In addition, low CADM4 expression (p = 0.023), advanced T category (p < 0.001), lymph node metastasis (p = 0.001), high AJCC stage (p < 0.001), lymphovascular invasion (p < 0.001), and perineural invasion (p = 0.001) were predictors of short RFS. The gene discussed is CADM4; the disease is metastatic malignant neoplasm in the lymph nodes.
