Abstract :
[en] [en] BACKGROUND: Non-small cell lung cancer (NSCLC) remains a major therapeutic challenge. While PD-1/PD-L1 immunotherapies have improved outcomes, predictive biomarkers are limited. AXL, a receptor tyrosine kinase associated with poor prognosis, may impact treatment response. This study evaluates AXL expression and clinical outcomes in advanced NSCLC patients treated with immunotherapy or chemotherapy. METHODS: This retrospective study included 89 metastatic NSCLC patients treated at the University Hospital of Reims (2015-2023) with either anti-PD-1 therapy or chemotherapy. Clinical data and outcomes-progression-free survival (PFS) and overall survival (OS)-were analyzed. AXL expression was assessed by immunohistochemistry, and propensity score matching adjusted for prognostic variables. RESULTS: AXL-positive tumors were associated with shorter PFS (4.3 vs. 5.3 months, p = 0.044). Immunotherapy improved PFS (7.6 vs. 4.4 months, p = 0.006) and response rate (48 % vs. 22 %) compared to chemotherapy. However, AXL-positive patients derived less benefit from immunotherapy; IO-treated AXL-negative patients had significantly better PFS (p = 0.003) and OS (p = 0.018). Multivariate analysis identified AXL as an independent factor for poorer PFS (HR 4.15, p = 0.013) and OS (HR 5.634, p = 0.004). KRAS and STK11 mutations were more frequent in AXL-positive tumors. CONCLUSIONS: AXL expression is associated with reduced immunotherapy efficacy in NSCLC and may serve as a predictive biomarker and therapeutic target.
