Resumen

Background: Although immune checkpoint inhibitor (ICI) monotherapy remains the standard of second-line treatment for patients with advanced non-small cell lung cancer (NSCLC) , the objective response rate (ORR) is low. There is an urgent need to increase the response population of second-line immunotherapy, and ICI combination therapy may be a possible option. However, the evidence is insufficient. Methods: We retrospectively collected the medical records of patients who received ICI monotherapy or ICI combination therapy as a second-line or later treatment option. We further analysed baseline clinical characteristics, evaluated treatment efficacy, assessed treatment-related adverse events (AEs) and followed up survival. The outcome variables assessed in the study were ORR, disease control rate (DCR), progression-free survival (PFS), overall survival (OS) and AEs. Results: A total of 145 patients were ultimately enrolled in this study, including the ICI monotherapy group (n=63) and ICI combination therapy group (n=82). The ICI combination therapy group was further divided into the ICI/chemotherapy group (n=57) and ICI/anti-angiogenic therapy group (n=25). The baseline was comparable among the three subgroups. The ICI combination therapy groups showed a higher ORR (29.3% vs. 11.1%, P=0.008) and DCR (85.4% vs. 61.9%, P=0.001) and a longer PFS (6.77 vs. 3.47 months, P<0.001) and OS (18.60 vs. 8.47 months, P<0.001) than the ICI monotherapy group. The ICI/chemotherapy group showed a significantly higher ORR (31.6% vs. 11.1%, P=0.006) and DCR (84.2% vs. 61.9%, P=0.006) and a longer PFS (6.37 vs. 3.47 months, P<0.001) and OS (18.60 vs. 8.47 months, P<0.001) than the ICI monotherapy group. The ICI/anti-angiogenic therapy group showed a significantly higher DCR (88.0% vs. 61.9%, P=0.021) and a longer PFS (8.17 vs. 3.47 months, P<0.001) and OS (19.20 vs. 8.47 months, P=0.005) than the ICI monotherapy group. Neither of the combined ICI therapy groups showed a significant increase in the incidence of AEs compared to the ICI monotherapy group. Conclusions: ICI combined with chemotherapy or anti-angiogenic therapy as second-line or later treatment demonstrated superiority over ICI monotherapy in advanced NSCLC patients without prior immunotherapy. These results provide a potentially superior treatment strategy and require verification in prospective clinical trials. © 2022 AME Publishing Company. All rights reserved.
