This phase II trial is studying how triapine and cisplatin given together with radiation therapy works in treating patients with cervical cancer or vaginal cancer. Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as cisplatin, 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. Giving triapine together with cisplatin may make tumor cells more sensitive to radiation therapy.
PRIMARY OBJECTIVES: I. To determine three-month fasting F-18 fluorodeoxyglucose (FDG) positron emission tomography (PET/CT) imaging complete metabolic response as defined by the European Organization for Research and Treatment of Cancer (EORTC) PET study group. SECONDARY OBJECTIVES: I. To determine 6-month progression-free survival rate as calculated from the date of first treatment until date of disease progression, relapse, or death. II. To quantitate change in pre-treatment standard uptake value (SUV) on PET/CT and post-treatment PET/CT or disease progression PET/CT. III. To quantitate pre-treatment, during treatment and 3-mo post-treatment grade 2 or higher gastrointestinal, genitourinary, and sexual function toxicity resulting from Triapine®, cisplatin, and radiation therapy as measured by CTCAE v3.0, which will be utilized until December 31, 2010; CTCAE v4.0 will be utilized beginning January 1, 2011. IV. To associate smoking habit (non-smoker, smoker who quit during therapy, smoker) with 3-mo post-treatment PET/CT metabolic response and 3-mo best overall clinical response as measured by RECIST criteria after Triapine®, cisplatin, and radiation therapy. V. To associate HPV or non-HPV sub-type cervical cancer with 3-mo post-treatment PET/CT metabolic response and 3-mo best overall clinical response as measured by RECIST criteria after Triapine®, cisplatin, and radiation therapy. OUTLINE: This is a multicenter study. Patients are stratified according to brachytherapy treatment (planned intracavitary brachytherapy vs none). Patients receive cisplatin IV over 90 minutes on days 2, 9, 16, 23, and 30 and triapine IV on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29, 31, and 33. Patients also undergo pelvic external beam radiotherapy 5 days a week during weeks 1-5. Patients may undergo parametrial boost radiation and intracavitary low-dose or high-dose rate brachytherapy as clinically indicated. Patients undergo whole-body F-18 fluorodeoxyglucose-PET/CT imaging at baseline, at 3 months after completion of study treatment, and at disease progression. Patients complete Sexual Function-Vaginal Changes Questionnaire and a smoking behavior questionnaire at baseline, at 3 months after completion of study treatment, and at disease progression. After completion of study treatment, patients are followed periodically for up to 5 years.

Fasting F-18 Fluorodeoxyglucose (FDG) Positron Emission Tomography (PET/CT) Imaging Complete Metabolic Response, Reported Following National Cancer Institute (NCI) and European Organization for Research and Treatment of Cancer (EORTC) Guidelines.
To quantitate change in pre-treatment standard uptake value (SUV) on PET/CT and posttreatment PET/CT or disease progression PET/CT. Change in PET/CT SUV will be associated with 3-month best overall clinical response.
Time frame: post therapy at 3 months
Clinical and Objective Response Assignment
Number of patients with a complete clinical responses defined as disappearance of all target lesions. A complete metabolic response on PET/CT will be defined as absence of abnormal FDG uptake at sites of abnormal FDG uptake noted on pre-treatment FDG-PET study.
Time frame: post therapy at 3 months
Clinical and Objective Response Assignment
Number of patients with a complete clinical responses defined as disappearance of all target lesions. A complete metabolic response on PET/CT will be defined as absence of abnormal FDG uptake at sites of abnormal FDG uptake noted on pre-treatment FDG-PET study.
Time frame: one month follow up assessment

Percent of Patients With Incidence of Grade 2 or Higher Gastrointestinal and Genitourinary Toxicity, Assessed Using CTCAE v3.0 Until December 31, 2010 and CTCAE v4.0 Beginning January 1, 2011
Information will include the type, severity, time of onset, time of resolution, and the probable association with the study regimen. Frequency tables will be constructed to summarize observed incidence by severity and type of toxicity.
Time frame: After 5 weeks of radiation therapy
Progression-free Survival
Percentage of patients that did not have disease progression. Estimates of progression-free survival will be computed using the product-limit estimate of Kaplan and Meier.

PET/CT Scan Metabolic Activity
Descriptive tabular data reporting mean, standard deviation, minimum, maximum provided by metabolic response cohort. Status of 3-month post-treatment metabolic response associated with clinical response measured by RECIST criteria and with overall clinical outcome. Kaplan-Meier (product-limit) method of survival estimation used. Tests of equivalence of the estimates compared using the Wilcoxon long-rank test using P 0.05. Cox proportional hazards regression models used in multivariate analyses.
