GNPNAT1 and neoplasm: Correlation analysis displayed that GNPNAT1 was clearly correlated with gender (P = 0.00042), clinical stage (stage II vs. stage I, P = 0.0067; stage III vs. stage I, P = 1.8e-05; stage IV vs. stage I, P > 0.05), tumor size (T2 vs. T1, P = 3.3e-05; T3 vs. T1, P = 0.018; T4 vs. T1, P = 0.0064), lymph node metastasis (P = 2.9e-5) and patients’ status at the end of follow-up (P = 0.023) (Figures 3B–F).
