Univariate analysis (Table 2) showed that NDRG1 expression (hazard ratio (HR) = 2.1, p = 0.0150), tumor grade (HR = 2.4, p = 0.0463), disease stage (HR = 4.6, p = 0.0011), ER status (HR = 0.4, p = 0.0098), and adjuvant radiation therapy (HR = 0.5, p = 0.0434) were associated with OS. This evidence concerns the gene NDRG1 and neoplasm.
