目的:了解青海地区涎腺上皮性肿瘤发病情况、组织学类型、构成特点。方法:分析本院1990年1月—2014年12月间颌面外科切除并经病理确诊的涎腺上皮性肿瘤的相关资料。结果:涎腺上皮性肿瘤360例,55.3%发生在腮腺,其中良性肿瘤296例(82.2%),恶性肿瘤64例(17.8%);男女发病之比0.7;1,良性涎腺上皮肿瘤发病女性高于男性(170/126),恶性涎腺上皮肿瘤发病男性高于女性(36/28);良性涎腺肿瘤30岁后进入高发年龄段,恶性涎腺上皮肿瘤50岁以上发病者多见。良性涎腺上皮肿瘤排于前二位为多形性腺瘤和Warthin瘤,而恶性肿瘤排于前二位的是腺泡细胞癌和腺样囊性癌。结论:涎腺上皮性肿瘤发病呈上升趋势,腮腺是涎腺上皮性肿瘤好发部位,多形性腺瘤是涎腺最常见的良性上皮性肿瘤,涎腺上皮性恶性肿瘤发病较少,腺泡细胞癌相对比其他恶性肿瘤较多见。
Objective: To understand the incidence of salivary gland epithelial tumors in Qinghai Province, histological types, compositional characteristics. Methods: The data of salivary gland epithelial tumors excised and pathologically diagnosed in our hospital from January 1990 to December 2014 were analyzed. Results: Salivary gland epithelial tumors were found in 360 cases (55.3%) in the parotid gland, including 296 (82.2%) with benign tumors and 64 (17.8%) with malignant tumors. The ratio of male to female incidence was 0.7. Higher than male (170/126), the incidence of malignant salivary gland epithelial tumors in males than in females (36/28); benign salivary gland tumors into the high incidence of age after 30 years of age, malignant salivary gland epithelial tumors more than 50 years of age were more common. Benign salivary gland epithelial tumors in the top two were pleomorphic adenomas and Warthin tumors, and malignant tumors in the top two are acinar cell carcinoma and adenoid cystic carcinoma. Conclusions: The incidence of salivary gland epithelial tumors is on an upward trend. The parotid gland is a predilection site for salivary gland epithelial tumors. Polymorphic adenoma is the most common benign epithelial tumor in salivary glands, with less incidence of salivary gland epithelial malignancies. Cell carcinoma is more common than other malignancies.
