About this study
Official title: IMPROVING QUALITY OF LIFE AFTER OPTIMAL RADIOTHERAPY FOR INTERMEDIATE AND HIGH RISK PROSTATE CANCER: A Randomized Comparison of HDR Versus LDR BRACHYTHERAPY BOOST
Optimal non surgical treatment of prostate cancer requires dose escalation which is frequently provided by adding a brachytherapy "boost" to a short course of external beam radiotherapy. The hypothesis in this randomized study is that a High Dose Rate (HDR) brachytherapy boost leads to equivalent or better Prostate Specific Antigen (PSA) recurrence-free survival when compared to a Low Dose Rate (LDR) brachytherapy boost and that it is associated with a more favorable toxicity profile and improved quality of life.
Read the detailed description
Men with intermediate or high risk prostate cancer who are technically suitable for prostate brachytherapy based on prostate size and voiding function and who are interested in this modality of treatment will be approached for randomization between either high dose rate (single 15 Gray) or low dose rate permanent seed implant (110 Gray) brachytherapy. Baseline International Prostate Symptom score, Quality of Life Assessment and International Index of Erectile Function will be recorded and then every 3 months for the first year and every 6 months to 3 years. Androgen deprivation treatment is allowed for 6 or 12 months.

| Study group | Role | What they receive |
|---|---|---|
| LDR boost | Active comparator | After completion of 46 Gy of external beam radiotherapy subjects will undergo a permanent seed radioactive implant to the prostate using iodine-125 seeds to deliver a dose of 110 Gy Receives: Radiation: LDR |
| HDR boost | Active comparator | Subjects in this arm will undergo an HDR implant to deliver 15 Gy to the prostate prior to commencing the external beam component of their treatment. Receives: Radiation: HDR |
What is being measured
The primary outcome is the main question the study is designed to answer.
Compare Quality of Life between two arms as measured by EPIC questionnaire
Quality of life will be measured through validated instruments including International Prostate Symptom Score (IPSS), the International Index of Erectile Function ((IEF), and the urinary, bowel and sexual domains of the Expanded Prostate Cancer Index Composite (EPIC). IPSS has 7 questions related to voiding symptoms, each scored 0-5, with a higher score indicating worse symptoms. IIEF has 5 questions, each scored 0-5 with a higher score indicating better function. EPIC has several questions for each domain with an overall higher score associated with better QoL in that domain.
Measured: 6 months
Secondary outcomes (1)
Quality of Life long term
Quality of Life will be assessed to 5 years using the validated instruments International Prostate Symptom Score, International Index Erectile Function and EPIC
Measured: 5 years

Questions about this trial
What is this clinical trial studying?
A study testing HDR and LDR in people with Prostate Cancer, run by British Columbia Cancer Agency at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 17 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 29 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
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?
Compare Quality of Life between two arms as measured by EPIC questionnaire (time frame: 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01936883, which also lists 7 linked publications.
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.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Jan 2026.
