【摘要】:背景與目的:隨著高分辨率計(jì)算機(jī)斷層掃描(high-resolution computed tomography,HRCT)應(yīng)用的普及,同時(shí)性多原發(fā)肺癌(synchronous multiple primary non-small cell lung cancers,SMPLC)的檢出率逐年上升,但只有一些大型醫(yī)院具有一定的治療經(jīng)驗(yàn),目前仍有一些醫(yī)師缺乏對(duì)SMPLC的認(rèn)識(shí),而僅僅把SMPLC患者根據(jù)第7版和第8版TNM分期,許多患者被按照轉(zhuǎn)移癌過(guò)度分期為Ⅲ/Ⅳ期,因而失去了手術(shù)治療的機(jī)會(huì)。美國(guó)國(guó)立綜合癌癥網(wǎng)絡(luò)(National Comprehensive Cancer Network,NCCN)非小細(xì)胞肺癌治療指南(2017,第2版)指出,若無(wú)手術(shù)禁忌,SMPLC患者應(yīng)首選手術(shù)治療。本研究對(duì)我院胸外科43例SMPLC患者的外科治療進(jìn)行回顧性分析,為臨床診療提供依據(jù)。方法:2012年11月至2016年7月期間,共有43例臨床資料保存完整的且符合Martini-Melamed診斷標(biāo)準(zhǔn)的SMPLC患者于山東省立醫(yī)院胸外科行手術(shù)治療。我們對(duì)其臨床病理學(xué)特征包括性別、年齡、家族史、吸煙史、腫瘤數(shù)量、淋巴結(jié)轉(zhuǎn)移、手術(shù)方式、病理分期、基因突變等與生存分析的關(guān)系進(jìn)行了深入的分析。結(jié)果:43例患者中,男性17例,女性26例。34例患者有2個(gè)腫瘤病灶,9例患者腫瘤病灶數(shù)量超過(guò)兩個(gè)。29例患者腫瘤病灶位于一側(cè)肺,14例患者腫瘤病灶位于雙側(cè)肺。38例患者腫瘤病灶全為腺癌。11例雙側(cè)肺部腫瘤病灶的患者進(jìn)行了同期雙側(cè)手術(shù),術(shù)后平均住院日為9.36天,其余單側(cè)肺部腫瘤病灶患者術(shù)后平均住院日為8.79天,兩組患者術(shù)后平均住院日差異無(wú)統(tǒng)計(jì)學(xué)意義(P=0.512)。5例患者對(duì)不同腫瘤病灶分別進(jìn)行了基因檢測(cè),結(jié)果證實(shí)不同的腫瘤病灶生長(zhǎng)因子受體(EGFR)基因突變型不完全一致。1年和3年總生存率(overall survival,OS)分別為 97%和 76.7%。1 年和 3 年無(wú)病生存率(disease free survival,DFS)分別為92.1%和57.9%。單因素分析示腫瘤直徑越大(P=0.015)、病灶實(shí)性成分越多(P=0.005)、淋巴結(jié)轉(zhuǎn)移(P=0.002)、TNM分期越高(P=0.013)與較差的OS相關(guān)。腫瘤直徑越大(P=0.002)、病灶不全為腺癌(P=0.002)、與較差的DFS相關(guān)。38例同時(shí)性多原發(fā)肺腺癌(synchronous multiple primary lung adenocarcinomas,SPLA)患者中,男性12例,女性26例。雙原發(fā)肺腺癌29例,2個(gè)病灶以上9例。病灶位于同側(cè)26例,雙側(cè)12例。1年和3年總生存率分別為96.6%和74.2%。1年和3年的無(wú)病生存率分別為93.6%和71.8%。單因素分析示腫瘤直徑越大(P0.001)、淋巴結(jié)轉(zhuǎn)移(P=0.001)、TNM分期越高(P=0.022)以及術(shù)后放、化療(P=0.009)與較差的OS有關(guān)。腫瘤直徑越大(P0.001)、淋巴結(jié)轉(zhuǎn)移(P0.046)與較差的DFS有關(guān)。結(jié)論:對(duì)于多發(fā)的非小細(xì)胞肺癌,不能輕易地診斷為轉(zhuǎn)移癌,應(yīng)考慮多原發(fā)可能。EGFR基因檢測(cè)可作為鑒別多原發(fā)肺腺癌與復(fù)發(fā)轉(zhuǎn)移癌的臨床參考。
