Furthermore, urological cancers, including kidney and bladder cancers, also exhibited a significant association between elevated Gal-9 expression and longer OS (pooled HR = 0.42, 95% CI = 0.29-0.63, p < 0.0001), with minimal heterogeneity detected (I2 = 0.00%, p = 0.84). The gene discussed is LGALS9; the disease is urinary bladder carcinoma.
