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. Combining cisplatin with gemcitabine may make the tumor cells more sensitive to radiation therapy and may kill more tumor cells.
PURPOSE: This phase I trial is studying the side effects and best dose of gemcitabine when given together with radiation therapy and cisplatin in treating patients with cervical cancer that has not spread beyond the pelvis.
- Determine the toxicity of pelvic radiotherapy and concurrent cisplatin and gemcitabine in patients with cervical carcinoma limited to the pelvis.
- Determine the maximum tolerated dose (MTD) of gemcitabine in combination with cisplatin and pelvic radiotherapy in these patients.
- Determine the progression-free and overall survival of patients treated with gemcitabine at the MTD in this regimen.
- Determine the site of recurrence, local versus distant, in patients treated with this regimen.
OUTLINE: This is a multicenter, dose-escalation study of gemcitabine.
Patients receive gemcitabine IV over 30 minutes and cisplatin IV over 1 hour on days 1, 8, 15, 22, 29, and 36 in the absence of disease progression or unacceptable toxicity. Patients also undergo external whole pelvis radiotherapy once daily on days 1-5, 8-13, 15-20, 22-27, and 29-34. After completion of external beam radiotherapy, patients undergo intracavitary radiotherapy and parametrial radiotherapy. The total elapsed time for completion of all radiotherapy is not more than 8 weeks.
Cohorts of 3-6 patients receive escalating doses of gemcitabine until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose at which 1 of 6 patients experiences dose-limiting toxicity.
Patients are followed every 3 months for 2 years and then every 6 months for 3 years.
PROJECTED ACCRUAL: A total of 3-24 patients will be accrued for this study within 1-24 months.

Preliminary cancer therapy (chemotherapy, radiation therapy, hormone/endocrine therapy, immunotherapy, hyperthermia, etc.) that precedes a necessary second modality of treatment.
Drug therapy given to augment or stimulate some other form of treatment such as surgery or radiation therapy. Adjuvant chemotherapy is commonly used in the therapy of cancer and can be administered before or after the primary treatment.
Organs which might be damaged during exposure to a toxin or to some form of therapy. It most frequently refers to healthy organs located in the radiation field during radiation therapy.
Drugs used to protect against ionizing radiation. They are usually of interest for use in radiation therapy but have been considered for other, e.g. military, purposes.
An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
