Radical laparoscopic salvage prostatectomy: medium-term functional and oncological results.

AIM

To analyze the surgical, functional, and oncological results of radical laparoscopic salvage prostatectomy in local postradiotherapy recurrence.

PATIENTS AND METHODS

Between May 2005 and April 2007, we treated nine patients with radical laparoscopic salvage prostatectomy. Five patients had received prior treatment with brachytherapy and the other four with external radiotherapy. The average age of the patients was 59.3 years (range 51-68). The average preoperative prostate-specific antigen was 9.1 ng/mL (range 2.6-30). The average follow-up period was 26.8 months (range 15-39).

RESULTS

The average duration of surgery was 170 minutes (from 120 to 240). There was no need to resort to open surgery or transfusions. There were no cases of rectal injuries. Four cases were pT2c, 1 pT3a, 3 pT3b, and 1 pT4a. The Gleason score was 7 in three cases, 8 in two cases, and 9 in another four. Two patients had nodal metastasis. Postoperative prostate-specific antigen was undetectable in seven of the nine patients. Two patients experienced biochemical recurrence 16 and 13 months after the surgery. After a minimum follow-up period of 15 months, they were free from recurrence. There were no cases of urethrovesical anastomotic stenosis. Three patients manifested severe incontinence (more than two diapers per day), which was corrected in two cases by implanting an artificial sphincter. The other six patients required 0 to 1 pads/day. Before the surgery, only one of the five potential patients maintained his erectile function.

CONCLUSIONS

Radical laparoscopic salvage prostatectomy is a complex technique that seems to allow attaining high and long-lasting rates of biochemical remission in patients with local postradiotherapy recurrence. Although there is less morbidity in our series in comparison with the anastomotic stenosis and rectal injuries rate published in radical retropubic salvage prostatectomy, more extensive comparative studies are required to confirm this fact.
