OBJECTIVE: To provide comparative data on quality of life (QoL) after prostate cancer treatment to help patients make an informed decision regarding their choice of treatment. METHODS: Patients with pathologically proven, non-metastatic, T1-T3bN0 prostate cancer were included in this prospective non-randomized study if they were to receive treatment with curative intent. Sample size was at least 181 patients per cohort/treatment type. QoL was recorded at baseline and at each follow-up using the Expanded Prostate Cancer Index Composite (EPIC) instrument. The minimal clinically important difference was defined as half of the standard deviation of the baseline score for each domain. A mixed effects model was used to compare the different treatments. Data are presented on the brachytherapy and the bilateral nerve-sparing robot-assisted radical prostatectomy (RARP) cohorts. Hormonotherapy was not allowed. RESULTS: Between November 2007 and January 2013, 181 patients who received brachytherapy and 210 patients who underwent RARP were included. Of the patients who underwent RARP, 178 had bilateral nerve-sparing and were included in the present analysis. Response rate to EPIC questionnaires were higher in the brachytherapy than in the RARP arm: 82% vs 57% at 2 years after treatment and 55% vs 45% at 4 years after treatment. In the mixed effects model, patients in the RARP arm had better QoL with regard to urinary irritation/obstruction or bother and bowel function, and lower QoL regarding sexual function and urinary incontinence. Results were confirmed in a propensity score-matched model. Patient satisfaction was significantly higher in the brachytherapy group at 1, 2 and 3 years after treatment. CONCLUSION: This prospective non-randomized study shows long-term differences in QoL domains after bilateral nerve-sparing RARP and brachytherapy. Differences in patient satisfaction should be further explored. These results could be used to counsel patients in the decision-making process. Published 2017.
