Patient survival in HCV-positive and HCV-negative individuals. ONT/ RETH ( ) Hepatitis C recurrence after liver transplantation

65-year old patient with HCV-related liver cirrhosis An US examination reveals 2 HCC (3,5+1 cm diameter) After extensive evaluation the patient is included in the waiting list for liver transplantation. Treatment of hepatitis C in the waiting list of liver transplantation Genotype 1b IL28 CT; Viral load IU/mL Previous therapy with PegIFN and RBV in 2008: partial responder (> 2 log decrease in VL at week 12).

Should we treat this patient in the waiting list? Bilirubin 1 mg/dL, albumin 39 g/dL, platelets No ascites, transient elastography 19 kPa. What treatment would you propose? a) PegIFN + RBV b) PegIFN+RBV+PI (telaprevir/boceprevir) Treatment of hepatitis C in the waiting list of liver transplantation
