Numerous preclinical and clinical studies have demonstrated a role for angiogenesis in the growth and progression of breast cancer. Elevated vascular endothelial growth factor (VEGF) levels have been demonstrated in association with poor outcomes, and thus, this finding is an attractive target for therapeutic intervention.

When one considers the frequency with which practicing oncologists encounter situations and issues involving venous thrombosis in their patients, it is remarkable how little attention has been paid to this problem in the oncology literature or standard textbooks of oncologic theory and practice. Although the topic of hypercoagulability in cancer patients has been the subject of several excellent articles,[1,2] these reviews, while exhaustive with respect to pathophysiology, provide relatively little information of practical use to the oncologist.
