VEGF, HIF-1α, and Metabolic Indicators in Esophageal Squamous Cell Carcinoma

Abstract

Objective: To explore and analyze the expression and clinical significance of vascular endothelial growth factor (VEGF), hypoxia-inducible factor 1α (HIF-1α), and metabolic indicators in esophageal squamous cell carcinoma (ESCC). Methods: Sixty ESCC patients admitted to the hospital from October 2021 to October 2023 were selected as the ESCC group. Sixty normal healthy patients from the same period were chosen as the control group. Their serum samples and tissue samples were collected. Metabolic indicators of all study subjects were obtained based on the basic biochemical results upon admission. RT-PCR was utilized to detect the expression of VEGF and HIF-1α in ESCC tissues. Results: The expression of VEGF and HIF-1α in the ESCC T3+T4 group was significantly higher than that of the carcinoma in situ (Tis) group, T1+T2 group, and control group. Furthermore, the expression of HIF-1α was found to be related to the expression of VEGF, showing a significant correlation between the quantities. Significant differences in the levels of metabolic indicators were observed between the ESCC group and the control group (P < 0.05). Conclusion: Metabolic indicators are associated with the onset of ESCC in patients. Abnormal lipid metabolism plays a crucial role in the occurrence and development of tumors. The expression of VEGF and HIF-1α in ESCC tissues significantly correlates with the tumor stage, providing a new reference for the diagnosis and treatment of ESCC.
