The Safety and Efficacy Profile of TACE for Treating Hepatocellular Carcinoma in Patients Co-infected with HIV and HCV: A Propensity Score Matching Study
Wednesday, Dec. 2, 12:15-12:45 p.m., Vascular Interventional (VI) Community, Learning Center, Station #4
Hepatocellular carcinoma (HCC) is becoming an increasing cause of morbidity and mortality in patients co-infected with HIV and HCV. Transcatheter arterial chemoembolization (TACE) is an important treatment option for unresectable HCC, but to date, there is insufficient data on the safety and efficacy profile of TACE in this specific cohort. In this study, researchers compare HCC patients with HIV/HCV co-infection treated with TACE against HCC patients with HCV mono-infection treated with TACE through survival analysis and recording of major complications.
