DDX39A and neoplasm: Pearson's Chi square test showed a positive correlation of high DDX39 expression with tumor size (p=0.007), TNM stage (p=0.011) and metastasis (p=0.001) (Table 2), while higher DDX39 expression, larger tumor size, more advanced TNM stage, more tumor emboli and metastases were predictive factors for PFS (Table 2).
