Brief Summary:
This randomized phase III trial studies radiation therapy and cisplatin with triapine to see how well they work compared to the standard radiation therapy and cisplatin alone in treating patients with newly diagnosed stage IB2, II, or IIIB-IVA cervical cancer or stage II-IVA vaginal cancer. Radiation therapy uses high energy protons to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as cisplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Triapine may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether radiation therapy and cisplatin are more effective with triapine in treating cervical or vaginal cancer.

Active Comparator: Arm I (cisplatin, IMRT or RT, brachytherapy)
Patients receive cisplatin IV over 90 minutes on days 2, 9, 16, 23, 30, (and day 36 or 37 at the treating physician's discretion). Patients then undergo EBRT (either conventional RT or IMRT) QD 5 days a week for 25 fractions followed by LDR or HDR brachytherapy according to institution's standards. Treatment continues in the absence of disease progression or unacceptable toxicity.

Primary Outcome Measures :
- Progression-free survival (PFS) [ Time Frame: Time (in months) since registration (and randomization) onto the study to the date of first documented recurrence/progression, death or last follow-up visit (contact), assessed up to 5 years ]Product-limit estimates according to the method of Kaplan and Meier and the one sided log-rank test (alpha = 0.1) will be used to compare survival endpoint (PFS) between treatment arms. In addition, adjusted hazard ratios and respective 95% confidence intervals will be calculated using the Cox proportional hazards regression model.
Secondary Outcome Measures :
- Overall survival (OS) [ Time Frame: Time (in months) since registration (and randomization) onto the study to the date death or last contact, assessed up to 5 years ]Product-limit estimates according to the method of Kaplan and Meier and the one sided log-rank test (alpha = 0.1) will be used to compare survival endpoint (OS) between treatment arms. In addition, adjusted hazard ratios and respective 95% confidence intervals will be calculated using the Cox proportional hazards regression model.
- Metabolic complete response (mCR) [ Time Frame: Up to 3 months after completion of treatment ]Will be assessed by fludeoxyglucose F-18 (18F-FDG) positron emission tomography (PET)/computed tomography (CT). Frequency of mCR will be tabulated and the probability of attaining a mCR will be estimated. Differences in mCR rate between treatment arms will be assessed using either the Chi-square or Fisher's exact test. The relationship between patients' mCR status at T1 (yes or no) and PFS (and/or OS) will be assessed using regression models to facilitate evaluation of mCR as secondary short term endpoint for patient outcome.
- Incidence of acute adverse events [ Time Frame: Up to 30 days after completion of study treatment ]Will be assessed by Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The frequency and severity of adverse events will be assessed. Maximum grade of adverse effect will be tabulated for each adverse event and significance of observed differences between treatments arms within each adverse event category will be assessed using Chi-square or Fishers' exact test.
- Treatment compliance (amount of radiation, cisplatin and triapine administered, incidence and duration of treatment delays, reason for delays, and reason why off study therapy) [ Time Frame: Up to 5 years ]Treatment compliance will be evaluated and reported.
- Incidence of hematologic and gastrointestinal (GI) adverse events [ Time Frame: Up to 30 days after completion of study treatment ]Will be assessed by CTCAE version 4. The frequency and severity of adverse events will be assessed. Maximum grade of adverse effect will be tabulated for each adverse event and significance of observed differences between treatments arms within each adverse event category will be assessed using Chi-square or Fishers' exact test.
- Incidence of chronic or late adverse events [ Time Frame: Up to 5 years ]Will be assessed by CTACE version 4. The frequency and severity of adverse events will be assessed. Maximum grade of adverse effect will be tabulated for each adverse event and significance of observed differences between treatments arms within each adverse event category will be assessed using Chi-square or Fishers' exact test.
Other Outcome Measures:
- Changes in the proportion of peripheral blood methemoglobin [ Time Frame: Baseline to 24 hours after triapine infusion ]Difference in peak or in trend of blood methemoglobin levels before and after triapine infusion will be assessed using two tailed paired T-test at alpha = 0.05 significance level. Depending on the observed within subjects correlation, repeated measures analysis of variance may be utilized instead.
- Type of intensity modulated radiation therapy (IG-IMRT) [ Time Frame: Up to 5 years ]Will explore whether knowledge-based planning (KBP) can improve IG-IMRT plans compared to plans that would have been delivered without KBP, estimate the resulting toxicity reduction using normal tissue complication probability (NTCP) models, and determine whether KBP should be a requirement for future IG-IMRT protocols
