Assessment value of X-ray angiography in postoperative recurrence,curative effect and the reduction of the perfusion of liver tumor of interventional TACE for liver cancer
Objective:To investigate the assessment value of X-ray angiography in postoperative recurrence,curative effect and reduction of the perfusion of liver tumor of interventional transarterial chemoembolization(TACE)for liver cancer.Methods:A total of 59 patients with liver cancer who were treated in The Third the People's Hospital of Bengbu from January 2015 to December 2020 were selected.All patients underwent the examination of routine X-ray angiography one week before surgery and four weeks after surgery.The obtained image sequences were imported into the workstation equipped with imaging technology software of color coded digital subtraction angiography(ccDSA)to conduct analysis.The region of interest(ROI)was manually defined on the ccDSA images before and after TACE.And then,the time intensity curve was obtained,and the quantitative perfusion parameters included the time to peak(TTP),area under curve(AUC),maximum slope(MS)were exported from that.The receiver operating characteristics(ROC)curve was drawn,and the area under curve(AUC)of that was calculated to analyze the assessment efficacy of perfusion parameters on the postoperative recurrence,curative effect and reduction of the perfusion of liver tumor of TACE for liver cancer.Results:In the 59 patients who were included in the study,39 cases occurred postoperative recurrence and 20 cases did not occurred postoperative recurrence according to the definition of postoperative recurrence,and the perfusion TTP(7.38±1.22)s of patients with postoperative recurrence was significantly lower than that(9.03±1.01)s of patients without postoperative recurrence,and the difference of that between them was significant(t=5.198,P<0.05).The AUC and MS of patients with postoperative recurrence were significantly lower than those of patients without postoperative recurrence(t=2.868,31.499,P<0.05),respectively.There were not significant differences in TTP,AUC and MS between patients with and without postoperative recurrence before surgery(P>0.05).According to the determination criteria of curative effect,35 cases were effectiveness,and 24 cases were ineffectiveness,and the postoperative TTP(9.09±1.08)s of patients with effectiveness was significantly higher than that(7.84±2.07)s of patients without effectiveness(t=3.029,P<0.05),and AUC and MS of patients with effectiveness were significantly higher than those of patients without ineffectiveness(t=3.852,54.366,P<0.05),and there were not significant differences in preoperative TTP,AUC and MS between patients with and without effectiveness(P>0.05),and the values of TTP,AUC and MS of the group with effectiveness and group without effectiveness after surgery were significantly higher than those before surgery,and the differences of them between two groups were significant(t=3.029,3.852,54.366,P<0.05),respectively.According to the grading criteria of subjective angiographic endpoints(SACE),33 cases were grade Ⅲ,and 26 cases were grade Ⅳ,and there were not significant in TTP,AUC and MS between patients with grade Ⅲ and patients with grade IV(P>0.05).The postoperative TTP,AUC and MS of patients with grade Ⅳ were significantly lower than those of patients with grade Ⅲ(t=7.679,3.498,58.968,P<0.05),respectively.The sensitivities of TTP,AUC and MS were respectively 66.70%,89.70% and 59.00% in assessing postoperative recurrence of interventional TACE for liver cancer,and the specificities of them were respectively 55.00%,55.00% and 55.00%,and the AUC values of them were respectively 0.629(95% CI:0.478-0.779),0.827(95% CI:0.723-0.931)and 0.512(95% CI:0.356-0.667).The sensitivities of TTP,AUC and MS were respectively 64.10%,79.50% and 61.50% in assessing postoperatively curative effect of interventional TACE for liver cancer,and the specificities of them were respectively 55.00%,65.00% and 55.00%,and the AUC values of them were respectively 0.609(95% CI:0.462-0.756),0.808(95% CI:0.698-0.918)and 0.580(95% CI:0.413-0.747).The sensitivities of TTP,AUC and MS were respectively 69.20%,82.10% and 53.80% in assessing the postoperative reduction of the perfusion of liver tumor of interventional TACE for liver cancer,and the specificities of them were respectively 70.00%,75.00% and 55.00%,and the AUC values of them were respectively 0.745(95% CI:0.613-0.877),0.842(95% CI:0.724-0.960)and 0.507(95% CI:0.360-0.654).Conclusion:The TTP,AUC and MS of perfusion parameters that are obtained by ccDSA quantitative analysis for the data after X-ray angiography examination have a certain application value in assessing the postoperative recurrence,curative effect and the reduction of the perfusion of liver tumor of interventional TACE for liver cancer.
