Managing malnutrition in Oncology

Identification of malnutrition

Identification of malnutrition through screening is imperative, as recognised by the National Institute for Health and Care Excellence (NICE)1 and the European Society for Clinical Nutrition and Metabolism (ESPEN)2,3. Screening should be performed at the time of diagnosis.

Oral nutritional supplements (ONS) play a role in cancer patients' journey

ESPEN (2016)and ESPEN (2021)3 highlight the role that nutritional intevention plays in Oncology patients.

Nutritional interventions are recommended to increase oral intake in cancer patients who are able to eat but are malnourished or at risk of malnutrition. This includes dietary advice, the treatment of symptoms and derangements impairing food intake (nutrition impact symptoms), and offering oral nutritional supplements.


“During intensive chemotherapy and after stem cell transplantation ESPEN recommends to maintain physical activity and to ensure adequate nutritional intake. This may require enteral and/or parenteral.” 2,3


“During radiotherapy with special attention to radiotherapy of the head and neck, thorax and gastrointestinal tract, an adequate intake should be ensured primary by, individualised nutritional counselling and/or oral nutritional supplements (ONS), in order to avoid nutritional deterioration, maintain intake and avoid radiotherapy interruptions.” 2,3


“For all cancer patients undergoing either curative or palliative surgery, ESPEN recommends management within an enhanced recovery after surgery (ERAS) program; within this program every patients should be screened for malnutrition and if deemed at risk, given additional nutritional support.” 2,3
“For those at risk of malnutrition or already malnourished, appropriate nutritional support  is recommended during hospital stay and post discharge.” 3

Palliative Care

“ESPEN recommends implementing nutritional interventions in patients with advanced cancer only after considering together with the patient the prognosis of the malignant disease and both the expected benefit on quality of life and potentially survival as well as the burden associated with nutritional care.” 2,3
