YAP1 expression was associated with Borrman's types (P = 0.041), WHO's histological types (P = 0.016), lymph node metastasis (P < 0.001), distant metastasis (P < 0.001), and TNM staging (P < 0.001), but was not associated with age, gender, Lauren's types, depth of invasion, and P62 expression (all P > 0.05) (Table 1). The gene discussed is YAP1; the disease is metastatic malignant neoplasm in the lymph nodes.
