Overview

Evaluates whether positive surgical margin length predicts recurrence in patients post partial nephrectomy, suggesting presence alone is key.

Key Points

  • To determine if the length of positive surgical margins affects the risk of tumor recurrence after partial nephrectomy.
  • Data analysis from patients who underwent partial nephrectomy at six centers
  • Comparison between positive surgical margin and negative surgical margin groups
  • Statistical analysis using SPSS software with a significance threshold of p<0.001
  • Pathologic reevaluation and measurement of surgical margins in micrometers
  • Local recurrence occurred in 16.98% of patients with positive surgical margins (PSM) and 4.24% in the negative surgical margin (NSM) group (p<0.001)
  • Patients with PSM were at fourfold increased risk for recurrence
  • No significant correlation was found between positive margin length and local recurrence (p=0.044)
  • Presence of a PSM is a significant risk factor for recurrence, suggesting extent is less critical.
