title: Histochemistry of steroid receptors in prostatic diseases.
abstract: Tissue obtained from 55 men with prostatic disease was assayed for estrogen and androgen receptors by a newly developed histochemical technique. The material studied consisted of 45 specimens of benign nodular prostatic hyperplasia and 10 specimens of prostatic adenocarcinoma. The results obtained were compared to those of parallel biochemical assays in 17 cases and successfully correlated in 85 percent. The new procedure is rapid, inexpensive and accurate, allowing for the detection of receptor in cytoplasm and/or nucleus and evaluation of receptor heterogeneity. The histochemical method may offer an alternate to biochemical assay of prostatic tissue as contamination with steroid binding globulins does not appear to be a problem at this time.
