Prostate artery embolization (PAE) is emerging as a safe and efficacious treatment which approaches benign prostatic obstruction (BPO) from a unique perspective. This brings with it distinct advantages and solutions, which we discuss along with cost, evidence, complications and disadvantages.

Abstract Backgrounds: Prostatic artery embolization (PAE) has been well studied as a clinically effective therapy for alleviating lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH). We demonstrate a proof of concept for PAE prior to definitive radiotherapy in patients with prostate cancer.Methods: From 12/2017 to 07/2019, 57 patients underwent PAE for LUTS and BPH. Nine of these patients had PAE for LUTS in the setting of localized prostate cancer prior to receiving radiation. Five of the nine patients received their entire radiotherapy course at our institution and had clinical follow up were included in the analysis. Median follow up was 18 months from the time of PAE. LUTS improvement quantified by IPSS was the primary endpoint and a two tail students T test was used to compare statistical significance. Side effects during radiation were quantified using the CTCAE scoring system. Pre- and post- PAE plans were compared in the five patients that by performing an isovolumetric expansion of the post PAE plan (treated plan) equivalent to the measured volume reduction after PAE. Patient 1 and 2 had prostate and seminal vesicle RT alone while patients 3-5 had prostate with elective nodal coverage. Mean doses to organs at risk were compared between the two plans.Results: The average IPSS score pre-PAE was 17.40 compared to post-PAE of 3.6 (p=0.02). The average IPSS score reduction after PAE was 13.8 (5-30). The average prostatic volume reduction after PAE was 23.14% (7.2% - 47.7%). There were no CTCAE grade 3 (severe) or higher during radiation treatment. Post-PAE plans in patient 1 and 2 had on average 16.7% and 39.8% decrease in mean dose across the bladder, rectum, and penile bulb compared to the pre-PAE plans. There were no appreciable differences in dosimetry in the patients 3-5 who had nodal coverage. There was no biochemical failure in any of the patients.Conclusion: We demonstrate a proof of concept that prostate artery embolization is useful as an adjunctive procedure to alleviate LUTS, achieve significant volume reduction prior to radiation therapy, and decrease radiation related toxicity in the treatment of prostate cancer.
