为了解乳腺癌与其它良性乳腺病变在分泌粘液性状上是否有诊断意义上的差异，本文运用ＰＡＳ、ＡＢ、ＨＩＤ３种粘液染色方法分别观察了乳腺的纤维腺瘤１１例，结构不良１１例，大导管乳头状瘤１０例，浸润性导管癌１２例及粘液癌１１例，共５５例进行粘液特性分析。结果表明良性病变３组唾液酸粘液的阳性率明显低于恶性病变２组；ＡＢ阳性率Ｐ＜０．０５，有显著性差异，提示乳腺肿瘤分泌唾液酸粘液增多与乳腺癌生长有关，且ＡＢ染色可做为乳腺癌诊断的辅助手段。
In order to understand whether the breast cancer and other benign breast lesions have diagnostic significance in the secretion of mucus, PAS, AB, HID three kinds of mucin staining method were used to observe 11 cases of fibroadenoma of the breast, 11 cases of poor structure, and large 10 cases of ductal papilloma, 12 cases of invasive ductal carcinoma and 11 cases of mucinous carcinoma, a total of 55 cases of mucus characteristics. The results showed that the positive rate of sialic acid mucus in the three groups of benign lesions was significantly lower than that in the malignant lesions group 2. The positive rate of AB was P<0.05, with significant difference, suggesting that the increased secretion of sialic acid mucus in breast tumors is related to the growth of breast cancer, and AB Staining can be used as an aid in the diagnosis of breast cancer.
