This study developed and validated a nomogram for predicting the prognosis of patients with ruptured hepatocellular carcinoma (HCC) undergoing transarterial chemoembolization (TACE) treatment. The study identified total bilirubin (TBIL) levels and diameter of the largest tumor as independent prognostic factors for predicting overall survival (OS) in ruptured HCC. The newly developed nomogram can help evaluate the approximate survival rates based on tumor diameter and TBIL level after TACE treatment.
Background: Although transarterial chemoembolization (TACE) has been widely used for treating the spontaneous rupture of hepatocellular carcinoma (HCC), no existing model exists for predicting survival. The aim of this study was thus to develop and validate a nomogram for estimating the prognosis in patients with ruptured HCC upon undergoing TACE treatment. Methods: This study included 55 patients with spontaneously ruptured HCC who underwent TACE treatment between January 2015 and April 2019. The diagnosis of spontaneous HCC rupture was based on the disruption of the peritumoral liver capsule with surrounding fluid in the perihepatic region. The prognostic nomogram was constructed using the independent predictors assessed by the multivariate Cox proportional hazards model. Results: The median overall survival (OS) was 6.4 months, with 6-month and 1-year survival rates of 52.7% and 41.8%, respectively. In the univariate analysis, the size of the largest tumor, total bilirubin (TBIL) levels, and aspartate aminotransferase (AST) levels were associated with the OS of patients. Multivariate analysis suggested that TBIL levels (HR =0.358, P=0.036) and diameter of the largest tumor (HR =1.012, P=0.044) were independent prognostic factors for predicting the OS. Based on these variables, we developed and validated a nomogram for the risk stratification of HCC rupture after TACE treatment for individual patients. According to the nomogram risk assessment, we were able to evaluate the approximate 1- and 2-year survival rates based on patients' tumor diameter and TBIL level after TACE treatment of ruptured HCC. The concordance index for the OS prediction was 0.748 (95% CI: 0.691-0.805). This newly developed nomogram represents an intuitive tool for predicting the OS of patients with ruptured HCC. Conclusions: This study indicated that TBIL levels and diameter of the largest tumor were independent prognostic factors for predicting the OS of ruptured HCC. This study may help maximize favorable TACE treatment outcomes.
