Brief Summary
This phase I trial studies the side effects and best dose of triapine when given with radiation therapy and cisplatin in treating patients with stage IB2-IVA cervical or vaginal cancer. Triapine may stop the growth of cancer cells by blocking an enzyme needed for cell growth. Cisplatin is a drug used in chemotherapy that kills cancer cells by damaging their deoxyribonucleic acid (DNA) and stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells and shrink tumors. Adding triapine to standard treatment with cisplatin and radiation therapy may kill more cancer cells.

Outcome Measures
Primary Outcomes (7)
Maximum Tolerated Dose (MTD)
The MTD was determined following a standard 3+3 design is as follows: Escalation at 0/3 DLTs, dose-reduction if \>1/3 DLT, and expansion to 6 if 1/3 DLTs. DLT is defined as the severe toxicity event that leads to the termination of the treatment as defined in section 5.5. The highest dose level where \<2/6 DLTs are observed will be declared MTD
Up to 5 weeks
Number of Patients Who Experienced a DLT
Number of patients that experienced a DLT, evaluated using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0. DLTs are defined as the following adverse events if considered at least "possibly related" to a component of the study therapy and which occur from the start of treatment until completion of EBRT, prior to initiation of brachytherapy (i.e. the first 5 weeks if no treatments are missed): Any nausea, vomiting, diarrhea and elevation of serum creatinine level Grade 3 toxicity not resolved with maximal intervention to Grade 0-2 over 7 days (except alopecia and fatigue); Any nausea, vomiting, diarrhea and elevation of serum creatinine level Grade 4 toxicity; Any other non-hematologic toxicity ≥Grade 3; Any hematologic toxicity of ≥ Grade 4; Grade ≥3 dyspnea; Inability to deliver at least 20 of the scheduled 25 administrations of triapine at the planned dose, allowing for 2 weeks to make up missed radiation days. Inability to deliver
Up to 5 weeks
Bioavailability of Triapine
The oral bioavailability of the oral form of the triapine will be measured as a numeric value using mass spectrophotometry.

Study Arms (1)
Treatment (triapine, chemoradiation)
EXPERIMENTALPatients undergo pelvic EBRT or IMRT 5 days per week for 5 weeks (25 fractions) with a 3-day boost in week 6, and 1 or 2 applications of LDR brachytherapy in week 6 or 5 fractions of HDR brachytherapy at week 4 or 5. Patients also receive triapine IV over 120 minutes on day 1 and PO on days 2-5, 8-12, 15-19, 22-26, and 29-33 within 90 minutes after pelvic irradiation, and cisplatin IV over 60-120 minutes once weekly for 5 weeks (days 2, 9, 16, 23, and 30). Treatment continues in the absence of disease progression or unacceptable toxicity. Patients may receive a 6th cycle of cisplatin IV during the parametrial boost or any make-up radiation treatment in a sixth week of external beam radiotherapy. Patients undergo the collection of blood samples on study and undergo MRI and FDG-PET/CT during follow-up.

Eligibility Criteria
You may qualify if:
- Patient has a new, untreated histologic diagnosis of stage IB2 (\> 5 cm), II, IIIB, IIIC or IVA squamous, adenocarcinoma, or adenosquamous carcinoma of the uterine cervix or stage II-IVA squamous, adenocarcinoma, or adenosquamous carcinoma of the vagina not amenable to curative surgical resection alone; the presence or absence of lymph node metastasis will be based on pre-therapy 18F-FDG PET/CT; the patient must be able to tolerate imaging requirements of an 18F-FDG PET/CT scan
- Age \>= 18 years old
- Eastern Cooperative Oncology Group (ECOG) performance status score of 0, 1, or 2
- Life expectancy greater than 6 months
- Absolute neutrophil count (ANC) \>= 1.5 x 10\^9/L
- Platelets \>= 100 x 10\^9/L
- Hemoglobin (Hgb) \>= 10.0 g/dL (blood transfusions to reach this amount are allowed)
- Serum creatinine =\< 1.5 mg/dL to receive weekly cisplatin
- If serum creatinine is between 1.5 and 1.9 mg/dL, patients 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)
- Total serum bilirubin =\< 1.5 x upper limit of normal (ULN) (in patients with known Gilbert syndrome, a total bilirubin =\< 3.0 x ULN, with direct bilirubin =\< 1.5 x ULN)
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =\< 2.5 x ULN
- Able to take oral medication
- Not pregnant and not breastfeeding; the effects of triapine on the developing human fetus are unknown; for this reason as well as because heterocyclic carboxaldehydethiosemicarbazones and radiation are known to be teratogenic, women of child-bearing potential and men must agree to use two forms of contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; patient must have documented negative urine pregnancy test must be resulted within 7 days before initiating protocol therapy; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with triapine, breastfeeding should be discontinued if the mother is treated with triapine; these potential risks may also apply to other agents used in this study
- For HIV and hepatitis B/C (HEPB/C):
- HIV-infected patients on effective anti-retroviral therapy with undetectable viral load within 6 months are eligible for the dose escalation portion of this trial; for those patients who are enrolled in the HIV positive (+) expansion cohort, they must be HIV infected and be on retroviral therapy with an undetectable viral load within 6 months of enrollment
- +3 more criteria
You may not qualify if:
- Patient has had a prior invasive malignancy diagnosed within the last three years (except \[1\] non-melanoma skin cancer or \[2\] 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
- Patients receiving any other investigational agents
- Patients with known glucose-6-phosphate dehydrogenase deficiency (G6PD) are excluded due to an inability to administer the antidote for methemoglobinemia, methylene blue; pre-registration testing for G6PD is at the investigator's discretion and is not required for study enrollment
- Patients who are taking any medication associated with methemoglobinemia; medication must be discontinued and must have a washout period of 4 halflives or 4 weeks, whichever is shorter
- History of allergic reactions attributed to compounds of similar chemical or biologic composition to triapine or cisplatin
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection; symptomatic congestive heart failure; unstable angina pectoris; cardiac arrhythmia; known inadequately controlled hypertension; significant pulmonary disease including dyspnea at rest, patients requiring supplemental oxygen, or poor pulmonary reserve; or psychiatric illness/social situations that would limit compliance with study requirements
- Patients with uncontrolled diabetes mellitus (fasting blood glucose controlled by medication, =\< 200 mg/dL allowed)
- 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
- Patients scheduled to be treated with adjuvant consolidation chemotherapy at the conclusion of their standard chemoradiation
