Title: Expression level and clinical significance of vascular endothelial growth factor and CD44v6 in the diagnosis and treatment of small cell lung cancer
Abstract: Objective
To analyze the expression level of CD44v6 in small cell lung cancer and the concentration of vascular endothelial growth factor(VEGF) in serum, to explore the clinical significance of them in small cell lung cancer.
Methods
The expression level of CD44v6 was detected by immunohistochemical methods in 80 cases of small cell lung cancer as patients group, who were treat in People's Hospital of Jiangyin from January 2014 to January 2016.Another 80 cases of healthy subjects as control group.Used ELISA method to detect the concentration of VEGF of the two groups of patients in the blood.Analyzed the relationship between VEGF, CD44v6 with the survival time of patients.
Results
The CD44v6 expression in small cell lung cancer was positive in 6 cases, the total positive expression rate was 7.5%.The serum levels of VEGF in patients group((490.9±342.7) ng/L) was significantly different from that in the control group((180.8±67.5) ng/L), and the difference was statistically significant(P=0.024). There was no correlation between the survival time and the expression of CD44v6 in small cell lung cancer(P=0.723). The survival time of small cell lung cancer was negatively correlated with the concentration of VEGF in serum.
Conclusion
There is a significant correlation between serum VEGF concentration and survival time in patients with small cell lung cancer, which is one of the prognostic factors in patients with small cell lung cancer.
