cirrhosis but still have well preserved liver function,

normal bilirubin and

hepatic vein pressure gradient <10 mmHg (level II).

Pre or post-resection adjuvant therapy is not

recommended (level II)

Largest Prospective Study of TACE for Unresectable HCC to Date N = 8510 patients

Primary endpoint: OS

Multivariate analysis conducted of factors affecting survival

– Year 1: 82%; Year 3: 47%; Year 5: 26%; Year 7: 16%

– OS better with lesser degree of liver damage

Factors affecting survival

– Child-Pugh stage

– TNM stage (OS better with stage I, increasingly worse progressing toward stage IV)

– Alpha-fetoprotein level

Takayasu K, et al. Gastroenterology. 2006;131:461-469.

Embolization: Summary

Well-performed comparative studies between chemoembolization, radioembolization, and bland embolization needed

Chemoembolization has longest “track record” and data suggest survival advantage

Radioembolization data rapidly accumulating

– Advantages include lack of induction of ischemia, outpatient procedure without postembolization syndrome

Bland embolization

– Response demonstrable but not clear if benefits in cost; questionable benefits in toxicity outweigh likely decreased response

– Potential role (especially niche role, such as in patients with poor hepatic function or in combination with ablative therapy) remains to be proven

Transarterial Embolization and Chemoembolization Recommendations

19. TACE is recommended as first line non-curative

therapy for non-surgical patients with large/multifocal

HCC who do not have vascular invasion or extrahepatic

spread (level I).

20. Tamoxifen, antiandrogens, octreotide or hepatic

artery ligation/embolization are not recommended

(level I).

Chemoembolization: Predictors of Survival Lo et al[1]

– Absence of presenting symptoms (ECOG PS < 2)

– Absence of portal vein obstruction

– Tumor size (≤ vs > 5 cm)

– Okuda stage (I vs II)

Llovet et al[2]

– Absence of constitutional syndrome (ECOG PS < 2)

– Low serum bilirubin

– Treatment response (modified WHO criteria, > 6 months)

– > 3 cm

– Ideal surveillance interval unknown

– Tumor growth rates suggest every 4-12 months

Does not depend on degree of risk
