【摘要】:背景与目的:随着高分辨率计算机断层扫描(high-resolution computed tomography,HRCT)应用的普及,同时性多原发肺癌(synchronous multiple primary non-small cell lung cancers,SMPLC)的检出率逐年上升,但只有一些大型医院具有一定的治疗经验,目前仍有一些医师缺乏对SMPLC的认识,而仅仅把SMPLC患者根据第7版和第8版TNM分期,许多患者被按照转移癌过度分期为Ⅲ/Ⅳ期,因而失去了手术治疗的机会。美国国立综合癌症网络(National Comprehensive Cancer Network,NCCN)非小细胞肺癌治疗指南(2017,第2版)指出,若无手术禁忌,SMPLC患者应首选手术治疗。本研究对我院胸外科43例SMPLC患者的外科治疗进行回顾性分析,为临床诊疗提供依据。方法:2012年11月至2016年7月期间,共有43例临床资料保存完整的且符合Martini-Melamed诊断标准的SMPLC患者于山东省立医院胸外科行手术治疗。我们对其临床病理学特征包括性别、年龄、家族史、吸烟史、肿瘤数量、淋巴结转移、手术方式、病理分期、基因突变等与生存分析的关系进行了深入的分析。结果:43例患者中,男性17例,女性26例。34例患者有2个肿瘤病灶,9例患者肿瘤病灶数量超过两个。29例患者肿瘤病灶位于一侧肺,14例患者肿瘤病灶位于双侧肺。38例患者肿瘤病灶全为腺癌。11例双侧肺部肿瘤病灶的患者进行了同期双侧手术,术后平均住院日为9.36天,其余单侧肺部肿瘤病灶患者术后平均住院日为8.79天,两组患者术后平均住院日差异无统计学意义(P=0.512)。5例患者对不同肿瘤病灶分别进行了基因检测,结果证实不同的肿瘤病灶生长因子受体(EGFR)基因突变型不完全一致。1年和3年总生存率(overall survival,OS)分别为 97%和 76.7%。1 年和 3 年无病生存率(disease free survival,DFS)分别为92.1%和57.9%。单因素分析示肿瘤直径越大(P=0.015)、病灶实性成分越多(P=0.005)、淋巴结转移(P=0.002)、TNM分期越高(P=0.013)与较差的OS相关。肿瘤直径越大(P=0.002)、病灶不全为腺癌(P=0.002)、与较差的DFS相关。38例同时性多原发肺腺癌(synchronous multiple primary lung adenocarcinomas,SPLA)患者中,男性12例,女性26例。双原发肺腺癌29例,2个病灶以上9例。病灶位于同侧26例,双侧12例。1年和3年总生存率分别为96.6%和74.2%。1年和3年的无病生存率分别为93.6%和71.8%。单因素分析示肿瘤直径越大(P0.001)、淋巴结转移(P=0.001)、TNM分期越高(P=0.022)以及术后放、化疗(P=0.009)与较差的OS有关。肿瘤直径越大(P0.001)、淋巴结转移(P0.046)与较差的DFS有关。结论:对于多发的非小细胞肺癌,不能轻易地诊断为转移癌,应考虑多原发可能。EGFR基因检测可作为鉴别多原发肺腺癌与复发转移癌的临床参考。
