About this study
The standard options for men with very low risk prostate cancer include active surveillance and the standard treatment options for low risk disease, i.e. radical prostatectomy, external beam radiotherapy, and whole gland prostate brachytherapy. The present study seeks to evaluate focal brachytherapy using the isotope Cesium 131 to treat patients with low risk prostate cancer. The goals of the study are to determine the biochemical disease free survival at five years in these patients, as well as to determine the acute and late urinary, bowel, and sexual toxicity associated with focal prostate brachytherapy using Cesium 131. Patients eligible for the study will be men with histologically confirmed adenocarcinoma of the prostate with clinical stage T1c-T2aN0M0, Gleason score ≤3+3=6, prostate specific antigen(PSA) <10 ng/ml or a PSA density ≤ 0.15 ng/cc, and ≤ 2 cores positive out of a minimum of 12 cores sampled. Additionally, patients must have a single, dominant index lesion on MRI. The study is a phase II study. Patients will be followed prospectively. Dosimetry will be evaluated post-procedure, and PSAs will be obtained every three months in year one and every six months from year two through year five. Urinary, bowel, and sexual morbidity will be assessed by patient survey prior to treatment , two weeks, after treatment, at three month intervals in year one and at six month intervals in years two through five.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
biochemical disease free survival (time frame: five years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
