【摘要】 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。更多还原

【Abstract】 Objective:To investigate clinicopathological characteristics such as the type of histology,the constituent ratio,the distribution of sex and recurrence of submandibuar gland tumors.Method:The clinical and pathological data of 96 cases with submandibular gland tumors in elder were statistically analysed.Result:71 cases(73.96 %) w ere benign epithelial tumor s;25 cases(26.04 %) w ere malig nant epithelial tumors;Pleomorphic adenoma was the top one of benign epithelial tumors.Adenoid cystic carcinoma was the top one of malignant epithelial tumors.The ratio of male to female of benign and malignant epithelial tumors was 0.92:1 and 1.5:1.The recurrence rate of submandibular gland tumors was 4.17 %,among w hich the recurrent pleomorphic adenoma accounted 75 %.Conclusion: Pleomorphic adenoma and adenoid cystic carcinoma are the most common type of benign and malignant epithelial submandibular gland tumors.Benign epithelial tumors are more common in women,while malignant epithelial tumors are more common in men.Recurrences appear to be much more likely in pleomorphic adenoma.更多还原
