31例复发性腮腺腺样囊性癌临床分析

目的探讨腮腺腺样囊性癌诊断及复发癌治疗方法。方法对31例复发性腮腺腺样囊性癌作临床分析。结果局部切除或浅叶切除复发时间比全腮腺切除复发时间短。复发后采用手术 放疗比单纯手术的疗效好。颈淋巴结转移率低,本组为10.3%(3/29)。结论B超、CT及肿瘤穿刺细胞学检查有助术前诊断。全腮腺切除应视为常规,术后复发可采用扩大切除术,但应补充放疗。预防性颈淋巴结清除术不应视为常规。

A Clinical Study of 31 Cases with Recurrent Adenoid Cystic Carcinoma of Parotid Gland

Objective To research diagnosis of adenoid cystic carcinoma of parotid gland and treatment methods of recurrent carcinoma.Method 31 cases with recurrent adenoid cystic carcinoma of parotid gland were studied.Results The patients treated with local resection and superficial lobectomy recurred more earlier than those treated with total parotid resection. To recurrent cases the synthesized radiotherapeutics could get a better therapeutic effect. The metastasis rate of neck lymphonode was 10.3%; it was very low.Conclusion Ultrasonic examination of type B, computer tomography, and fine needle aspiration is very useful in preoperative diagnosis. Total parotid resection should be considered as a regular treatment. To recurrent cases to extend resection could be done, but should be synthesized radiation. Prophylatic radical neck dissection should not be considered as a regular therapeutic method.
