Introduction
Despite no consensus on the optimal management of recurrent prostate cancer after primary radiation or HIFU therapy, salvage prostatectomy (sRP) is reserved for only 3% of patients because of technical challenges and frequent post-operative complications. We assessed outcomes after sRP in a series of patients with localized PCa and that had received radiation therapy or HIFU as a first-line treatment.
Materials and methods
Data from nine French referral centers on patients treated with sRP between 2005 and 2017 were collected. Pre- and post-operative data, including oncological and functional outcomes after first treatment and sRP, were analyzed to determine the predictors for biochemical recurrence (BCR) and cancer-specific survival (CSS) after sRP.
Results
First-line treatments were external beam-radiation therapy (EBRT) for 30 (55%), brachytherapy (BT) for 10 (18%), and high-intensity focused ultrasound (HIFU) for 15 (27%). Median (IQR) PSA at diagnosis was 6.4 (4.9–9.5) ng/mL, median PSA at nadir was 1.9 (0.7–3.0) ng/mL, and median (IQR) to first BCR was 13 (6–20) months. Of the 55 patients, 44 (80%) received robot-assisted salvage radical prostatectomy and 11 (20%) received salvage retropubic radical prostatectomy. Restoration of continence was achieved in 90% of preoperatively continent patients; 24% that had received nerve-sparing (NS) procedures were potent after surgery. Prolonged catheterization due to anastomotic leakage was the most common complication. Age, preoperative clinical stage, NS procedure, and a pathological Gleason score were predictors for BCR.
Conclusions
sRP was safe, feasible, and effective using either an open or robot-assisted approach, in experienced hands. Age, preoperative clinical stage, NS procedure, and pathological GS were linked with BCR after sRP.
