The treatment of hepatitis C virus (HCV) infection is possible in patients who have been successfully treated for hepatocellular carcinoma (HCC), and the best results were achieved with the use of multiple direct-acting antivirals (DAAs) and ribavirin (RBV), according to new findings published in the European Journal of Gastroenterology & Hepatology. However, HCC recurrence was noted to be high and was observed in 42% of patients. In this study group, 80.7% had recurrence within 6 months of treatment initiation.
Treatment of HCV in patients with advanced liver disease became a reality with the advent of DAA regimens. The current study describes the results of HCV treatment with DAAs in 62 patients with HCC who achieved a complete radiologic response after treatment of cancer.
Patients received one of 4 HCV treatment regimens: group 1 was given sofosbuvir (SOF)+RBV for 24 weeks, group 2 was given SOF+simeprevir for 12 weeks, group 3 received SOF+daclatasvir (DAC) for 24 weeks, and group 4 received SOF+DAC+RBV for 12 weeks.
The median follow-up was 12 months after treatment was initiated.
An overall response rate of 64.5% was achieved, with the highest rate seen with the SOF/DAC/RBV regimen for 12 weeks, at 87.5%, and the lowest was 26.7%, with 24 weeks of SOF/RBV.
The highest HCC recurrence rates were observed in patients treated with transarterial chemoembolization (66.7%) and the lowest was in patients treated with surgical resection or combined measures (0% for both, P =.04).
“Recurrence of HCC after DAA treatment is not an uncommon ﬁnding and more controlled trials are needed to clarify or deny the possible relationship,” write the authors.
