[The estimation of serum concentration of vascular endothelial growth factor in patients with non-small cell lung cancer].

UNLABELLED

Vascular endothelial growth factor (VEGF) is main angiogenic factor, which stimulates endothelial cells migration and proliferation. The extensive angiogenesis plays important role in tumor growth and metastasis.

AIM OF THE STUDY

Analysis of serum concentrations of vascular endothelial growth factor in patients with non-small cell lung cancer depending on clinicopathologic findings.

MATERIAL AND METHODS

The study group consisted of 50 patients with non-small cell lung cancer (16 females and 34 males) ranging in age from 47 - 80 years (mean age 63 +/- 8.2). Serum VEGF concentration was evaluated by ELISA.

RESULTS

VEGF concentrations in serum did not differ significantly between groups of patients with different T-, N- and M-factor. Patients with inoperable tumor (IIIB and IV) had significantly higher serum VEGF concentrations compared with resected tumor (I-IlIA) and locally advanced cancer (IIIA).

CONCLUSIONS

Serum VEGF may be a marker of tumor progression in non-small cell lung cancer.
