Brief summary: This phase II trial studies nab-paclitaxel (paclitaxel albumin-stabilized nanoparticle formulation) and carboplatin followed by response-based local therapy in treating patients with stage III or IV human papillomavirus (HPV)-related oropharyngeal cancer. Drugs used in chemotherapy, such as paclitaxel albumin-stabilized nanoparticle formulation, carboplatin, hydroxyurea, fluorouracil, paclitaxel, and 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 spreading. Radiation therapy uses high energy x rays to kill tumor cells. Giving nab-paclitaxel and carboplatin before chemoradiation may make the tumor smaller and reduce the amount of chemotherapy and radiation therapy needed. Assigning chemotherapy and radiation therapy based on response (response-based therapy) and giving patients who are responding well lower doses of treatment may help reduce the occurrence of side effects.

Detailed description: PRIMARY OBJECTIVES:

I. To determine the 2-year progression-free survival (PFS).

SECONDARY OBJECTIVES:

I. Clinical complete response rate (nab-paclitaxel based induction, compared to European Prospective Investigation into Cancer and Nutrition \[EPIC\] induction \[paclitaxel based\]).

II. Response rate (nab-paclitaxel based induction, compared to EPIC induction \[paclitaxel based\]).

III. Proportion of patients with \>= 50% shrinkage by Response Evaluation Criteria In Solid Tumors (RECIST) (nab-paclitaxel based induction, compared to EPIC induction, paclitaxel based).

IV. Toxicity (nab-paclitaxel based induction, compared to EPIC induction \[paclitaxel based\]).

V. To assess swallowing function and speech at 6 months (mos) and 12 mos post therapy.

VI. To determine the rates of late toxicity with chemoradiation following surgery as determined by xerostomia, dental decay, osteroradionecrosis, G-tube dependency, tracheostomy placement and dysphagia.

VII. 2-year overall survival (OS) in patients treated on the Low-Risk, Intermediate-Risk Arm, and High-Risk Arms.

VIII. 2-year PFS in patients treated on the Low-Risk, Intermediate-Risk Arm, and High-Risk Arms - early and late toxicities.

IX. Evaluate need for post radiotherapy/chemoradiotherapy (RT/CRT) surgery on low- and intermediate-risk arms based on response from induction chemotherapy.

X. Evaluate in a descriptive manner the role of transoral robotic surgery (TORS) resection/lymph node dissection (LND) when integrated into a de-escalation trial.

TERTIARY OBJECTIVES:

I. To evaluate pathologic/histologic appearance of tumor after induction chemotherapy and after CRT.

II. Translational research on blood and tissue samples. III. To profile tumors genetically and immunologically in order to assess in a descriptive manner genetic or immunological features characteristic of clinical behavior.

OUTLINE:

INDUCTION CHEMOTHERAPY: All patients receive paclitaxel albumin-stabilized nanoparticle formulation intravenously (IV) over 60 minutes on days 1, 8, and 15 and carboplatin IV over 30-60 minutes on day 1. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity.

Patients are then assigned to 1 of 3 treatment groups based on response to induction chemotherapy.

GROUP A (LOW-DOSE ARM): Patients undergo radiation therapy once daily for 5 weeks.

GROUP B (INTERMEDIATE-DOSE ARM): Patients receive hydroxyurea orally (PO) twice daily (BID) on days 0-5, fluorouracil IV continuously on days 1-5, and paclitaxel IV over 60 minutes on day 1. Patients also receive low-dose radiation therapy BID on days 1-5. Treatment repeats every 14 days for 3 courses in the absence of disease progression or unacceptable toxicity.

GROUP C (STANDARD-DOSE ARM): Patients receive hydroxyurea PO BID on days 0-5, fluorouracil IV continuously on days 1-5, and paclitaxel IV over 60 minutes on day 1. Patients also receive standard-dose radiation therapy BID on days 1-5. Treatment repeats every 14 days for up to 5 courses in the absence of disease progression or unacceptable toxicity.\*

\*NOTE: At the discretion of the principal investigator (PI), patients may receive cisplatin IV over 1-3 hours every 3 weeks during radiation therapy instead of paclitaxel and undergo daily radiation therapy.

After completion of study treatment, patients are followed up for 30 days, every 3 months for 1 year, every 6 months for 2 years, and then annually for 2 years.

Eligibility criteria: Inclusion Criteria:

* Patients must have pathologically confirmed HPV-positive squamous cell carcinoma
* HPV testing must follow the following criteria

  * HPV testing using an E6/E7 based assay is preferred, and does not require any validation (e.g. HPV in situ hybridization \[ISH\] or HPV E6/E7 polymerase chain reaction \[PCR\])
  * For oropharyngeal tumors p16 immunohistochemistry (IHC) positivity is sufficient to enroll and initiate treatment (p16 IHC interpretation to follow guidelines by Jordan/Lingen et al 2012); it is recommended that p16 IHC positivity is validated at a later point (during or after treatment) using an E6/E7 based test at the University of Chicago and provided slides will be used
  * For non-operative (OP) tumors accurate HPV testing (i.e. ISH, or E6/E7 based testing) is required for enrollment and treatment initiation
* Availability of \>= 10 unstained 5 micron slides
* Patients with American Joint Committee on Cancer (AJCC) (7th edition, 2010) nodal stage N2 or N3 or a T4 primary tumor
* The primary and nodal involvement must be assessable on clinical exam (mucosal and lymph node exam)
* The primary and nodal involvement must have been defined bi- or uni-dimensional measurements measurable by RECIST
* No previous radiation or chemotherapy for a head and neck cancer
* No surgical resection for a head and neck cancer within 8 weeks of enrollment (although lymph node biopsy including excision of an individual node with presence of residual nodal disease, or surgical biopsy of the tumor is acceptable)

* Alkaline phosphatase =\< 2.5 X ULN
* Patients must sign a study-specific informed consent form prior to study entry; patients should have the ability to understand and the willingness to sign a written informed consent document

Exclusion Criteria:
