VEGFA and metastatic malignant neoplasm in the lymph nodes: We performed a univariate analysis of the clinicopathological factors affecting prognosis using Cox regression models, which showed that the TNM staging (p = 0.009, HR = 2.867, 95% CI [1.299–6.324]), lymph node metastasis (p = 0.046, HR = 2.198, 95% CI [1.015–4.758]), a CNN1 expression level (p < 0.001, HR = 23.541, 95% CI [5.438–101.901]), and the VEGF expression level (p < 0.001, HR = 19.688, 95% CI [4.607–84.131]) were associated with a poorer prognosis (Table 3).
