| Popis: | Anti-PD-1 therapy has been the standard treatment for advanced NSCLC patients. Some patients show durable response, while there are cases that show rapid progression after initiation of ICI treatment, which leads to early death. Therefore, we need a clear biomarker that identifies for early death after initiation of ICI treatment. We reported that CRP is a predictive marker for the efficacy of nivolumab for advanced NSCLC. Among pro-inflammatory cytokines, IL 6 and IL-1β are reported as a poor prognostic factor of cancer patients, and TNFα and INF-γ are reported to be one of the predictors of ICI efficacy.The aim of this study is to investigate the relationship between serum pro-inflammatory cytokines levels and the efficacy of ICI treatment and early death after ICI treatment. Methods: We retrospectively reviewed the predictive factors of efficacy and early death (death within 3 months after initiation of treatment) in anti-PD-1 monotherapy in all cohort (N=307). Based on the results in all cohort, we investigated the relationship of proinflammatory cytokines (IL-1β, IL6, IL10, INFγ) level in serum before pre-anti PD-1 therapy by Luminex® system and the clinical outcome of anti-PD-1 treatment in cytokine cohort (N=67). Patients with advanced or postoperative recurrence NSCLC who received 1≤ dose of ICI from December 2015 to September 2018 in our institute were included. Results: Among 307 patients, 45 patients (14.6%) died within 3 months after the initiation of anti-PD-1 therapy in all cohort. The median PFS of ICI treatment was 3.1months (95%CI: 2.5-4.1). EGFR or ALK mutation, poor PS (2≤), PD-L1 negative, high CRP(1.0 mg/dl≤) were identified as predictive factors for shorter PFS using Cox proportional model. Poor PS, high lung immune prognostic index (2≤), low albumin ( Conclusions:This analysis demonstrated that serum high IL6 level at baseline associated with the early death after initiation anti-PD-1 treatment and shorter PFS in advanced NSCLC.
