Workgroup 2: Staging and reporting of prostate cancer--Sampling of the radical prostatectomy specimen

he following document represents recommendations pertinent T only to a pathologic TNM staging system.This summary is not intended to debate the prognostic importance of any of the morphologic parameters listed (volume, multicentricity, zonal origin, etc.). TNM STAGING SYSTEM T1 ClassificationThere is no pathologic correlate to Tla and Tlb cancer in the radical prostatectomy specimen.T l c classification translates to a final pathologic spectrum ranging from T2 to lymph node positive cancer.Better prediction of the final pathology stage for clinical classification Tlc can be achieved by prostate specific antigen and Gleason score on biopsy. T2 ClassificationsAre pathologic T2 subclassifications based on lobe concept appropriate?No. If the tumor is confined to the gland, there are not data to suggest that bilaterality is important.Additionally, there is no anatomic definition of "lobes" in the radical prostatectomy.
