[Pelvic exenteration in patients with locally advanced, symptomatic castration-resistant prostate cancer]

The retrospective evaluation of clinical outcomes after palliative pelvic exenteration (PPE) in patients with subvesical and supravesical complications due to symptomatic locally advanced castration-resistant prostate cancer (CRPC).

In all, 84 patients with locally advanced and symptomatic CRPC underwent radical cystoprostatectomy (n = 71, 83.3%) or anterior and posterior exenteration (n = 13, 16.7%). Local staging was done via pelvic MRI (magnetic resonance imaging), cystoscopy, and rectoscopy. Systemic staging was performed by computed tomography of the thorax, abdomen pelvis, and skeletal scintigraphy. Perioperative complications were evaluated using the Clavien-Dindo classification. The primary study objective was symptom-free survival defined as absence of lower or upper urinary tract symptoms and absence of endoluminal or percutaneous intervention.

After a median follow-up of 43.5 (3-139) months, symptom-free survival at 1 and 3 years was 95.2% and 86.7%, respectively. In all, 86.7% of patients remained symptom-free for their remaining lifetime with respect to local symptoms. Overall survival at 1 and 3 years was 92.9% and 54.7%, respectively. Clavien-Dindo grade 2, 3, and 4 complications occurred in 19 (22.6%), 7 (8.3%), and 3 (3.6%) patients, respectively.

With adequate patient selection, PPE is possible with a low complication rate and results in significant symptom relief in the lower or upper genitourinary tract in about 90% of patients, of whom more than 80% remain symptom-free for the remainder of their lives. Prerequisites for favorable surgical outcomes are patient selection, an interdisciplinary approach, and appropriate surgical expertise.
