Summary: 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.

Detailed description: OBJECTIVES: Primary - 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. Secondary - 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.
