OBJECTIVE: To investigate the correlations of Homocysteine (Hcy), vascular endothelial growth factor (VEGF), and serum gastrin 17 (G17) with gastric cancer and precancerous lesions.
PATIENTS AND METHODS: A total of 56 patients with gastric cancer (gastric cancer group) and 53 patients with precancerous lesions (precancerous lesion group) admitted to Heze Municipal Hospital from January 2017 to October 2018 were selected, and 50 healthy subjects undergoing the physical examination in the same period were selected as control group. The levels of serum Hcy, VEGF, and G17 in the three groups were compared, and the relations of each index with clinicopathological characteristics of gastric cancer were analyzed.
RESULTS: The levels of serum Hcy, VEGF-A, VEGF-C, VEGF-D, and G17 in gastric cancer group and precancerous lesion group were higher than in control group, and those in gastric cancer group were higher than in precancerous lesion group (p<0.05). Besides, the high expression levels of serum Hcy, VEGF, and G17 had evident correlations with the tumor-node-metastasis (TNM) stage, Lauren type, infiltration depth, and lymph node metastasis of gastric cancer (p<0.05).
CONCLUSIONS: Hcy, VEGF, and G17 can exhibit different levels of expressions in precancerous lesions. They are also highly expressed in gastric cancer. Besides, they are involved in the occurrence and development of gastric cancer and can be regarded as crucial indexes with clinical significance for the differential diagnosis of gastric cancer and precancerous lesions in the early stage.
