However, in some tumors, KCC2 has the opposite predictive prognostic implications, such as UCEC (HR = 1.91, p = 0.0018), KIRC (HR = 1.89, p < 0.001), LIHC (HR = 1.66, p = 0.0036), gastric cancer (HR = 1.74, p < 0.001, n = 875, GEO), and lung cancer (HR = 1.16, p = 0.022, n = 1,925, GEO). This evidence concerns the gene SLC12A5 and lung carcinoma.
