Complete surgical excision with radical neck dissection and postoperative radiotherapy is the preferred treatment. Recurrences are common and metastases to regional lymph nodes and distant sites occur in up to 70% cases. The prognosis depends upon the relative proportions of the in-situ and invasive components and their histologic grade. The high-grade invasive tumors have the worst prognosis and a mortality rate of around 70%. Low-grade tumors have the best prognosis.
