To better identify factors affecting prostate-specific antigen (PSA) level elevation after radical prostatectomy alone in men with clinical Stage T1-2 prostate cancer, we have reviewed our experience in the PSA era with 337 cases. The identification of these factors permits better understanding of the impact of case selection on treatment outcome in prostate cancer. ⋯ Pretreatment PSA is the most potent clinical factor independently predicting biochemical relapse. The great range in the relapse-free survival rates predicted by preoperative PSA levels demonstrates the importance of pretreatment PSA levels in case selection. Gleason score, extracapsular extension, and surgical margin involvement are also independent predictors of biochemical relapse. Achieving negative margins, even in relatively advanced disease, provides excellent long-term local control.
