Quality of life in young men after radical prostatectomy: Results from the CaPSURE registry

Abstract

4576 Background: Over the past two decades, the age at diagnosis and treatment of men with prostate cancer (CaP) has steadily declined. Previous work suggests that younger men have similar or improved pathologic and clinical outcomes compared to older men. The literature on quality of life (QOL) following local treatment for CaP has primarily focused on comparing treatment modalities rather than specific age groups. This analysis explored QOL outcomes in younger men following primary curative treatment for localized prostate cancer. Methods: This was a secondary analysis of a prospectively collected cohort from the CaPSURE (Cancer of the Prostate Strategic Urologic Endeavor) registry. Men who underwent radical prostatectomy (RP) for localized disease and completed the UCLA Prostate Cancer Index (PCI) pre- and one-year post-surgery were identified. Men were grouped based on age (< 55, 55–64, ≥ 65 years). A severe decline in PCI domains from pre- to post-RP was defined as a decrease of one standard deviation from the pre-RP score. PCI scores were compared across age groups, and a multivariate model created to analyze the predictors of severe declines in PCI domains. Results: 1,143 men were identified, with 190, 526 and 427 men in the three age groups, respectively. Younger men had significantly higher mean scores one-year after RP in the urinary function (UF), urinary bother (UB) and sexual function (SF) domains of the PCI. The proportion of men with a severe decline in UF, UB and SF was not significantly different in the age groups (range 49–54%, 32–38%, 58–51% respectively). However, a severe decline in SB was more common in the youngest age group than in the oldest (54% vs. 36%, p < 0.01). With the youngest men as the reference group in the multivariate model, the oldest age group was 40% less likely to have a severe decline of SB (OR = 0.60, 95% CI 0.41–0.90, p = 0.04) but trended toward a higher risk of severe decline in UB (OR = 1.27, 95% CI 0.85–1.89, p = 0.08). Conclusions: Age predicts disease-specific QOL changes at one-year following RP. Younger men had significantly better mean UF, UB, and SF domain scores one-year after RP than did their older counterparts. Men < 55 years old are more likely than older men to experience a severe decline of sexual bother but trend toward a lower risk of a severe urinary bother.
