Brief Summary
Research studies have shown that children who are long-term survivors of childhood leukemia may be at greater risk for early bone loss called osteoporosis. This bone loss may lead to a greater risk of broken bones and other spine and bone problems. However, researchers still do not know much about how frequently this long-term side effect may occur and how severe the problem is. St. Jude Children's Research Hospital researchers want to determine the frequency and severity of this side effect. They are also studying whether taking calcium and Vitamin D supplements can help children at risk for osteoporosis and if certain factors can be identified -- such as age at diagnosis, cancer treatments, or family history -- that may increase the chances of having osteoporosis. Researchers will take an x-ray study called quantitative computed tomography (QCT) to measure bone mineral density (BMD). The BMD is a measure of bone strength. If a subject's BMD falls below the average, he/she will be assigned to one of two groups. Subjects will be randomly assigned (like tossing a coin) to receive calcium and vitamin D pills. The other half will receive placebo pills that look like the calcium and vitamin D pills.

Outcome Measures
Primary Outcomes (4)
Effect of Taking Calcium and Vitamin D Supplements on Bone Mineral Density (BMD)
The effect of taking calcium and vitamin D supplements was measured using Quantitative Computed Tomography (QCT) to calculate a QTC Z score. A standardized Z-score was calculated to indicate the difference between the patient's Bone Mineral Density (BMD) and the mean value for age and gender-appropriate controls. Z-scores from 0 to +2 are considered normal, above +2 are considered to be elevated, from 0 to -1 are considered to represent a mild BMD deficit, between -1 and -2 are considered to represent moderate deficits, and below -2 are considered to represent severe deficits.
Baseline, 12 months, 24 months, and at 36 months or study end
Bone Mineral Density in Male and Female ALL Survivors
Using bone mineral density Z-score, assess relationship between predisposing factors (gender) and bone mineral density; a negative value indicates a deficit in bone mineral density.
Baseline
Bone Mineral Density by Race of ALL Survivors
Using bone mineral density Z-score, assess relationship between predisposing factors (race) and bone mineral density; a negative value indicates a deficit in bone mineral density.
Baseline
Bone Mineral Density by Age Group of ALL Survivors
Using bone mineral density Z-score, assess relationship between predisposing factors (age groups) and bone mineral density; a negative value indicates a deficit in bone mineral density.
Baseline
Secondary Outcomes (6)
Quantitative Computed Tomography (QCT) and Dual Energy X-ray Absorptiometry (DXA) Scan Scores for Bone Mineral Density.
