Abstract: Pathological staging and surgical margin status of radical prostatectomy specimens are next to grading the most important prognosticators for recurrence. A central review of pathological stage and surgical margin status was performed on a series of 552 radical prostatectomy specimens of patients, participating in the European Organisation for Research and Treatment of Cancer trial 22911. Inclusion criteria of the trial were pathological stage pT3 and/or positive surgical margin at local pathology. All specimens were totally embedded. Data of the central review were compared with those of local pathologists and related to clinical follow-up. Although a high concordance between review pathology and local pathologists existed for seminal vesicle invasion (94%, kappa=0.83), agreement was much less for extraprostatic extension (57.5%, kappa=0.33) and for surgical margin status (69.4%, kappa=0.45). Review pathology of surgical margin status was a stronger predictor of biochemical progression-free survival in univariate analysis [hazard ratio (HR)=2.16 and p=0.0002] than local pathology (HR=1.08 and p>0.1). The review pathology demonstrated a significant difference between those with and without extraprostatic extension (HR=1.83 and p=0.0017), while local pathology failed to do so (HR=1.05 and p>0.8). The observations suggest that review of pathological stage and surgical margin of radical prostatectomy strongly improves their prognostic impact in multi-institutional studies or trials.
