ABSTRACT

Preceding. The prostate cancer is the second one tumor common in the man. It is esteemed 198,000 cases diagnosed annually and 80,000 patients are submitted to radical prostatectomy in USA. Approximately 30% has cancer in the margin of resection. Our objective is to know the relation of the percentage positive fragments in the biopsies of prostate with the margins surgical in patients submitted to radical prostatectomy. Material and methods. Study retrospective, open, cross. Period of July 1991 to July 2004. Age is analyzed, antigen prostates, Gleason, positive biopsies, surgical margins, tumor volume. Statistical descriptive, “t” Student and analysis bivariate. Results. Were included 65 patient, with negative margin 33 and positive 32. Age average 66.9 and 65.5 years respectively. Antigen prostates average of patients with positive margin 15.1 ng/mL (p = 0.033) and tumor volume of 45% (p = 0.012). 50% associate to greater risk of positive margins (p = 0.06). Conclusions. Patient with but of the 50% of positive biopsies have high risk of positive margins, also are to a greater volume tumor.
