宫颈上皮内瘤变(CIN)是局限在上皮内的具有向宫颈癌发展可能的一组癌前病变,随着宫颈细胞学的普查尤其是液基薄层细胞学检测、阴道镜下活组织检查、环切或锥切后病理检查三阶梯技术的广泛开展,使宫颈癌的检出率明显提高。人乳头瘤病毒感染,特别是高危型感染,是CIN发生的重要原因,也是其病变发展为宫颈癌的必要条件[1]。
Cervical intraepithelial neoplasia (CIN) is confined within the epithelium with the possible development of cervical cancer a set of precancerous lesions, with cervical cytological screening, especially liquid-based thin-layer cytology, colposcopic biopsy , Circumcision or conization after the pathological examination of the three ladder technology widely carried out so that the detection rate of cervical cancer significantly increased. Human papillomavirus (HPV) infection, especially at high risk, is an important cause of CIN and a necessary condition for its development as cervical cancer [1].
