The Role of Treatment Guidelines in HCC

Does it Matter Which Guideline We Use?

Hepatocellular Carcinoma (HCC) 5th most common cancer in men; 7th in women worldwide 2rd leading cause of death from cancer worldwide Incidence and death rate rising whereas many other cancer

mortality rates are decreasing Worldwide: Primarily due to Hepatitis B, C

In the US due to HCV and non-alcoholic steatohepatitis (NASH) Global HCC: Every 30 seconds, one person in the world dies from

liver cancer. > 80% of HCC cases occur in people from sub-Saharan Africa, S-E

Asia and eastern Mediterranean Recent therapeutic advances and continually updated expert

guidelines have improved the prognosis of HCC from a death sentence to a cancer that can be detected and treated at an early stage for good outcomes

What We Know About Treating HCC Staging patients is important

physiologic and anatomic

The only truly curative approach is surgery (resection or transplant). Most patients are not candidates for surgery

Chemoembolization (TACE/TABE) and microwave/radiofrequency ablation can improve survival in selected patients

Eventually most patients will require systemic/targeted treatment if they live long enough and their liver function remains stable

Cytotoxic chemotherapy has not had any impact on this disease

Sorafenib improves survival for patients with advanced HCC

4-phase CT scan reveals a 7-cm lesion between segments 1 and 4 near the portal vein, with classic arterial uptake and rapid washout consistent with HCC

Ascites was seen surrounding the liver; a small amount was seen in the pelvis.

How Do We Use AFP ?

AFP is a useful biomarker of a patient's increased future RISK for HCC.

AFP is not a screening or surveillance tool for HCC. AFP is not used to diagnose HCC. A high AFP or rising AFP is used to modify imaging algorithms. AFP can now be used in conjunction with lectin-reactive

alpha-fetoprotein (AFP-L3) and Des-gamma-carboxyprothrombin (DCP).

Bruix J, Sherman M. Hepatology. July, 2010. www.wakodiagnostics.com/hccbiomarkers.html.

AFP = alpha-fetoprotein; DCP = des-gamma-carboxyprothrombin;AFP-L3 = lens culinaris agglutinin A-reactive fraction of AFP.

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

Management of hand-foot skin reaction

38

Case Study: Multitargeted TKI ToxicityHand-Foot Skin Reaction

In one study, >90% of patients may experience skin reactions on multitargeted TKI therapy1

Incidence of hand-foot skin reaction was 21% in SHARP trial (all grades)2

Subsequent prospective clinical trials have found the incidence of reported hand-foot skin reaction as high as 60%1

1. Autier J et al. Arch Dermatol. 2008;144:886-892. 2. Llovet JM et al. N Engl J Med. 2008;359:378-390.


A. Immediate sorafenib discontinuation plus supportive care to address skin reaction

B. Sorafenib dose interruption for 1 week plus supportive care

C. Sorafenib dose reduction by 50% plus supportive care

D. Sorafenib dose reduction by 75% plus supportive care

E. Use supportive care to address skin reaction; alter dose after 1 week if no improvement

What is the next best step for treatment?

Case Study: Multitargeted TKI Toxicity Hand-Foot Skin Reaction

Typically develops within first 24 weeks of treatment and no later than day 45

Characterized by tender lesions that are scaling and have halo of erythema at pressure or flexure points

Later, areas of thickened skin develop

Lacouture ME et al. Oncologist. 2008;13:1001-1011.

Case Study: Grading and Management of Hand-Foot Skin Reaction

Grade Characteristics Management

1

Minimal skin changes or dermatitis

(eg, erythema)without pain

Avoid hot water Use moisturizing cream Consider keratolytics Wear cotton gloves/socks at night No dose reduction needed; follow-up within 2 weeks

2

Skin changes (eg, peeling,

blisters, bleeding, edema)

and/or pain, not interfering with daily activities

Employ grade 1 strategies Apply clobetasol ointment BID Use topical analgesics; use systematic analgesics only

after evaluating bleeding/kidney function If needed, consider 50% dose reduction for 728 days

until hand-foot skin reaction is grade 1/0, then full dose

3 Skin changes with

pain, interfering with daily activities

Employ grade 1/2 strategies Treatment interruption for 7 days until grade 1/0;

resume 50% of full dose and, if possible, escalate to full dose

Case Study: Prophylactic Options for Hand-Foot Skin Reaction

Perform full-body skin exam before initiation of therapy Emphasis on palms and soles

Pedicures to remove calluses and/or hyperkeratotic regions

Use of orthotic devices in patients with abnormal weight-bearing

Reduce hand/foot exposure to hot water

Encourage rest, avoidance of traumatic activity during early stages of therapy Avoid vigorous exercise during this time

Avoid constrictive footwear, friction to skin

Consider dietary changes2.3

Antidiarrheal agents if severe2.3

Fatigue (22% of patients in SHARP trial1)

Consult dietitian if nutrition intake is a concern2

Consider growth factors if anemia is found2

Consider modafinil or methylphenidate if severe3

Hypertension (5% of patients in SHARP trial1)

Encourage healthy lifestyle practices (diet, exercise)2

Start or adjust antihypertensives2.3

Conclusions Use of evidence-based treatment guidelines improves patient

outcomes.

Molecular targeted therapeutics will play a role in the future of HCC management.

Sorafenib has established a benchmark for front-line studies. Great unmet need for patients who are ineligible for, intolerant

to, and progress on sorafenib

Randomized Phase II trials are needed to better assess activity for moving agents into Phase III

Characterize promising new targets for therapy To better identify patients who will receive benefit
