      Dr. Amit G Singal is an Associate Professor of Medicine and Medical Director of the Liver Tumor Program at UT Southwestern Medical Center. He received his Graduate Degree in Biology and Doctor of Medicine from the University of Michigan, Ann Arbor. He also earned two Master of Science degrees, the first from the University of Michigan in Health and Health Care Research and the second in Clinical Sciences from the University of Texas Southwestern in Dallas. Dr. Singal is Board Certified in Gastroenterology and Transplant Hepatology by the American Board of Internal Medicine. He is a member of several professional society committees and serves as Chair of the International Liver Cancer Association (ILCA) Surveillance and Biomarkers Special Interest Group. He is on the editorial board of several journals including Seminars in Liver Disease, Clinical Gastroenterology and Hepatology, Clinical Translational Gastroenterology, and PLOS Medicine. Dr Singal has published over 50 peer-reviewed scientific papers and over 20 review articles/textbook chapters on Hepatocellular Carcinoma.

    Abstract

    Hepatocellular Carcinoma (HCC), the third leading cause of global cancer mortality, continues to be a substantial burden to health systems, society and individuals at risk. Although prognosis is poor among most patients with HCC, with 5-year survival rates below 10%, frequent monitoring of at-risk patients is associated with improved early detection and survival rates. Patients with cirrhosis from any cause, including chronic hepatitis C, hepatitis B, and nonalcoholic steatohepatitis, may benefit from screening regimens, such as ultrasonography and serum biomarker monitoring. To date, abdominal ultrasound with or without alpha fetoprotein (AFP) is the preferred method for HCC screening in high-risk patients.

    Despite the relative low cost and non-invasive nature of these techniques, there is a potential opportunity to improve sensitivity and specificity of HCC detection by leveraging newly available serum biomarkers. PIVKA-II, also known as DCP, is a modified prothrombin that lacks the activity of interacting with other coagulation factors and is expressed in HCC cells. PIVKA-II has been used alongside ultrasound and AFP for HCC screening programs and HCC diagnosis in certain geographies (i.e. Japan).

    During this webinar we will review the epidemiological and clinical landscape of hepatocellular carcinoma. We will discuss current challenges and opportunities in HCC surveillance and patient management, including the role of biomarkers, including AFP and PIVKA-II.
