Researchers are studying ways to predict if cancer patients are at risk for poor nutrition during their chemotherapy treatment. They hope to identify children with nutrition problems early in treatment. This may help prevent weight loss and other nutrition problems later in treatment.

The PEDSGA is a newly developed nutrition tool that includes a training manual that be used to teach health care professionals to identify at-risk patients by doing a nutrition physical exam. The PEDSGA also includes questions that the patient/caregiver answers regarding appetite, recent treatment, and activity level. This method of screening is new and may be able to identify at-risk patients better than the standard method. This study will use both methods and evaluate the two, in hope of determining which method works best to identify at-risk patients.
