Focal Radiotherapy for Previously Treated Prostate Cancer Patients
Phase I Feasibility Trial of Stereotactic Re-irradiation of Prostate Cancer Recurrence Within the Definitively Irradiated Prostate
About This Trial
- This study is testing whether a precise, highly targeted type of radiation is safe and effective for treating prostate cancer that has returned.
- It is open to men whose cancer has come back in only a small, specific part of the prostate several years after receiving their first radiation treatment.
- To qualify, you must have scans and a biopsy confirming the cancer is limited to a single area, as well as a PSA level under 10.
- Before joining, patients should know that the procedure requires placing tiny guidance markers in the prostate and is not suitable for those who experienced severe side effects from their past radiation treatments.
More Information
- To examine the feasibility, safety and toxicity of focal stereotactic radiation treatment (SBRT) for locally recurrent prostate cancer.
Who Can Enroll
- Age Range: 18 years and older
- Gender: Male
- Who This Trial is For: This study is testing whether a precise, highly targeted type of radiation is safe and effective for treating prostate cancer that has returned.
