Description
To evaluate the usefulness of two new imaging modalities in the clinical staging of prostate cancer the following study was done. Twelve patients with biopsy-proved carcinoma of the prostate were evaluated preoperatively with magnetic resonance imaging (MRI) of the pelvis and transrectal ultrasound of the prostate. The main parameters evaluated were the ability of these two modalities to accurately predict capsular penetration and seminal vesicle involvement in these 12 patients: 10 went on to pelvic lymph node dissections, and 8 had radical retropubic prostatectomies. Thus the preoperative studies could be compared to the pathologic results. Based on our results we believe transrectal ultrasonography is more accurate in the assessment of seminal vesicle involvement and comparable to MRI in determining capsular penetration. Because of the lower cost of ultrasound we believe it to be both an economical and accurate way to preoperatively stage prostate carcinoma.
