Sixty-five patients with oral cancer, treated at Mie University Hospital for 7 years between 1992 and 1998, were reviewed. The average age was 63.7-years-old. Primary site of oral cancer was the tongue in 34, oral floor in 15, buccal mucosa in 8, gingiva in 5, and the hard palate in 3. The 5-year survival rate analyzed by Kaplan-Meier method was 100％, 75.0％, 61.5％, 91.7％, 21.9％ and 0％, respectively for stage 0, I, II, III, IVA and IVC. The high survival rate in stage III indicates the effectiveness of therapy by superselective intraarterial chemotherapy combined with radiation. The 5-year survival rate by the site was 59.7％, 53.0％, 62.5％, 50.0％, and 100％, respectively for tongue, oral floor, buccal mucosa, gingiva, and hard palate.
Key words : oral cancer, survival rate, superselective intraarterial chemotherapy
