Background: Outcomes of older adults with pancreatic cancer are highly variable with increased susceptibility to chemotherapy toxicities and inferior survival compared to younger patients. Determining which older adults are at higher risk for adverse outcomes remains a clinical challenge. We evaluated the association of a novel patient-reported geriatric assessment (GA)-based frailty index with survival among older adults with pancreatic cancer. Methods: Older adults (≥60y) referred for initial consultation at the UAB GI oncology clinic were prospectively enrolled in the Cancer and Aging Resilience Evaluation (CARE) registry. All patients underwent a patient-reported GA capturing multiple aging-related domains of health. The 44-item CARE frailty index (CARE-FI) based on the principles of deficit accumulation was utilized to determine frailty. The primary outcome was overall survival (OS) from the time of GA. Kaplan Meier method was used to estimate OS and comparisons between groups were by log-rank. A multivariate Cox regression model adjusted for age, sex, race, and cancer stage. Results: A total 254 older adults with pancreatic cancer were included; median age 70y, 52.4% male, 77% non-Hispanic white and 43.4% with stage IV disease. Overall, 40.1% (n=102) were frail, 26.0% (n=66) pre-frail and 33.9% (n=86) robust. No significant clinico-demographic differences across the 3 frailty groups were found. Differences in OS over two-year period was observed across the three frailty groups by the KM method (p=0.008). In multivariate cox regression, frail status was associated with an increased risk of mortality (HR 1.9 [95% CI 1.19 – 2.98]; p=0.01) compared to robust status after adjustment for aforementioned confounders. Conclusions: The CARE-FI is a novel frailty index built on the principles of deficit accumulation using a patient-reported GA and is independently associated with survival among older adults with pancreatic cancer.
