Based on our experience, bladder neck closure and continent vesicostomy represent a valuable therapeutic option in the management of recurrent anastomotic strictures following radical prostatectomy.
47 Background: Radical salvage prostatectomy (SRP) is one local treatment option with curative intent in patients failing radiation therapy (RT) for localized prostate cancer (PCA). We compared the surgical, histological and functional outcome of a large cohort of patients who underwent SRP for locally recurrent PCA following LDR – brachytherapy (BRT). Methods: 66 consecutive patients with locally recurrent PCA after BRT underwent retropubic SRP and pelvic lymphadenectomy. Preoperative PSA, PSA doubling time, PSA prior to initial RT, biopsy Gleason score, number of positive biopsies, cT stage, neoadjuvant androgen deprivation were correlated with pathohistological stage, complications and functional outcome by uni- and multivariate analysis. Results: Mean preop. PSA was 5.6 (2-13.5) ng/ml; mean preoperative biopsy Gleason score was y5.6 (4-9). 1 patient (1.5%) experienced a rectal lesion, mean blood loss was 430 (200-900) ml, none of the patients received blood transfusions. Pathohistology demonstrated organ confined prostate cancer pT2a-2c in 38 (57.5%) patients, stage pT3a and stage pT3b was identified in 14 (21.1%) patients and in 14 (21.1%) patients, respectively. Positive surgical margins were diagnosed in 9 (13.6%) patients and 12 (15.1%) patients harboured lymph node metastases. Functional outcome was good with a continence rate of 82%; the mean time until recovery of continence was 8.4 (6-14) months. After a mean follow-up of 22.5 (1-72) months, 28% of the patients experienced a PSA relapse defined as any PSA increase > 0.2 ng/ml validated by 2 consecutive measures. Conclusions: SRP can be performed safely and with a low morbidity in biopsy proven locally recurrent PCA following BRT. However, our data demonstrate an unfavourable histology with locally advanced disease in about 40% of the patients who all were diagnosed with low risk prostate cancer. These data question the quality of the selection process for patients being counselled for BRT and the data raise the possibility of both intrinsic radioresistance of prostate cancer or poorly performed BRT.
With radical tumour surgery an effective local symptom control can be achieved. This individual therapeutic concept should be discussed in highly selected patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
