RATIONALE: Drugs used in chemotherapy, such as fluorouracil, cisplatin, and gemcitabine,
work in different ways to stop the growth of tumor cells, either by killing the cells or by
stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells.
Giving chemotherapy together with radiation therapy may kill more tumor cells.
PURPOSE: This randomized phase II trial is studying two different chemotherapy and radiation
therapy regimens to see how they work in treating patients with stage II or stage III
bladder cancer that was removed by surgery.
