简要总结
The primary objective of this trial is to compare the 9-month effect on lower urinary tract symptoms (LUTS) of Prostatic Artery Embolization (PAE) using Embosphere® versus Standard Combined Therapy (alpha-blockers plus 5 alpha-reductase inhibitors) in patients with symptomatic BPH who failed after a first line medical treatment with alpha-blockers.
The secondary objectives of this study are to:
- Estimate the impact of the 2 strategies on benign prostatic hyperplasia specific Health Status (i.e. urinary and sexual signs and symptoms) at 3, 9, 18, and 24 months, as well as the side effects of the 2 strategies;
- Report the safety of PAE;
- Evaluate patient's adherence to medical treatment;
- Analyse the costs of each strategy and report the incremental efficiency (incremental cost utility ratio) of prostatic artery embolization compared to medical treatment.
详细描述
Benign Prostatic Hyperplasia (BPH) is the primary cause of lower urinary tract symptoms (LUTS) and affects > 50% of men >60 years. Moderate to severe symptoms prevalence is around 14% in France, and the proportion of men with moderate to severe symptoms doubles with each decade of age. The first-line treatment of bothersome BPH-related LUTS is medical therapy as recommended by French and European guidelines. 5α reductase inhibitors (5-ARI) can be combined with alpha-blockers and allow reduction of the size of the prostate and LUTS improvement. The severity of symptoms is usually assessed using the International prostate symptom score (IPSS) which is the standard questionnaire for the objective assessment of LUTS.
Recently, Prostatic Artery Embolization (PAE) has been proposed to treat symptomatic BPH with good safety and efficacy in single-centre studies (12-point IPSS reduction at 3 months maintained up to one year. In a randomized trial comparing PAE versus transurethral resection of prostate (TURP), Gao reported a 16-point IPSS reduction at 6 months, and an increase in the maximum urinary flow rate (Qmax) comprised between 12 ml/s and 24 ml/s at 6 months and up to 21 ml/s at 2 years. The complication rate is low (a few cases of bladder ulcer have been published) and the patient generally experiences mild post-embolization symptoms for few days.
PAE can be performed during a one-day hospitalisation and could be very attractive to patients which have insufficient benefit of medical treatment or who have side effects affecting their quality of life. The most used device for PAE is Embosphere® (Merit Medical). It bears the European CE (Conforme aux Exigences) marking for this specific indication and approximately 500 patients have been treated with it worldwide. Nonetheless, no big randomized study has proven its efficacy compared with best medical treatment. A study comparing PAE using Embosphere® and surgery (TURP) is currently enrolling patients; no patients could be included in France because men with BPH refused to be potentially assigned the surgical arm.
To properly evaluate PAE, the investigators designed the PARTEM trial, which has received the support of both the Societe Francaise de Radiologie (French society of radiology) and of the Association Francaise d'Urologie (French association of urology).
PARTEM will compare prospectively the benefit of PAE using Embosphere® to the benefit of combined medical treatment (Combodart®: Dutasteride 0.5mg Tamsulosin 0.4mg) at 9 months with an extended follow up at 24 months in order to evaluate the stability of results in both groups.
