Lectin binding to prostatic adenocarcinoma.
The binding of different lectins (concanavalin A [Con A], triticum vulgaris [WGA], glycine maximum [SBA], dolichos bilflorus [DBA], ulex europaeus [UEA I], arachis hypogaea [PNA], and ricinus communis [RCA I]) to cells of normal prostate glands, hyperplastic glands and adenocarcinoma was studied. The Con A, WGA, DBA, PNA and RCA I bound to both normal and hyperplastic glands. The binding in the malignant glands differed from that of the benign conditions. The SBA, which was not bound by benign cells, was bound to the malignant glandular cells. Also, UEA I was bound to a part of the carcinoma cells. In addition, the binding pattern of Con A and WGA in the cells differed between the malignant and benign conditions. Based on the results of this study, it is suggested that lectin histochemical study might be useful in routine pathologic examination to detect malignant cells in cases which are doubtful with regard to malignancy by routine methods.
