Abstract

Introduction: Cancer-related fatigue (CRF) is the most commonly reported treatment-related side effect of prostate cancer (PCa). Recognition of financial hardship among cancer survivors is growing. We investigated, for the first time, associations between levels of financial stress and CRF among PCa survivors. Methods: We used data from PCa survivors who had been identified through two population-based cancer registries covering the Republic of Ireland and Northern Ireland and had completed a postal questionnaire. CRF was measured by the fatigue subscale of the EORTC QLQ-C30. Financial stress was assessed as household ability to make ends meet (i) pre-diagnosis and (ii) at questionnaire completion (post-diagnosis). Multivariable logistic regression was used to relate financial stress to clinically important CRF (fatigue subscale score ≥ 39 of a possible 100). Results: Two thousand four hundred fifty-eight PCa survivors were included. Of these, 268 (10.9%) reported pre-diagnosis financial stress only, 317 (12.9%) post-diagnosis stress only and 270 (11.0%) both pre- and post-diagnosis stress (cumulative stress); 470 (19.1%) reported clinically important CRF. After controlling for confounders, survivors with cumulative financial stress exposure were significantly more likely to have CRF (OR = 4.58, 95% CI 3.30–6.35, p < 0.001), compared with those without financial stress. There was a suggestion of a dose-response relationship (OR = 1.83, 95% CI 1.27–2.65, p = 0.001 for pre-diagnosis financial stress only; and OR = 4.11, 95% CI 3.01–5.61, p < 0.001 for post-diagnosis financial stress only). Conclusions: Financial stress may be an independent risk factor for CRF. Implications for Cancer Survivors: There may be benefits in targeting interventions for reducing CRF towards survivors with financial stress, or developing strategies to reduce financial stress.
