Prospective four years of evaluation of erectile function after low-dose-rate prostate brachytherapy using baseline IIEF-5 > 16. J Contemp Brachytherapy 2019; 11:195-200.

Abstract
Purpose Prostate brachytherapy (BT) is a validated treatment for localized prostate cancer (CaP) and an attractive therapy option for patients seeking to preserve erectile function (EF). The aim of this paper is to prospectively assess EF evolution during 4 years after BT. Material and methods Between February 2007 and July 2012, 179 patients underwent an exclusive Iodine-125 BT, for low-intermediate favorable risk CaP of whom, 102 had an initial international index of erectile function 5 score (IIEF-5) > 16 and were included in the study. Of those, 12.7% received neo-adjuvant hormonotherapy (HT) to decrease the prostate volume. Post-BT intake of phosphodiesterase inhibitors (PDE5i) was not an exclusion criterion. Erectile function was prospectively assessed using a validated questionnaire IIEF-5 before treatment and annually for 4 years. Results At 1-year follow-up, 54% of patients preserved an IIEF-5 > 16 and only 8% suffered from severe ED. During the next 3 years, the results were not statistically different. The mean IIEF-5 lost 4 points during the first year, 17 vs. 21, and remained stable during the following 3 years. We did not find any significant differences in the proportion of patients treated by PDE5i (18-20%). As for patients with a normal preoperative IIEF-5 (> 21) (n = 52), 35-42% preserved a normal EF and 71-77% maintained an IIEF-5 > 16, including 13-19% of patients who needed PDE5i. Those results were stable for over 4 years. Conclusions During the first 4 years after BT, more than half of patients maintained an IIEF-5 > 16, and EF results remained stable. Severe erectile dysfunction (ED) was very rare.

Abstract
PURPOSE To evaluate erectile function (EF) prospectively from 1 to 2 years post-brachytherapy in patients with a baseline IIEF5 score>16. METHODS Between 2007 and 2012, 179 patients underwent an exclusive brachytherapy for localised low risk prostate adenocarcinoma. Neo-adjuvant hormotherapy (15.6%) and post-brachytherapy intake phosphodiesterase inhibitors (PDE5i) were not considered as exclusion criteria. EF was evaluated via a scoring questionnaire IIEF5 before the surgical implantation, at month 12 and 24 post-operation. Only patients with an initial IIEF5 score>16 were included. RESULTS Of the 179 patients, 102 (57%) had a baseline IIEF5>16. At 12 months, 51.1% maintained an IIEF5>16 and 24.5% had a mild to moderate erectile dysfunction (ED), so that a total of 75.6% with IIEF5≥12. About 18% of patients had used PDE5i. At 24 months, 53.2% had an IIEF5>16 and 80.6% had an IIEF5≥12. Severe ED was reported in only 14.5% of the patients. The mean IIEF5 was 16.2 with an average decline of 5 points from the initial stage. All patients who were treated with PDE5i (27%) could have sexual intercourse. EF at baseline was reported as the only predictive factor of ED in multivariate analysis, 70% of patient without ED initially, had an IIEF5>16 at 1 and 2 years. CONCLUSION Severe ED was quite rare (14%) during the first 2 years post-brachytherapy and more than half of patients maintained an IIEF5>16. The main predictive factor was the erectile function at baseline. LEVEL OF EVIDENCE 4.
