[Artificial nutrition in bone marrow transplantation].

The issue of nutritional support in oncologic patients is reviewed. Special reference is made in relation to patients undergoing bone marrow transplant and their possible digestive tract and nutritional changes induced by the different therapies available in these situations. Nutritional evaluation and caloric and nitrogen requirement calculations have been proposed. Likewise, several possibilities have been considered regarding the route of administration, timing and quality of the nutriments to be administered, both to adult and pediatric patients.
