E7-ICC staining was advantageous in facilitating the secondary triage of HR-HPV-positive patients; therefore, this method can be used as an auxiliary scheme to routine LCT for diagnostic grading to improve the accuracy of cervical cytology.Conclusion: E7-ICC staining as a primary or auxiliary cytological screening scheme can effectively reduce the colposcopy referral rate.Keywords: cervical cancer, early screening for cervical cancer, cervical intraepithelial neoplasia, immunohistochemistry, HPV, E7 oncoprotein
