    Abstract:
    OBJECTIVES: To estimate the frequency and characteristics of prostatic lesions discovered incidentally in radical cystoprostatectomy specimens and to determine whether any factors would allow for the detection of prostate cancer preoperatively. METHODS: A total of 100 radical cystoprostatectomy specimens with orthotopic bladder reconstruction were performed for malignant bladder disease between 1990 and 2000. The mean patient age at surgery was 62 +/- 8 years (range 32 to 75). Digital rectal examination and prostate-specific antigen (PSA) assay were done routinely before surgery. During the 10-year study period, the same pathologist examined the prostatic tissues from radical cystoprostatectomy specimens using McNeal's technique on fine slices every 2.5 mm. RESULTS: The overall incidence of prostate cancer discovered incidentally in radical cystoprostatectomy specimens was 51%, of which 29% were microcancers (volume less than 0.5 cm3) and 22% were significantly larger (volume 0.5 cm3 or more). The mean Gleason score was 6. Of the tumors, 24% could be considered "clinically nonsignificant" (less than 0.5 cm3 and Gleason score less than 7). The mean preoperative PSA level was 4.13 +/- 1.36 ng/mL. Of 66 patients with a PSA level of less than 4 ng/mL (mean PSA 1.5 +/- 0.8) and a normal digital rectal examination before surgery, 50% had prostate cancer, of which 69% were microcancers. CONCLUSIONS: The prevalence of prostate cancer (51%) in our series is among the highest in published reports. Furthermore, our results stress that currently no factors are available to enable the detection of "clinically significant" prostate cancer preoperatively.
