abstract
OBJECTIVE: To define the role of salvage prostatectomy in patients who have locally recurrent prostate cancer following pelvic lymph node dissection and 125I implantation. PATIENTS AND METHODS: Over 1000 patients underwent 125I implantation for localized prostate cancer at the Memorial Sloan Kettering Cancer Center between 1970 and 1986. Salvage radical prostatectomy was performed in a highly selected group of 10 patients with locally recurrent disease. RESULTS: Three of the 10 patients had organ-confined residual prostate cancer following salvage radical prostatectomy. The remaining seven patients had extra-prostatic disease including four patients with positive surgical margins. Two patients with organ-confined disease and one with extracapsular tumour had no evidence of locally recurrent or metastatic disease and continue to have undetectable prostate-specific antigen (PSA) levels at 50, 44, and 31 months following salvage radical prostatectomy. After a mean follow-up of 30 months, the remaining seven patients had a rising PSA level consistent with locally persistent and/or metastatic disease (median 5 ng/mL; range 1.0-144). This PSA elevation occurred within 20 months of salvage radical prostatectomy (median 6 months). Two of these patients developed clinically evident bone metastases. CONCLUSION: Salvage radical prostatectomy, although technically feasible in highly selected patients, should not be widely advocated as an effective treatment option for patients with locally recurrent prostate cancer after 125I implantation.
