Background: The pre-biopsy (bx) prostate-specific antigen (PSA) level, tumor volume/diameter, degree of extraprostatic extension (EPE), and extent of surgical margin positivity have been shown to be significant prognostic parameters of biochemical recurrence (BCR) after radical prostatectomy. The present study assessed the cut-off values of the pre-bx PSA level, maximum tumor diameter, radial and circumferential distances of EPE, and circumferential length of surgical margin (SM) positivity with regard to BCR.
Material And Methods: The study included 445 radical prostatectomy specimens, and the cut-off values of all parameters were determined using receiver operating characteristic curve analysis.
The presence of occlusion/near-occlusion of glomerular capillaries was recently added to the existing definition of glomerulitis (g). We retrospectively re-evaluated 135 renal allograft biopsies regarding g to ensure no antibody-damaged grafts were missed. Previous and revised g scores (pg and rg, respectively) were compared for clinicopathologic correlations.
