Tumor Perfusion and Hypoxia Assessed by DCE-MRI and 18F-FMISO PET as Biomarkers of Treatment Response in Cervical Cancer
This study is to assess how patients respond to their treatment for cervical cancer. This research does not involve a specific treatment for the cancer that will be recommended by the doctor and may include radiation therapy and/or chemotherapy. This is a separate research imaging study designed to assess how patients respond to their treatment for cervical cancer.

- predict tumor response [ Time Frame: 2 years ] [ Designated as safety issue: No ]For each DCE-MRI parameter, the relative percent change from baseline to the two-week measurement will be calculated. These values will be assessed using ROC curves to evaluate whether they are predictive of tumor response.
- predict disease-free survival [ Time Frame: 2 years ] [ Designated as safety issue: No ]baseline tumor perfusion parameters are predictive of disease-free survival at 2 years and 5 years, the primary analysis will again be an ROC analysis, but with the ROC curves modified to take into account the censored failure-outcome. We will create time-dependent ROC curves using methods described by Heagerty et al.

Experimental: DCE-MRI and 18F-FMISO PET
Each patient will undergo three DCE-MRI (dynamic contrast-enhanced MRI) studies: a baseline DCE-MRI within two weeks before chemoradiation; a second DCE-MRI after the second week of treatment (within a week); and a third DCE-MRI three months after treatment. As a pilot study in 10 patients, we will perform 18F-FMISO PET/CT on the same day of a baseline DCE-MRI before chemoradiation. Treatment decisions will not be based on DCE-MRI and 18F-FMISO PET/CT studies.
Other: DCE-MRI and 18F-FMISO PET
DCE-MRIs: (i) Baseline DCE-MRI within two weeks before chemoradiation; (ii) Second DCE-MRI after the second week of chemoradiation (within a week); (iii) Third DCE-MRI three months after chemoradiation. iii. 18F-FMISO PET: Baseline 18F-FMISO PET within two weeks before chemoradiation (only 10 patients as a pilot study). iv. Clinical Follow-up: (i) Physical examination (every 3 months); (ii) Pap smear or cervical biopsy (every 3 months); (iii) follow-up imaging studies (CT and/or MRI) as per routine clinical follow-up of patients.
