AXL expression was also positively correlated with lymph-node metastasis, since patients with N1 cholangiocarcinoma (metastasis found in 1–3 axillary lymph nodes) had higher AXL expression than N0 patients (p = 0.0195, Figure 1a). The gene discussed is AXL; the disease is metastatic malignant neoplasm in the lymph nodes.
