This proposal explores the novel hypothesis that the variability in outcomes within the Intermediate Risk(IR) HPV-positive Oropharynx Squamous Cell Carcinoma(OPSCC) cohort can be exploited to identify a subpopulation that exhibits outcomes similar to Low Risk (LR) HPV-positive Oropharynx Squamous Cell Carcinoma and therefore would be appropriate candidates for radiation dose de-escalation approaches. Current literature using PET, CT, and MRI as single imaging modalities have identified certain criteria within heterogenous patient populations that are associated with clinical outcomes. Here, the investigators will test the hypothesis that multiparametric analysis of simultaneously-acquired MRI and PET quantitative imaging biomarker data from the primary tumor prior to initiating therapy, after 2 weeks of chemoradiation(CRT), and 3 months following completion of chemoradiation in patients with Intermediate Risk HPV-positive Oropharynx Squamous Cell Carcinoma will generate parametric maps that are predictive of clinical outcome.
Furthermore, the investigators will collect blood samples prior to, during, and after radiation therapy to evaluate whether levels of detected circulating tumor cells correlate with response to treatment.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Oropharynx Cancer Patients | Patients with OPSCC will be treated with comprehensive head and neck RT to 70 Gy in 33 fractions with concurrent weekly cisplatin at 40 mg/m2 and at the University of Wisconsin. |

| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| Intensity modulated radiotherapy (IMRT) | Radiation | Intensity modulated radiotherapy (IMRT) will be delivered over 6.5 weeks in 33 daily fractions. Treatments will be initiated on Monday or Tuesday. Missed treatments will be compensated for by delivering an additional BID treatment during the week given at least 6 hours apart OR treating on the Saturday of that week, OR adding to the end of treatment. Gross disease will receive 70 Gy in 2.12 Gy fractions, areas at high-risk for subclinical disease will receive 60 Gy in 1.82 Gy fractions, and areas at low-risk for harboring subclinical disease will receive 56 Gy in 1.70 Gy fractions. |

T-stage, N-stage, and pack-years smoking markers will be used as surrogate markers | Pre-treatment (baseline) and following 2-weeks of CRT (approximately 2-3 weeks on study) |
| Radiographic change in the primary largest pathologic lymph node of patients with LR and IR HPV-positive OPSCC using MRI/PET imaging | Patients with LR and IR HPV-positive OPSCC will be segregated into favorable and unfavourable cohorts using radiographic change(MRI/PET) in the largest pathologic lymph node between pre-treatment and intra-treatment.

| Measure | Description | Time Frame |
|---|---|---|
| Number of Circulating Tumor Cells | Pre-treatment (baseline) and following 2-weeks of CRT (approx. 2-3 weeks on study), 3-months post-treatment (approx. 19-23 weeks on study) | |
| Change in Number of Circulating Tumor Cells Between Time Points | Pre-treatment (baseline) and following 2-weeks of CRT (approx. 2-3 weeks on study), 3-months post-treatment (approx. 19-23 weeks on study) |

| PET-MRI | Diagnostic Test | All imaging data will be acquired using a 3.0T PET-MRI scanner with a standard bore size of 60 cm. Patients will be placed in standard non-ferrous head and neck immobilization devices during PET-MRI to simulate their anticipated positioning during subsequent CT simulation and treatment. A head and neck PET-MRI study will be performed with scan sequences tailored for the site of interest. The PET-MRI exam will take approximately 90 minutes to complete. |
