Objective To investigate the value of secreted frizzled-related protein 1(SFRP1),GATA binding protein 3(GATA3)combined with human papillomavirus deoxyribonucleic acid(HPV-DNA)in predicting the risk of postoperative recurrence of high-grade cervical intraepithelial neoplasia(CIN)with positive thin-prep cytologic test(TCT).Methods A total of 200 patients with high-grade CIN and positive TCT results from July 2021 to July 2023 were selected as study subjects.All patients underwent cervical conization,and were divided into recurrence group and non-recurrence group according to the recurrence status one year after surgery.The clinical data,HPV-DNA viral load,and the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cer-vical tissues were compared between the two groups.The HPV-DNA viral load,SFRP1 mRNA,and GATA3 mRNA expression levels in patients with different CIN grades were compared,and their cor-relations with CIN grade and the risk of postoperative recurrence were analyzed.The predictive val-ues of SFRP1,GATA3,and HPV-DNA for the risk of postoperative recurrence were analyzed.Results Among 200 patients,2 were lost during the follow-up period.The recurrence group(n=30)had higher proportions of CIN grade Ⅲ,glandular involvement,positive surgical margins,high-risk human papillomavirus(HPV),higher HPV-DNA viral load,and a higher proportion of HPV positivity at 6 months after surgery compared with the non-recurrence group(n=168),and the differences were statistically significant(P＜0.05).The relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues of the recurrence group were lower than those of the non-recur-rence group,and the differences were statistically significant(P＜0.001).The HPV-DNA level in pa-tients with CIN grade Ⅲ was higher than that in those with CIN grade Ⅱ,and the relative expres-sion levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were lower than those in patients with CIN grade Ⅱ,and the differences were all statistically significant(P＜0.001).Spearman cor-relation analysis showed that HPV-DNA was positively correlated with CIN grade(P＜0.001),while the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were neg-atively correlated with CIN grade(P＜0.001).Logistic regression analysis showed that HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were independ-ent influencing factors for the risk of postoperative recurrence(P＜0.001).The receiver operating characteristic(ROC)curve results showed that the areas under the curve(AUCs)for predicting the risk of postoperative recurrence by HPV-DNA,the relative expression levels of SFRP1 mRNA and GATA3 mRNA in cervical tissues were 0.787,0.781,and 0.764,respectively,with sensitivities of 80.00％,76.67％,and 76.67％,and specificities of 74.40％,73.81％,and 67.26％,respec-tively.The AUC for the combined prediction of the risk of postoperative recurrence by the three indica-tors was 0.924,with a sensitivity of 80.00％and a specificity of 93.45％,which was superior to the pre-dictive values of each indicator alone(Z=3.159,3.306,4.018,P＜0.001).Conclusion HPV-DNA,SFRP1,and GATA3 in cervical tissues have certain predictive values for the risk of postoperative re-currence in patients with high-grade CIN and positive TCT results,and combined detection can im-prove the predictive efficacy.
