In two lung cancer cohorts (GSE13213 and GSE4573), higher TMPRSS2 expression was associated to favorable outcomes (OS HR = 0.68, 95% CI = 0.51–0.89, Cox p = 0.006146; OS HR = 0.83, 95% CI = 0.70–0.0.99, Cox p = 0.042151) (Supplementary Table S1). This evidence concerns the gene TMPRSS2 and lung cancer.
