Hepatic resection for two giant hepatocellular carcinoma after oral direct-acting antiviral therapy: Is there a relationship?

Mohamed Abdel Wahab, Ahmed Shehta, Mahmoud Ali


Introduction: Direct-acting antiviral drugs have been recently introduced for management of chronic hepatitis C virus (HCV) patients. Those medications have achieved a dramatic improvement of sustained virologic response (SVR) reaching almost 90%. However, reports regarding the increased risk of occurrence or recurrence of hepatocellular carcinoma (HCC) in chronic HCV patients who achieved SVR after direct-acting antiviral drugs are controversial.

Methods: We report two cases of giant HCCs complicating chronic HCV infection after direct-acting antiviral drugs-based therapies and were managed by major hepatic resection.

Results: Two male patients with chronic HCV infection received several regimens oral direct acting antiviral drugs with a SVR for 3 and 6 months, respectively. They complained of progressive right hypochondrial pain and abdominal enlargement. Two large HCCs were diagnosed (16.2 cm * 17.6 cm * 16.9 cm, and 18 cm * 13 cm * 16.5 cm in dimensions) with markedly elevated serum alpha feto-protein (36,000 and 7,000 ng/ml, respectively). Due to the presence of adequate residual liver volume, the decision was to proceed for surgical resection. Central hepatectomy and extended right hemi-hepatectomy were performed, respectively. Patients had smooth postoperative course and were discharged after 10 and 9 days, respectively.

Conclusion: The relationship between direct-acting antiviral drugs and HCC is controversial. Those cases add support to the accumulating literature suggesting the relationship of HCC development in chronic HCV patients receiving direct-acting antiviral drugs. Further prospective studies with adequate long term follow up are needed to prove or disprove this relationship.
