[Citrate and acid phosphatase in the ejaculate in prostatic carcinoma and adenoma].

The simultaneous determination of acid phosphatase and citrate concentration in the seminal fluid obtained from 16 patients with prostatic adenoma showed normal values, 6 patiients with prostatic carcinoma (cytologically and histologically verified) however extremely low values. The difference between persons with prostatic cancer and those with adenoma became particulary obvious with both experimental results evaluated in the way of a twodimensional diagram. This clear separation of both clusters by the simultaneouse estimation of both biochemical parameters may possible get useful diagnostic significance.
