Ireland has since 1994, higher levels of PSA testing and Prostate Cancer (PCa) in Republic of Ireland (ROI) compared with N. Ireland (NI). We investigate, health effects of different intensities of PCa investigation and treatment.
Postal questionnaires to PCa survivors 2-18 years post diagnosis on physical symptoms and Health Related Quality of Life (HRQoL) at questionnaire completion. Survivors were analysed separately for ROI and NI, for categories at diagnosis ‘late disease’ defined as stage III/IV and any Gleason Grade (GG) and ‘early disease’ defined as stage I/II and GG 2-7. Data were weighted by age, jurisdiction and time since diagnosis. Univariate and multivariate results are presented.
3,348 (54%) men responded. ROI responders were younger (average age diagnosis 65.3 vs 67.1 years); more likely to present asymptomatically (66% vs 41%); without comorbidities (45% vs 58%) and with early disease. Urinary incontinence was (16%) similar in early and late group for NI and ROI, impotence similar for NI and ROI, lower in early than late disease (56% vs 67%). In early disease, only bowel problems (NI=21%, ROI=12%) and fatigue (NI=29%, ROI=17%) were significantly different. Multivariate modelling explained fatigue as treatment related.
In late disease NI vs ROI men reported higher levels of breast changes (23% vs 9%) and hot flashes (41% vs 19%) which remained in multivariate modelling however, when men on ADT were analysed separately no significant differences remained. Differences in HRQoL were minimal.
Similar health outcomes were reported however the increased intensity of investigation has resulted in additional men with ongoing incontinence and/or impotence in ROI.
