Background: Patients with intermediate to advanced hepatocellular carcinoma(HCC) are most commonly treated with transarterial chemoembolization(TACE). Previous studies showed that TACE combined with recombinant human adenovirus type 5(H101) may provide a clinical survival benefit. In the present study, we aimed to determine the survival benefit of TACE with or without H101 for patients with intermediate to advanced HCC and to develop an e ective nomogram for predicting individual survival outcomes of these patients.Methods: We retrospectively collected data from 590 patients with intermediate to advanced HCC who were treated at Sun Yat?sen University Cancer Center between January 2007 and July 2015. After propensity score matching, 238 patients who received TACE with H101(TACE with H101 group) and 238 patients who received TACE without H101(TACE group) were analyzed. Overall survival(OS) was evaluated using the Kaplan–Meier method; the nomogram was developed based on Cox regression analysis. Discrimination and calibration were measured using the concordance index(c?index) and calibration plots.Results: Clinical and radiologic features were similar between the two groups. OS rates were significantly lower in the TACE group than in the TACE with H101 group(1?year OS rate, 53.8% vs. 61.3%; 2?year OS rate, 33.4% vs. 44.2%; 3?year OS rate, 22.4% vs. 40.5%; all P < 0.05). Multivariate Cox regression analysis for the entire cohort showed that alpha?fetoprotein level, alkaline phosphatase level, tumor size, metastasis, vascular invasion, and TACE with or without H101 were independent factors for OS, all of which were included in the nomogram. Calibration curves showed good agreement between nomogram?predicted survival and observed survival. The c?index of the nomogram for predict?ing OS was 0.716(95% confidence interval 0.686–0.746).Conclusions: TACE plus H101 extends the survival of patients with intermediate to advanced HCC. Our proposed nomogram provides individual survival prediction and stratification for patients with intermediate to advanced HCC who receive TACE with or without H101.

OS was 0.716 (95% confidence interval 0.686-0.746) .Conclusions: TACE plus H101 extends the survival of patients with intermediate to advanced HCC. Our proposed nomogram provides individual s urvival prediction and stratification for patients with intermediate to advanced HCC who receive TACE with or without H101.
