To establish whether histopathologic variables other than the pathologist's statement of complete excision predict recurrence of squamous cell carcinoma at the primary site and therefore indicate local postoperative radiotherapy. ⋯ When excision of a small squamous cell carcinoma of the mobile tongue or the floor of the mouth is histologically complete, other histopathologic variables are irrelevant in predicting recurrence at the primary site, and local radiotherapy is not indicated, considering the morbidity and high number of second and third primary tumors to be expected that will require future new treatment.
