Factors associated with physical and mental health symptoms in pancreatic adenocarcinoma: a population-based cohort study

Year: 2026

Type: article

Abstract: Background: Patients with pancreatic ductal adenocarcinoma (PDAC) experience debilitating symptoms, yet factors associated with symptom burden and severity are not well described. Methods: This population-based cohort study included patients diagnosed with PDAC and who completed Edmonton Symptom Assessment System (ESAS) between 1 month before and 2 months after diagnosis between January 1, 2007 and December 31, 2020 in Ontario, Canada. The ESAS contains 9 symptoms on a scale from 0 to 10. The primary outcome was moderate to severe (ESAS scores ≥4) symptoms (pain, tiredness, nausea, depression, anxiety, drowsiness, loss of appetite, well-being, and shortness of breath) 2-6 months after diagnosis. We used multivariable logistic regression models to evaluate associations between the primary outcome and baseline demographic and clinical variables, cancer-specific factors, and baseline symptom scores. Results: We included 4918 patients (mean age 68 years, 52% male). Near the time of diagnosis, 13.8% (nausea) to 38.5% (well-being) of patients reported moderate to severe symptoms. At 2-6 months after diagnosis, 23.0% (dyspnea) to 57.5% (poor well-being) reported moderate to severe symptoms. A range of baseline demographic, clinical, and cancer-specific risk factors were identified for reporting of moderate to severe symptoms. The presence of baseline symptoms for each of the 9 included symptoms was associated with reporting of the same symptom with moderate to high severity 2-6 months after diagnosis. Conclusions: Patients with PDAC face a high symptom burden following diagnosis. Universal physician symptom screening for patients diagnosed with PDAC may enable improved symptom identification and management.
