Background: The proportion of never?smokers with non?small cell lung cancer(NSCLC) is increasing, but that in Korea has not been well addressed in a large population. We aimed to evaluate the proportion and clinical features of never?smokers with NSCLC in a large single ***: We analyzed clinical data of 1860 consecutive patients who were newly diagnosed with NSCLC between June 2011 and December ***: Of the 1860 NSCLC patients, 707(38.0%) were never?smokers. The proportions of women(83.7% vs. 5.6%) and adenocarcinoma(89.8% vs. 44.9%) were higher among never?smokers than among ever?smokers. Significantly more never?smokers were diagnosed at a younger median age(65 vs. 68 years, P < 0.001) and earlier stage(stage I–II, 44.5% vs. 38.9%, P < 0.001) a= 0.015) compared with ever?smokers. Epidermal growth factor receptor mutations(57.8% vs. 24.4%, Pnd anaplastic lymphoma kinase rearrangements(7.8% vs. 2.8%, P < 0.001) were more common in never?smokers, whereas Kirsten rat sarcoma viral oncogene homolog mutations(5.8% vs. 9.6%, P ntly encountered in never?smokers than in ever?smokers. Never?smokers showed longer su= 0.021) were less frequervival after adjust?ing for the favorable effects of younger age, female sex, adenocarcinoma histology, better performance status, early stage disease, being asymptomatic at diagnosis, received antitumor treatment, and the presence of driver mutations(hazard ratio, 0.624; 95% confidence interval, 0.460–0.848; P = 0.003).Conclusions: More than one?third of the Korean patients with NSCLC were never?smokers. NSCLC in never?smokers had different clinical characteristics and major driver mutations and resulted in longer overall survival compared with NSCLC in ever?smokers.

背景与目的非小细胞肺癌(non?small cell lung cancer, NSCLC)患者中非吸烟患者的比例正在增加,但在韩国,这个人数众多的群体并没有得到很好的治疗。本研究旨对NSCLC非吸烟患者的比例和临床特征进行一个单中心评估。方法我们分析了从2011年6月到2014年12月所有新诊断为NSCLC的1860例患者的临床数据。结果在1860例NSCLC患者中,707例(38%)从不吸烟。非吸烟患者中女性(83.7%vs.5.6%)和腺癌(89.8%vs. 44.9%)的比例均高于吸烟患者。非吸烟患者与吸烟患者相比,中位年龄明显更低(65 vs. 68岁,P<0.001),早期肿瘤比例更高(I–II期,44.5%vs. 38.9%,P=0.015)。与吸烟患者相比,表皮生长因子受体突变(57.8%vs. 24.4%,P<0.001)和间变性淋巴瘤激酶重排(7.8%vs. 2.8%,P<0.001)在非吸烟患者中更常见,而Kirsten大鼠肉瘤病毒癌基因同源染色体的基因突变(5.8%vs. 9.6%,P=0.021)出现频率则较低。在对年龄低、女性、腺癌、体能更好、疾病早期、诊断时无症状、曾接受抗肿瘤治疗以及存在驱动基因突变等的有利影响进行校正后,非吸烟患者的生存期比吸烟患者更长(hazard ratio,0.624,95%CI:0.460–0.848; P=0.003)。结论韩国超过三分之一的NSCLC患者是非吸烟者。NSCLC非吸烟患者与吸烟患者相比,有着不同的临床特征和主要驱动基因突变,总生存期更长。
