Study Title

A Phase II Study to Evaluate the Safety and Efficacy of Prostatic Artery Embolization in Patients with Localized Prostate Carcinoma and Obstructive Lower Urinary Tract Symptoms


This is a Phase II prospective clinical trial in which patients with prostate carcinoma and obstructive lower urinary tract symptoms electing for radiation therapy will undergo Prostatic Artery Embolization (PAE) prior to treatment.


Primary Objective: To assess the clinical efficacy of PAE on LUTS Secondary Objectives: (i) To assess prostate volume reduction after PAE. (ii) To assess acute GU toxicity after PAE Correlative Objectives: (i) To assess for clinical or imaging signs of disease progression after PAE before definitive radiotherapy (ii) To assess effects of PAE on treatment planning



Transarterial Chemoembolization (TACE)
