Impact of cachexia at diagnosis on radiotherapy utilization and survival in non-small cell lung cancer.
2016
133 Background: The presence of cachexia at the time of cancer diagnosis and its influence on disease management and treatment outcomes for patients receiving radiotherapy are poorly described. Here, we assess the role of baseline cachexia in patients with NSCLC on first-line treatment modality and clinical outcomes. Methods: Retrospective review of medical records identified 1,334 patients with NSCLC consecutively treated at a tertiary care health system between 1/1/06 and 12/31/13. Cachexia was defined using the well-accepted and validated international consensus definition. The delivery of radiotherapy and its treatment intent were abstracted. Results: The cohort included a representative group of patients with a median age at diagnosis of 64 years, 47% females, and 32% patients of non-White race. Stage at diagnosis was I, II, III, and IV in 291, 105, 356, and 578 (43.3%) patients, respectively. Cachexia was present at the time of diagnosis in 403 (30.2%) patients including 18%, 14%, 32%, and 39% of st...
