子宫颈鳞状上皮肉瘤也称不典型增生和原位癌。各级上皮肉瘤的预后是不一致的,因此其病理分级诊断对判断预后和指导临床治疗具有十分重要的价值。分级诊断的标准虽在形态学方面描述得比较准确一致,但在实际应用中对某些病例往往难以分级。我们试图应用分级明确的典型病例对一些形态学标准进行定量描述,从中找出一些有意义的参数从定量的角度进行分级。在以前的报导中我们已介绍了以核面积为中心的参数,本文将介绍反映核形状及排列的参数。 Cervical squamous cell sarcoma, also known as atypical hyperplasia and carcinoma in situ. The prognosis of epithelial sarcoma at all levels is inconsistent, so the pathological grading diagnosis is of great value in judging prognosis and guiding clinical treatment. Although the classification of diagnostic criteria described in the morphology is more accurate and consistent, but in practical applications of some cases are often difficult to grade. We attempt to quantify some of the morphological criteria using well-defined, well-characterized cases and find meaningful parameters that are quantitatively categorized. In previous reports we have introduced parameters centered on the nucleus area. This article will describe the parameters that reflect the shape and arrangement of the nuclei.
