Radiation Therapy in Treating Patients With Stage II or Stage III Prostate Cancer
RATIONALE: Radiation therapy uses high-energy x-rays and other sources to damage tumor cells. Internal radiation therapy uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving radiation therapy in different ways may kill more tumor cells.
PURPOSE: This phase II trial is studying how well giving internal radiation therapy together with external-beam radiation therapy works in treating patients with stage II or stage III prostate cancer.

- Late Severe Genitourinary (GU) and Gastrointestinal (GI) Toxicity at 18 Months [ Time Frame: Beginning nine months after start of treatment. ]Eighteen-month rate of late severe (grade 3-5) genitourinary (GU) and gastrointestinal (GI) toxicity, defined as starting more than 9 months from treatment start, and graded by CTCAE v3.0
- Acute Severe GU and GI Toxicity as Measured by Common Terminology Criteria for Adverse Events (CTCAE) v3.0 Within 9 Months of Starting Treatment [ Time Frame: From registration until 9 months from the start of treatment ]
- Biochemical Failure [ Time Frame: From registration to the date of biochemical failure or last follow-up. Analysis occurs after each patient has had 3 years of follow-up. ]
- Overall Survival [ Time Frame: From registration to the date of death or last follow-up. Analysis occurs after each patient has had 3 years of follow-up. ]
- Disease-specific Survival [ Time Frame: From registration to the date of death due to prostate cancer or other disease related cause. Analysis occurs after each patient has had 3 years of follow-up. ]
- Clinical Progression Including Local/Regional and Distant Relapse [ Time Frame: From registration to the date of local/regional progression or distant relapse, or last follow-up. Analysis occurs after each patient has had 3 years of follow-up. ]

Experimental: EBRT and HDR brachytherapy boost
External beam radiation therapy (EBRT) and high dose rate (HDR) brachytherapy boost.
Radiation: HDR brachytherapy boost
Brachytherapy could be performed before or after the external beam radiotherapy. The overall treatment course (external beam radiotherapy and brachytherapy) was limited to no longer than 8 weeks. 19 Gy in two fractions was to be given only to the clinical target volume (CTV). The first HDR treatment was to be delivered on the day of the catheter placement. The second treatment was to be delivered within 24 hours after the first treatment, but no less than 6 hours between implants.Radiation: radiation therapy
1.8 Gy given five times per week for a total dose of 45 Gy.
- Determine the rate of late grade 3 or greater genitourinary and gastrointestinal toxicity after treatment with external beam radiotherapy and high-dose rate brachytherapy in patients with stage II or III adenocarcinoma of the prostate.
- Determine acute grade 3 or greater genitourinary and gastrointestinal toxicity in patients treated with this regimen.
- Determine freedom from biochemical failure in patients treated with this regimen.
- Determine overall survival of patients treated with this regimen.
- Determine disease-specific survival of patients treated with this regimen.
- Determine clinical relapse (local and/or distant) in patients treated with this regimen.
- Develop a quality assurance process for high-dose rate prostate brachytherapy.
OUTLINE: This is a multicenter study. Patients are stratified according to prostate-specific antigen (≤ 10 ng/mL vs 11-20 ng/mL), T stage (T1c-T2c vs T3a-T3b), combined Gleason score (2-6 vs 7 vs 8-10), prior hormonal therapy (no vs yes), and timing of high-dose rate brachytherapy (before external beam radiotherapy vs after external beam radiotherapy).
Patients undergo external beam radiotherapy over approximately 15 minutes once daily 5 days a week for 5 weeks. Patients also receive two fractions (within a 24-hour period) of high-dose rate brachytherapy (delivered through an implant inserted into the prostate) over approximately 5-30 minutes either before or after external beam radiotherapy. Treatment continues in the absence of disease progression or unacceptable toxicity.
Patients are followed at 3, 7, 9, and 12 months, every 6 months for 5 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 110 patients will be accrued for this study within 1 year.
