Abstract
Conclusions Isolated clinical local recurrence is rare during long-term followup of men with Gleason score 7 disease and positive surgical margins at radical prostatectomy. Radiation therapy given at prostate specific antigen elevation poorly controlled the disease. Because patients with biochemical failure rarely had local recurrence at long-term followup, they most likely harbored subclinical distant metastasis. These data suggest that immediate adjuvant radiation therapy will not have a major impact on outcome because most men with Gleason score 7 disease and positive surgical margins in whom treatment fails most likely had distant metastasis at surgery. To improve the outcome in cases of Gleason score 7 disease and positive surgical margins a systemic approach to adjuvant therapy is necessary.
