Background and Aims: For patients with intermediate-stage hepatocellular carcinoma (HCC), the definition of high tumor burden remains controversial. This study aimed to compare the prognostic value of different criteria of tumor burden in patients with intermediate-stage HCC undergoing transarterial chemoembolization (TACE). Methods: From 2007 to 2019, 632 treatment-naive patients with intermediate-stage HCC undergoing TACE were retrospectively enrolled. We compared different criteria of tumor burden in discriminating radiologic response and survival, including up-to-7, up-to-11, 5–7, 7 lesions criteria, and newly proposed 7–11 criteria. Results: The proportions of patients classified as high tumor burden were varied by different criteria. Among the 5 criteria, 7–11 criteria have the best performance to discriminate complete response (CR) and overall survival (OS) after TACE. In patients with low, intermediate, and high tumor burden classified by 7–11 criteria, the CR rate was 21, 12, and 2.5%, respectively (p < 0.001), and the median OS was 33.1, 22.3, and 11.9 months, respectively (p < 0.001). By multivariate analysis, 7–11 criteria were significantly associated with CR (intermediate vs. high burden, odds ratio = 4.617, p = 0.002; low vs. high burden, odds ratio = 8.675, p < 0.001) and OS (intermediate vs. high burden, hazard ratio = 0.650, p < 0.001; low vs. high burden, hazard ratio = 0.520, p < 0.001). Seven to 11 criteria also had the lowest corrected Akaike information...
