Background: Combined therapy with immune checkpoint inhibitors (ICIs) and microwave ablation (MWA) is known to improve outcome in non-small cell lung cancer (NSCLC). However, the mechanism underlying the synergistic effect of these two treatments is unknown. Tumor immune microenvironment is known to affect the efficacy of ICI. Therefore, in the present study, we evaluated changes in the levels of peripheral cytokines at 48 h and 1-month post-ablation in patients with NSCLC. Materials and Methods: A total of 44 patients with primary NSCLC were retrospectively enrolled. All patients underwent MWA of the primary tumors. Plasma samples were collected pre- and post-ablation to examine the levels of various cytokines, including interleukin (IL)-2, IL-4, IL-6, IL-10, IL-12, IL-17, tumor necrosis factor (TNF)-α, and interferon-gamma (IFN-γ). Results: Although the levels of the majority of cytokines remained within normal range, levels of IL-2 and IFN-γ were significantly decreased at 48 h post-ablation and increased at 1-month post-ablation. In the subgroup analyses, changes in IL-2 and IFN-γ levels were commonly identified. Moreover, the Eastern Cooperative Oncology Group status, sex, pathology type, tumor site, and tumor size were associated with cytokines' levels pre-ablation or post-ablation. Conclusion: MWA of NSCLC tumors influenced the plasma levels of cytokines IL-2 and IFN-γ.
