The purpose of this epidemiologic study was to provide clinically useful information on the fundamentals for both the diagnosis and treatment planning of oral squamous cell carcinoma, which comprises 80~90% of all oral cancers. One hundred and forty two patients diagnosed with oral squamous cell carcinoma were selected from a total of 220 patients with oral malignancies. The patients’medical and follow-up records were reviewed and their survival was traced. The highest occurrence rate was observed in those aged between 60 and 69 years. The tongue was the most common primary site(31.7%) for oral squamous cell carcinoma. The survival rate was calculated using the Kaplan-Meier method. The overall five-year survival rate of oral squamous cell carcinoma patients was 66.90%. The 5-year survival rate according to stage was 85.82% for stage I, and 49.98% for stage IV. The five-year survival rate according to the originating site was 91.67% for the retromolar trigone, 75.30% for the tongue, and 62.41% for the maxillary gingiva. In terms of cell differentiation, the majority (58.5%) was the well-differentiated type, which had a 5-year survival rate of 70.62%.
