1878例涎腺肿瘤WHO组织病理学新分类的统计分析

Statistical analysis of 1878 salivary gland tumours according to new WHO classification

目的 根据 Ｗ Ｈ Ｏ１９９０ 年涎腺肿瘤组织病理学新分类标准对１８７８ 例涎腺肿瘤及肿瘤样疾病进行重新分类，并重点对涎腺上皮性肿瘤的临床发病情况进行统计分析。方法 统计描述。结果 １８７８ 例涎腺肿瘤以涎腺上皮性肿瘤为主，为１４３１ 例，占７６ ．２０ ％ ，其中腺瘤发病居首位，其次是涎腺癌，涎腺肿瘤样疾病居第三位；多形性腺瘤是涎腺肿瘤中最常见者，恶性多形性腺瘤为最常见的涎腺癌，特别注意了腺癌亚分类中的几种少见类型。涎腺肿瘤的性别分布除腺淋巴瘤外一般无明显差异；涎腺腺瘤的发病年龄早于涎腺癌，涎腺腺瘤多发于大涎腺，涎腺癌以小涎腺稍多见，腮腺是涎腺肿瘤最常见的发病部位。结论 涎腺肿瘤 Ｗ Ｈ Ｏ

Objective To classify 1878 of salivary gland tumours and tumour-like lesions,especially statistically analyse clinical features of epithelial tumours according to new WHO histological classification in 1990.Methods Statistical description.Results Epithelial tumours were 1431 cases,constituting 76.2 percent of all cases.Of all salivary gland tumours,the incidence of adenomas ranked the first,carcinomas the second,tumour-like lesions the third;pleomorphic adenoma was the most commonly seen type among all salivary gland tumours and tumour-like lesions,malignant pleomorphic adenoma was the most frequently encountered lesion in all salivary gland carcinomas.Attention should be paid.several rare types of subclassification of adenocarcinomas.In general,the majority of salivary gland tumours,except adenolymphoma,had no sex predilection.Adenomas occurred earlier than the adenocarcinomas.Adenomas mostly occurred in the majou salivary glands,whereas adenocarcinomas exhibited a slightly higher occurencce rate in minor salivary gland.The parotid gland was the most common site of salivary gland tumours.Conclusion To the clinicians and pathologists,the new WHO histological typing of salivary gland tumours plays an important role in further understanding the clinical and histologic features of salivary gland tumors.
