“…In this context, the correct assessment of energy requirement becomes a crucial step in choosing the type and composition of the nutritional therapy. Several studies [ 42 , 43 , 44 , 45 , 46 ] emphasize the importance of indirect calorimetry as the goal standard in evaluating the real energy requirements in cancer patients. Predictive formulas, such as the Harris–Benedict equation, do not consider the cancer energy expenditure, underestimating the real REE of the patient [ 47 ].…”

Home Artificial Nutrition and Energy Balance in Cancer Patients: Nutritional and Clinical Outcomes

Malnutrition is one of the main factors determining cachexia syndrome, which negatively impacts the quality of life and survival. In cancer patients, artificial nutrition is considered as an appropriate therapy when the impossibility of an adequate oral intake worsened nutritional and clinical conditions. This study aims to verify, in a home palliative care setting for cancer patients, if home artificial nutrition (HAN) supplies a patient’s energy requirement, improving nutritional and performance status. A nutritional service team performed counseling at a patient’s home and assessed nutritional status (body mass index, weight loss in the past 6 months), resting energy expenditure (REE), and oral food intake; Karnofsky Performance Status (KPS); cachexia degree; and survival. From 1990 to 2021, 1063 patients started HAN. Among these patients, 101 suspended artificial nutrition for oral refeeding. Among the 962 patients continuing HAN until death, 226 patients (23.5%) survived 6 weeks or less. HAN allowed to achieve a positive energy balance in 736 patients who survived more than 6 weeks, improving body weight and KPS when evaluated after 1 month of HAN. Advanced cancer and cachexia degree at the entry of the study negatively affected the positive impact of HAN.
