摘要
目的探讨驱动基因阴性晚期非小细胞肺癌(NSCLC)患者一线免疫及其联合治疗进展后不同二线治疗策略在真实世界的疗效。方法回顾性分析2018年1月1日至2023年12月31日在新乡医学院第一附属医院、新乡市中心医院收治的93例一线行免疫及其联合治疗的驱动基因阴性晚期NSCLC患者的临床资料。根据一线治疗后无进展生存期(PFS)是否超过6个月,将患者分为免疫检查点抑制剂(ICI)耐药组(n=43)和ICI应答组(n=50);根据一线免疫及其联合治疗进展后的不同二线治疗策略,将患者分为ICI治疗组(n=55)和非ICI治疗组(n=38)、抗血管生成治疗组(n=51)和非抗血管生成治疗组(n=42)。比较各组患者二线治疗的中位PFS2(mPFS2)及中位总生存期(mOS)2。采用Kaplan-Meier法进行生存分析。结果93例一线ICI治疗后进展的晚期NSCLC患者的mPFS2为4.9个月(95%CI为4.1~5.7个月),mOS2为14.7个月(95%CI为11.2~18.2个月)。一线ICI应答组和ICI耐药组患者的mPFS2分别为6.0、3.8个月,差异无统计学意义(χ^(2)=2.00,P=0.157),mOS2分别为25.3、11.3个月,差异有统计学意义(χ^(2)=12.13,P<0.001)。二线ICI治疗组与非ICI治疗组患者的mPFS2分别为5.2、4.6个月,差异无统计学意义(χ^(2)=0.16,P=0.687),mOS2分别为15.1、12.7个月,差异无统计学意义(χ^(2)=0.01,P=0.930)。二线抗血管生成治疗组和非抗血管生成治疗组患者的mPFS2分别为4.5、6.0个月,差异无统计学意义(χ^(2)=0.41,P=0.525),mOS2分别为14.7、16.8个月,差异无统计学意义(χ^(2)=0.01,P=0.943)。结论驱动基因阴性晚期NSCLC患者一线ICI治疗进展后,一线ICI应答患者较ICI耐药患者二线治疗的OS显著延长。一线ICI治疗进展后患者二线治疗的疗效并不因治疗策略不同而存在差异。
Objective To explore the efficacy of different second-line treatment strategies in the real world after progression of first-line immunotherapy and its combination therapies in patients with driver genenegative advanced non-small cell lung cancer(NSCLC).Methods A retrospective analysis was conducted on the clinical data of 93 driver gene-negative advanced NSCLC patients who received first-line immunotherapy and its combination therapies from January 1,2018 to December 31,2023 at the First Affiliated Hospital of Xinxiang Medical University and Xinxiang Central Hospital.Patients were categorized into immune checkpoint inhibitors(ICIs)-resistant(n=43)and ICIs-responsive(n=50)groups according to whether progression free survival(PFS)exceeded 6 months after first-line treatment.Patients were categorized into ICIs-treated(n=55)and non-ICIs-treated(n=38),anti-angiogenic-treated(n=51)and non-anti-angiogenic-treated(n=42)groups according to the different second-line treatment strategies after progression of first-line immunotherapy and its combination therapies.The median PFS2(mPFS2)and median overall survival(mOS)2 after second-line treatment of each group were compared.The Kaplan-Meier method was used for survival analysis.Results The mPFS2 and mOS2 of 93 advanced NSCLC patients who progressed after first-line ICIs treatment were 4.9 months(95%CI:4.1-5.7 months)and 14.7 months(95%CI:11.2-18.2 months).The mPFS2 of patients in the firstline ICIs-responsive and ICIs-resistant groups were 6.0 and 3.8 months,respectively,with no statistically significant difference(χ^(2)=2.00,P=0.157),and the mOS2 were 25.3 and 11.3 months,respectively,with a statistically significant difference(χ^(2)=12.13,P<0.001).The mPFS2 of patients in the second-line ICIs-treated group and the non-ICIs-treated group were 5.2 and 4.6 months,respectively,with no statistically significant difference(χ^(2)=0.16,P=0.687).The mOS2 were 15.1 and 12.7 months,respectively,with no statistically significant difference(χ^(2)=0.01,P=0.930).The mPFS2 of patients in the second-line anti-angiogenic-treated and non-anti-angiogenic-treated groups were 4.5 and 6.0 months,respectively,with no statistically significant difference(χ^(2)=0.41,P=0.525),the mOS2 were 14.7 and 16.8 months,respectively,with no statistically significant difference(χ^(2)=0.01,P=0.943).Conclusions After progression of first-line ICIs therapy in patients with driver gene-negative advanced NSCLC,first-line ICIs-responsive patients have significantly longer OS after second-line treatment compared with ICIs-resistant patients.The efficacy of second-line therapy in patients after progression of first-line ICIs therapy does not show significant differences due to the type of treatment strategies.
