Objective: Microscopic tumor at the inked surgical margin has an adverse effect on outcome in oral cancer. This study examines the impact of the width of the close surgical margin on survival.

Design: Pathology reports were reviewed for the status of the surgical resection margin in a historical cohort of 277 patients with oral cancer. Cox proportional hazard models were used to determine the independent effect of the surgical margin, in millimeters, on survival.
