This multi-practice community based study confirms the inadequacy of sextant biopsies and emphasizes the need for extended peripheral zone sampling of the lateral aspect of the prostate. Generally increasing patient age and PSA were associated with larger, higher grade tumors. Extended biopsy schemes minimize PSA and age related detection rates.

Information from pathological study of sextant prostate biopsies, preoperative PSA blood test and a new image analysis variable termed quantitative nuclear grade can be combined to create a multivariate algorithm that can predict more accurately nonorgan confined prostate cancer compared to previously reported methods.

The components that comprise the most accurate decision support tools for clinical staging represent an appropriate staging evaluation for the newly diagnosed prostate cancer patient in 1997. Limited use of radiographic imaging and seminal vesicle biopsy may be indicated in select patients to detect bone metastases, and plan pelvic lymphadenectomy and surgical therapy.
