Abstract:
ObjectiveTo investigate the expression of RNA binding motif single stranded interacting protein 3 （RBMS3） in epithelial ovarian cancer （EOC） tissues and its relationship with the clinicopathological features and prognosis of EOC. MethodsThe study enrolled the paraffin-embedded tissues from 110 EOC cases and 73 benign epithelial ovarian tumor cases pathologically diagnosed in the first affiliated Hospital of Bengbu Medical College from January 2015 to December 2019. By using anti-RBMS3 polyclonal antibody， the immunohistochemical staining was employed to detect RBMS3 expression in the tissues and then its correlation with the clinicopathological parameters and prognosis of EOC was analyzed. ResultsRBMS3 was expressed in both EOC and benign epithelial ovarian tumor tissues. RBMS3 expression in EOC tissues， significantly related with International Federation of Gynecology and Obstetrics （FIGO） stage， histological grade， CEA levels and survival status， was significantly lower than that in benign epithelial ovarian tumor tissues （P<0.05）. Kaplan–Meier survival curve showed that low RBMS3 expression in EOC patients was correlated with decreased progression-free survival （PFS） and overall survival （OS） （P<0.05）. Univariate analysis showed that RBMS3 expression， FIGO stage， residual lesion size， intestinal metastasis and intraperitoneal implantation were associated with OS of EOC patients （P<0.05）； multivariate analysis showed that low RBMS3 expression and intestinal metastasis were independent risk factors for poor prognosis in EOC patients （P<0.05）. ConclusionsRBMS3 is expressed at low levels in EOC tissues， which is closely related to poor prognosis of EOC patients. RBMS3 may function as a tumor suppressor gene in EOC tissues and can be used as an EOC-independent prognostic marker for targeted therapy against EOC.
