Objective: To probe into the influencing factors of the prognosis of the elderly patients with tongue squamous cell carcinomas.

Conclusion: Local control for the carcinomas is the key factor of influencing prognosis;the next comes radical neck node dissection;comprehensive treatment is better than simple one.
