In order to clarify a methodology for and the problems of treating the longer aged patients with oral cancer, sixty-six patients with primary oral squamous cell carcinoma (SCC), who were over 75 years old, were clinically investigated and compared to the patients under 75 years old. Patients over 75 years old accounted for 30.4% of the total 217 patients with primary oral SCC, who were treated in our hospital from January 1999 to July 2009. In these longer aged patients, the primary site where oral SCC most frequently developed was gingiva, although the tongue is the most popular site where oral SCC occurs in general. Fifty-four percent of the patients were in Stage III and IV. The 5-year cause-specific survival rate was 84.0% in the patients over 75 years old who were undergoing radical treatments for tumors. These results suggest that radical incision treatments with reconstructive procedures can improve the long-term survival rate even in patients aged over 75 years if their general condition is tolerant of surgical stress.
