VEGFA and gastric cancer: Some studies (50–52) compared the expression level of VEGF in GC tissue and normal gastric mucosal tissue, and the results indicated that the expression level of VEGF in GC tissue was higher than that in normal gastric mucosal tissue and was related to pathological type, TNM system, and lymph node metastases (53), which suggests that VEGF may be a potential diagnosis and treatment indicator for the occurrence and development of GC.
