Sixty consecutive patients were staged clinically by digital rectal examination, acid phosphatase and bone scan prior to radical retropubic prostatectomy and pelvic lymphadenectomy. Twenty-one patients also had magnetic resonance imaging (MRI) and computerized tomography (CT) of the pelvic. The surgical specimens were step-sectioned for pathologic staging. Understaging was documented in 0% of A2 patients, 27% of B1 patients and 67% of B2 patients. Capsular invasion was found in 12% of B1 and 52% of B2 patients, while seminal vesicle extension was documented in 18% of B1 and 52% of B2 patients. Lymph node metastases occurred in 3% of B1 and 29% of B2 patients. Clinical staging error was related to tumor size, tumor grade and history of prior TURP or radiotherapy. Neither CT scan nor MRI improved the accuracy of the digital rectal examination. |
