Purpose: To evaluate the clinical implications of initial and best responses during repeated transarterial chemoembolization procedures for hepatocellular carcinoma (HCC). Materials and Methods: This study included 726 patients who received a diagnosis of intermediate-stage HCC with Child-Pugh class A liver function between 2007 and 2016, and who were treated with transarterial chemoembolization as the first-line treatment. Evaluation of treatment response was based on the modified response evaluation criteria in solid tumors. Overall survival (OS) was compared between response categories after implementation of landmark analysis. Results: Of the 726 patients, an objective response (complete response [CR] or partial response [PR]) was observed as the initial response in 78.1% of patients. Regarding the best response during the transarterial chemoembolization series, 87.2% of patients were overall responders. The median OS of initial responders (n = 483) was not significantly different from that of subsequent responders at the 1-year landmark (stable disease [SD] after first transarterial chemoembolization but CR or PR after repeated transarterial chemoembolization; n = 61; 46.2 vs 40.1 months, respectively; P =.145). Likewise, the median OS of initial CR patients (n = 326) was not significantly different from that of the subsequent CR group (n = 126) at the 1-year landmark (PR or SD after first transarterial chemoembolization but CR after repeated transarterial chemoembolization; 53.4 vs 46.3 months, respectively; P =.455). Multivariate Cox analyses showed that the objective responses, the initial responses (hazard ratio [HR], 0.638; P =.001), and the best responses (HR, 0.304; P <.001) had the significant prognostic significance for OS. Conclusions: Both the initial and best responses during repeated transarterial chemoembolization were significantly associated with OS in patients with intermediate-stage HCC and preserved liver function.
