ConclusionsConclusions

• The current study supports the feasibility of incorporating paclitaxel into preoperative regimens for pts with EC

• The efficacy of this regimen compares favorably with our previously reported data

• VEGF serum levels are raised in the serum of EC pts, but preoperative CTRT has littleeffect on the angiogenic profile of tumor

• The current study supports the feasibility of incorporating paclitaxel into preoperative regimens for pts with EC

• The efficacy of this regimen compares favorably with our previously reported data

• VEGF serum levels are raised in the serum of EC pts, but preoperative CTRT has littleeffect on the angiogenic profile of tumor
