Analysis of the Therapeutic Effect of Conformal Ablation Based on Artifi-cial Intelligence Assisted CT/MRI Image Fusion Technique for Residual Liver Cancer after TACE Procedure
Objective To analyze the residual effect and the incidence of complications of conformal ablation based on artificial intelligence(AI)-assisted CT/magnetic resonance imaging(MRI)image fusion techniques for residual liver canc-er after transcatheter arterial chemoembolization(TACE).Methods Sixty-one patients with residual liver cancer after TACE were selected from January 2019 to November 2023,and 30 patients(38 lesions)undergoing conformal ablation under the guidance of AI)-assisted CT/MRI image fusion techniques were selected as the observation group,and 31 patients(40 le-sions)underwent routine ablation were selected as the control group.The ablation conditions,the tumor markers[A-fetoprotein(AFP),carcinoembryonic antigen(CEA),carbohydrate antigen 125(CA125)]before ablation and at 1 month after ablation,liver function indexes[aspartate aminotransferase(AST)and alanine aminotransferase(ALT)]before ablation,at 24 h after ablation and 3 d after ablation were compared between the two groups.The complication rate and progression-free survival(PFS)were compared between the two groups.Results The ablation rate of immediate supplemen-tary ablation during operation,the ablation boundary during operation,and complete ablation in the observation group was higher than that of the control group,while the rate of incomplete ablation was lower than that of the control group(P＜0.05,P＜0.01).AFP,CEA and CA125 in the observation group were lower than those in the control group at 1 month after abla-tion(P＜0.05).AST and ALT in the observation group were lower than those in the control group at 24 h and3 d after abla-tion(P＜0.05,P＜0.01).There was no significant difference in the incidence of complications between the observation group[20.00%(6/30)]and the control group[32.26%(10/31)](P＞0.05),nor in the reablation rate between the ob-servation group[3.33%(1/30)]and the control group[16.13%(5/31)](P＞0.05).The PFS was loner in the observa-tion group than in the control group(P＜0.05).Conclusion AI-assisted CT/MRI image fusion technique can effectively improve the ablation effect of residual lesions after TACE,with good safety.
