目的:了解老年患者颌下腺肿瘤的组织学类型及临床病理特征。方法:对96例老年患者颌下腺肿瘤临床病理资料进行统计学分析。结果:良性上皮性肿瘤71例(73.96%),恶性上皮性肿瘤25例(26.04%)。多形性腺瘤居良性上皮性肿瘤的首位,腺样囊性癌居恶性上皮性肿瘤的首位。良、恶性上皮性肿瘤的男女性别比为0.92:1和1.5:1;良性肿瘤平均年龄66岁、恶性肿瘤平均年龄69岁。颌下腺肿瘤复发率为4.17%,多形性腺瘤占75%。结论:多形性腺瘤和腺样囊性癌分别是最常见的良、恶性上皮性肿瘤;良性上皮性肿瘤多见于女性,恶性上皮性肿瘤多见于男性;多形性腺瘤易复发。
Objective: To understand the histological type and clinicopathological features of submandibular gland tumors in elderly patients. Methods: A total of 96 elderly patients with submandibular gland tumor clinical and pathological data were analyzed. Results: There were 71 cases (73.96%) of benign epithelial tumors and 25 cases (26.04%) of malignant epithelial tumors. Pleomorphic adenoma ranks first in benign epithelial tumors, adenoid cystic carcinoma ranks first in malignant epithelial tumors. The ratio of male to female in benign and malignant epithelial tumors was 0.92: 1 and 1.5: 1. The average age of benign tumors was 66 years and the average age of malignant tumors was 69 years. Submandibular gland tumor recurrence rate was 4.17%, pleomorphic adenomas accounted for 75%. Conclusions: Pleomorphic adenoma and adenoid cystic carcinoma are the most common benign and malignant epithelial tumors respectively. Benign epithelial tumors are more common in women. Malignant epithelial tumors are more common in men. Pleomorphic adenomas are easy to relapse.
