Objectives: This study aimed to identify the clinical usefulness of assessing nutritional status using validated tools for the indication of enteral nutrition for patients with incurable cancer in palliative care.
Methods: In this prospective cohort study, patients were assessed for nutritional risk using the Patient-Generated Subjective Global Assessment and for cancer cachexia (CC) using the modified Glasgow Prognostic Score upon enrollment and after ∼30 d. The outcome was stable or improved Karnofsky Performance Status. Logistic regression models were used, providing the odds ratio (OR) and 95% confidence interval (CI).
Results: A total of 180 patients participated. The only nutritional status parameter that was associated with function was CC. The less severe the CC, the more likely Karnofsky Performance Status was to remain stable or improve over 30 d (non-cachectic: OR = 1.95; 95% CI, 1.01-3.47; malnourished: OR = 1.06; 95% CI, 1.01-1.42). Furthermore, white skin color (OR = 1.79; 95% CI, 1.04-2.47), higher educational level (OR = 1.39; 95% CI, 1.13-2.78), and inadequate calorie intake (OR = 1.96; 95% CI, 1.02-2.81) were also associated with the outcome.
Conclusions: Using the modified Glasgow Prognostic Score to identify the existence and severity of CC, which is associated with function, has the potential to help clinical decision making concerning the indication of enteral nutrition in patients with incurable cancer receiving palliative care.
