- Patient must provide study specific informed consent prior to study entry
- Patient must have a Gynecologic Oncology Group (GOG) performance status of 0, 1, or 2 or equivalent
- Absolute neutrophil count > 1,500/uL
- Platelets > 100,000/uL
- Hemoglobin > 10 g/dL
- Total bilirubin < 2.0 mg/dL
- Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) < 2.5 X institutional upper limit of normal
- Prothrombin time (PT)/activated partial thromboplastin time (aPTT) < 1.5 X institutional upper limit of normal
- Creatinine =< 1.5 mg/dL to receive weekly cisplatin * Patients whose serum creatinine is between 1.5 and 1.9 mg/dL are eligible for cisplatin if the estimated creatinine clearance (CCr) is >= 30 ml/min; for the purpose of estimating the CCr, the formula of Cockcroft and Gault for females should be used
- Patient does not have uncontrolled diabetes mellitus (i.e., fasting blood glucose > 200 mg/dL)
- Patient has a life expectancy of greater than 20 weeks
- Patient does not have known brain metastases (testing optional)
- Patient does not have known human immunodeficiency virus syndrome (HIV, testing optional); known HIV-positive patients receiving combination antiretroviral therapy are ineligible because of the potential for pharmacokinetic interactions with triapine
- Patient does not have a known allergy to compounds of similar or biologic composition as triapine
- Patient does not have known glucose‐6‐phosphate dehydrogenase (G6PD) deficiency as the condition interferes with triapine antidote metabolism (G6PD testing optional)
- Patient is not actively breastfeeding (or has agreed to discontinue breastfeeding before the initiation of protocol therapy)
- Patient has another concurrent active invasive malignancy
- Patient has had a prior invasive malignancy diagnosed within the last three years (except  non-melanoma skin cancer or  prior in situ carcinoma of the cervix); patients are excluded if they have received prior pelvic radiotherapy for any reason that would contribute radiation dose that would exceed tolerance of normal tissues at the discretion of the treating physician
- Patient has uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within six months of protocol initiation, cardiac arrhythmia within six months of protocol initiation; known inadequately controlled hypertension; clinically significant pulmonary disease including dyspnea at rest, or patients requiring supplemental oxygen, or poor pulmonary reserve; or clinically significant renal function impairment (baseline serum creatinine > 2 mg/dL); or psychiatric illness/social situations that would limit compliance with study requirements
- Patient is receiving another investigational agent for the treatment of cancer
- Patient is currently pregnant
- Patient does not agree to use two forms of birth control if they are of child-bearing potential
- Patients who have had a hysterectomy or are planning to have an adjuvant hysterectomy following radiation as part of their cervical cancer treatment are ineligible (05/30/2017)
- Patients scheduled to be treated with adjuvant consolidation chemotherapy or other anti-neoplastic therapy at the conclusion of their standard chemoradiation (05/30/2017)
- Patients with self-reported or known diagnosis of G6PD deficiency (05/30/2017)
- Patients with vaginal cancer may have previously undergone a hysterectomy for various indications; patients with vaginal cancer who underwent a hysterectomy for treatment of cervical cancer less than five years prior to their diagnosis of vaginal cancer are ineligible

I. To evaluate the efficacy of the experimental regimen of triapine (3AP), cisplatin, and radiation to increase overall survival relative to the standard/control regimen of cisplatin and radiation in women with uterine cervix or vaginal cancer.
I. To determine the relative progression-free survival impact of triapine-cisplatin radio-chemotherapy and cisplatin radio-chemotherapy.
I. To evaluate incidence and severity of hematologic and gastrointestinal (GI) adverse events by radiation modality; image guided intensity modulated radiation therapy (IG-IMRT) versus conventional pelvic radiotherapy. (05/30/2017)
II. To summarize and compare differences in acute adverse events (Common Terminology Criteria for Adverse Events [CTCAE], version [v]4.0) by treatment arm and by radiation modality. (05/30/2017)
III. To summarize and compare differences in chronic or late (>= 30-days from off study treatment date) adverse events (CTCAE, v4.0) by treatment arm and by radiation modality. (05/30/2017)
IV. To determine peripheral blood methemoglobin proportion before and after triapine infusion (optional for Arm 2 patients).
V. To 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.
VI. To determine the post-therapy 3-month fludeoxyglucose F-18 (18F-FDG) PET/CT metabolic complete response rate by treatment arm
VII. To compare acute toxicity and chemotherapy delivery for atlas-based IG-IMRT vs. positron emission tomography (PET)/computed tomography (CT)-based IG-IMRT vs. conventional radiation therapy (RT), and assess the impact of treatment on changes in hematopoietic compensatory response.
VIII. To develop and validate machine learning and radiomics techniques for dose accumulation, automated treatment planning, and prediction of treatment response.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive cisplatin intravenously (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 external beam radiation therapy (EBRT) (either conventional RT or intensity modulated radiation therapy [IMRT]) once daily (QD) 5 days a week for 25 fractions followed by low dose rate (LDR) or high dose rate (HDR) brachytherapy according to institution's standards. Treatment continues in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive cisplatin and undergo EBRT followed by brachytherapy as in Arm I. Patients also receive triapine IV over 2 hours on days 1, 3, 5, 8, 10, 12, 15, 17, 19, 22, 24, 26, 29, 31, and 33. Treatment continues in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 1 and 3 months, every 3 months for 2 years, and then every 6 months for 3 years.
The patient data from NCI #9434 will be merged with NRG-GY006 per the Protocol Analysis Plan.
