Role of computed tomography in the evaluation and management of carcinoma of the prostate.

Between January 1978 to March 1980, 25 patients with biopsy-proven prostate carcinoma were evaluated by computerized tomography (CT). CT differed from clinical stage in 7 of 25 patients (28%). In 6 of the 7 patients, change in stage resulted because of demonstration of extracapsular extension and/or pelvic lymph node involvement. Twelve of the 25 patients (48%) underwent surgery with histological confirmation of CT findings. Ct identified nodal involvement accurately in 10 of 12 patients (83%). We recommend use of CT for initial staging, treatment planning and assessment of response in the management of prostate cancer.
