Purpose: Curative surgery for prostate cancer is uncommonly offered to patients aged ≥75, balancing functional outcomes against survival benefit. Improvements in robot-assisted radical prostatectomy (RARP) and increasing overall life expectancy have recently challenged this paradigm. We compared patient-reported outcome measures (PROMs) between elderly (≥75 years) and younger patients (<75 years). Methodology: Retrospective multicentric review was performed of all RARP patients between October 2016 to December 2023. Patients routinely completed pre-operative questionnaires including the 36-Item Short Form Survey (SF-36), International Index for Erectile Function (IIEF-5), International Prostate Symptom Score (IPSS) and Expanded Prostate Cancer Composite (EPIC). Patients were followed up with questionnaires at 6-weeks, 6-months and 1-year post-operatively. Results: A total of 397 patients were included (Younger;n=332[83.6%],Elderly;n=65[16.4%]). Elderly patients reported mental health improvement 6-months following RARP (SF-36 mean difference [MD] 4.82, p=0.01) without any significant differences in physical quality of life (MD -1.56, p=0.5) when compared to their younger counterparts. Elderly patients reported better outcomes compared to younger patients in terms of bowel 97.68±3.68 vs 92.24±11.96, p=0.001) and hormonal symptoms 96.82±3.75 vs 87.58±13.97, p<0.001) at 1-year. No differences were observed between groups in terms of sexual and urinary function. Conclusions: Elderly patients undergoing RARP report equally favourable post-operative outcomes and quality-of-life when compared to younger patients. Continence and sexual function remain important considerations in the post-operative recovery of all RARP patients.
