喉部神经内分泌癌的诊断和治疗

目的 总结喉部神经内分泌癌的临床特征.方法 回顾性分析1988年6月至2010年12月在我院耳鼻喉科诊治的喉部神经内分泌癌患者的临床资料.结果 12例经病理确诊为喉部神经内分泌癌患者中,典型类癌1例,非典型类癌4例(2例伴有颈部淋巴结转移,1例伴有类癌综合征),小细胞神经内分泌癌7例(1例合并腺癌).典型类癌和非典型类癌患者均接受手术治疗,其中局部晚期或伴有颈淋巴结转移的患者接受术后放疗,随诊1～12年均未见局部复发.7例小细胞神经内分泌癌患者接受化疗和放疗,随访0.5～6.0年,其中1例半年内死于肺转移,另1例3年内死于肝转移.结论 喉部神经内分泌癌的病理分型和临床分期对于治疗和预后非常重要.典型类癌和非典型类癌采取喉部分或全部切除术,必要时行颈淋巴清扫术;小细胞神经内分泌癌预后差,治疗以化疗和放疗为主.

Abstract：

Objective To summarize the clinical features of laryngeal neuroendocrine carcinoma (LNEC).Methods The clinical data of all LNEC patients hospitalized during the period of June 1988-December 2010 were analyzed retrospectively.Results Among all LNEC 12 patients as confirmed by pathological examination,there were typical earcinoid(n=1),atypical earcinoid(n=4)(2 with cervical metastasis.1 with paraneoplastic syndrome),small cell neuroendocfine carcinoma(n=7)(1 with adenocarcinoma).All patients with typical and atypical carcinoid underwent surgery.And postoperative radiotherapy was offered for those diagnosed with advanced stage or cervical metastasis.They were followed up for 1-12 years without local recurrence.All patients with laryngeal small cell neumendocrine carcinoma received chemotherapy and radiotherapy.And the follow-up period was 0.5-6 years.One died of pulmonary metastasis within half a year while another died of liver metastasis within 3 years.Conclusions It is important to classify the LNEC patients correctly since their clinical course.treatment and prognosis varies greatly with the diagnosis.For typical and atypical carcinoid of larynx,partial or total laryngectomy and neck dissection may be performed depending on the site and extent of primary tumor.However,for laryngeal small cell neuroendocrine carcinoma,the mainstay of treatment is made up of chemotherapy and radiotherapy.And the prognosis of this type remains very poor.
