  1. Case Study Prasun K Jalal MD Baylor College of Medicine

  2. Case no. 1 • 53/M, Caucasian • Fatigue and lower extremity swelling- 6 m • H/O IV drug use in 1970’s • Drinks 2-3 beer a day for 20 yrs, stopped 6 m back

  3. Examination • BMI 35 • Spider angioma on chest • Hepatosplenomegaly • Trace pedal edema both legs

  4. Labs • Bili 2 (direct 0.5), Al Phos 70, AST 57, ALT 32, Alb 2.8, TP 7 • WBC 3.8, Hb 14, Platelet 84 • Creatinine 0.9, INR 1.2 • MELD=11 • HCV 1.1 million IU/ml, Genotype 1a

  5. Q1. What would you do next? • Liver Biopsy • US abdomen, screen for esophageal varices and Refer to a transplant center • Contrast enhanced CT scan or MRI, screen for esophageal varices and Refer to a transplant center \ • Serum AFP, screen for esophageal varices and Refer to a transplant center • Treat for Hepatitis C

  6. MRI 10/31/12 T2 Pre Arterial Equilibrium Venous

  7. Dual Blood Supply of Liver • The vascular supply of HCC arises from the hepatic artery through neovascularization. • Imaging of the liver has to be performed in a triple phase manner to account for the early arterial phase followed by the portal venous phase and the delayed phases Yu JS et al. Am J Roentgenol 1999

  8. Washout in HCC Washout in HCC Arterial phase 2-min delayed Arterial phase 5-min delayed

  11. HCV Cirrhosis and HCC HCV Cirrhosis and HCC (2-8% per year) Multiple smallfoci of HCC

  12. Groups for whom HCC surveillance in recommended or in whom the risk of HCC is increased, but in whom efficacyof surveillance has not been demonstrated- AASLD 2010 Surveillance recommended • Asian male hepatitis B carriers over age 40 • Asian female hepatitis B carriers over age 50 • Hepatitis B carrier with family history of HCC • African/North American Blacks with hepatitis B • Cirrhotic hepatitis B carriers • Hepatitis C cirrhosis • Stage 4 primary biliary cirrhosis • Genetic hemachromatosis and cirrhosis • Alpha 1-antitrypsin deficiency and cirrhosis • Other cirrhosis Surveillance benefit uncertain • Hepatitis B carriers younger than 40 (males) or 50 (females) • Hepatitis C and stage 3 fibrosis • Non-cirrhotic NAFLD

  13. AASLD Recommendations for HCC surveillance: Surveillance for HCC should be performed using ultrasonography (level II). Patients should be screened at 6 month intervals (level II). The surveillance interval does not need to be shortened for patients at higher risk of HCC (level III).

  14. Q2. What would you do next? • Biopsy the lesion • Refer to oncology-Chemotherapy with Sorafenib (Nexavar) • Surgical Resection of tumor • Evaluate for liver transplantation

  15. AASLD Guidelines for Diagnosis of HCC Liver Nodule (screening US) Growing/ Stable Changing Character Typical features of HCC = Hypervascularity on arterial phase AND washout in venous or delayed phases

  16. Surgical Resection In cirrhosis Surgical Resection: Indications • Child-Pugh A cirrhosis • No clinically significant portal hypertension • Bilirubin < 1 mg/dl • Plus: same criteria as in non-cirrhotics: • No macrovascular, lymph node, or extrahepatic metastases • Technical feasiblity • Tumors of any size

  20. Liver Transplantation for Small HCC: Milan Criteria Liver Transplantation for HCC: Milan Criteria • Patients with cirrhosis and HCC • Single tumors ≤ 5 cm or no more than 3 nodules, each ≤3 cm • No macrovascular invasion • No distant metastases • 75% 4-year survival, 83% recurrence-free • 27% exceeded criteria on path review • 50% 4-year survival, 59% recurrence-free Mazzafero, et al, NEJM 1996

  21. UNOS Criteria for Liver Transplantation for HCC • A candidate with an HCC tumor that is stage T2 may be registered at a • MELD/PELD score equivalent to a 15% probability of candidate death within 3 months. Stage T2 lesions are defined as • - 1 lesion >= 2 cm and <= 5cm; OR • 2 or 3 lesions, >= 1cm and <= 3cm in size. • Rule out any extrahepatic spread (i.e. lymph node involvement) and/or macrovascular involvement (i.e., tumor thrombus in portal or hepatic vein) with dynamic contrast enhanced computed tomography (CT) or magnetic resonance imaging (MRI). • The assessment of the candidate prior to transplant listing must include a CT of the chest that rules out metastatic disease. • The candidate must not be eligible for resection. • The alpha-fetoprotein level is required for all HCC exception applications.

  22. Expanding the Criteria for Liver Transplantation: UCSF Criteria 2001 Expanding the Criteria for Liver Transplantation: UCSF Criteria 2001 1 • Solitary lesion •  6.5 cm • Multiple •  3 nodules • Largest  4.5 cm • Total tumor diameter  8 cm Within criteria 0.8 0.6 Survival Distribution Function 0.4 Outside criteria 0.2 0 0 1 2 3 4 5 Years After Liver Transplantation Meet New Staging Criteria Yes: 60 49 37 25 20 16 No: 10 5 4 2 1 0

  23. Local Ablation Therapy for Transplant Candidates Local Ablation Therapy for Transplant Candidates • Can serve as “bridge” to transplant • Minimally invasive • Provides effective control of the tumor up to 1-2 year from the treatment • Additional benefit from tumor reduction prior to transplantation

  24. Q 3. What Loco-regional therapy you would recommend? • Percutaneous Ethanol Injection (PEI) • Radiofrequency ablation (RFA) • TransarterialChemoebmolization (TACE) • Radioembolization for Hepatocellular Cancer Using Yttrium-90

  25. TACE 11/26/2012

  26. Trans-arterial Radioembolization for Hepatocellular Cancer Using Yttrium-90 Impregnated Glass Microspheres • Evaluate hepatic arterial anatomy • Occlude any branches supplying extrahepatic structures • Infuse Tc-99m-macroaggregated albumin • confirm perfusion limited to the liver • measure the lung shunt (<16.5 mCi Y-90 to the lungs)

  29. A cohort Study of RFA demonstrated that complete ablation of lesion smaller than 2 cm is possible in more than 90% cases with a local recurrence rate of less than 1% McMahon BJ, Bulkow L, Harpster A, Snowball M, Lanier A, Sacco F, Dunaway E, et al. Hepatology 2000;32:842–846.

Factors Determining Prognosis of Hepatocellular Cancer Factors Determining Prognosis of Hepatocellular Cancer • Tumor stage • - Size - Vascular invasion • - Number - Extrahepatic spread • - Location • Liver function • Overall patient health • Performance status: Karnofsky score • Intervention-specific outcome Hepatocellular Cancer is a curable disease!
