子宫颈上皮内瘤变(cervical intraepithelial neoplasia,CIN)是与子宫颈浸润癌相关的一组癌前病变,能反映子宫颈癌发生发展中的连续过程。研究表明,CIN具有两种不同的生物学行为:其一是由病毒引起的病变,常自然消退,很少发展为浸润癌;另一种是多因素(包括病毒)诱发的病变,具有 Cervical intraepithelial neoplasia (CIN) is a group of precancerous lesions associated with invasive cervical cancer, which can reflect the continuous process in the development of cervical cancer. Studies have shown that CIN has two distinct biological behaviors: one is a disease caused by a virus that often subsides spontaneously and rarely progresses to invasive carcinoma; the other is a multifactorial (including viral) -induced lesion with
