Magnetic Resonance Imaging-Based Radiation Therapy and Cisplatin in Patients With Stage I, Stage II, Stage III, or Stage IV Cervical Cancer

PURPOSE: This clinical trial is studying magnetic resonance imaging-based radiation therapy and cisplatin in treating patients with stage I, stage II, stage III, or stage IV cervical cancer.Detailed DescriptionPRIMARY OBJECTIVES: I. To evaluate the feasibility of using MRI based treatment planning for intracavitary brachytherapy treatment planning. SECONDARY OBJECTIVES: I. To evaluate the incidence of early toxicities, specifically genitourinary and gastrointestinal. II. To evaluate the incidence of late toxicities, specifically genitourinary and gastrointestinal. III. To evaluate local, regional, and distant recurrence rates. IV. To evaluate disease-free and overall survival rates. OUTLINE: Patients undergo external beam radiotherapy (3-dimensional conformal OR intensity-modulated) and 4-6 insertions of MRI-guided intracavitary brachytherapy over 8 weeks. Patients also receive cisplatin IV over 30-60 minutes for 5-6 weeks during radiotherapy. After completion of study treatment, patients are followed at 6 weeks, every 4 months for 2 years, and then every 6 months for 3 years.
