Radiation Therapy in Treating Patients With Prostate Cancer - Full Text View

Sponsor:	Memorial Sloan-Kettering Cancer Center
Information provided by:	National Cancer Institute (NCI)
ClinicalTrials.gov Identifier:	NCT00002480

Purpose

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:

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.
