Enriched TANs correlated with poor prognosis in patients with lung adenocarcinoma (LUAD). A, Analysis the association between different tumor-infiltrated immune cells and overall survivals in 2872 LUAD patients from eighteen different LUAD datasets. The level of neutrophils in each tumor sample was determined by CIBERSORT assay. B, Kaplan-Meier overall survival curve was shown according to high and low neutrophils distribution in 2872 LUAD patients. C, Neutrophils quantification in LUAD patients of different pathological stages. D, the clinical characteristics of the patients. E, immunohistochemistry of CD66b in tumor tissues derived from M0 (n = 18) and M1 (n = 18) lung patients. The scale bar was 50 μm.
