Summary
Brief summary (as posted)
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Calcitriol may help carboplatin kill more cancer cells by making tumor cells more sensitive to the drug. PURPOSE: Phase II trial to study the effectiveness of carboplatin plus calcitriol in treating patients who have prostate cancer that has not responded to hormone therapy.
