Outcomes
Primary Outcome Measures
Pattern of Response of Serum 25(OH) D3 Levels
Change from Baseline in Serum 25(OH) D3 Levels at 1, 3, and 6 Months at dose levels 4000, 6000, 8000 and 10000 IU. Statistical analysis was done using one sample t-test.

Toxicity
Number of treated patients that had serious adverse events.
Occurrence of Infections, Deep Vein Thrombosis, Vascular Events, and Falls
Number of participant with occurrence of infections, deep venous thrombosis, vascular events and falls

5. Study Description
Brief Summary
RATIONALE: Vitamin D may be effective in treating patients with prostate cancer.
PURPOSE: This randomized phase II trial is studying how well 4 different doses of vitamin D works in treating patients with prostate cancer.
Detailed Description
OBJECTIVES:
Primary
To examine the pattern of response of serum 25(OH) D3 levels following cholecalciferol (vitamin D3) supplementation at four different oral doses in patients with prostate cancer.
Secondary
To examine the pattern of response of parathormone (PTH) following vitamin D3 supplementation in these patients.
To assess the toxicity of vitamin D3 supplementation in men with prostate cancer.
Tertiary
To track occurrence of infections, deep vein thrombosis, vascular events, and falls in these patients.
OUTLINE: Patients are randomized to 1 of 4 treatment arms.
Arm I: Patients receive 4,000 IU of oral cholecalciferol (vitamin D3) once daily.
Arm II: Patients receive 6,000 IU of vitamin D3 once daily.
Arm III: Patients receive 8,000 IU of vitamin D3 once daily.
Arm IV: Patients receive 10,000 IU of vitamin D3 once daily. Treatment in all arms continues for 6 months in the absence of disease progression or unacceptable toxicity.
