1808例老年口腔颌面部肿瘤构成比分析

The Composition of Oral-maxillofacial Tumors in 1808 Elderly Cases

[目的]探讨目前我国老年人口腔颌面肿瘤的构成比及发展趋势。[方法]收集本院20世纪90年代以来口腔颌面外科老年住院肿瘤患者1808例 ,并针对发病年龄、性别、部位与不同病种构成比的相关性进行统计分析。[结果]1990年1月～1999年6月 ,老年肿瘤患者1808例 ,占患者总数的11.73% ,其中恶性肿瘤1235例 ,占68.31% ;良性肿瘤573例 ,占31.69% ;恶性肿瘤中鳞癌占78.14% ,涎腺恶性肿瘤中腺样囊性癌占28.4% ;良性肿瘤中腺源性肿瘤占54.80% ,其中多形性腺瘤占34% ,腺淋巴瘤占28% ,发生于腮腺的占50.61%。[结论]口腔颌面外科住院肿瘤患者总数呈上升趋势 ,60岁～69岁年龄段老年患者占主要比例 ,女性有增加趋势 ;腮腺为高发部位 ,提示老年人腮腺区应作为普查项目 ;恶性肿瘤中 ,鳞癌居首位 ;腺源性良性肿瘤最多见 ,其中以多形性腺瘤居首位 ,其次为腺淋巴瘤 ,两者发病率的差距缩小。

PurposeTo investigate the compostion of oral and maxillofacial tumors in the aged patients.Eighteen hundred and eight cases inpatients with oral and maxillofacial tumors in the period of 1990s were collected and analyzed including age,sex,site and pathology.From Jan.1990 to Jun.1999,the aged patients of tumors were 1808 cases,among them,the malignant tumors were 1235 cases(68.31%);Benign tumors 573 cases(31.69%).Squamous cell carcinoma (SCC)accounted for 78.14%;Adenoidcystic carcinoma (ACC),28.4%;Pleomorphic adenoma,34%;and lymphadenoma,28%.[Conclusions]Occurrence of oral and maxillofacial tumors among the aged people is increasing especially in 60～69 age old.Parotid region is the most common site of occurrence,mass screening should pay more attention to this area. SCC is the most common type in malignances,while ACC ranks the first in malignant salivary glands;The pleomorphic adenoma ranks the first in the benign salivary gland tumors (34%);and the lymphadenoma ranks the second (28%),indicating small difference of the incidence between the two types of tumors.
