Brief Summary
Previous studies of this type of head and necl cancer have shown high rates of cancer control but result in many short and long term side effects when treated with high dose radiation and chemotherapy. Recently, investigators have noticed similar high rates of cancer control in small numbers of patients who receive less intensive treatments using lower doses of radiation, smaller radiation fields with chemotherapy. It is expected that the side effects of treatment with lower doses of radiation would be less. For this reason this study is looking at a different regimen of reducing the intensity of the treatment. The purpose of this study is to compare any good and bad effects of using lower dose smaller fields radiation therapy and chemotherapy with published outcomes. This study will allow the researchers to know whether these different approaches are better, the same, or worse than the usual approach. To be better, the study approach should result in the same survival rate of the usual approach (about 85 out of 100 patients alive and free of cancer at 2 years) but with less long-term side effects.

Outcome Measures
Primary Outcomes (1)
Two-year progression free survival
Assuming the primary endpoint (non-inferior 2 year locoregional control) is met and both of these toxicity outcome goals are met, then concurrent short course radiotherapy would be considered an effective and less toxic alternative to concurrent standard arm, in locally advanced HPV-associated carcinoma of the oropharynx.

Study Arms (1)
Experimental
EXPERIMENTALCisplatin: 30-40 mg/m2/week, every week during radiation. Dose should be based on actual body weight. The first cisplatin infusion should be started within 24 hours before or after the first scheduled radiation treatment. Intensity Modulated Radiation Therapy (IMRT) and Image-Guided Radiation Therapy (IGRT) are mandatory for this study. 55 Gy radiation in 5 weeks using 5 fractions per week + Cisplatin every week
Interventions
Instead of standard bilateral or extensive neck fields, the current radiation fields will cover disease with only 3cm expansion. The clinical target volumes doses are biologically equivalent to the standard but given in a shorter hypofractionated approach.
Eligibility Criteria
You may qualify if:
- Pathologically proven diagnosis of squamous cell carcinoma of the oropharynx (tonsil, base of tongue, soft palate, or oropharyngeal walls)
- Patients must have clinically or radiographically evident measurable disease at the primary site or at nodal stations.
- P16-positive based on local site immunohistochemical tissue staining
- Clinical stage T1-3, N1-2, M0 (AJCC, 8th ed.)
- Age ≥ 65.
- Normal organ and marrow function within 14 days prior to registration defined as follows:
- Absolute neutrophil count ≥ 1,500/mcL
- Platelets ≥ 100,000/mcL
- Hemoglobin ≥ 8.0 g/dL
- Total bilirubin ≤ 1.5× institutional upper limit of normal (ULN)
- AST(SGOT) or ALT(SGPT) ≤ 3.0 × institutional ULN
- Serum creatinine ≤ 1.5× ULN
You may not qualify if:
- Metastatic disease
- Recurrent disease after primary management Cancers with center of mass is outside the oropharyngeal boundaries
- Synchronous double primaries
- Prior radiotherapy for lymphoma or other malignancy
- Prior systemic therapy including immunotherapy
- Severe active comorbidity where life expectancy is \<1 year.
- Autoimmune disease
