Direct-acting antiviral (DAA) therapy is not associated with increased overall or early hepatocellular carcinoma (HCC) recurrence, according to a large cohort of North American patients with complete response to HCC treatment. Researchers conducted a retrospective cohort study of patients with HCV-related HCC with a complete response to resection, local ablation, trans-arterial chemo- or radioembolization, or radiation therapy from January 2013 through December 2017 at 31 health systems throughout the US and Canada. They found:
- Of 793 patients with HCV-associated HCC, 304 (38.3%) received DAA therapy and 489 (61.7%) were untreated.
- HCC recurred in 128 DAA-treated patients (42.1%; early recurrence in 52 patients) and 288 untreated patients (58.9%; early recurrence in 277 patients).
- DAA therapy was not associated with HCC recurrence (HR, 0.90) or early HCC recurrence (HR, 0.96), after adjustments.
