Multivariate analysis showed that all three factors were independently predictive of OS, with a hazard ratio of 2.037 for age (95% CI: 1.137–3.651, P=0.017), 1.840 for tumor necrosis (95% CI: 1.104–3.068, P=0.019), and 2.002 for OGT expression (95% CI: 1.183–3.391, P=0.010) (Table 3). The gene discussed is OGT; the disease is neoplasm.
