Functional and oncological outcomes of patients aged <50 years treated with radical prostatectomy for localised prostate cancer in a European population.

Abstract

To address the biochemical and functional outcomes after radical prostatectomy (RP) of men aged <50 years in a large European population. Among 13,268 patients who underwent RP for clinically localised prostate cancer at our centre (1992-2011), 443 (3.3%) men aged <50 were identified. Biochemical recurrence (BCR) and functional outcomes (International Index of Erectile Function [IIEF-5], use of pads), were prospectively evaluated and compared between men aged <50 years and older patients. Men aged <50 years were more likely to harbour D'Amico low-risk (49.4 vs 34.9%, P < 0.001), organ-confined (82.6 vs 69.4%, P < 0.001) and low-grade tumours (Gleason score <7: 33.1 vs 28.7%, P < 0.001). Multivariate Cox regression analysis showed that age <50 years (hazard ratio 0.99; confidence interval 0.72-1.31; P = 0.9) was not a predictor of BCR. Urinary continence was more favourable in younger patients, resulting in continence rates of 97.4% vs 91.6% in most recent years (2009-2011) for patients aged <50 vs ≥50 years. After RP, a median IIEF-5 drop of 4 points in younger men vs 8 points in older patients was recorded (P < 0.001). Favourable recovery of urinary continence and erectile function in patients aged <50 years compared with their older counterparts was confirmed after multivariable adjustment. Men aged <50 years diagnosed with localised prostate cancer should not be discouraged from RP, as the postoperative rates of urinary incontinence and erectile dysfunction are low and probability of BCR-free survival at 2 and 5 years is high.
