RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs such as carbogen and niacinamide may make tumor cells more sensitive to radiation therapy. It is not yet known whether radiation therapy is more effective with or without carbogen and niacinamide in treating patients who have bladder cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of radiation therapy with or without carbogen and niacinamide in treating patients who have locally advanced bladder cancer.
|Condition or disease||Intervention/treatment||Phase|
|Bladder Cancer||Dietary Supplement: niacinamide Drug: carbogen Radiation: radiation therapy||Phase 3|
- Compare the 6-month cystoscopic response in patients with locally advanced transitional cell carcinoma of the bladder treated with radical radiotherapy with or without radiosensitization with carbogen and niacinamide.
- Compare the local failure-free and overall disease-specific survival of patients treated with these regimens.
- Compare the treatment-related morbidity, in particular acute and chronic bowel and bladder symptoms, in patients treated with these regimens.
- Compare the quality of life of patients treated with these regimens.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to 1 of 2 treatment arms.
- Arm I: Patients receive radical radiotherapy once daily, 5 days a week, for 4-6.4 weeks. Patients also receive oral niacinamide once daily 1.5-2 hours before initiation of each radiotherapy dose and carbogen through a closed breathing system (face mask with a tight air seal or a mouthpiece with nasal clip) once daily beginning 5 minutes before initiation and continuing until completion of each radiotherapy dose.
- Arm II: Patients receive radiotherapy as in arm I. Quality of life is assessed at baseline; at 4 weeks; at 3, 6, and 12 months; and then annually for 4 years.
Patients are followed at 8 and 12 weeks; at 6, 9, and 12 months; and then every 6 months for 4 years.

PROJECTED ACCRUAL: A total of 330 patients (165 per treatment arm) will be accrued for this study.
