腮腺多原发性肿瘤54例临床分析

Analysis of 54 cases with multiple primary tumors in parotid gland

目的了解腮腺多原发肿瘤临床特点、病理类型及生存现状。方法分析腮腺多原发肿瘤病理类型、患者性别、年龄、生活习惯等。结果所分析病例中腺淋巴瘤占56％（30例），其次为混合瘤占20％（11例）。单侧35例，双侧19例，同时性肿瘤44例，异时性肿瘤10例，男女比例为2．6：1，平均年龄58岁（23～80岁），34例嗜好吸烟，70％采用了保留面神经的瘤体及腮腺浅叶切除术。结论腮腺多原发性肿瘤大多数为腺淋巴瘤，其次为多形性腺瘤，男性好发，吸烟是该病重要致病因素，保留面神经的瘤体及腮腺浅叶切除术为最佳治疗方式。

Objective To study the clinical characteristics ,the type of pathology and life status of the multiple primary tumors in parotid gland. Methods To analyze the multiple primary tumors in parotid gland about the type of pathology, sex, age, smoking and drinking history, etc. Results Most of the multiple primary tumors in parotid gland are adenolymphoma accounted for 56 percent （ 30 ease）, the following are pleomorphic adenoma accounted for 20 percent（ 11 case）, 35 patients were unilateral parotid, 19 patients were bilateral parotid. The tumors were found and diagnosed synchronously in 44 patients, and metachronously in 10 patients ; the male ： female ratio of the multiple primary tumors is 2.6： 1. The median age was 58 years （range 23 to 80 years）. 34 patients were heavy smokers, 70% of all patients are taken lateral parotidectomy. Conclusion Most of the multiple primary tumors in parotid gland are adenolymphoma, the following are pleomorphic adenoma. The multiple primary tumors were more common in men, smoking was a very important malgenic factor,and lateral parotidectomy was an optimal treatment of these tumors.
