Improving survival for children with cancer has been attributable to the provision of intensive therapies (i.e., high-dose chemo/radiotherapy and Hematopoietic Cell Transplantation-HCT). However, as a result of these treatments, most children suffer and experience severe and distressing treatment-related symptoms such as taste and smell alterations that can hamper the quality of life of these patients by influencing their appetite, body weight, and psychological well-being. In addition, one of the major adverse side effects during Hematopoietic Stem Cell Transplantation (HSCT) is malnutrition due to the many treatments related factors such as altered taste and smell and dry mouth. Since children have more nutritional requirements for growth and development, they are more vulnerable to malnutrition.
