DHX37 and lung cancer: Two cohorts (GSE31210 and GSE11117) comprising 204 samples and 41 samples, respectively, of lung cancer revealed that upregulated expression of DHX37 was related to poorer final outcome (RFS (relapse-free survival) HR (hazard ratio) = 2.83, 95%CI (confidence interval) = 1.05 to 7.66, Cox P = 0.04; OS HR = 2.02, 95%CI = 1.07 − 3.82, Cox P = 0.03) (Figures 2(a) and (b)).
