[Optimization biomarkers in the surveillance of non muscle invasive bladder cancer.].

Introduction: Bladder cancer is thefifth most common tumor in the world. Moreover, it isone of the most expensive due to its high recurrencerate. Urinary biomarkers for surveillance of non muscleinvasive bladder cancer is a promising and growingfield due to the invasiveness of the actual methods, basedon cystoscopy and cytology.

Is there a relationship between prostate volume and Gleason score?

Objectives: To review the relationship between the Gleason grade and prostate volume in biopsy and radical prostatectomy (RP) specimens, and thus assess the hypothesis that smaller prostates have a greater incidence of high-grade tumours.

Patients And Methods: We selected 390 patients who had RP at our institution, with a prostate-specific antigen (PSA) level of < 10 ng/mL and who had not had hormonal therapy. We retrospectively reviewed the data for transrectal ultrasonography (TRUS)-guided prostate biopsies from these patients and the RP specimens.
