 note = {To evaluate the prognostic factors for treatment outcome of 135 patients with oral squamous cell carcinomas treated between 1985 and 1998 were analyzed. The 5-year survival rate for entire population was 69%. The value for the tongue (N=53) was 76%, which was followed by 70% of mandibular gingiva (N=29), 65% of the floor of the mouth (N=21), 61% of the buccal mucosa (N=12), and 54% of the maxillary gingiva (N=20). In terms of T and N classifications, the 5-year survival rates for T1 (N=28), T2 (N=48), T3 (N=7), and T4 (N=52) were 96%, 78%, 57% and 47%, and N0 (N=72), N1 (N=34), N2 (N=27) were 79%, 64% and 53%, respectively. The corresponding values for StageⅠ(N=27), StageⅡ (N＝27), StageⅢ (N=20), and Stage Ⅳ (N=61) were 96%, 75%, 75% and 52%, respectively. The value also decreases from 84% to 48% with the increase of grade of invasion. Surgically treated patients (N=90) showed the highest 5-Year survival rate (82%). The outcome was poor in patients with advanced tumor and tumors showing diffuse invasion pattern., 最近14年間(1985年～1998年)における口腔扁平上皮癌135症例の治療成績について検討を行った｡原発部位別、T分類別、N分類別、臨床病期別および病理組織学的浸潤様式別の5年累積生存率を算出し比較した｡全135症例の5年生存率は69%であった｡発生部位別では舌が(N＝53)76%、下顎歯肉(N=29)が70%、口底(N＝21)が65%、頬粘膜(N=12)が61%、上顎歯肉(N=20)が54%であった｡T分類別ではTl(N＝28)は96%、T2(N＝48)は78%、T3(N＝7)は57%、T4(N＝52)は47%であり、N分類別ではN０(N＝72)が79%、N１(N＝34)が64%、N2(N=27)が53%であった｡臨床病期別では、StageI (N＝27)は96%、StageⅡ (N=27)は75%、StageⅢ (N＝20)は75%、StageⅣ (N=61)は52%であった｡病理組織学的浸潤様式別では、GradeI (N＝58)が84%、GradeⅡ (N＝51）が61%、GradeⅢ (N＝20)が48%であった｡以上の結果から進行症例および、び慢性の浸潤株式を示す症例の治療成績が低かった｡},
