Liver Shorts: May 2019

ED Bethea et al. Clin Gastroenterol Hepatol 2019; 17: 739-47. Using a Markov-based mathematical model, the authors “found transplanting HCV-positive livers into HCV-negative patients with preemptive DAA therapy to a cost-effective strategy that could improve health outcomes.”

A Villanueva. NEJM 2019; 1450-62. This is a succinct review of hepatocellular carcinoma (HCC). Some points:

  • More than 1 million patients will die from liver cancer in 2030.
  • The rate of death from liver cancer increased 43% from 2000 to 2016,.  The 5-year survival rate is grim at only 18%.  Only pancreatic cancer is more lethal.
  • HCC is rare among patients without preexisting liver disease.  Cirrhosis is the main risk factor, though hepatitis B has direct oncologic effects even in the absence of cirrhosis.
  • The authors note that cancer surveillance has no “high-quality randomized controlled trials.” However, this may be due to difficulties with enrollment. In one study, 99%of patients declined to assume the risk of being randomly assigned to the nonsurveillance group. Nonetheless, mathematical models, and lower quality studies all show survival benefits of surveillance.
