Predictors of liver failure after transarterial chemoembolization in patients with spontaneously ruptured
1Department of Hepatobiliary Surgery, The Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Background:
Spontaneously ruptured hepatocellular carcinoma (rHCC) is a life-threatening condition. Transarterial chemoembolization (TACE) is a widely accepted treatment; however, it can lead to serious complications, especially liver failure. We sought to identify preoperative predictors of liver failure in patients with rHCC undergoing TACE.
Methods:
Patients with rHCC who received TACE as the initial therapy were retrospectively studied at our institution between January 2016 and December 2021. Based on the occurrence of liver failure after TACE, the patients were divided into liver failure and no-liver failure groups. Predictors of liver failure after TACE were analyzed using univariate and multivariate regression analyses. The predictive performance was assessed using the area under the curve (AUC). Delong's test was used to compare predictive efficiency.
Results:
Sixty patients (19 and 41 in the liver failure and non-liver failure groups, respectively) were included. Multivariate analysis showed that preoperative prothrombin activity (PTA) level (odds ratio [OR], 0.956; 95% confidence interval [CI], 0.920-0.994; P = 0.024) and Child-Pugh grade B (OR, 6.419; 95% CI, 1.123-36.677; P = 0.037) were independent predictors of liver failure after TACE in patients with rHCC. The AUCs of the preoperative PTA levels and Child-Pugh grade B for predicting liver failure after TACE in patients with rHCC were 0.783 and 0.764, respectively.
Conclusion:
Preoperative PTA level and Child-Pugh grade B were significant independent risk factors for liver failure after TACE in patients with rHCC. These can be used to predict liver failure after TACE in patients with rHCC for individual decision-making regarding treatment planning.
