Measurement of cytological features and DNA content was made on epithelial cells from 40 cases of gastric dysplasia and carcinoma graded by subjective scoring with IBAS image analysis system. The measurements were statistically compared with the subjective scores by using discriminant analysis. The result was noticed to provide significant discrimination between the different groups; and nuclear area, nuclear perimeter, nuclear form factor, percentage of 2C cells and percentage of aneuploid cells were all proved to be discriminating variables. Application of classification equation derived from discriminant analysis showed good results for the prediction of different individual cases.
使用IBAS图像分析系统,对40例经主观评分分级的胃发育异常和癌的上皮细胞进行细胞学特征和DNA含量的测量。通过判别分析将测量结果与主观评分进行统计学比较。结果显示不同组之间有显著差异;核面积、核周长、核形态因子、2C细胞百分比和非整倍体细胞百分比均被证明是判别变量。应用判别分析得出的分类方程对不同个体病例的预测效果良好。
