Objective:
We analyzed real-world data to elucidate the effects of anti-Hepatitis C virus (HCV) direct-acting antiviral (DAA) therapy on survival in patients with advanced hepatocellular carcinoma (HCC) and concomitant HCV infection treated with sorafenib.
Materials And Methods:
This population-based retrospective cohort study used the Taiwan National Health Insurance Research Database and the Registration System for Patients Treated with Oral Hepatitis C Antivirals to identify patients with advanced HCC and concomitant HCV infection who received initial targeted therapy (sorafenib) in 2018-2019. The overall survival (OS) of the DAA and non-DAA groups were compared using the Kaplan-Meier survival analysis. Propensity score matching was performed using a ratio of 1:4 to reduce confounding between the DAA and non-DAA groups.
Results:
The study included 1,684 patients (122 DAA and 1,562 non-DAA users) with HCC and concomitant HCV infection who used sorafenib for the first time in 2018-2019. The Kaplan-Meier survival analysis indicated that advanced HCC patients who used DAAs had longer OS compared to non-DAA patients. The mean survival times were 20.7 months for DAA and 12.5 months for non-DAA. Results obtained after propensity matching indicated a significant difference in OS between the DAA and non-DAA groups.
Conclusions:
The analysis of big data from the Taiwan National Health Insurance Research Database revealed that advanced HCC patients on sorafenib benefited from DAAs as a treatment for HCV infection. Patients whose HCV infection was cured had better OS.
