Radiation Therapy Plus Celecoxib, Fluorouracil, and Cisplatin in Patients With Locally Advanced Cervical Cancer

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Giving radiation therapy in different ways and combining it with chemotherapy may kill more tumor cells. Celecoxib may slow the growth of cervical cancer by stopping blood flow to the tumor. PURPOSE: Phase I/II trial to study the effectiveness of radiation therapy plus celecoxib, fluorouracil, and cisplatin in treating patients who have locally advanced cervical cancer.
