In the total group of ovarian cancer (OC) patients’ plasma levels of VEGF (168.48 pg/ml) and tumor markers, HE4 (103.60 pmol/L) or CA125 (133.30 U/ml) were found to be statistically higher compared to the healthy subjects (39.31 pg/ml; 44.15 pmol/L; 9.94 U/ml) (p < 0.001; respectively) (Table 2). This evidence concerns the gene VEGFA and neoplasm.
