Anxiety is Associated With Geriatric Assessment Impairments and Reduced Quality of Life Among Older Adults With Colorectal Cancer: Results From the CARE Registry.

BACKGROUND: Colorectal cancer (CRC) preferentially affects older adults. Modifiable factors, such as anxiety, can be measured as part of cancer-specific geriatric assessments (GA) completed prior to the start of treatment. We hypothesized that anxiety is prevalent among older adults with CRC and is associated with increased depression, increased frailty, and impaired health-related quality of life (HRQOL).

PATIENTS AND METHODS: Patients ≥60 years old with newly diagnosed CRC completed a cancer-specific GA called the Cancer and Aging Resilience Evaluation (CARE). Between September 2017 and February 2023, we analyzed patients with CRC who had not yet received any systemic treatment. Anxiety was assessed using the Patient-Reported Outcomes Measurement Information System (PROMIS) Anxiety 4-item short form and reported as t-scores. We used modified Poisson models with robust variance estimation to assess for differences in the prevalence of depression, frailty, and impaired HRQOL.

RESULTS: We analyzed 277 older adults with CRC. The median age of the study sample was 68 years. 57% were male, 72% were non-Hispanic White, and most had advanced CRC (35% stage III and 39% stage IV). Moderate/severe anxiety was present in 17% of older adults with newly diagnosed CRC. In adjusted models, as compared to patients without moderate/severe anxiety, patients with moderate/severe anxiety had significantly increased risk of depression (prevalence ratio [PR] 7.60, CI 4.90-11.78), frailty (PR 4.93, CI 3.01-8.07), impaired physical HRQOL (PR 3.57, CI 2.03-6.28), and impaired mental HRQOL (PR 3.82, CI 2.12-6.89).

CONCLUSION: Among older adults with CRC, anxiety is associated with increased depression and frailty as well as reduced HRQOL.
