615例小涎腺上皮性肿瘤的临床病理分析

目的　探讨小涎腺上皮性肿瘤的临床病理特点。方法　对615例小涎腺上皮性肿瘤的部位分布、发病年龄、性别及组织学类型进行回顾性分析。结果　615例小涎腺上皮性肿瘤中腺瘤265例,癌350例,良恶性肿瘤之比为1∶1·3。良性肿瘤中以多形性腺瘤最为常见(81·1%),其次为肌上皮瘤(14·7%)。恶性肿瘤中以腺样囊性癌最常见(32·9%),其次为粘液表皮样癌(21·4%),腺癌(11·7%)。小涎腺上皮性肿瘤以腭部最为好发,分别占良、恶性肿瘤的77·0%和60.0%。腺瘤中女性患者(51·3%)稍多于男性(48·7%);小涎腺癌患者中男性(56·3%)多于女性 (43·7%)。小涎腺腺瘤患者平均发病年龄40·9岁,小涎腺癌平均发病年龄49·1岁,恶性肿瘤的发病年龄显著高于良性肿瘤(P<0·05)。结论　小涎腺上皮性肿瘤在病理类型构成比、部位、年龄、性别分布上具有其独到的特点。

A Retrospective Study on 615 Cases of Minor Salivary Gland Tumors

OBJECTIVE: To analyse the clinical and pathological characteristics of minor salivary gland tumors. METHODS: A retrospective analysis on 615 cases of intraoral minor salivary gland tumors from 1990-2002 with a confirmed pathologic diagnosis was carried out. RESULTS: In 615 cases of minor salivary gland tumors, 265 cases were benign, 350 cases malignant. Pleomorphic adenoma was the most common entity and accounted for 81.1% of all benign tumors. Adenoid cystic carcinoma comprised 32.9% of the malignant sample and was the most frequent malignant tumor. The principal location was the palate. Female was a little more of the benign and a male prevalence was observed on the malignant tumor. The mean age of patients with benign and malignant tumors were 40.9 and 49.1 years old, respectively (P < 0.05). CONCLUSION: We consider extraordinary manifestation as histopathology, tumor, primary location, age and sex, presenting the results of a review of our experience with those minor salivary gland tumors.
