Resumen
Upfront surgical resection with safe margins is a mainstay of treatment in oral cancers. The postoperative risk stratification of the resection margin is currently determined through surgical pathology according to a cut-off width of 5 mm. However, evidence to support the validity of this cut-off point of 5 mm is not strong, and was largely obtained from retrospective clinical studies. In this review, we summarize surgical concepts for oral cancer, postoperative risk stratification based on current guidelines and propose a dynamic cut-off value for postoperative risk stratification in oral cancer.
