Clinical significance of miR-139-5p and FGF2 in ovarian cancer.

PURPOSE To estimate the expression and clinical significance of miR-139-5p and fibroblast growth factor 2 (FGF2) in ovarian cancer (OC). METHODS Of the 198 female patients undergoing surgical treatment in our hospital, 101 patients with ovarian tumor resection were allocated in a study group and 97 with ovarian resection for benign lesions were allocated in a control group. MiR-139-5p and FGF2 expression was quantified, and associations between miR-139-5p and FGF2 and clinicopathological features of OC were analyzed, as well as their diagnostic performances (receiver operating characteristic (ROC) curve). RESULTS The study group presented lower miR-139-5p level and higher FGF2 level (both p<0.05). Significant associations of miR-139-5p and FGF2 with tumor differentiation and clinical stage were noted in OC (p<0.05). MiR-139-5p was reversely associated with clinical stage and positively associated with tumor differentiation (p<0.05), FGF2 was positively correlated with clinical stage and negatively correlated with tumor differentiation (p<0.05). The overall survival in the study group was 70.41%. The survival in high miR-139-5p expression group and low FGF2 expression group improved remarkably (p<0.05). The area under the curve (AUC) of combined detection (0.91) was higher than that of single detection. CONCLUSION MiR-139-5p shows a decreased expression and FGF-2 shows an increased expression in OC, and they are associated with clinical stage and tumor differentiation. Combined detection of miR-139-5p and FGF-2 contributes to the diagnosis and treatment of OC, and is an available biomarker for the diagnosis and prognosis of patients.
