Cytologic examination of post prostatic massage specimens as an aid in diagnosis of carcinoma of the prostate.

The results of cytologic examination fo post-massage prostatic secretion from symptomatic and asymptomatic subjects were evaluated by comparison with available tissue diagnosis. Specimens studied consisted of post-prostatic massage secretion and urine. The latter specimen gave much superior results. Although possibility of the cytologic diagnosis in prostatic carcinoma cases was limited, it proved to be reliable. Presently available short follow-up data indicate that this technique may play a role only as a diagnostic aid, however, its real value in prostatic cancer detection, could be only evaluated by long term follow-up of the "high risk" group.
