Nutrition and Body Composition in Acute Lymphoblastic Leukemia
Completed · Phase 2
Conditions studied: Precursor Cell Lymphoblastic Leukemia-Lymphoma, Vitamin D Deficiency
In brief
Many adolescents with acute lymphoblastic leukemia (ALL) have been found to have low bone density by the end of treatment. This can lead to long-term suffering in survivors due to poor bone health. Vitamin D is known to be associated with bone health and previous research has established that Vitamin D insufficiency is very common at diagnosis of ALL and worsens over the course of treatment. Researchers have also learned that a relationship exists between both Vitamin D and fat tissue and ALL and fat tissue. In adolescents being treated for ALL as well as in early survivors, this randomized study will therefore examine the effect of Vitamin D and calcium supplementation on correcting Vitamin D insufficiency and on improving bone density in the context of changes in body composition and body fat. Bone density will be measured by a radiology exam called qCT (quantitative computed tomography) while body composition and body fat will be measured by a different radiology exam called a DXA (dual energy x-ray absorptiometry scan) . The study will also examine in depth the relationship between these three elements - Vitamin D insufficiency, obesity, and ALL - and their impact on bone density.

You may qualify if…
- GROUP A: Patients with newly diagnosed ALL
- Are greater than or equal to 10 years of age and less than or equal to 21 years of age at diagnosis of ALL
- Have a new diagnosis of untreated ALL classified as "high risk" per NCI criteria (due to being greater than 10 years of age)
- Are beginning treatment with a Children's Cancer Group/Children's Oncology Group "high risk" protocol with a 4-drug induction including steroids
- Are not pregnant
- GROUP B: Early survivors of ALL
- Were treated for ALL and remain in first CR1 (complete remission)
- Were equal to or greater than 10 years of age and less than or equal to 21 years of age at diagnosis of ALL
- Have completed treatment on or as per a Children's Cancer Group/Children's Oncology Group "high risk" protocol between 12 and 48 months prior to enrollment in this study (consisting of a plan for a 4-drug induction including steroids in Induction, Delayed Intensification, and steroid pulses in Maintenance. Steroids are allowed to have been discontinued due to toxicity).
- Are not pregnant
- GROUP C: Siblings of Group A
- Are either a full-sibling or a half-sibling of a patient in Group A
- Are living at the same residence as the sibling/half-sibling from Group A
- Are greater than or equal to 10 years of age and less than or equal to 21 years of age at the time of study entry, and within 3 years of the age diagnosis of ALL in the sibling/half-sibling from Group A
- Are on the same Vitamin D supplementation regimen (if any) as the sibling from Group A at the time of his or her diagnosis
- Exclusion Criteria (All Groups):
- Have a diagnosis of Down syndrome (Trisomy 21) or any genetic disease associated with abnormal bone development
- Are undergoing treatment with other medicines that affect bones including chronic use of of steroids, bisphosphonate therapy, or Vitamin D at average dose greater than 400 international units (IU)/day
- Have an underlying diseases altering body structure (i.e. missing a limb, severe dysmorphism) or severely affecting mobility (i.e. total or hemiparesis)
- Have a history of chemotherapy or radiation for other cancers
- Cannot complete the radiology exams/radiology exams uninterpretable (i.e. people with a hip replacement or prosthesis)
