Do location , extent and number of positive surgical margins improve accuracy of predicting prostate cancer recurrence after radical prostatectomy?
The number and extent of positive surgical margin significantly influence the risk of biochemical recurrence after radical prostatectomy. However, the empirical prognostic usefulness of subclassifications of positive surgical margins is limited.
A prior benign prostate biopsy may be independently associated with more favorable surgical and biochemical outcomes after prostatectomy. Additional studies are needed to confirm these findings.
