Grading Prostate Cancer
The continued relevance of the “old saw” quoted above was dramatically underscored recently at the Prouts Neck 1986 multidisciplinary meeting on the management of prostate cancer. During the meeting it became apparent that the ability to evaluate therapeutic modalities is seriously limited when differing histopathologic grading systems are used. Specifically, meaningful comparisons are severely compromised or negated if patient groups have been stratified differently. Clearly some common grading reference system is urgently needed in the published literature if clinical studies are to be compared.
