In the comprehensive analysis of whole FOXP family mRNA expression, by D. M. Hu et al., the lower FOXP3 expression was correlated with a better prognosis of lung adenocarcinoma (LUAD) (HR = 1.37 and 95% CI 1.09–1.73) and with a better prognosis of NSCLC (HR = 1.25 and 95% CI 1.1–1.41) [27]. This evidence concerns the gene FOXP3 and lung adenocarcinoma.
