Histochemical study of R1881-binding protein, prostatic acid phosphatase, prostate-specific antigen, and r-seminoprotein in prostatic cancer.
A histochemical study on R1881-binding protein, prostatic acid phosphatase (PAP), prostate-specific antigen (PA) and r-seminoprotein was conducted. These parameters and histologic grades were compared to each other and with the responsiveness to endocrine therapy. A good correlation was found between histologic grade and presence or absence of R1881-binding protein in the tissue. Presence or absence of R1881-binding protein as well as histologic grade correlated well with responsiveness to endocrine therapy. Positive staining patterns of PAP, PA, and r-seminoprotein in the tissues were similar to each other, particularly between PA and r-seminoprotein. However, no correlation was found between the histologic grade and ratios of PAP, PA or r-seminoprotein-positive cells. Nor was any correlation seen between the ratio of these marker-positive cells and responsiveness to endocrine therapy.
