[925] Do the Tables and Nomograms Commonly Used by Clinicians To
Predict Pathological Stage in Men with Biopsy Gleason Score (GS)
8-10 Adenocarcinoma of the Prostate Match What Is Seen at
Radical Prostatectomy (RP)?  Brian Robinson, Nilda Diana
Gonzalez Roibon, Bruce Trock, Jonathan Epstein. The Johns
Hopkins Hospital, Baltimore  Background: The Partin Tables and
the Kattan Nomogram are the two most commonly used tools to
predict the pathological stage at RP based on preoperative
clinical findings and biopsy pathology. These tools use
mathematical equations (logistic regression) which are primarily
based on the majority of men with prostate cancer (ie. biopsy GS
≤7) to predict the outcome for all men, including those with
higher grade cancer on biopsy. It is unknown how accurate these
predictions are which can have significant implications for
deciding therapy. Design: 411 men with GS 8-10 prostate cancer
on biopsy (2004-2010) who under RP at our institution were
studied. All RPs were serially sectioned and s
