1 Serum VEGF in patients of NSCLC on preoperative day, postoperative 1 day and 7 day were (842.06±527.24)pg/mL, (1 119.28±609.62)pg/mL, (1 574.09±873.38)pg/mL, respectively (P < 0.001);2Platelet counts in patients of NSCLC on preoperative day, postoperative 1 day and 7 day were (230.42±82.56×109/L, (196.47±81.48)×109/L, (237.90±86.94)×109/L; the value on postoperative 1 day was the lowest (P < 0.001);3On postoperative 7 day, serum VEGF in the group of lower than the mean and higher than the mean were respectively (1 398.81±734.00)pg/mL and (1 842.86±1 006.63)pg/mL (P=0.043). This evidence concerns the gene VEGFA and non-small cell lung carcinoma.
