 RATIONALE: Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy in higher doses over a shorter period of time may kill more tumor cells and have fewer side effects. Drugs used in chemotherapy, such as docetaxel, epirubicin, cyclophosphamide, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Giving more than one drug combination chemotherapy together with radiation therapy may kill more tumor cells.
