title: [Clinical studies of gamma-seminoprotein in prostatic disease. I. Clinical evaluation of serum gamma-seminoprotein].
abstract: Serum gamma-seminoprotein (gamma-Sm) in patients with prostatic disease was determined by enzyme immunoassay. A total of 136 patients including 13 untreated and 40 treated patients with prostatic cancer, 45 patients with benign prostatic hyperplasia (BPH) and 38 patients with other urological diseases were analyzed. The mean +/- SD of serum gamma-Sm in the 13 patients with untreated prostatic cancer and the 45 patients with BPH was 31.7 +/- 46.1 and 3.7 +/- 6.6 ng/ml, respectively, there being a statistically significant difference between the two groups. All patients with untreated stage A or B prostatic cancer had a serum gamma-Sm of less than 4 ng/ml (cut off value). The mean level of serum gamma-Sm was 5.1 +/- 1.9 ng/ml for all patients with untreated stage C prostatic cancer; 66% of them had a value above the cut off value. However, it was 55.9 +/- 52.6 ng/ml in all patients with untreated stage D prostatic cancer; 87.5% of them had a value above the cut-off value. These results suggest that gamma-Sm may be a useful tumor marker in the management of patients with prostatic cancer.
