Although the nutritional approach, especially when delivered through a gastric or jejunal tube or in
a central vein, is handled by the nutritional support team or a specialist in nutrition, it is the
responsibility of the oncologist, who knows the natural history of the disease and the impact of the
oncologic therapy, to identify the potential candidates for the nutritional support, to recommend
the nutritional strategy and to integrate it within the oncologic program. If gastrointestinal function
is preserved, the initial nutritional approach should be through oral supplementation, followed
by tube feeding if previous attempts are unsuccessful or upper gastrointestinal tract is not
accessible.
