abstract
OBJECTIVE: • To evaluate feasibility, safety and oncological efficacy of salvage laparoscopic radical prostatectomy for pathology-proven biochemical recurrence after primary radiation therapy or cryotherapy for prostate cancer. MATERIALS AND METHODS: • This retrospective pilot study examined 15 patients from 2004 to 2010 with biochemical recurrence after external beam radiation therapy (N= 8), brachytherapy (N= 6) or cryotherapy (N= 1). • Patients were treated with salvage laparoscopic radical prostatectomy (11 conventional, four robotic-assisted) with bilateral pelvic dissection. RESULTS: • Median duration of surgery was 235 min. None of the following occurred: conversion to open surgery, transfusion, urethrovesical stenosis or perioperative or postoperative mortality. One patient presented with a rectal injury, repaired using uninterrupted sutures and a colostomy. One patient had anastomotic leak treated with prolonged Foley catheterization. • Pathological stage was pT2a in three, pT2b in three, pT3a in four, pT3b in three and pT4 in two patients; two patients had nodal metastasis. Within an 8-month median follow-up, 11 patients were disease-free and three had persistent postoperative prostate-specific antigen (PSA) elevation; the remaining patient experienced PSA recurrence after 21 months. • Seven patients achieved continence (no pads) by 8.4 months (median), one patient manifested severe incontinence corrected by implanting an artificial sphincter, and seven patients with a 12.6-month mean follow-up continued to need one or two pads per day. • Erectile dysfunction was present in five patients before surgery and in 14 patients after surgery. CONCLUSION: • Salvage laparoscopic radical prostatectomy seems to offer a safe therapeutic alternative for patients failing primary radiation or cryotherapy. However, larger studies with longer-term data are required.
