腮腺腺泡细胞癌29例临床分析

目的：总结肋腺腺泡细胞癌的临床特点、生物学行为及治疗效果。方法：对29例肋腺腺泡细胞癌病者进行临床分析。结果：腮腺腺泡细胞癌的临床特点为男女发病均等，各年龄组均可发病，好发于腮腺浅叶，生长缓慢，病程长，平均为5年，颈淋巴结转移率为17．2％，极少发生远处转移，局部复发率为20．75，预后相对较好，其3、5、10年生存率分别为82．7％、80％和76．9％。结论：腮腺腺泡细胞癌发病少，属低度恶性肿瘤，其治疗以根治性手术切除为主，病变范围广或复发病例可行术后放疗以减少局部复发。

A Clinical Analysis of 29 Patients with Acinic Cell Carcinoma of Parotid

Objective: This study was designed to summarize the clinical characteristics, biological behavior, and treatment results of acinic cell carcinoma of parotid. Method: Twenty-nine cases of acinic cell carcinoma of parotid were collected to make clinical analysis. Results: The clinical feature of acinic cell carcinoma of parotid were observed as following: the incidence of male and female was equal and happen in any age group. The tumor usual located at superficial lobe of parotid, and growth slowly. The course was long with a mean of 5 years. The incidence of cervical lymph node metastasis was 17. 2% and distant metastasis was much less, the local recurrence rate was 20. 7% and the prognosis was relatively better. The survival rates of 3-year, 5-year, 10-year were 82. 7%, 80%, and 76. 9%, respectively. Conclusion: The incidence of acinic cell carcinoma of parotid is low, and acinic cell carcinoma of parotid could be considered as lower malignant tumor. Radical surgical ressection is the most common modality for its treatment, while larger lesion or recurrent cases may receive postoperative radiotherapy so as to decrease local recurrence.
