摘要:

目的 探讨奥希替尼与埃克替尼治疗转移性非小细胞肺癌(NSCLC)在真实世界的疗效。方法 回顾性分析2018年3月—2022年5月在武汉大学人民医院确诊的151例表皮生长因子受体(EGFR)阳性晚期NSCLC初诊患者的临床资料,根据治疗方法分为奥希替尼组(53例)和埃克替尼组(98例)。比较两组客观缓解率(ORR)、疾病控制率(DCR)、无进展生存期(PFS)及总生存期(OS);采用Cox回归模型分析预后的影响因素;并按照转移部位及EGFR突变类型进行亚组分析。结果 奥希替尼组和埃克替尼组患者的ORR分别为56.6%(30/53)、59.2%(58/98),差异无统计学意义(χ2=0.09,P=0.759);两组患者的DCR分别为83.0%(44/53)、91.8%(90/98),差异无统计学意义(χ2=2.68,P=0.102)。奥希替尼组和埃克替尼组患者的中位PFS分别为11.7、11.8个月,差异无统计学意义(χ2=0.06,P=0.802);两组患者的中位OS均为未达到,差异无统计学意义(χ2<0.01,P=0.969)。多因素分析结果显示肾上腺转移(HR=1.89,95%CI为1.04~3.41,P=0.036)为患者PFS的独立预后因素;性别(HR=2.22,95%CI为1.08~4.58,P=0.031)和肾上腺转移(HR=4.87,95%CI为1.76~13.46,P=0.002)为患者OS的独立预后因素。亚组分析结果显示,在胸膜转移(中位PFS:11.7个月比9.3个月,中位OS:未达到比未达到)、肾上腺转移(中位PFS:8.7个月比5.6个月,中位OS:20.0个月比15.3个月)、19DEL突变(中位PFS:14.5个月比13.3个月,中位OS:未达到比40.7个月)患者中,奥希替尼组倾向于有更好的生存结局;相反,在对侧肺转移(中位PFS:8.3个月比11.2个月,中位OS:未达到比40.7个月)、骨转移(中位PFS:11.7个月比11.8个月,中位OS:未达到比34.5个月)、肝转移(中位PFS:8.7个月比9.1个月,中位OS:未达到比23.8个月)、脑转移(中位PFS:11.7个月比15.3个月,中位OS:22.4个月比35.3个月)和21L858R突变(中位PFS:9.5个月比10.0个月,中位OS:22.4个月比未达到)患者中,埃克替尼组倾向于有更好的生存结局,但差异均无统计学意义(均P>0.05)。结论 奥希替尼和埃克替尼对EGFR阳性晚期NSCLC患者都具有良好的治疗效果,两者均可作为一线治疗的选择。

Abstract:

Objective To investigate the real-world efficacy of osimertinib and icotinib in metastatic non-small cell lung carcinoma (NSCLC) patients. Methods A retrospective analysis was performed on clinical data of 151 newly-diagnosed patients with epidermal growth factor receptor (EGFR)-positive advanced NSCLC in Renmin Hospital of Wuhan University from March 2018 to May 2022. The patients were divided into osimertinib group (n=53) and icotinib group (n=98) according to treatment method. The objective response rate (ORR),disease control rate (DCR),progression-free survival (PFS) and overall survival (OS) were compared between the two groups. The factors influencing prognosis were analyzed by using Cox regression models. Subgroup analysis was performed according to metastatic site and EGFR mutation type. Results ORR was 56.6% (30/53) and 59.2% (58/98) for patients in the osimertinib group and icotinib group,respectively,with no statistically significant difference (χ2=0.09,P=0.759). DCR was 83.0% (44/53) and 91.8% (90/98) for patients in the osimertinib group and icotinib group,respectively,with no statistically significant difference (χ2=2.68,P=0.102). The median PFS was 11.7 months and 11.8 months for patients in the osimertinib group and icotinib group,respectively,with no statistically significant difference (χ2=0.06,P=0.802). The median OS was not reached for patients in both the osimertinib group and icotinib group,with no statistically significant difference (χ2<0.01,P=0.969). The results of multivariate analysis showed that adrenal metastases (HR=1.89,95%CI: 1.04-3.41,P=0.036) was an independent prognostic factor for PFS. Gender (HR=2.22,95%CI: 1.08-4.58,P=0.031) and adrenal metastases (HR=4.87,95%CI: 1.76-13.46,P=0.002) were independent prognostic factors for OS. The results of the subgroup analysis showed that in patients with pleural metastases (median PFS: 11.7 months vs. 9.3 months,median OS: not reached vs. not reached),adrenal metastases (median PFS: 8.7 months vs. 5.6 months,median OS: 20.0 months vs. 15.3 months),19DEL mutations (median PFS: 14.5 months vs. 13.3 months,median OS: not reached vs. 40.7 months),the osimertinib group tended to have better survival outcomes. Conversely,in patients with contralateral lung metastases (median PFS: 8.3 months vs. 11.2 months,median OS: not reached vs. 40.7 months),bone metastases (median PFS: 11.7 months vs. 11.8 months,median OS: not reached vs. 34.5 months),liver metastases (median PFS: 8.7 months vs. 9.1 months,median OS: not reached vs. 23.8 months),brain metastases (median PFS: 11.7 months vs. 15.3 months,median OS: 22.4 months vs. 35.3 months) and 21L858R mutations (median PFS: 9.5 months vs. 10.0 months,median OS: 22.4 months vs. not reached),the icotinib group tended to have better survival outcomes,but with no statistically significant differences (all P>0.05). Conclusion Both osimertinib and icotinib have good therapeutic efficacy in patients with EGFR-positive advanced NSCLC,thus can be used as first-line treatment options.
