KPNA2 is a potential diagnostic serum biomarker for epithelial ovarian cancer and correlates with poor prognosis

摘要

This study aimed to determine whether serum karyopherin alpha 2 levels can be used as a diagnostic biomarker for epithelial ovarian carcinoma. Karyopherin alpha 2 protein was detected by enzyme-linked immunosorbent assay in serum samples from 162 epithelial ovarian carcinoma patients and 48 healthy controls. Serum karyopherin alpha 2 levels in epithelial ovarian carcinoma patients were significantly higher than in healthy controls ( p  485 µg/mL) correlated with International Federation of Gynecology and Obstetrics stage ( p  < 0.0001), lymphatic metastasis ( p  = 0.045), overall survival ( p  = 0.001), and disease-free progression ( p  = 0.006). Serum karyopherin alpha 2 represents a potential diagnostic biomarker for epithelial ovarian carcinoma.
