DIXDC1 and neoplasm: In the intestinal-type, but not in the diffuse-type, DIXDC1 positive expression was correlated with age (≥60 years, P = 0.018), size (≥5 cm, P = 0.036), tumor differentiation (P = 0.003), the depth of invasion (P < 0.001), the lymph node metastasis (P < 0.001) and the clinical stage (P = 0.003) (Table 2).
