Moreover, in the analysis of the clinical data of these 50 patients, we found that TNM staging, lymph node metastasis, and CNN1 and VEGF expressions were all prognostic risk factors, which also indicates that the high expressions of CNN1 and VEGF may promote the metastasis and progression of tumor cells. The gene discussed is VEGFA; the disease is metastatic malignant neoplasm in the lymph nodes.
