简要总结
RATIONALE: Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells.
PURPOSE: This clinical trial is studying the side effects and how well internal radiation therapy works in treating patients with prostate cancer.
详细描述
OBJECTIVES:
Primary
- To assess the feasibility of high-dose rate (HDR) brachytherapy (without the use of external-beam radiotherapy) as definitive treatment for patients with intermediate-risk prostate cancer.
- To assess acceptable toxicity, defined as treatment related toxicity (urinary and rectal), no worse than that seen by patients treated with conventional therapy (grade 3 urinary toxicity < 10% and grade 3 rectal toxicity < 10%).
Secondary
- To achieve adequate dosimetric coverage of the prostate comparable to current standards.
- To assess the effect of treatment on sexual function.

结局指标
主要结局
Number of Patients With an Acceptable Level of Severe Toxicity as Defined at < Grade 3 CTC Toxicity
时间窗: At scheduled 3 month intervals for one year
Feasibility will be defined as an acceptable level of severe toxicity (both acute and late effects), and adequate dosimetric coverage. Severe toxicity will be defined as \> or = grade 3 NCI CTC toxicity
Number of Patients With an Acceptable Level of Treatment Related Urinary and Rectal Toxicity as Defined at < Grade 3 CTC Toxicity
时间窗: Within 90 days of treatment (early toxicities) or after 90 days (late toxicities)
urinary and rectal toxicity-see the adverse event tables
