Résumé
Objective:To study the risk factors of patients with hepatocellular carcinoma (HCC) to transcatheter arterial chemoembolization(TACE) refractoriness.Methods:The clinical data of 106 HCC patients who underwent TACE at the Affiliated Hospital of Xuzhou Medical University from January 2020 to December 2021 were retrospectively studied. There were 90 males and 16 females, with the age of (59.9±9.3) years. These patients were divided into the TACE-refractory group ( n=47) and the control group ( n=59) based on whether TACE refratoriness occurred after surgery. Serum alpha-fetoprotein (AFP), protein induced by vitamin K absence or antagonist-II (PIVIKA-II), maximum diameter of tumor, number of tumor and tumor vascularization patterns between the two groups were compared. Multivariate logistic regression analysis was performed to analyse the risk factors of TACE refractoriness in patients with HCC after TACE. Results:The proportion of patients with AFP >400 μg/L, PIVIKA-II >40 AU/L, number of tumor and tumor vascularization patterns Ⅲ+ Ⅳ (uneven enhancement) were significantly higher in the TACE-refractory group than the control group (all P<0.05). The maximum diameter of tumor for patients in the TACE-refractory group was significantly larger than that in the control group ( Z=-2.41, P=0.016). Multivariate logistic regression analysis showed that patients with serum AFP >400 μg/L( OR=2.707, 95% CI: 1.008-7.271), multiple tumors ( OR=6.069, 95% CI: 2.115-17.415) and tumor vascularization patterns Ⅲ+ Ⅳ (uneven enhancement)( OR=7.813, 95% CI: 2.246-27.176) before the first TACE were at increased risks of TACE refractoriness (all P<0.05). Conclusion:Preoperative AFP >400 μg/L, multiple tumors and tumor vascularization patterns Ⅲ+ Ⅳ were independent risk factors for TACE refractoriness in patients with HCC.
