External-Beam Radiation Therapy Plus Implanted Radiation Therapy in Treating Patients With Prostate Cancer - Full Text View

ClinicalTrials.gov Identifier:	NCT00006365

Purpose

RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Giving radiation therapy in different ways may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of external-beam radiation therapy followed by implanted radiation therapy in treating patients who have prostate cancer.

Detailed Description:

OBJECTIVES: I. Determine the acute and late grade 3-5 genitourinary and gastrointestinal toxic effects of external beam radiotherapy followed by permanent source brachytherapy using interstitial iodine I 125 seeds in patients with intermediate risk, clinically localized adenocarcinoma of the prostate. II. Determine the freedom from PSA failure, overall survival, disease specific survival, and local and/or distant clinical relapse rates in patients treated with this regimen.

OUTLINE: This is a multicenter study. Patients undergo external beam radiotherapy (EBRT) to the pelvis 5 days a week for 5 weeks. Permanent source brachytherapy comprised of ultrasound-guided implantation of iodine I 125 seeds into the prostate is performed 2-6 weeks after completion of EBRT. Patients are followed at 1, 3, 6, 9, and 12 months, then every 6 months for 2 years, and then annually thereafter.

PROJECTED ACCRUAL: A total of 110 patients will be accrued for this study within 1 year.
