[Significance of prostatic acid phosphatase, gamma-seminoprotein and prostatic specific antigen in the urine. First report: the measurement of PAP, gamma-Sm and PA in the urine of patients with prostatic diseases].
To study the significance of prostatic acid phosphatase (PAP), gamma-seminoprotein (gamma-Sm) and prostatic specific antigen (PA) in urine, we have determined the urinary levels of these proteins in women and infants, in patients without prostatic disease, in patients with benign prostatic hypertrophy, and in patients with prostatic adenocarcinoma. Women and infants were found to excrete little PAP (27.9 +/- 4.8 ng/mg) and undetectable levels of gamma-Sm except one case, and undetectable levels of PA in the urine. The excretion of PAP in patients with prostatic carcinoma who were either castrated, or treated with endocrine therapy was lower than the levels in women and infants, or the levels in patients without prostatic diseases, or the levels in patients with BPH. Urinary excretion levels of gamma-Sm and PA were undetectable in the patients with well-controlled prostatic carcinoma. The present study suggests that the determination of PAP, gamma-Sm and PA in the urine of patients with prostatic carcinoma may become a useful tool for monitoring of the primary locus of the carcinoma, but additional assays of urinary PAP, gamma-Sm and PA should be measured at regular intervals to be concluded.
