ASSOCIATION WITH TUMOR RECURRENCE AT ONE YEAR AFTER PROSTATECTOMY. Background : Prostate cancer (PC) is the second cause of death by cancer in men in Chile. Its behavior is so variable that it is necessary to search reliable prognostic markers. Vascular Endothelial Growth Factor (VEGF) is one of the most powerful pro-angiogenic factors. There is no agreement on its validity as a diagnostic or prognostic factor. Aim : To search for VEFG in prostatic tissue. Material and Methods : This study was performed in prostatectomy tissue coming from 41 patients with PC and 39 patients with benign prostatic hyperplasia (BPH). Specimens were studied using immunohistochemical staining for VEGF. The percentage of stained glandular cells per patient was calculated and associated with pathological diagnosis in cancer patients. Results: PC biopsies had a mean of 82% of VEGF (+) stained cells, while BPH had only 1.6% (p Conclusions : These results would rule out VEGF as a prognostic factor in this series of patients. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Tabla normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0cm 5.4pt 0cm 5.4pt; mso-para-margin-top:0cm; mso-para-margin-right:0cm; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0cm; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;} |
