Serum concentration of VEGF, sFLT-1, and CD105 in patients with endometrial carcinoma.

Abstract

e15564 Background: Preoperative evaluation of the risk for metastases in endometrial carcinoma is challenging. The aim of this study was to compare preoperative serum levels of angiogenetic markers VEGF, sFLT-1, and CD105 (endoglin) in predicting a metastasized disease. Methods: Preoperative sera from 100 consecutive patients diagnosed for endometrial carcinoma were collected. The serum concentrations of VEGF, sFLT-1, and CD105 were assessed by enzyme-linked immunosorbent assay (ELISA). The results were correlated to the presence of metastases, presence of deep (≥50%) myometrial invasion and histologic grade of the tumor. Cases with other than endometrioid histology were excluded from the study. Results: Eleven patients had a metastasized disease (≥Stage IIIA, FIGO 2009 classification). The serum concentration of VEGF was higher in the group with metastases (median [range] 394 pg/mL [31-1524 pg/mL] vs. 801 pg/mL [631-1183 pg/mL], p=0.001). The concentrations of sFLT-1 and CD105 did not show statistical difference between the two groups. In the multivariable analysis, the concentration of VEGF was the sole independent factor for the presence of metastases (OR 1.003, 95% CI 1.000-1.005, p=0.019). Conclusions: Preoperative serum VEGF concentration correlates with the presence of metastases in endometrioid endometrial carcinoma.
