The rates of submucosal invasion (85.7% vs. 42.9%, p = 0.061; Figure 4B) and lymph node metastasis (28.6% vs. 7.1%, p = 0.186; Figure 4D) were higher in patients with a high level of MUC1 expression than in those without MUC1 expression, although there was no statistical significance. The gene discussed is MUC1; the disease is metastatic malignant neoplasm in the lymph nodes.
