This is a single-arm, phase II study that is designed to investigate nodal and primary tumor CTV dose de-escalation (30 Gy) in HPV positive oropharyngeal cancer.
The purpose of this research is to determine if a decrease in the dose of radiation to regions which have no visible cancer will be as effective as the standard dose. The dose to all visible cancer remains unchanged to the standard radiation approach. The researchers believe that a lower dose could be just as helpful for treatment, while reducing the side effects of radiation and improving quality of life. The current standard care treatment for OPSCC can have debilitating side effects. Using a decreased dose of 30 Gy from 46-54 Gy to regions without visible cancer but which have a risk of microscopic cancer might be just as effective for treating cancer with less side effects. The combination of these approaches is not considered the current standard of care. Patients will continue to receive standard systemic therapy of cisplatin during radiation therapy.

Subjects will continue to receive standard systemic therapy of cisplatin during radiation therapy. Weekly SOC Cisplatin at a dose of 40mg/m2 or every 3-week dosing of 100mg/m2 will be administered per institutional guidelines during radiation therapy. The first cisplatin infusion should be initiated during the window from 24 hours before, to 48 hours after the first scheduled radiation treatment. Skipped cisplatin infusions should not be made up, and the last cisplatin infusion should be no later than 7 days after the last fraction of radiation.
Radiotherapy will involve a sequential boost approach. Treatment will begin with coverage of the primary site and elective nodal regions to 30 Gy, after which treatment volumes will be reduced to primary site and involved nodes only with PTV margin to 70 Gy.

RECRUITINGChange in dose and volume to all clinical target volumes (CTV) via Progression-Free Survival (PFS)
To evaluate the efficacy of a reduction in dose and volume to all clinical target volumes (CTV) in patients with HPV-positive squamous cell carcinoma of the oropharynx (OPSCC) using 2-year Progression-Free Survival (PFS). Efficacy will be determined by the PFS rate at 2 years post-treatment, through continuous assessment with a boundary of 10% progression at 2 years (90% 2 year PFS).
Time frame: 2 years post treatment
Safety evaluated per CTCAE v6
To evaluate safety by collecting adverse events per CTCAE v6 in patients who have HPV positive SCC of the oropharynx using a reduction in primary tumor and nodal CTV dose to 30 Gy.
Time frame: Adverse events collected through 30 days post treatment and SAEs through 90 days post-treatment or until commencement of new anti-cancer therapy, whichever occurs first.
Quality of life measured by MDADI
The MDADI is a patient-reported outcome (PRO) instrument designed to assess swallowing-related quality of life in patients with head and neck cancer and dysphagia. It evaluates the functional, emotional, and physical impact of swallowing difficulties on daily life. The scale ranges from 20 - 100. Higher scores indicate better swallowing function and better swallowing-related quality of life. Lower scores indicate worse dysphagia-related quality of life To assess the impacts on quality of life on patients who have HPV positive SCC of the oropharynx who receive a reduction in CTV dose to 30 Gy as well as a reduction in CTV volumes, via the EORTC QLQ-C30 at baseline, week 7/EOT, 6 months, 12 months 18 months and 24 months following completion of radiation therapy.
Time frame: Baseline, at time of treatment completion, at 6-month intervals following treatment until 2 years after completion of RT
Quality of life measured by EORTC QLQ-C30
European Organisation for Research and Treatment of Cancer - Quality of Life Questionnaire-Core 30. t is a validated patient-reported outcome (PRO) instrument designed to assess health-related quality of life (HRQoL) in patients with cancer across clinical trials and routine practice. The transformed scale ranges from 0 - 100. Functional and Global Health scales: higher = better Symptom scales/items: higher = worse To assess the impacts on quality of life on patients who have HPV positive SCC of the oropharynx who receive a reduction in CTV dose to 30 Gy as well as a reduction in CTV volumes, via the EORTC QLQ-C30 at baseline, week 7/EOT, 6 months, 12 months 18 months and 24 months following completion of radiation therapy.
