The expression of vascular endothelial growth factor is associated with the risk of cancer progression after radical prostatectomy

OBJECTIVE: To analyse the prognostic value of vascular endothelial growth factor (VEGF) in men with clinically localized prostate cancer. PATIENTS AND METHODS: Paraffin wax-embedded sections from the radical prostatectomy (RP) specimens of 40 men operated for clinically localized prostate cancer were used to build tissue microarrays. Of these patients, 17 had cancer progression and bone metastases after RP (group 1), and 23 remained free-of-tumour recurrence after RP (group 2). VEGF-A expression was examined in the RP specimens using immunohistochemistry. RESULTS: The groups had similar tumour characteristics in terms of prostate-specific antigen level, Gleason score, and pathological stage. VEGF-A expression was significantly higher in group 1 than in group 2 (P = 0.046). In logistic regression analysis, VEGF-A expression was the most significant predictive factor of cancer progression after RP. CONCLUSION: VEGF-A expression in prostate cancer tissue is associated with the risk of cancer progression after RP. These results suggest that VEGF-A expression has a prognostic impact in clinically localized prostate cancer.
