Univariate analysis indicated that ZFX expression, tumor differentiation and TNM stage were all prognostic factors for OS in stage II and III patients (p = 0.001, p = 0.019, and p = 0.005), while multivariate analysis confirmed that only ZFX expression and TNM stage were independent prognostic factors for OS in stage II and III patients (p = 0.007 and p = 0.034) (Table 2). The gene discussed is ZFX; the disease is neoplasm.
