[Cytology in the diagnosis of prostatic cancer (author's transl)]

We are reporting our 20 years experience in the cytological diagnostic study of prostatic cancer. We studied at the same time, urinary cytology and prostatic histology in 217 patients. There were 50% false positive results with urinary cytology. Franzen aspiration enabled us to diagnose 81% of all prostatic cancers. These two methods are possible on an out-patient basis and enable us to determine high risk patients and to diagnose prostatic cancer earlier.
