Trial summary

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Having a full bladder may improve the effectiveness of radiation therapy to the bladder. Read more about this study

About this study

Official title: A Randomised Trial Comparing The Bladder Volume Consistency Achieved With Two Bladder-Filling Protocols in Prostate Conformal Radiotherapy

RATIONALE: Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Having a full bladder may improve the effectiveness of radiation therapy to the bladder. It is not yet known which set of bladder-filling instructions is more effective in helping patients keep their bladder full during radiation therapy.

PURPOSE: This randomized clinical trial is comparing two sets of bladder-filling instructions in treating patients with prostate cancer undergoing radiation therapy.

Read the detailed description

OBJECTIVES:

Primary

  • To compare the consistency in bladder volumes in patients with prostate cancer undergoing conformal radiotherapy, when randomized to one of two sets of bladder-filling instructions.

Secondary

  • To compare the incidence of acute and late genitourinary and gastrointestinal toxicity in patients treated with these methods.
  • To determine patient satisfaction with the bladder-filling instructions.
  • To determine satisfaction of bladder-filling protocols amongst radiation therapists and doctors.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients empty their bladders and consume 6 cups of water 30 minutes before undergoing radiotherapy. Patients also undergo bladder volume measurements using a bladder volume instrument (BVI) periodically during treatment.
  • Arm II: Patients empty their bladders and consume 3 cups of water 30 minutes before undergoing radiotherapy. Patients also undergo bladder volume measurements using a BVI periodically during treatment.

In both arms, patients follow their bladder filling instructions and then undergo conformal radiation therapy daily for about 8 weeks.

Patients' perception of symptoms, quality of life, and urinary symptoms are assessed periodically by the International Prostate Symptom Score (I-PSS). Patients' satisfaction with the bladder-filling instructions (i.e., ability to comply with the bladder-filling protocol, the number of incidents of wetting accidents, number of incidents of having to repeat the water drinking on the same day due to machine breakdown or the patient's inability to retain the full bladder for the required amount of time, and the level of frustration) is assessed periodically by the Visual Analogue Scale (VAS).

Staff satisfaction with bladder-filling interventions (i.e., patient compliance with the protocols, acceptance of bladder dose-volume histograms [DVHs], need for re-scan with a fuller bladder, amount of disruption to the therapist's work schedule, number of incidents of wetting accidents, number of incidents of having to repeat the water drinking on the same day due to machine breakdown or the patient's inability to retain the full bladder for the required amount of time, and the level of satisfaction or frustration) is assessed periodically.

After completion of study treatment, patients are followed up periodically for 4 years.

Questions about this trial

What is this clinical trial studying?

A study testing pre-procedural preparation in people with Prostate Cancer, run by Cancer Trials Ireland at 1 site in Ireland.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

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: finished, as of the sponsor's last update on 31 Dec 2014. 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 Ireland. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Consistency of bladder volumes (time frame: 2011). 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.

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 31 Dec 2014.
