Perceptions of medical status and treatment goal in older adults with advanced cancer.

Abstract

e23016 Background: Perceptions of medical status and treatment goal are often used to assess prognostic awareness, but whether these items fully capture patients’ understanding of their prognosis remains unclear. We sought to better understand these measures by investigating their relationship with quality of life (QOL), symptom burden, functional impairment, hospitalizations, and overall survival (OS). Methods: We enrolled patients age ≥70 years within 8 weeks of a diagnosis of incurable gastrointestinal cancer. We surveyed patients to assess perceptions of medical status [terminally ill vs not], treatment goal [curative vs non-curative], QOL (EORTC - Elderly Cancer Patients), symptom burden (Edmonton Symptom Assessment System [ESAS]), and functional impairment (activities of daily living [ADLs]). We used regression models adjusted for age, sex, and education to explore relationships between these items and patients’ QOL, symptom burden, functional impairment, risk of hospitalizations, and OS. Results: Of 132 patients approached, 103 (78.0%) enrolled (mean age 77.62 years, 47.6% female). Half (49.5%) reported a terminally ill medical status and nearly two-thirds (64.0%) reported a non-curative treatment goal, with 42.0% reporting discordant responses to these items. Patient report of a terminally ill status was associated with worse QOL (EORTC illness burden: 53.59 vs 35.26, p = .001), higher symptom burden (ESAS score: 28.15 vs 16.79, p = .002), more functional impairment (number of ADLs: 3.63 vs 5.24, p = .006), greater risk of hospitalizations (HR = 2.41, p = .020), and worse OS (HR = 1.93, p = .010). We found no associations between these outcomes and patient-reported treatment goal. Conclusions: In older adults with advanced cancer, half reported a terminally ill medical status and nearly two-thirds reported a non-curative treatment goal. Patient report of a terminally ill status was associated with worse QOL, symptom burden, functional impairment, risk of hospitalizations, and OS. We did not find associations between these outcomes and patient report of their treatment goal. Our findings suggest that these questions measure different constructs and more nuanced tools for assessing prognostic awareness are needed.
