No definite conclusion has yet to be reached for the first-line treatment combined with chemotherapy for advanced adenocarcinoma NSCLC patients with negative driver genes. This study sought to compare the clinical outcomes of Beva+ChT and IO+ChT as first-line treatment for this population and investigated whether the statuses of BM, PD-L1 expression, and KRAS and TP53 mutations could influence the results.
The clinical data of patients with adenocarcinoma NSCLC who received first-line therapy were retrospectively collected and the patients were assigned to the IO+ChT and Beva+ChT groups. The disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) were evaluated between the two groups. The survival effects of BM, PD-L1 expression, and KRAS and TP53 mutations were also evaluated.
From April 2018 to October 2020, a total of 105 patients with first-line therapy were included in our analysis; 54 (51.4%) patients were included in the IO+ChT group and 51 (48.6%) patients were included in the Beva+ChT group. The results showed that OS (NR vs. 18.3 m, p = 0.011) and PFS (14.9 m vs. 6.3 m, p < 0.001) were superior in patients in the IO+ChT group than in patients in the Beva+ChT group. Further analysis revealed that the OS (median OS: NR vs. 14.7 months, p = 0.039) and PFS (median PFS: 18.5 vs. 5.5 months, p < 0.001) advantages of the IO+ChT group were also seen in the PD-L1 > 1% subgroup but were not seen in the PD-L1 < 1%, BM or KRAS mutation subgroups.
ICIs combined with ChT improved clinical outcomes over Beva combined with ChT as first-line therapy for adenocarcinoma patients without driver gene alterations, especially in patients with PD-L1 ≥ 1%.
对于携带阴性驱动基因的晚期非小细胞肺癌(NSCLC)腺癌患者,联合化疗的一线治疗方案尚无明确结论。本研究旨在比较贝伐珠单抗联合化疗(Beva+ChT)和免疫检查点抑制剂(IO)联合化疗(IO+ChT)作为此类患者一线治疗的临床疗效,并探讨骨髓(BM)状态、程序性死亡配体 1(PD-L1)表达、KRAS 和 TP53 突变是否会影响结果。
回顾性收集接受一线治疗的腺癌 NSCLC 患者的临床资料,并将患者分为 IO+ChT 组和 Beva+ChT 组。评估两组间疾病控制率(DCR)、无进展生存期(PFS)和总生存期(OS)。还评估了 BM、PD-L1 表达、KRAS 和 TP53 突变对生存的影响。
2018 年 4 月至 2020 年 10 月,共纳入 105 例接受一线治疗的患者,其中 IO+ChT 组 54 例(51.4%),Beva+ChT 组 51 例(48.6%)。结果显示,IO+ChT 组患者的 OS(NR 与 18.3 m,p=0.011)和 PFS(14.9 m 与 6.3 m,p<0.001)均优于 Beva+ChT 组。进一步分析显示,在 PD-L1>1%亚组中,IO+ChT 组的 OS(中位 OS:NR 与 14.7 个月,p=0.039)和 PFS(中位 PFS:18.5 与 5.5 个月,p<0.001)也具有优势,但在 PD-L1<1%、BM 或 KRAS 突变亚组中则无优势。
对于无驱动基因改变的腺癌患者,与贝伐珠单抗联合化疗相比,ICI 联合化疗作为一线治疗可改善临床结局,特别是在 PD-L1≥1%的患者中。
