Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are approved for second-line treatment of wild-type (-wt) nonsmall cell lung cancer (NSCLC). However, results from randomised trials performed to compare EGFR-TKIs with chemotherapy in this population did not show any survival benefit. In the era of immunotherapy, many drugs are approved for second-line treatment of wt NSCLC and there is a need to reassess the role of EGFR-TKIs in this setting.The Biomarkers France study is a large nationwide cohort of NSCLC patients tested for mutations. We used this database to collect clinical, biological, treatment and outcome data on wt patients who received second-line treatment with either EGFR-TKIs or chemotherapy.Among 1278 patients, 868 received chemotherapy and 410 received an EGFR-TKI. Median overall survival and progression-free survival were longer with chemotherapy than with an EGFR-TKI. Overall survival was 8.38 4.99 months, respectively (hazard ratio 0.70, 95% CI 0.59-0.83; p<0.0001) and progression-free survival was 4.30 2.83 months, respectively (hazard ratio 0.66, 95% CI 0.57-0.77; p<0.0001).This study is helpful to guide a multiline treatment strategy for wt NSCLC patients. Immunotherapy is approved for second-line treatment. For third-line treatment, chemotherapy results in longer overall survival and progression-free survival, and should be preferred to EGFR-TKIs.
表皮生长因子受体酪氨酸激酶抑制剂 (EGFR-TKIs) 获批用于野生型 (-wt) 非小细胞肺癌 (NSCLC) 的二线治疗。然而,在该人群中进行的比较 EGFR-TKIs 与化疗的随机试验结果并未显示任何生存获益。在免疫治疗时代,许多药物获批用于 wt NSCLC 的二线治疗,因此需要重新评估 EGFR-TKIs 在这种情况下的作用。
Biomarkers France 研究是一项针对 NSCLC 患者进行 突变检测的大型全国性队列研究。我们利用该数据库收集了接受 EGFR-TKIs 或化疗二线治疗的 wt 患者的临床、生物学、治疗和结局数据。
在 1278 名患者中,868 名接受化疗,410 名接受 EGFR-TKI。与 EGFR-TKI 相比,化疗的中位总生存期和无进展生存期更长。总生存期分别为 8.38 4.99 个月(风险比 0.70,95%CI 0.59-0.83;p<0.0001)和无进展生存期分别为 4.30 2.83 个月(风险比 0.66,95%CI 0.57-0.77;p<0.0001)。
这项研究有助于指导 wt NSCLC 患者的多线治疗策略。免疫治疗获批用于二线治疗。对于三线治疗,化疗可延长总生存期和无进展生存期,应优先考虑化疗而非 EGFR-TKIs。
