Background: Frailty is emerging as an important determinant for quality of life (QoL) and emotional health in older patients with cancer, and specifically in long-term prostate cancer survivors, but quantitative studies are lacking. The current study assesses the prevalence of frailty and its association with QoL and emotional health in long-term prostate cancer survivors after radical prostatectomy. Patients and Methods: A total of 2,979 prostate cancer survivors from the multicenter German Familial Prostate Cancer cohort completed questionnaires on frailty (Groningen Frailty Indicator [GFI]), QoL (EORTC QoL Questionnaire-Core 30), and emotional health (anxiety/depression symptoms via the Patient Health Questionnaire-4). Modified Poisson regression analysis was used to assess factors associated with frailty. Results: Average patient age was 79.4 years [SD, 6.4 years] and average time since radical prostatectomy was 17.4 years [SD, 3.8 years]. Among the cohort, 33.1% (n=985) of patients were classified as frail (GFI ≥4). Frail patients reported worse emotional health than nonfrail patients (depression symptoms: 24.0% vs 4.0%; anxiety symptoms: 20.6% vs 2.0%; both P<.001) and lower QoL (mean [SD], 53.4 [19.2] vs 72.7 [16.0]); P<.001). Higher age (relative risk [RR], 1.02; 95% CI, 1.01–1.03) and worse depressive (RR, 1.18; 95% CI, 1.12–1.24) and anxiety symptoms (RR, 1.17; 95% CI, 1.11–1.23) were associated with frailty. Living in a partnership (RR, 0.76; 95% CI, 0.67–0.86) and a higher QoL (RR, 0.86 for a 10-point increase; 95% CI, 0.84–0.89) were associated with nonfrailty. Conclusions: In a large German cohort, every third long-term prostate cancer survivor after radical prostatectomy was frail. The association of frailty with lower QoL and poorer mental health indicates the need for an integrated care approach including further geriatric assessment and possible interventions to improve health outcomes targeted to frail patients.
