Influencing factors related to transcatheter arterial chemoembolization for hepatocellular carcinoma patients achieved tumor response

Objective: To investigate the influencing factors of transcatheter arterial chemoembolization (TACE) on patients with hepatocellular carcinoma (HCC) for tumor response (complete and partial response, CR + PR). Methods: This research conducted a retrospective study of the hospital charts of patients treated with TACE successfully renewed from October 2014 to December 2015 at Sun Yat-sen University Cancer Center (Guangzhou, China). Univariate analysis (Chi-square test and repeated-measures ANOVA) selected nine influential tumor response factors from 22 core factors. The nine variables were included in a forward multiple logistic regression model predicting patients treated with TACE to achieve tumor response. Overall survival was calculated using the Kaplan-Meier method. Results: Data of 277 of 282 patients were included in the analysis. Nine variables were analyzed by univariate analysis and independently associated with tumor response (tumor capsule integrity, nausea and vomiting, microwave ablation, liver dysfunction, the absolute value of lymphocyte (LYM), alpha-fetoprotein, and gamma-glutamyl transpeptidase (GGT). By multivariate analysis, GGT (odds ratio [OR] =0.996), liver dysfunction (OR = 0.395), combined with microwave ablation (OR = 0.503), and tumor capsule integrity (OR = 1.894) were the significant predictors of the tumor response group compared with the standard deviation group (P < 0.05). Conclusions: This study suggests that TACE combined with ablation on patients with complete tumor capsules may have a better prognosis in tumor response and OS; additionally, liver dysfunction and nausea and vomiting were the independent predictors of tumor response.
