[Frequency of latent prostate cancer in patients with minute adenocarcinoma in a multi-focal biopsy].

Minute adenocarcinoma in a multi-focal biopsy (no less than 12 posts) on the prostate was detected in 12.62% of 507 cases of adenocarcinoma. Radical retropubic prostatectomy was carried out in 12 out of 64 (18.75%) patients with minute adenocarcinoma in a multi-focal biopsy. Latent prostate cancer was detected in 5 out of 12 surgical patients (42+28%: p=0.95). Out of 64 cases of minute adenocarcinoma in a biopsy, the expected number of latent prostate cancers was 27. Our data may be used in search for and investigation of clinico-morphologica criteria of detecting latent prostate cancer prior to therapy.
