5201例口腔合颌页面肿瘤统计分析

 目的　通过分析广西医科大学1970～1989年20年间口腔颌面部肿瘤的病理检查资料(来自广西各地区)，进一步了解口腔颌面部肿瘤的发病状况。方法　分析经病理检查首次确诊原发于口腔颌面部肿瘤5201例，按其性质、组织类型、性别、就诊年龄与部位进行统计分析，并与首次确诊的全身原发肿瘤进行比较。结果　口腔颌面部肿瘤占全身肿瘤的7.67%，占头颈肿瘤19.39%，恶性肿瘤略高于良性，恶性肿瘤男女之比1.68∶1，良性肿瘤高发年龄组为21～30岁，恶性肿瘤高发年龄组为51～60岁，恶性肿瘤中以癌为最多(82.07%)，而癌中以鳞状细胞癌最多，好发于舌部。结论　我校病理检查的口腔颌面部肿瘤各构成比，除恶性肿瘤高于良性外，基本上与国内外各地区的报告相似。

Statistical Analysis of 5201 Patients with Neoplasm in Oral-maxillofacial Region

Objective To analyze the clinicopathologic date of oral-maxillofacial neoplasme between 1970 and 1989 in Guangxi Medical University (all patients came from different places in Guangxi),and to investigate the incidence of oral-maxillofacial neoplasms in this area.Methods Analyze 5201 primary oral-maxillofcial neoplasms proved by pathohistology according to their clinicopathologic feature,histological type,sex,age and primary site with comparison to all new pathologically cnfirmed primary neoplasms.Results The neoplasms in this region constitute 7.67% of those in all sites and 19.39% of those in head and neck.The incidence of oral-maxillofacial cancer is slightly higher than that of benign oral-maxillofacial neoplasms and men are more frequently affected by cancer than women at a ratio of 1.68∶1.Most benign cases occur in patients between 21 and 30 years of age while cancer mostly occur in patients between 51 and 60 year of age.The commonest cancer in oral-maxillofacoal region is carcinoma (82.07%)，most of them are squamous cell carcinoma and the tongue exceed all other sites.Conclusion The results of proportions of oral-maxillofacial neoplasms pathologically confirmed in our university are similar to the previous reports except that the proportion of the malignant is higher than that of the benign.
