High expression of STAT6 was significantly linked with the shortened OS in GBMLGG [HR = 1.99 (1.68, 2.37), p = 4.8e-15], LGG [HR = 1.97 (1.53, 2.52), p = 1.2e-7], UVM [HR = 2.83 (1.34, 5.97), p = 5.5e-3], and LAML [HR = 1.39 (1.19, 1.63), p = 3.2e-5], while lower STAT6 expression was significantly associated with lower OS rates in SARC [HR = 0.67 (0.54, 0.84), p = 5.3e-4] and BLCA [HR = 0.83 (0.70, 0.98), p = 0.03) (Figure 3G). This evidence concerns the gene STAT6 and bladder transitional cell carcinoma.
