We will exclude patients who have known HCC or a suspicious appearing mass on imaging within six months prior to ascertainment of eligibility, as these patients require further diagnostic testing instead of routine screening. We will exclude patients with Child Pugh class C cirrhosis or other significant comorbid conditions with a life expectancy less than one year, (e.g., extrahepatic malignancy) because HCC screening is not recommended in these subgroups of patients.
