Purpose: The objective of this study is to evaluate the survival rate and influencing factors. Patients and Methods: We studied 104 patients who were diagnosed for squamous cell carcinoma of tongue and received curative treatment in oral oncology clinic of National Cancer Center from June 2001 to December 2009. Results: We found the following results. 1. The overall 5-year survival rate of tongue cancer was 67.0% and there was no significant statistical difference between male and female. 2. A lower survival rate was shown in patients under 40 years (42.2%) than over 40 years (75.5%)(P 44.1%)(P<0.05). 5. A higher survival rate was seen in patients of tongue cancer with higher differenciation grade (P<0.05). 6. It is well known that drinking and smoking have great influence on the survival rate of patients of squamous cell carcinoma of tongue. But these was no statistical significance. Conclusion: The overall 5-year survival rate of tongue cancer was 67.0% and it was mostly influenced by factors like age, pTNM stage, cervical lymph node metastasis, differentiation of cancer cell etc.
