SNHG6 and cancer: The collective results showed that positive expression of SNHG6 appeared to be significantly correlated with poor OS (HR = 2.20, 95% CI = 1.76–2.75, P < 0.001) and RFS (HR = 3.10, 95% CI = 1.90–5.07, P < 0.001) in patients with human cancers, while no connection was identified between SNHG6 expression and PFS (HR = 2.11, 95% CI = 0.82–5.39, P = 0.120).
