[Serum levels analysis of TGF-Beta and VEGF in patients with cancer anorexia-cachexia syndrome in lung cancer].
The pathogenesis of cancer anorexia-cachexia syndrome (CACS) is very complicated. In development of this syndrome play a role: metabolism of glucose, tumor necrosis factor (TNF), interleukin 1, interleukin 6, interferon a, interferon y, the oncological treatment and many other factors. Vascular endothelial growth factor (VEGF) is the most important proangiogenic factor. It promotes new vessels development, enhances vascular permeability and recruits monocytes. Many factors play a role in regulation of VEGF level. One of the most important is transforming growth factor beta (TGF-beta). Vascular endothelial growth factor and TGF-beta play a role in inflammation reaction too. The aim of this study was the evaluation of correlation between VEGF and TGF-beta in CACS in lung cancer.


METHODS
We measured the serum level of VEGF and TGF-beta in 40 patients with lung cancer (20 with and 20 without CACS) and in control group. The serum level was measured by ELISA method.


RESULTS
The correlation between VEGF and TGF-beta was not statistically significant in patients with CACS (p = 0.67), but the statistical significance was in patients without CACS (p = 0.006) and in control group (p = 0.035).


CONCLUSIONS
Results suggest, that VEGF regulation in CACS may be more complicated.
