Similarly for patients with lymph node metastasis we identified four proteins, namely IL1α, XIAP, STX2, and SHKBP1, whereas for patients with liver metastasis we identified IGF1, IL1α, IGFBP2, MAML3, and SHKBP1 as significant. This evidence concerns the gene IL1A and metastatic malignant neoplasm in the lymph nodes.
