Radiation Therapy With or Without Carbogen and Niacinamide in Treating Patients With Bladder Cancer

Summary

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.
