Task: Answer Verification
Input (English): Question: Does site of positive surgical margins influence biochemical recurrence after radical prostatectomy?
Answer: About half of the men with PSMs in the RP surgical specimen in our prospective series did not develop BCR. The risk of BCR was dependent on the site and not the number of PSMs. Adjuvant therapy should be considered in cases with anterior and basilar PSMs due to the very high risk of BCR.
Output (English): yes
