3-Dimensional Conformal Radiation Therapy in Treating Patients With Bladder Cancer Who Have Undergone Transurethral Resection of the Bladder

RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. 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.

PURPOSE: This phase I trial is studying the side effects and best dose of 3-dimensional conformal radiation therapy in treating patients with bladder cancer who have undergone transurethral resection of the bladder.

Condition Intervention Phase
Bladder Cancer Procedure: diagnostic cystoscopy Procedure: diffusion-weighted magnetic resonance imaging Procedure: implanted fiducial-based imaging Procedure: quality-of-life assessment Radiation: 3-dimensional conformal radiation therapy Radiation: image-guided radiation therapy Radiation: selective external radiation therapy Phase 1

Study Type: Interventional
Study Design: Masking: Open Label
Primary Purpose: Treatment
Official Title: Image Guided Dose Escalated Adaptive Bladder Radiotherapy

Secondary Outcome Measures:
  • Progression-free survival
  • Overall survival
  • Bladder preservation rates
  • Acute and late toxicity and safety profile
  • Quality of life
  • Tumor boost volumes delineated with and without gold seeds
  • Dose-volume histogram analysis of PTV2 and PTV3 coverage

Estimated Enrollment: 60
Study Start Date: May 2009
Estimated Primary Completion Date: April 2016 (Final data collection date for primary outcome measure)
Detailed Description:



  • To determine the maximum-tolerated dose of external-beam radiotherapy delivered as a tumor boost in patients who have undergone prior transurethral bladder resection for muscle-invasive carcinoma of the bladder.


  • To document progression-free survival and overall survival of these patients.
  • To evaluate patterns of recurrence and bladder preservation rates following dose-escalated radiotherapy in these patients.
  • To determine the impact of acute and late toxicity on quality of life in these patients.
  • To assess the use of gold seeds for tumor boost delineation in these patients.
  • To evaluate the use of virtual cystoscopy tumor localization in these patients.
  • To assess coverage of the phase II radiotherapy boost volume on the daily cone-beam images.
  • To assess coverage of the phase III radiotherapy volume on cone-beam images with selected adaptive strategy.
  • To evaluate the use of diffusion-weighted MRI (dwMRI) scans in assessing response to radiotherapy.

OUTLINE: This is a dose-escalation study.

Patients undergo a rigid cystoscopy and gold-seed insertion, if clinically appropriate. Approximately 3-5 seeds are inserted into the bladder wall to demarcate the maximum extent of visible tumor or tumor bed via a customized introducer. All patients undergo 3-dimensional conformal radiotherapy once daily, 5 days per week during weeks 1 and 4-7 and once daily, 4-6 days per week during weeks 2 and 3, using a combination of image-guided radiotherapy techniques and a partial bladder radiotherapy boost.

Patients complete quality-of-life questionnaire QOL-30 at baseline, 1 and 3 months, and then annually after completion of study treatment.

After completion of study treatment, patients are followed up at 4, 8, and 12 weeks, every 6 months for 3 years, and then annually for 2 years.
