Abstract
Purpose Angiogenesis is a critical process for cancer progression. We tested whether elevated circulating levels of the angiogenesis-related markers vascular endothelial growth factor (VEGF) and/or soluble vascular cell adhesion molecule-1 (sVCAM-1) are associated with prostate cancer diagnosis, stage, progression, and metastasis. Patients and Methods Plasma levels of VEGF and sVCAM-1 were measured on frozen, archival plasma obtained preoperatively from 215 consecutive patients who underwent radical prostatectomy for clinically localized disease, nine men with untreated prostate cancer metastatic to bones, and 40 healthy men without cancer. Results Plasma levels of both VEGF and sVCAM-1 were highest in patients with bone metastases (P < .001). VEGF levels were higher in patients with clinically localized disease than in healthy controls (P < .001). VEGF levels were elevated in patients with biopsy and final Gleason sum ≥ 7 (P = .036 and P = .020, respectively) and extraprostatic extension (P = .047). High...
