Advances in the assessment of clinically localized prostate cancer.
OBJECTIVE
We review the advances in pathology, biology, and radiology which could improve the detection of extracapsular prostate cancer preoperatively.


METHODS
The experiences of others are compared to ours to give a topical overview of advances in the assessment of clinically localized prostate cancer.


RESULTS
Despite new technologies, such as colour Doppler and endorectal magnetic resonance imaging, radiology does not enhance the ability to detect small invasion through the prostatic capsule. Biopsy features are one of the new fields of investigation. The number of positive sextant biopsies and the analysis of periprostatic spaces on biopsies appear to be major prognosis factors. In our experience, capsular perforation on biopsy is very powerful with respect to the proportion of positive biopsies ( > 66.7%) and serum PSA ( > 25 ng/ml, polyclonal assay) to predict biological progression after radical prostatectomy. The utility of the proportion of invaded tissue on biopsy is still debated.


CONCLUSIONS
Despite technical improvements, the staging of clinically confined prostate cancer is still a major issue. The best hope comes from the study of biopsy features in addition to PSA.
