1、肺混合型神经内分泌癌的临床特征摘要:目的:探讨混合型神经内分泌肿瘤的发生部位、诊断、治疗及生存情况。方法:通过检索近2年來我院胸部肿瘤科连续收治入院的2501例肺癌患者的临床资料,回顾性分析其确诊方法、组织分类,进一步探讨木病的危险因素、临床治疗及转归。结果:2501例原发肺癌,其中混合型神经内分泌癌20例,发生率为0.01%(男:女=19:1)。中位年龄60岁。手术和化疗是主要治疗方式,分别有13例(65%)及19例(95%)病人接受了手术及化疗。另有2例(10%)病人接受过胸部放疗(剂量50Gy/5
2、6Gy),3例(15%)脑转移病人接受了头部姑息照射。化疗方案包括SCLC常用方案(依托泊背二联化疗方案)、(NSCLC)常用方案即笫三代化疗药物(紫杉醇等)单药或联合化疗。经电话随访得到18例病人(随访率90%)的生存资料。中位随访时间20.5月。中位OS未达到,其中I〜III期病人的中位OS未达到,IV期中位OS为18.2月,两组養界未能达到统计学意义(P=0.245)。按照病理分型,复合型SCLC屮位OS为18.2月,其他混合类型的中位OS未达到,差异没有统计学意义(P=0.325)。不同化疗方案
3、(SCLC或NSCLC方案)对中位OS无明显影响(P=0.535)。按照是否手术分组,手术组11例死亡0例(0%),未于术组7例死亡6例(85.7%),两组差异有统计学意义(P<0.001)o结论:肺混合型神经内分泌肿瘤是少见类型的肺原发肿瘤,男性病人居多,可混合其他各种肿瘤成分。肿瘤分期及分化程度对预后冇明显影响。就治疗方式而言,釆用SCLC或NSCLC方案化疗对预后无明显影响。能否手术对长期生存至关重要。关键词:肿瘤学;神经内分泌肿瘤;泯合型癌;病理分型;治疗中图分类号:R734.2Clinical
