Moreover, the univariate analysis showed that differentiation (P = 0.036), tumor size (P = 0.016), lymph node metastasis (P < 0.001), TNM stage (P < 0.001), invasion into serous membrane (P = 0.016), and USP14 overexpression (P = 0.002) were correlated with DFS, respectively (Table 2). This evidence concerns the gene USP14 and neoplasm.
