Doxercalciferol Before Surgery in Treating Localized Prostate Cancer
Summary
RATIONALE: Doxercalciferol may be an effective way to treat localized prostate cancer before surgery.
PURPOSE: Randomized phase II trial to study the effectiveness of giving doxercalciferol before surgery in treating patients who have localized prostate cancer.
Description
OBJECTIVES:
- Determine whether doxercalciferol modulates intermediate endpoint biomarkers in the development of prostate cancer in patients with localized prostate cancer.
- Assess the toxicity of this drug in these patients.
OUTLINE: This is a randomized, open-label, multicenter study. Patients are randomized to 1 of 2 arms.
- Arm I: Patients receive doxercalciferol once daily for 28 days. Patients then undergo prostatectomy.
- Arm II: Patients undergo observation for 28 days. Patients then undergo prostatectomy.
PROJECTED ACCRUAL: A total of 60 patients (30 per arm) will be accrued for this study within 18 months.

Medical and Biotech [MESH] Definitions
Prostate-specific Antigen
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
Fenretinide
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Ultrasound, High-intensity Focused, Transrectal
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Prostatic Secretory Proteins
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Prostatic Neoplasms
Tumors or cancer of the PROSTATE.
