- W2921956298 abstract "Abstract Background To investigate the impact of direct-acting antivirals (DAA) and 12-week sustained viral response (SVR12) in patients with hepatocellular carcinoma (HCC) and chronic hepatitis C virus (HCV) infection. Methods Retrospective analysis of HCC patients diagnosed from 2005 to 2016 at an urban tertiary-care hospital. Kaplan-Meier curves and multivariable Cox proportional hazards models were used to assess survival. Results 969 patients met inclusion criteria. 478 patients received interventional oncology treatment (catheter-based therapies, ablation or combination locoregional therapies), 141 received supportive care (palliative or no treatment), 125 underwent liver transplantation, 112 had tumor resection and 94 received chemotherapy or radiation as their primary treatment. Median overall survival of the cohort was 24.2 months (95% CI: 20.9-27.9). 470 patients had HCV (56%). 123 patients received DAA therapies for HCV (26.2%), 83 of whom achieved SVR12 (68%). HCV-positive and HCV-negative patients had similar survival (20.7 months vs 17.4 months, p=0.22). Patients receiving DAA therapy had an overall survival of 71.8 months (CI: 39.5-not reached) vs 11.6 months (CI: 9.8-14.5) for patients without DAA therapy (p<0.0001). DAA patients who achieved SVR12 had an overall survival of 75.6 months (CI: 49.2-not reached) vs the non-SVR12 group (26.7 months, CI: 13.7-31.1, p<0.0001). Multivariable analysis revealed AJCC, Child-Pugh Score, MELD, tumor size, tumor location and treatment type had independent influence on survival (p<0.05). In HCV-positive patients, AJCC, MELD, tumor location, treatment allocation and DAA were significant (p<0.05). In patients receiving DAA therapy, only MELD and SVR12 were predictive of overall survival (p<0.05). Conclusions DAA therapy and achieving SVR12 is associated with increased overall survival in HCV patients with HCC. Summary Direct-acting antiviral use is associated with increased survival in hepatitis C-related hepatocellular carcinoma patients. Patients treated with direct-acting antiviral who achieved hepatitis C cure had additionally increased survival versus those treated with direct-acting antiviral who did not achieve hepatitis C cure. This study supports the use of direct-acting antiviral for hepatitis C treatment in hepatocellular carcinoma patients." @default.
