Modeling of quality of life in older adults with advanced cancer: Data from a URCC NCORP multisite trial.

218Background: While the importance of symptom assessment is well recognized in Palliative Care (PC), limited evidence is available on the growing population of older adults with advanced cancer. Increasingly geriatric assessment (GA), which incorporates validated tools to assess health status, is advocated as a component of the care for older patients with cancer, but is not routinely incorporated into PC evaluations. We tested the hypothesis that variability in QoL for older adults with advanced cancer would be predicted by both symptoms and GA. Methods: Data from an ongoing cluster RCT conducted at 68 oncology practices were analyzed. Inclusion criteria were: > 70 years old, advanced solid tumor diagnosis, impairment in at least 1 GA domain (e.g., function). Multiple reliable and valid objective assessments and self-report measures for each GA domain were completed. Symptoms were assessed by MD Anderson Symptom Inventory (MDASI). Hierarchical regression modeling was conducted. The dependent variable wa...
