MT2A and neoplasm: Univariate analysis indicated that some factors including decreased MT2A expression (P < 0.001), TNM stage (P < 0.01), tumor depth (P < 0.05), lymph node status (P < 0.05), distant metastasis (P < 0.001) and degree of differentiation (P = 0.011) were correlated with poor survival (Table 1).
