Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Radiation therapy may be an effective treatment for prostate cancer.

PURPOSE: Phase I trial to study the effectiveness of radiation therapy in treating patients who have stage II or stage III prostate cancer.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

OBJECTIVES: I. Determine the maximum tolerated dose of radiotherapy using 3-dimensional (3D) conformal techniques in patients with stage II or III adenocarcinoma of the prostate. II. Determine the morbidity of high-dose 3D conformal therapy in these patients.

OUTLINE: This is a dose escalation study. Patients undergo 3-dimensional conformal radiotherapy 4-5 days a week for at least 8 weeks. Cohorts of 20-40 patients receive escalating doses of radiotherapy until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which no more than 10% of patients experience dose-limiting toxicity. Patients are followed at 3 months, every 6 months for 5 years, and then annually thereafter.

PROJECTED ACCRUAL: A minimum of 40 patients will be accrued for this study.
