Conventional ethiodized oil transarterial chemoembolization for treatment of hepatocellular carcinoma: Contemporary single-center review of clinical outcomes

OBJECTIVE. The purpose of this study is to investigate the outcomes of conventional transarterial chemoembolization (TACE) treatment of hepatocellular carcinoma (HCC) in contemporary clinical practice. MATERIALS AND METHODS. In this single-institution retrospective study, 188 patients underwent conventional TACE for HCC between 2007 and 2013. Medical record and imaging review was used to collect baseline demographic and disease data, tumor response, time to progression (TTP), and progression-free survival (PFS) outcomes, as well as transplant-free survival, calculated from the time of the first conventional TACE treatment. Data were censored in April 2014. RESULTS. The study cohort included 140 men and 48 women (mean age, 60 years; Barcelona Clinic Liver Cancer [BCLC] stage 0 = 5%, BCLC stage A = 41%, BCLC stage B = 28%, BCLC stage C = 15%, and BCLC stage D = 11%) with 207 index tumors (mean size, 4.0 cm; 11% with portal vein invasion) treated with a mean of 1.6 selective (79%) or lobar (21%) conventional...
