The Impacts of Prognostic Awareness on Mood and Quality of Life Among Patients With Advanced Cancer

Abstract

Background: Accurate awareness of the prognosis is an important factor in the treatment decision of patients with advanced cancer; however, prognostic disclosure is still subject to debate because it can reduce patient’s satisfaction and increase depression. Aim: The purpose of this study is to assess whether patients’ prognostic awareness is associated with decreased quality of life (QoL) or increased depressive mood in patients with advanced cancer Design and Participants: In this cohort study, 386 patients with advanced cancer were recruited across 3 periods from December 2016 to August 2018. The outcome of this study was a change in QoL and depression according to the patients’ prognostic awareness at baseline, 3 months, and 6 months. Results: This study found significant differences in changes of QoL based on patients’ prognostic awareness. From baseline to 3 months, emotional functioning (P =.039), pain (P =.042), existential well-being (P =.025), and social support (P =.038) subscale scores improved significantly more in those with lack of prognostic awareness. Over 6 months, the group without prognostic awareness improved significantly in terms of physical functioning (P =.037), emotional functioning (P =.002), nausea/vomiting (P =.048), and constipation (P =.039) subscale scores and existential well-being scores (P =.025). No significant difference between the groups was found in terms of depression. Conclusion: Accurate prognostic awareness may pose harm and may provide no additional benefits in terms of QoL and mood among patients with advanced cancer for a short period of time. © The Author(s) 2020.
