目的探讨涎腺恶性上皮性肿瘤的临床病理特点和各类肿瘤的构成比例。方法收集经病理确诊的涎腺恶性上皮性肿瘤373例,并对其临床资料进行回顾性分析。结果在373例病例中,男性184例,女性189例,男女之比为0.97∶1;患者平均年龄为48.9岁,发病高峰为41～50岁,多发年龄段为31～70岁;发病部位前四位依次为腮腺、腭腺、颌下腺及颊腺;最常见的四种病理类型依次为腺样囊性癌、黏液表皮样癌、非特异性腺癌和多形性腺瘤癌变。结论涎腺上皮性恶性肿瘤多见于中老年人,发病部位中以腮腺最多,同时腭腺、颌下腺多见,病理类型中以粘液表皮样癌、腺样囊性癌、非特异性腺癌、多形性腺瘤癌变最为多见。
Objective To investigate the clinicopathological characteristics of malignant salivary gland tumors and the proportions of various tumor types. Methods 373 cases of pathologically confirmed malignant salivary gland tumors were collected and their clinical data were retrospectively analyzed. Results In 373 cases, there were 184 males and 189 females, the ratio of male to female was 0.97:1. The mean age of patients was 48.9 years old, the peak incidence was 41-50 years old and the multiple age range was 31-70 years old. Four followed by the parotid gland, the palatine gland, the submandibular gland and the buccal gland. The most common four pathological types were adenoid cystic carcinoma, mucoepidermoid carcinoma, non-specific adenocarcinoma and pleomorphic adenoma. Conclusions Salivary gland epithelial malignancies are more common in the middle-aged and elderly patients. Most of the parotid glands are found in the pathogenesis sites, while the palatal glands and submandibular glands are common. The pathological types are mucoepidermoid carcinoma, adenoid cystic carcinoma, non-specific adenocarcinoma, Malignant adenoma is the most common.
