口腔内癌肿396例临床病理分析

Clinical and Pathological Analysis of 396 Cases on Oral Cancer

本文通过我院收集的近７年口腔内癌肿３９６例与日本癌学会１９９０年发表的３５０例口腔癌材料对比分析，可以明确看出来源于口腔粘膜被覆上皮的癌瘤占９６％以上，其中以鳞状细胞癌为绝大多数．在来自小涎腺导管上皮的癌瘤中以腺样囊性癌和粘液表皮样癌居多．口腔癌的好发部位以舌占首位，日本的材料中显得更为突出，占５９．４％．在其他部位上，两国材料有较大差异，我们的资料中牙龈癌占第二位，口底癌相对少见，与西方某些国家的统计相近，日本资料中口底癌的发病仅次于舌癌．其发病年龄段均以５０～６９岁间为高发，平均年龄分别为５４．９岁和５９．２岁．在性别方面，资料均显示以男性为多，且所占比例也较接近．本组３９６例中，非上皮源性恶性肿瘤共有８例约占２％，其中口腔粘膜恶性黑色素瘤占半数．

By comparing of the oral cancer samples collected by our hospital in the recent 7 years with those published by the Clinical and pathological analysis of Japan,it can be found clearly that the cancer arising from covering epithelium of oral mucous membrane accounted for more than 96%.Most of them are squamous cell carcinoma.In the cancer arising from small salivary gland duct epithelium Adenoid cystic carcinoma and mucoepidermoid carcinoma were most common.Tongue is the site that oral cancer occurs mostly,it is more prominent in the samples of Japan.and Japan.The prevalence is about 59.4%.At other sites,there is a significant difference between the samples of China and Japan. In our samples,gingiva carcinoma runs the second and oral bottom carcinoma is rare relatively,this result is similar with that of some western countries,however,in the data of Japan,the prevalence of oral bottom carcinoma is second to tongue carcinoma. Frequently suffuring age in the 2 countries are both between 50 to 69 years old,the average is 59. 2. about the sex,male is more than female in the cases of both China and Japan and the proportion are similar too.In the 396 cases of our hospital,there are 8 cases of nonepithelial malignant tumor, it accounts for 2% one-half of them appears as malignant melanoma of oral mucous membrane.
