Are pelvic computed tomography, bone scan and pelvic lymphadenectomy necessary in the staging of prostatic cancer?
OBJECTIVE: To investigate the effectiveness and economy of pelvic computed tomography (CT), bone scan and pelvic lymphadenectomy as staging modalities in patients undergoing radical prostatectomy. The use of prostate specific antigen (PSA) and Gleason’s score as adjuncts to predict extracapsular disease were also evaluated and their economic implications examined. PATIENTS AND METHODS: Between January 1990 and June 1993, 861 men were newly diagnosed with prostate cancer, of whom 409 underwent surgery. All patients underwent pelvic CT scans and PSA analysis. Patients undergoing surgery had pre-operative bone scans and Gleason’s scoring of their pathological tissue. RESULTS: Only 13 (1.5%) of 861 men had positive pelvic CT scans. Of the 409 patients who underwent surgery, all had negative pelvic CT and bone scans, and all underwent a modified pelvic lymphadenectomy; 192 (47%) had extracapsular disease. Only 15 (3.7%) patients who underwent surgery were found to have positive nodes. CONCL
