First we investigated whether expression levels of the SMARCA4 and SMARCA2 genes were associated to specific clinicopathological factors such as gender, age, tumor stage (T1 to T4 and stage I to IV), lymph node metastasis (N), distant metastasis (M), and differentiation (histological grade G1 to G4), obtained from TCGA. The gene discussed is SMARCA2; the disease is metastatic malignant neoplasm in the lymph nodes.
