Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 2 to 40 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: Cohort 1: Childhood cancer survivors who were treated with chemotherapy and radiation therapy to the pelvis, with or without surgical intervention. This group will consist of both primary pelvic sarcomas as well as patients who received whole abdominal radiation that included bladder exposure. Cohort 2: Childhood cancer survivors who have been treated for a sarcoma who did not receive pelvic radiation, and were treated with chemotherapy, with or without surgical intervention or radiation therapy (outside of the pelvis). These patients will be matched as closely as possible to Group 1 to match chemotherapy regimens, and sex.

Who may be able to join

  • Patients of any age who were treated were diagnosed in 2007 or later and received chemotherapy for solid tumor malignancy, with completion of therapy (whether chemotherapy or radiation) at least one year prior to study enrollment.

Who cannot join

  • Patients with known dysfunctional voiding prior to cancer treatment.
  • Patients with tumor resection of bladder, prostate or gynecologic organs will be excluded.

About this study

Official title: Effect of Pelvic Radiation Therapy on the Urinary and Musculoskeletal Systems of Survivors of Childhood Cancer

The aim of this study is to measure and evaluate the effects of pelvic external beam radiation therapy (EBRT) on lower urinary tract (LUT) function and bone mineralization.

Read the detailed description

The aim of this study is to measure and evaluate the effects of pelvic external beam radiation therapy (EBRT) on lower urinary tract (LUT) function and bone mineralization. The overarching hypothesis is that patients who received EBRT to the pelvis will have an increased rate of LUT dysfunction and osteoporosis even when controlled for chemotherapeutic exposures, using patients with similar chemotherapy regimens as controls. Between these two groups, the team expect to observe significant differences in both patient-reported outcomes and direct measures of LUT function.

Being tested
Uroflow testing, Bladder Scan, Dysfunctional Voiding Scoring System Survey, DEXA Scan of pelvis and sacral spine, Urine tests for specific biomarkers

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Uroflow testingDiagnostic test

    Uroflowmetry is a test that measures the volume of urine released from the body, the speed with which it is released, and how long the release takes.

  • Bladder ScanDiagnostic test

    Bladder scan measures ultrasonic reflections within the patient's body to differentiate the urinary bladder from the surrounding tissue. In this case, it is used to detect the volume of urine in the bladder.

  • Dysfunctional Voiding Scoring System SurveyOther

    The Dysfunctional Voiding Symptom Score to provide accurate and objective numerical, grading of voiding behaviors of children.

  • DEXA Scan of pelvis and sacral spineDiagnostic test

    DEXA (dual x-ray absorptiometry) scans measure bone density (thickness and strength of bones) by passing a high and low energy x-ray beam (a form of ionizing radiation) through the body, usually in the hip and the spine.

  • Urine tests for specific biomarkersDiagnostic test

    Urine tests for specific biomarkers (ATP, NGF, BNDF and urine proteomic screening).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Uroflow and Bladder Scan Results

    aggregate measured by voiding time (seconds, s), total voided volume (mL), average uroflow rate (mL/s), maximum uroflow rate (mL/s), uroflow pattern or curve (bell-shaped, tower-shaped, staccato, interrupted or plateau), and post void residual (mL)

    Measured: 1.5 years

Secondary outcomes (3)
  1. DVSS Scores

    1. Total DVSS survey scores to determine patient-reported urinary symptom. Gender-specific DVSS total score thresholds: males ≥9, females ≥6. Minimum DVSS score is 0 points. Maximum DVSS score is 30 points.

    Measured: 1.5 years

  2. Number of Patients with Osteoporosis

    1. Rates of osteopenia and osteoporosis, as determined by bone density Z-score using DEXA scan of pelvis and sacral spine. Osteopenia is defined as a z-score between - 1 to -2.5, while osteoporosis is defined as a z-score below -2.5

    Measured: 1.5 years

  3. DEXA Scan Results

    1. Average pelvic and sacral spine bone mineral density Z-scores, as determined by a DEXA scan of pelvis and sacral spine.

    Measured: 1.5 years

Questions about this trial

What is this clinical trial studying?

An observational study of Cancer and Childhood Cancer, run by University of Colorado, Denver at 1 site in United States.

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 1 inclusion and 2 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: finished, 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 United States. 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?

Uroflow and Bladder Scan Results (time frame: 1.5 years). 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 NCT05818462, which also lists 1 linked publication.

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.
