BACKGROUND The purpose of the current study was to determine vascular endothelial growth factor (VEGF) concentrations in cyst fluid from malignant, borderline, and benign ovarian tumors, and to correlate these data with preoperative serum VEGF concentrations and clinicopathologic characteristics. METHODS One hundred seven ovarian cysts were removed and punctured for cyst fluid collection. Histologic diagnosis revealed 25 malignant, 12 borderline, and 70 benign ovarian tumors. The VEGF concentrations of all the cyst fluid specimens as well as in 37 preoperatively collected serum samples were determined by making use of a sandwich type double determinant enzyme linked immunoadsorbent assay based on a combination of 4 polyclonal antibodies. RESULTS Statistically significantly higher VEGF concentrations were found in cyst fluid from malignant (median, 21.5 μg/L) compared with borderline (median, 3.2 μg/L; P = 0.01) or benign tumors (median, 1.3 μg/L; P < 0.0001). Preoperative serum VEGF concentrations were significantly higher in patients with malignant (median, 0.63 μg/L; range, 0.016–17.7 μg/L) compared with nonmalignant tumors (median, 0.28 μg/L; range, 0.016–0.89 μg/L; P = 0.008). A significant correlation of preoperative serum VEGF was found with VEGF cyst fluid concentrations (r = 0.38; P = 0.02). Significantly higher VEGF cyst fluid concentrations were found in serous malignant (median, 31.9 μg/L) compared with mucinous malignant tumors (median, 4.7 μg/L; P = 0.004). Not significant, though higher median VEGF cyst fluid concentrations were found in advanced International Federation of Gynecology and Obstetrics (FIGO) Stage II, III, and IV, histologic Grade 2 and 3, patients with residual tumor greater than 2 cm, with malignant cells in ascites or peritoneal washings, or with recurrent disease, as compared with FIGO Stage I, histologic grade 1, patients with less than or equal to 2‐cm residual tumor, without malignant cells in ascites/peritoneal washings, or without recurrent disease, respectively. CONCLUSIONS It has become clear from the increased study sample that ovarian tumors of different histologic etiology vary in VEGF cyst fluid concentrations, with the highest VEGF cyst fluid concentrations in malignant tumors. The prognostic significance of VEGF cyst fluid concentrations in advanced FIGO stage seems to be of limited value but may be important in the selection of high risk FIGO Stage I and borderline types. Data from this study indicate a possible role for VEGF as a serum tumor marker. Cancer 2001;91:371–7. © 2001 American Cancer Society.
