Summary
The prognostic value of surgical resection margins in predictingrecurrence of desmoid-type fibromatosis remains inconclusive, and appropriate resection margins are not defined. We analyzed whether specific factors related to margin status, including the adequacy of pathologic assessment, affect the prognostic impact of surgical resection margins in a retrospective cohort study. Surgical resection margin status, as currently evaluated and reported, fails to predict recurrence-free survival for desmoid tumors. Instead, positive or close (<1 mm) resection margins are predictive of disease recurrence. In addition, multiple targeted sections are necessary for accurate assessment of surgical resection margins of desmoid-type fibromatosis.
