Head and neck squamous cell carcinoma mainly tends to occur in people aged between 50 and 70. However, the incidence of head and neck cancer among aged and young patients has increased in recent years. In this report, we compared the clinical findings and therapeutic courses between both groups. The incidence of patients with tongue cancer was mostly in the young group occupying 48.2%, while gingival cancer of lower jaw was mostly in the aged group. With regard to the advanced cancer cases, aged patients outnumbered young patients. We treated all young patients by radical method, while we have chose palliative therapy for 30.8% of the aged patients by reason of their systemic complications or advanced tumors. Systemic complication patients occupied 69.2% in the aged group, which was three times higher than that of the young group (22.2%). The three-year survival rate was 84.0% in the young patients and 51.3% in the aged patients. The young patients below 39 years old showed higher distant metastases rates after primary therapy. It may be important to know physical features and the nature of tumors in young and aged patients to improve prognosis. We planned radical therapy for the aged patients as far as systemic conditions permitted.
