Nutrition and pediatric cancer.

Good nutritional status is very important in patients with malignant diseases, especially during chemotherapy. It is most important to avoid cachexia: One should avoid factors that may cause it or feed the patient by tube or intravenously if not possible orally, even if it is necessary to give total parenteral nutrition. The target is to ensure that the infants and children with malignant diseases during chemotherapy will retain optimal nutritional condition, which helps the children's growth development and helps them tolerate the treatment better. As the patient's age changes, so the need for certain nutritive materials is modified, and the usage is changed also.
