Patient-reported anxiety with localized prostate cancer treated with stereotactic body radiation therapy (SBRT).

Abstract

52 Background: Anxiety is a common aliment among elderly men. It may be negatively impacted by the diagnosis of cancer. Effective cancer treatment may alleviate anxiety. The EORTC QLQ-ELD14 (ELD14) is a validated questionnaire, which evaluates patient reported anxiety. Using the ELD14 questionnaire, this study assesses the trends in prostate cancer patient’s anxiety before and after treatment with SBRT. Methods: All patients with localized prostate cancer who received SBRT at Georgetown University Hospital from 2007 to 2016 were eligible for inclusion in this cross-sectional cohort. The ELD14 questionnaire was used to assess quality of life before and following treatment. Initially, approximately 267 patients (median age of 70) responded to the ELD14 questionnaire. This study is focused on questions related to patient’s anxiety regarding their families, future, health and end of life. The responses to these questions were grouped into three clinically relevant categories (not at all, a little and quite a bit to very much). Results: Prior to treatment, 19% of patients felt quite a bit or very much worried about their families coping with their illness. This decreased to 9% at 24 months post-SBRT (p = 0.007). Initially, 27% of patients reported concerns for the future of their families, which subsequently decreased to 20% at 24 months (p = 0.15). At initial consult, 32% of patients reported being worried about their future health. This decreased to 13% at 24 months (p < 0.001). Twenty percent of patient reported concern about their future at initial consult; this declined to 11% at 24 months (p = 0.03). And finally, self reported anxiety about end of life was 18% at the initial consult and 12% at 24 months (p = 0.16). Conclusions: Self-reported anxiety surrounding family, health and future is prevalent amongst prostate cancer patients at initial evaluation. Significant reduction in anxiety is observed in our cohort post-SBRT. Further investigations in the causes of pre and post-treatment anxiety may offer valuable insight into preventable root causes and improvement in patient’s quality of life.
