Objective The purpose of this study was to examine which factors are associated with inadequate surgical margins and to assess the postoperative consequences. Study Design A retrospective cohort of 110 patients with oral squamous cell carcinoma treated with surgery during a 2-year period was examined. Clinical, histopathologic, and operative variables were related to the surgical margin status. Furthermore postoperative treatment data were compared with margin status. Results Univariate statistically significant associations were found between the tumor site in the floor of mouth, more advanced T-stage, increasing tumor thickness, and inadequate margins. Of the patients with involved margins, 87% were treated with postoperative radiotherapy or re-resection, but among patients with close margins, only 35% received either radiotherapy or re-resection. Conclusions Clinical and histopathologic factors were associated with the inadequate margin. Postoperative treatment for patients with close margins is controversial, and more studies are needed to define clear guidelines.
