Summary
Brief summary (as posted)
This phase II trial investigates the effect of high dose-rate brachytherapy and stereotactic body radiotherapy in treating patients with prostate adenocarcinoma. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue.

Arms (1)
- type
- EXPERIMENTAL
- label
- Treatment (HDR-BT, SBRT)
- description
- Patients undergo HDR-BT for up to 24 hours and undergo SBRT every other day or consecutive days for up to 14 consecutive chronologic days in the absence of disease progression or unacceptable toxicity.
- interventionNames
- Radiation: High-Dose Rate Brachytherapy
- Radiation: Stereotactic Body Radiation Therapy
Primary outcomes (2)
- measure
- Biochemical failure
- timeFrame
- Up to 5 years
- description
- Will be based on Phoenix criteria (either a rise of 2 ng/mL or more above nadir prostate specific antigen \[PSA\], or patients not meeting this criterion but underwent salvage therapies). The biochemical progression free survival (b-PFS) will be defined from the date of completing radiotherapy to the date biochemical failure, death, or last follow-up, stratified by prostate cancer risk classification. Kaplan-Meier method will be used.
