Abstract

<p>We investigated 364 patients diagnosed histologically as having malignant tumors at the First Department of Oral and Maxillofacial Surgery, Osaka Dental University Hospital, be­ tween January 2005 and December 2014. There ware 321 primary cases, 24 recurrent and me­ tastatic cases and 19 multiple oral cancers. Among the primary tumor patients there were 185 males and 136 females for a male to female ratio of 1.4 : 1. The average age was 65 years. His­ tologically, there were 265 cases (82.6%) of squamous cell carcinoma (SCC), 14 (4.4%) of ver­ rucous carcinoma, and 9 (2.8%) of mucoepidermoid carcinoma. The tongue (40.8%) was the most common site of SCC, followed by the gingiva (37.7%), buccal mucosa (9.1%), and oral floor (8.7%). The peak age was the sixth decade for SCC, while the tongue was the most com­ mon site for those under 60 years of age. The gingiva was the most common site for those 60 years of age. According to the clinical stage, 32 cases were in stage 0, 52 in stageⅠ, 85 in stage Ⅱ,34instageⅢand 56 in stage Ⅳ. There were 10 cases of multiple carcinoma compli­ cated with SCC variants.
