This study from Paris, France looked retrospectively at 199 patients undergoing minimally invasive prostate surgery with high risk prostate cancer. They found that while positive margin did not correlate with increased BCR, pathological stage ≥T3 did.
The short followup of 23 months in this cohort makes it impossible to definitively conclude that BCR is not affected by positive margin rate. Another factor not considered in the analysis was the adjuvant use of ADT, which can certainly affect the study outcome.
