             [摘    要] 目的:观察表皮生长因子受体(epidermal growth factor receptor,EGFR)21 外显子突变的晚期非小细胞肺癌(non⁃
              small cell lung cancer,NSCLC)患者在接受埃克替尼单药或联合含铂双药化疗一线治疗中与EFGR19外显子突变患者的疗效差
              异。方法:回顾性分析2012年8月—2020年10月南京医科大学第一附属医院收治的174例EGFR 突变阳性初治晚期NSCLC
              患者,其中EGFR21外显子突变82例,38例埃克替尼单药治疗,44例埃克替尼联合含铂双药治疗;EGFR19外显子突变92例,
              43例埃克替尼单药治疗,49例埃克替尼联合含铂双药化疗。分别比较EGFR21及19突变患者在两组治疗方案中的客观缓解
              率(objective response rate,ORR)、疾病控制率(disease control rate,DCR)、无进展生存期(progression⁃free survival,PFS)、总生存
              期(overall survival,OS)的差异。结果:埃克替尼单药治疗的患者中,EGFR21外显子突变患者的中位PFS较EGFR19外显子突
              变患者减少3.5个月(9.5个月vs. 13.0个月,P=0.046),中位OS、治疗1个周期后ORR、DCR无显著差异(P > 0.05)。埃克替尼联
              合含铂双药化疗的患者中,EGFR21外显子突变患者较19外显子突变患者PFS、OS、治疗1周期后ORR、DCR无显著差异(P >
              0.05)。EGFR21外显子突变患者中,联合组中位PFS较单药组延长5.8个月(15.3个月vs. 9.5个月,P=0.002),中位OS较单药组
              延长20.2个月(46.0个月vs. 25.8个月,P=0.004),两组患者治疗1周期后ORR、DCR无显著差异(P > 0.05)。EGFR19外显子突
              变患者中,联合组中位PFS较单药组延长9.1个月(22.1个月vs. 13.0个月,P < 0.001),中位OS较单药组延长35个月(61.0个月
              vs. 26.0个月,P < 0.001),两组患者治疗1周期后ORR、DCR无显著差异(P > 0.05)。结论:对于EGFR敏感突变的晚期NSCLC
              患者,埃克替尼联合化疗一线治疗对比埃克替尼单药治疗,可显著改善PFS及OS,尤其应用于21外显子突变患者中可取得与
              19外显子突变患者相当的PFS及OS。

              Comparison of clinical outcomes of NSCLC patients harbouring EGFR exon 21 or exon

             [Abstract] Objective:This study compared prognoses of advanced non⁃small cell lung cancer patients with epidermal growth factor
              receptor exon 19 or 21 mutations after two types of first ⁃ line treatment:Icotinib hydrochloride alone or icotinib combined with
              chemotherapy. Methods:The clinical data of 174 patients admitted to the First Affiliated Hospital of Nanjing Medical University from
              August 2012 to October 2020 were retrospectively analyzed. Totally,82 cases carried EGFR 21 exon mutation,38 cases received first⁃
              line Icotinib therapy,while 44 cases received icotinib combined with the chemotherapy. 92 cases were with the presence of EGFR19
              exon mutation,43 cases received first⁃line icotinib therapy,and 49 cases received iotinib combined with chemotherapy. We compared
              differences in objective response rate,disease control rate,progression⁃free survival,and overall survival between EGFR 21 and 19
              exon mutation patients after receiving different treatment regimens. Results:Among the patients receiving icotinib treatment,the
