Abstract:
Objective To investigate the serum levels change of vascular endothelial growth factor (VEGF) during operation of non-small-cell lung cancer (NSCLC). Methods 120 cases of NSCLC patient diagnosed by pathology as well as with operation indication were selected as the experimental group. The patients selected were required without any chemotherapy or radiotherapy before operation, besides that, they should have good compliance and free will to be examined. During the process of experiment, 60 cases concluded as healthy in the physical examination were chosen as control group. The correlative information of the experimental group were collected including periphery blood specimen collected in 3 days before the operation, and of the 1st day, 7th day and 30th day after the operation while the periphery blood specimen of control group were collected. The serum levels of VEGF were detected by adopting enzyme linked immunosorbent assay (ELISA) method. Results The serum levels of VEGF in NSCLC patients before operation, of the first postoperative day, of the seventh postoperative day and of the thirtieth postoperative day were significantly higher than that in healthy people (P＜0.01), respectively (279.14±44.89)μg/L, (282.70±42.74) μg/L, (353.79±44.55) μg/L, (178.40±43.43) μg/L and (91.40±16.55) μg/L. The serum levels of VEGF in NSCLC patients showed positive correlation with the stages (P＜0.01). Conclusion The serum levels of VEGF in NSCLC patients scale up. At the same time it shows positive correlation with the stages of the primary tumor. The serum levels of VEGF in NSCLC patients scales up by degrees in one week after the operation, and drop one month later.
