目的:探讨乳腺单纯癌临床诊断的量化标准。方法:对20例中期和20例晚期乳腺单纯癌癌细胞粗面内质网、游离核糖体、多核糖体的7个形态参数进行体视学分析,用逐步判别分析法剔选各参数值,建立判别函数。结果:Vvr2、Svr2、SR与Sr2之间有显著性差异（P<0.01）,回代判别正确率达到85.7％。结论:本研究建立的乳腺单纯癌临床诊断量化标准对鉴别诊断乳腺癌及判断其恶性程度和预后具有重要意义。
Objective: To investigate the quantitative criteria of clinical diagnosis of simple breast cancer. Methods: Seven morphological parameters of rough endoplasmic reticulum, free ribosomes and polysomes in 20 cases of metaphase and 20 cases of advanced breast carcinoma were analyzed stereoscopically. The values of parameters were determined by stepwise discriminant analysis. Establish discriminant function. Results: There was significant difference between Vvr2, Svr2, SR and Sr2 (P <0.01), and the accuracy of back analysis was 85.7%. Conclusion: The diagnostic criteria for the diagnosis of simple breast cancer established in this study is of great significance for the differential diagnosis of breast cancer and the determination of its malignancy and prognosis.
