Abstract: OBJECTIVE: To investigate expression levels of interleukin(IL)-17A and estrogen receptor α(ERα) and ERβ in epithelial ovarian cancer(EOC) tissues and their relationship with clinicopathological features and prognosis. METHODS: Clinical and pathological data of 102 EOC patients admitted to Wuxi Maternal and Child Health Hospital during August 2018-August 2022 were retrospectively analyzed. IL-17A, ERα, and ERβ mRNA expressions in cancer tissues and paracellular tissues were detected by real-time fluorescence quantitative PCR(qPCR), and the ERα/β ratio was calculated. The relationships between IL-17A m RNA, ERα/β and clinicopathological features were analyzed. Effects of IL-17A m RNA, ERα/β on the prognostic overall survival of EOC were analyzed by the Kaplan-Meier method and Cox regression analysis.RESULTS: Expressions of IL-17A, ERα and ERα/β were higher in the cancer than the paracancer tissues, while the expression of ERβ was decreased(P<0.05). The high and low expression groups of IL-17A and ERα/βwere divided by the mean values of 0.52 and 3.85, respectively, and the results showed that high IL-17A expression and high ERα/β ratio were associated with FIGO stage, lymph node metastasis, and the amount of ascites(P<0.05). The follow-up period ranged from 12 to 60 months, with a median follow-up period of 36 months, and a total of 38 cases(37.25%) died during the follow-up period. Kaplan Meier analysis showed that the cumulative survival rate of those with high IL-17A mRNA expression was lower than that of those with low expression(P<0.05), and the cumulative survival rate of those with high ERα/β ratio was lower than that of those with low ERα/β ratio(P<0.05). Multifactorial Cox analysis showed that FIGO stage III + IV, postoperative residual foci >2 cm, high expression of IL-17A mRNA, and high ERα/β ratio were independent risk factors for overall survival in patients with EOC(P<0.05). CONCLUSION: IL-17A, ERα and ERα/βwere up-regulated while the ERβ mRNA level was down-regulated in EOC, and the prognosis of EOC patients with high IL-17A expression and high ERα/β ratio was poor.
