The expression of IRF1 may be associated with lymph node metastasis (P = .052); there were no significant correlations found between the expression of CD3D, CD3G, and CXCL9 and lymph node metastasis in the GSE40967 dataset (Fig. 5A, B). The gene discussed is CXCL9; the disease is metastatic malignant neoplasm in the lymph nodes.
