Description

This study is for older children, adolescents, and young adults with B-cell Acute Lymphoblastic Leukemia (B-ALL). Higher amounts of body fat is associated with resistance to chemotherapy in patients with B-ALL. Chemotherapy during the first month causes large gains in body fat in most people, even those who start chemotherapy at a healthy weight. This study is being done to find out if caloric restriction achieved by a personalized nutritional menu and exercise plan during routine chemotherapy can make the patient's ALL more sensitive to chemotherapy and also reduce the amount of body fat gained during treatment. The goals of this study are to help make chemotherapy more effective in treating the patient's leukemia as demonstrated by fewer patients with leukemia minimal residual disease (MRD) while also trying to reduce the amount of body fat that chemotherapy causes the patient to gain in the first month.
