About this trial

This is an interventional treatment trial for Prostate Cancer focused on measuring adenocarcinoma of the prostate, recurrent prostate cancer

Eligibility Criteria

5. Study Description

Brief Summary
RATIONALE: Calcitriol, a form of vitamin D, may be able to prevent or slow the growth of prostate cancer cells. PURPOSE: Phase II trial to study the effectiveness of calcitriol in treating patients who have a rising PSA level following previous treatment for prostate cancer.
Detailed Description
OBJECTIVES: I. Determine the response to pulse calcitriol in patients with previously treated adenocarcinoma of the prostate with rising PSA levels. II. Assess the impact of this regimen on the slope of the PSA rise in these patients. III. Determine the qualitative and quantitative toxic effects of this regimen in these patients. IV. Assess the impact of this regimen on the quality of life of these patients. OUTLINE: All patients remain on a reduced calcium diet for the duration of the study. Twelve hours prior to treatment, patients begin drinking 4-6 glasses of extra fluid for 3 days. Patients receive oral calcitriol over 4 hours weekly. Treatment continues in the absence of disease progression or unacceptable toxicity. Quality of life is assessed at baseline, every 4 weeks during treatment, and at the end of the study. Patients are followed for at least 1 month. PROJECTED ACCRUAL: A total of 15-25 patients will be accrued for this study.
