摘要
Purpose: Digital rectal examination, preoperative serum prostate specific antigen (PSA) concentration and results of 6 ultrasound guided systematic sextant biopsies in 257 consecutive patients with clinical stages T2 and T1c prostatic carcinoma were evaluated for their use in predicting pathological stage and tumor recurrence. Materials and Methods: Each of the 257 consecutive specimens was examined using the 3 mm. step section technique. Results of preoperative digital rectal examination, PSA and 6 systematic sextant biopsies were correlated with pathological stage, margin status and postoperative PSA during a mean followup of 2 years. Patients were considered to have disease progression based on an elevated PSA level by a supersensitive assay. Results: Digital rectal examination could not predict pathological stage and tumor recurrence. Preoperative PSA concentration, number of positive biopsies and tumor grade in the biopsy specimens correlated well with pathological stage. The best predictor of tumor recurrence was the biopsy result. However, a precise prediction of outcome (87% probability of being PSA negative versus 0%) was possible only in a third of the patients if the biopsy results were used. Use of preoperative PSA concentration did not improve this probability. Conclusions: Preoperative PSA concentration and/or biopsy results correlate significantly with pathological stage and margin status. Precise prediction of tumor recurrence is possible in only approximately a third of the patients with clinical stage T2 prostatic carcinoma.
