Abstract

Objectives: Prognostic awareness relates to patients' capacity to understand their prognosis and the likely illness trajectory. Based on the current evidence, accurate PA is associated with decrease in uncertainty, depresivity, and anxiety and with increase in quality of life. However, other studies found also negative associations of PA and quality of life and mental health. This systematic review synthesizes the available literature on factors associated with accurate prognostic awareness in patients with cancer.

Methods: Four databases were systematically searched for studies assessing prognostic awareness in patients with cancer. In these studies, we looked for factors positively or negatively associated with prognostic awareness. Included studies were critically appraised for methodological quality.

Results: We screened 28 078 studies and included 70. In these studies, 102 factors were found to be related to prognostic awareness positively or negatively. Identified factors were divided into seven groups: demographic factors, factors related to coping, health condition factors, psychological factors, factors associated with end-of-life care, factors related to communication, and factors related to relatives. Prognostic awareness differs according to age, personality, communication with doctor, disease stage, or being outpatient. For some factors such as depression, anxiety, or quality of life, higher level of these factors was found to be associated with accurate and inaccurate prognostic awareness.

Conclusions: Prognostic awareness is a complex phenomenon associated with various positive and negative associations for patients with cancer. Clinicians must consider individual preferences and values of patients and their families when discussing prognosis and must be prepared for potential adverse outcomes.
