摘要: 目的 分析肺大细胞神经内分泌癌的临床资料,探讨相关预后因素,并初步回顾放射治疗对其预后的影响。方 法 回顾性分析37例1994年4月30日至2014年4月30日于北京协和医院就诊,病理确诊为肺大细胞神经内分泌癌患者的临床特征、诊治情况及预后。结 果 肺大细胞神经内分泌癌好发于有大量吸烟史的老年男性,临床表现、影像学表现及实验室指标缺乏特异性。神经内分泌分化标志物Syn、CgA和CD56的阳性表达率分别为75.7%、59.5%和67.6%。27例行手术治疗,术后17例接受辅助化疗,10例接受化疗,接受放疗者共8例,其中手术+化疗+放疗者4例,化疗+放疗组4例。单因素分析提示肿瘤TNM分期(P<0.01)是预后因素,对于非广泛期患者,手术(p<0.05)是预后的影响因素,对于III期患者,放疗是其预后的影响因素(p<0.05)。结论 肺大细胞神经内分泌癌缺乏特异性的临床表现,诊依赖术后病理,各种治疗疗效欠佳。手术对于局限期大细胞神经内分泌癌是影响预后的重要因素。放疗可能提高III期患者生存期。

Abstract: Objectives To investigate the clinical character of the large-cell neuroendocrine carcinomas(LCNECs), and analyze the clinical factors or treatment methods related to prognosis. Methods Collect the 37 patients data from 1994.4.30 to 2014.4.30 in our hospital(PUMCH), and analyzed retrospectively. Results LCNEC occurs in older men with heavy smoking history, clinical manifestations, imaging and laboratory examination lack of specificity. Immunohistochemically neuroendocrine specific markers Syn, CgA and CD56 positive expression rates were: 75.7%、59.5% and 67.6%, respectively. 27 patients receive surgical treatment, 10 patients received adjuvant chemotherapy, 8 underwent palliative radiotherapy. Univariate analysis indicated that tumor-node-metastasis (TNM) stage(P<0.01) is prognostic factor. Surgery is a prognostic factor for patients with limited term(p<0.05). for patients with stage III radiotherapy is a prognostic factor(p<0.05). Conclusion LCNEC lack specific clinical symptoms, diagnosis depends on pathology, the treatment effect is poor. TNM stage is an important prognostic factor. Surgery for the patients with limited stage affect the prognosis, radiotherapy for patients with stage III may improve the survival rate.
