Official title
Phase 2 Study of High Dose-Rate Brachytherapy and Stereotactic Body Radiotherapy for Intermediate and High Risk Localized Prostate Adenocarcinoma (HYDRA)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
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.
