Abstract
Previous reports have shown binding of peanut agglutinin (PNA) by immunoperoxidase techniques in normal, benign proliferative, and malignant breast epithelia. Correlation of binding with maturity, secretory activity, hormonal milieu, and tissue hormone receptor content has been described. To investigate the relationship between PNA staining by the avidin-biotin complex technique and estrogen receptor (ER) content, 79 breast tumors of different types and known tissue ER content were studied. Thirty-eight of 50 ER-positive cases were PNA-positive. Twenty of 29 ER-negative cases were PNA-positive. Statistical analysis shows the two factors to be independent (0.5 < P < 0.9). The literature on blood group antigens in breast carcinoma and histochemical applications of PNA is reviewed.This publication has 19 references indexed in Scilit:
