Predictive Factors for the Post Embolization Fever after TACE for Hepatocellular Carcinoma Patients: A Single-Center Study in China.
Abstract Background Fever is one of the main symptoms for post-embolism syndrome (PES). This study aimed to determine and validate a model to predict fever after transcatheter arterial chemoembolization (TACE) in patients receiving platinum as the main regimen. Materials and Methods Clinical data of HCC patients who underwent TACE with platinum was retrospectively collected in the Fudan University Zhongshan Hospital during January 2016 to January 2018. According to post-TACE medical records, patients were divided into fever group and non-fever group. Predictive factors were selected by multivariate logistic regression. The receiver operating characteristic (ROC) curve were then performed to detect accuracy and discriminative ability of these factors using the derivation cohort and an independent validation cohort.Results Fevers were detected in 44 of 252 patients. Demographics, laboratory data were statistically similar within fever group and non-fever group. Strongest predictors identified in multivariate logistic regression included Iopiodol emulsion dose (OR, 1.081; 95%CI, 1.006-1.162), number of hepatoprotectants (OR, 0.619; 95%CI, 0.419-0.914), K+ (OR, 2.992; 95%CI, 1.225-7.308), and albumin-bilirubin (ALBI) grade (OR, 2.249; 95%CI, 1.040-4.862). Furthermore, the area under the ROC curve of derivation cohort and validation cohort were 0.798 and 0.874 respectively, which indicated comparative stability and discriminative ability of this model. Conclusions Iopiodol emulsion dose, number of hepatoprotectants, K+, and ALBI grade are strong predictors for PEF. The multivariate logistic model of these factors shows a discriminative ability to predict PEF in the validation cohort.
