Correlation study of NF-κB, IER3, and recurrence of ovarian endometrioid cysts

Abstract Objective To investigate the expression of nuclear actor-k-gene binding(NF-κB) and immediate early response 3(IER3) in nuclear factor-activated B cells in ovarian endometrioid cysts. To analyze the correlation between the expression of NF-κB and IER3 and the recurrence of the ovarian endometrioid cyst. Methods From January 2018 to March 2019, a total of 80 patients who underwent laparoscopic ovarian cyst excision due to ovarian endometrioid cyst in the Department of Gynecology, Changzhou Maternal and Child Health Hospital were selected, including 40 patients without postoperative recurrence and 40 patients with recurrence, and the patients with recurrence were further divided into the primary recurrence and the secondary recurrence groups. The general clinical data of the patients were collected. The patient's Revised American Fertility Society (R-AFS) score, least function(LF) score, and endometriosis fertility index (EFI) were calculated, and immunohistochemical staining was performed to detect the expression of IER3 and NF-κB in the pathological tissues of the three groups. The receiver operating characteristic (ROC) curve was used to evaluate the predictive value of IER3 and NF-κB expression on postoperative recurrence of the ovarian endometrioid cyst. Cox proportional hazards model was fitted to analyze the related influencing factors of ovarian endometrioid cyst recurrence. Results The expression intensity of NF-κB was positively correlated with IER3 (P < 0.001). ROC curve showed that the area under curve (AUC) of NF-κB and IER3 combined diagnosis was 0.844, 95%CI was 0.754–0.933, sensitivity was 77.5% and specificity was 90.00%. Multivariate Cox survival regression showed that the IER3 expression intensity > 4.5 (HR = 4.661,95%CI: 1.712–12.690, P = 0.003) and the NF-κBexpression intensity > 4.5 (HR = 2.878,95%CI: 1.181–7.011, P = 0.020) were independent risk factor for postoperative recurrence, and EFI score (HR = 1.289,95%CI: 1.037–1.602, P = 0.022) was a protective factor for postoperative recurrence. Conclusion EFI score is a protective factor for postoperative recurrence, and the expression intensity of NF-κB and IER3 has a certain correlation with the recurrence of ovarian endometrioid cysts. The expression levels of NF-κB and IER3 > 4.5 are independent risk factors for postoperative recurrence.
