Hepatitis B virus status of black women with hepatocellular carcinoma.

abstract：BACKGROUND & AIMS:Little is known about substitutions that mediate resistance of hepatitis C virus (HCV) to direct-acting antivirals (DAAs), due to the small number of patients with treatment failure in approval studies. It is important to identify resistance patterns to select effective salvage treatments. METHODS:We...
