✦ Synopsis

spectively, to differentiate false-negative frozen-section patients (microscopic lymph node disease) from true positive patients (unpublished data). Only at the extremes of PSA and grade can we predict lymph node metastases with greater efficiency than by frozen section and, for the majority of our patients, there is no relationship between PSA and biopsy grade, and size of the metastasis. Metastasis does not necessarily result in lymph node enlargement.

As prostate cancer is diagnosed "earlier," I anticipate that a greater proportion of metastases will be occult,' for the diagnosis of which current routine clinical laboratory tests and imaging are inadequate. The application of new diagnostic technology (such as polymerase chain reaction amplification" for the detection of currently occult cancer cells in the blood stream or tissues obtained with minimally or noninvasive techniques with imaging localization) is needed for the accurate and cost-effective staging and treatment of prostate cancer.
