传统的宫颈鳞状上皮内病变的评判系统是根据病变的组织学特征将宫颈鳞状上皮内病变分为CINⅠ、Ⅱ、Ⅲ级,实践证明应用该标准评价时,不同观察者间的结果一致性较差。1988年美国癌症研究所建立了一种改良Bethesda分级系统,将宫颈鳞状上皮内病变分为正常、低度鳞状上皮内病变(LSIL)及高度鳞状上皮内病变(HSIL)。未成熟鳞状上皮化生、炎症不典型增生被视为正常。为评估应用该分 The traditional cervical squamous intraepithelial lesion evaluation system is based on the histological features of the lesion of cervical squamous intraepithelial lesions are divided into CIN Ⅰ, Ⅱ, Ⅲ grade, the practice proved that the application of the standard evaluation, the consistency between the results of different observers Poor. In 1988, the American Cancer Institute established a modified Bethesda classification system to classify cervical squamous intraepithelial lesions into normal low-grade squamous intraepithelial lesion (LSIL) and highly squamous intraepithelial lesion (HSIL). Immature squamous metaplasia, inflammatory dysplasia is considered normal. Apply this score for the assessment
