  • Title: Tissue binding of lectins in disorders of the breast.
    Author: Franklin WA.
    Journal: Cancer; 1983 Jan 15; 51(2):295-300. PubMed ID: 6295598.
    Abstract:
    Twenty breast lesions including seven scirrhous ductal carcinomas, one infiltrating lobular carcinoma, one colloid carcinoma, four fibroadenomas, and seven cases of fibrocystic disease were analyzed by fluorescence microscopy for the presence and distribution of lectin-binding carbohydrates. Paraffin-embedded tissue sections were tested with wheat germ agglutinin (WGA), Ricin communis agglutinin I (RCA I), peanut agglutinin (PNA), Soybean agglutinin (SBA), Dolichos biflorus agglutinin (DBA), Ulex europaeus agglutinin I (UEA I), and concanavalin A (Con A). Brightest and most consistent staining regardless of the nature of the breast lesion was obtained with WGA followed in approximate order of staining intensity by RCA, PNA, SBA/DBA and Con A. UEA I stained many of the benign breast lesions but no malignant lesions. Lectin binding carbohydrate in benign lesions was localized mainly along the apices of mammary epithelial cells but there was considerable variation in staining patterns among malignant tumors. The fluorescence microscopic arrangement of lectin binding carbohydrate appears distinct for each malignant neoplasm of breast but is more consistent in benign conditions.
