Predictors and trajectory of performance status in patients withadvanced cancer: A secondary data analysis of the international EuropeanPalliative Care Cancer Symptom study

摘要

Background:Performance status, a predictor of cancer survival, and ability to maintain independent living deteriorate in advanced disease. Understanding predictors of performance status trajectory could help identify those at risk of functional deterioration, target support for independent living and reduce service costs. The relationship between symptoms, analgesics and performance status is poorly delineated.
