This phase II trial studies how well standard chemotherapy and radiation therapy given with or without paclitaxel and carboplatin work in treating human immunodeficiency virus (HIV)-positive women with cervical cancer that has spread to nearby tissue or lymph nodes. Drugs used in chemotherapy, such as cisplatin, paclitaxel, and carboplatin work in different ways to stop the growth of tumor cells. They may either kill the cancer cells by stopping them from dividing, or by stopping them from spreading. Radiation therapy to the pelvis destroys potential cancer cells in the pelvic area and significantly reduces the risk of tumor recurrence in the pelvic area. It is not yet known if giving chemotherapy and radiation therapy with paclitaxel and carboplatin afterward may work better than than just chemotherapy and radiation therapy in treating HIV-positive patients with advanced cervical cancer.

STANDARD CARE: All participants receive cisplatin intravenously (IV) over 30-60 minutes on days 1, 8, 15, 22, 29, and 36. Patients also undergo radiation therapy over 2-5 fractions for 5 days a week, for up to 8 weeks in the absence of disease progression or unacceptable toxicity. Four (4) to 8 weeks after finishing standard chemotherapy and radiation, participants are randomized to 1 of 2 arms.

RANDOMIZED ARMS:

Arm I: Patients receive carboplatin IV over 1 hour and paclitaxel IV over 3 hours on day 1. Courses repeat every 21 days for up to 4 courses in the absence of disease progression or unacceptable toxicity. Participants are followed at 3, 6, 9, 12, 18 and 24 months for recurrence or progression.

Arm II: Participants undergo active monitoring at 3, 6, 9, 12, 18 and 24 months for recurrence or progression.

This trial will be conducted at selected AIDS Malignancy Consortium sites in Sub-Saharan Africa.

Eligibility Criteria for Screening

• Ability to understand and the willingness to provide informed consent.
• Participant has clinically diagnosed LACC and self-reports as HIV-positive
• Age ≥ 18 years. DOB and age will be determined based on best possible information or documentation available.
• ECOG performance status ≤ 2 (Karnofsky ≥ 50%, see Appendix III).

Inclusion Criteria for chemoradiation treatment enrollment:

• Participants with locally advanced primary, untreated, histologically-confirmed, documented invasive squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma of the uterine cervix, adequately clinically staged by standard clinical guidelines, with Federation of Gynecology and Obstetrics (FIGO) stages IIB, III, or IVA

• HIV positive. Documentation of HIV-1 infection by means of any one of the following:

  • Documentation of receipt of ART by a licensed health care provider (documentation may be a record of an ART prescription in the participant's medical record, a written prescription in the name of the participant for ART, or pill bottles for ART with a label showing the participant's name)

  • HIV-1 ribonucleic acid (RNA) detection by a licensed HIV-1 RNA assay demonstrating >1000 RNA copies/mL confirmed by a licensed screening antibody and/or HIV antibody antigen combination assay

  • Any licensed HIV screening antibody and/or HIV antibody/antigen combination assay confirmed by a second licensed HIV assay such as a HIV-1 Western blot confirmation or HIV rapid multispot antibody differentiation assay.

    • Note: The term "licensed" refers to a kit that has been certified or licensed by an oversight body within the participating country and validated internally. WHO (World Health Organization) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.

• Hemoglobin >= 10 g/dL (6.2 mmol/L) (participants receiving transfusion are permitted) (within 4 weeks prior to enrollment)

• Leukocytes: >= 3,000/mm^3 (3.0 x 10^9/L) (within 4 weeks prior to enrollment)

• Absolute neutrophil count: >= 1,500/mm^3 (1.5 x 10^9/L) (within 4 weeks prior to enrollment)

• Platelets: >= 100,000/mm^3 (100 x 10^9/L) (within 4 weeks prior to enrollment)

• CD4 T-cell count a minimum of 200 cells/uL (within 4 weeks prior to enrollment)

• Total bilirubin =< 2 x institutional upper limit of normal (ULN) unless related to antiretroviral use (e.g., atazanavir or indinavir), then the direct bilirubin must be =< 2 x ULN (within 4 weeks prior to enrollment)

• Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]): =< 3 x ULN (within 4 weeks prior to enrollment)

• Creatinine levels within normal institutional limits or, creatinine clearance >= 60 mL/min/1.73 m^2 (1.00 mL/s) calculated by the Cockcroft-Gault equation for women for participants with creatinine levels above institutional normal (within 4 weeks prior to enrollment)

• All participants must be prescribed combination antiretroviral therapy with the goal of virological suppression using an acceptable regimen that adheres to national guidelines for treatment of HIV infection. If on a ritonavir- or cobicistat-based regimen, the participant must be switched to a non-ritonavir/ cobicistat-based regimen at least 7 days before treatment enrollment. Participants not on ART must start an acceptable regimen at least 7 days before treatment enrollment.

• In the investigator's opinion the participant is suitable for treatment with radical intent using concurrent chemotherapy and pelvic radiation followed by adjuvant chemotherapy

• Participants of childbearing potential, defined as a sexually mature woman who: 1) has not undergone a hysterectomy or bilateral oophorectomy; or 2) has not been naturally postmenopausal for at least 24 consecutive months (i.e., has had menses at any time in the preceding 24 consecutive months), must have a negative urine or serum pregnancy test within 3 weeks prior to enrollment and agree to use an effective form of contraception (e.g., barrier contraception, highly effective hormonal contraception) for the duration of treatment and for 6 weeks after stopping treatment
