Active Control of Prostatic Cancer With Criteria of Latence

Study Overview
=================
Brief Summary
-----------------
This study concern a prospective cohort pf patients with latent prostate cancer. We study the specific survival at 10 years of patients who accept an active control.Patients inclusion are realized in 2 stages: patient with inclusion criteria (PSA < 10 ng/ml, clinical stage T1c or T2a, Gleason < or = 6) are registered if they accept a second prostate biopsy in a 3 months delay after analyse of second biopsy in central laboratory and confirmation of latent prostate biopsy, patients are included if they accept active control Included patients will have 1 biopsy by years the first two years and then 1 biopsy each 2 years during 8 years. If progression of cancer happens during the 10 years control, active control will be stopped and patient will be treated by surgery and chemotherapy.

Detailed Description
-----------------
This study concern the active control during 10 years of patient with latent prostate cancer who accept not be treated immediately.
