Brief summary: RATIONALE: Drugs used in chemotherapy, such as carboplatin, 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. Drugs such as cidofovir may make tumor cells more sensitive to radiation therapy. Giving cidofovir together with radiation therapy and chemotherapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of cidofovir in treating patients with stage IB, stage II, stage III, or stage IVA cervical cancer who are receiving chemotherapy together with radiation therapy.

Detailed description: OBJECTIVES:

Primary

* Determine the maximum tolerated dose of cidofovir when given as a radiosensitizer in patients with stage IB-IVA cervical cancer undergoing concurrent chemoradiotherapy.

Secondary

* Evaluate the influence of treatment on the expression of mRNA codons in HPV oncoproteins E6 and E7.
* Determine the rate of local control.

OUTLINE: This is a dose-escalation study of cidofovir.

Patients receive cidofovir IV weekly for 2 weeks prior to beginning radiotherapy and then once biweekly during radiotherapy. Patients undergo external pelvic radiotherapy for 5 weeks. Beginning ≤ 2 weeks later, patients undergo utero-vaginal brachytherapy. Some patients may also undergo a second course of external radiotherapy to the parametrium and/or lymph nodes ≤ 3 days after brachytherapy. Patients also receive concurrent carboplatin IV once weekly during external radiotherapy and brachytherapy.

Biological expression of HPV oncoproteins E6 and E7 is analyzed during treatment.
