宫颈上皮内瘤样病变(cervical intraepithelial neoplasia,CIN)是宫颈鳞状细胞癌的癌前病变[1],可分为3级:CIN1、CIN2和CIN3。虽然不典型增生的严重程度与进展到更高级别的CIN或宫颈癌存在某种关系,但宫颈癌也可以从CIN1发展而来,CIN2和CIN3并不总是进展为宫颈癌[2]。能够预测C Cervical intraepithelial neoplasia (CIN) is a precancerous lesion of cervical squamous cell carcinoma [1] and can be divided into three grades: CIN1, CIN2 and CIN3. Although the severity of atypical hyperplasia is associated with progression to higher levels of CIN or cervical cancer, cervical cancer can also develop from CIN1 and CIN2 and CIN3 do not always progress to cervical cancer [2].
