Abstract
This study further discussed the 2021 ESPEN practical recommendations for nutritional support in oncology. The updated version of the 2021 ESPEN practice guidelines differs slightly from the 2017 version and contains flowcharts to facilitate the use of the guidelines in clinical practice, which is also relevant for domestic healthcare. ESPEN-2021 Clinical Guidelines, which offer practical solutions in all areas of oncology, are significant to both oncologists and allied specialists working in oncology. The second part of the review discusses particular issues of nutritional support for patients with cancer and analyzes the domestic experience of their use. The review provides the main protocols for artificial nutrition in surgery, during irradiation, and in drug therapy in patients in remission and at the palliative stage and proves the need to maintain physical activity in patients with cancer. The presented practical guidance allows organizing an adequate supply of nutrient substrates to patients with cancer receiving various types of anticancer treatment, in remission, and at the stage of palliative care.
