[Early diagnosis of prostate cancer in patients with prostate symptoms by DRE, PSA, TRU and DPSA].

Abstract Presentation of our experience in the early diagnosis of prostate cancer in patients with signs and symptoms of prostatism. Over a one year period (96-97), 316 patients underwent biopsy based on clearly defined criteria according to the diagnostic algorithm used in our centre: suspicious DRE and/or PSA > or = 10 ng/mL, and in patients with PSA between 4 and 10 ng/mL in the presence of suspicious TRU or when DPSA was > or = 0.15. The ratio of the 136 (43%) prostate cancer diagnosed relative to biopsy +/- was 1:1.32. It is concluded that early diagnosis in a selected population is useful and shows good diagnostic yield. The diagnostic algorithm used is more than acceptable with 43% positive biopsies and a good ratio between biopsy +/-. With a cutoff of 0.15 DPSA is a good method to improve PSA significance in patients in the difficult PSA range of 4 to 10 ng/mL.
