Relationship between perceptions of treatment goals and psychological distress in patients with advanced cancer.
11621 Background: Several studies have demonstrated discordance between how patients perceive their goal of treatment versus how they perceive their oncologist’s goal. Studies evaluating the extent and risk factors of this discordance are lacking. Methods: We conducted a cross-sectional study of 559 patients with incurable lung, gastrointestinal, breast, and brain cancers. We used the Perception of Treatment and Prognosis Questionnaire to assess patients’ perceptions of both their treatment goal and their oncologist’s goal and categorized responses: 1) patients who reported that both their goal and their oncologist’s goal was concordant (either to cure or not to cure); and 2) patients who reported discordant perceptions of their goal versus their oncologist’s goal. We assessed patients’ psychological distress using the Hospital-Anxiety-and-Depression-Scale and used linear regression to assess the relationship between patients’ perceptions of their treatment goal and psychological outcomes. Results: 61.7% of patients reported that both their goal and their oncologist’s goal was non-curative; 19.3% reported that both their goal and their oncologist’s goal was to cure their cancer; and 19.0% reported discordance between their goal and their perception of the oncologist’s goal. Older age (OR = 0.98, P = 0.01), non-Hispanic ethnicity (OR = 0.31, P = 0.049), and higher education (OR = 0.62, P = 0.042) were associated with lower likelihood of reporting discordant goals. Patients with discordant perceptions of their goal and their oncologist’s goal reported higher anxiety (B = 1.56, P = 0.003) compared to those who reported that both their goal and their oncologist’s goal was curative. Patients who reported both their goal and the oncologist’s goal was non-curative had higher depression symptoms (B = 1.06, P = 0.013) compared to those who reported that both their goal and the oncologists’ goal was curative. Conclusions: One-fifth of patients with advanced cancer report discrepancies between their perceptions of their own and their oncologists’ treatment goal which is associated with psychological distress. Tools are needed to identify patients at risk of cognitive dissonance about their prognosis.
