Bladder and Bone Effects of Pelvic Radiation Therapy in Childhood Cancer Survivors
- Conditions
- Childhood CancerCancer
- Registration Number
- NCT05818462
- Lead Sponsor
- University of Colorado, Denver
- Brief Summary
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.
- 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.
Recruitment & Eligibility

- 60
- 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.
- Patients with known dysfunctional voiding prior to cancer treatment.
- Patients with tumor resection of bladder, prostate or gynecologic organs will be excluded.

- Primary Outcome Measures
Name Time Method Uroflow and Bladder Scan Results 1.5 years 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)
- Secondary Outcome Measures
Name Time Method DEXA Scan Results 1.5 years 3. Average pelvic and sacral spine bone mineral density Z-scores, as determined by a DEXA scan of pelvis and sacral spine.
DVSS Scores 1.5 years 2. 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.
Number of Patients with Osteoporosis 1.5 years 4. 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
