CYB5D2 and squamous cell intraepithelial neoplasia: Immunohistochemical detection of CYB5D2 protein outperformed ThinPrep cytology test (TCT), DNA aneuploidy analysis, and HR-HPV E6/E7 mRNA testing (mRNA expression of the E6 and E7 genes in high-risk HPV virus) in diagnosing high-grade squamous intraepithelial lesions (HSIL+) of the cervix.
