Brief Summary:

RATIONALE: Cholecalciferol (vitamin D) may improve quality of life by increasing blood counts, decreasing fatigue, and improving other symptoms of myelodysplastic syndrome.

PURPOSE: This phase II trial is studying how well cholecalciferol works in treating patients with myelodysplastic syndrome.

Condition or disease Intervention/treatment Phase
Leukemia Myelodysplastic Syndromes Myelodysplastic/Myeloproliferative Neoplasms Dietary Supplement: cholecalciferol Phase 2

Detailed Description:


  • Determine the efficacy of cholecalciferol, in terms of hematological improvement, in patients with low- or intermediate-risk myelodysplastic syndromes.
  • Determine the effect of this drug on disease symptoms, fatigue, and the overall health-related quality of life of these patients.

OUTLINE: This is an open-label, pilot study.

Patients receive oral cholecalciferol once daily. Treatment continues for 6 months in the absence of disease progression or unacceptable toxicity.

PROJECTED ACCRUAL: A total of 36 patients will be accrued for this study.
