Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
In Arm A the researchers will see whether monitoring participants' HPV ctDNA levels can safely identify patients who do not need radiation therapy (RT) after surgery and whose RT can be delayed until their HPV ctDNA levels become detectable.
In Arm B, the researchers will see whether patients who usually need 6-6.5 weeks of CRT can be selected by HPV ctDNA to receive 3 weeks of CRT.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Screening, active surveillance, and treatment (Arm A)
Participants who meet criteria for the treatment phase (a post-operative HPV ctDNA which rose from initial undetectable to meet HPV16 ctDNA criteria and have no clinical or radiographic evidence of gross disease) will undergo delayed standard of care adjuvant radiation (50-60 Gy administered in 1.8-2 Gy fractions) based on the patient's initial pathology. Treatment will be initiated within 4 weeks of a NavDx result. Subjects will undergo FDG PET/CT simulation and standard radiation treatment planning and this FDG PET/CT will also be utilized to rule out distant metastases. Diagnostic FDG PET/CT fusion is also allowed for treatment planning and to rule out distant metastases. Non-therapeutic assessments will be completed.
Intensity-Modulated Radiation Therapy (Arm A)
59.4-60 Gy in 1.8-2 Gy fractions: CTV\_primary, Involved/Adjacent to nodal levels. 50 Gy to this volume is allowed as per MSK institutional standards in patients with clear or close margins and 2-4 involved nodes. 45-50.4 Gy in 1.8-2 Gy fractions: Dissected node positive neck: uninvolved levels that are not adjacent to positive node - Dissected node negative neck
HPV ctDNA Assay
HPV ctDNA evaluation will be completed using NavDx which is a validated digital droplet PCR (ddPCR) assay that targets primers and hydrolysis probes to specifically detect amplicons within the E6 and E7 genes encoded by high-risk HPV strain 16, and the E7 gene for high-risk HPV strains: 18, 31, 33, and 35.
MRI Studies
Research MRI studies will be acquired at Memorial Sloan Kettering using a fast multi-phase spoiled gradient echo sequence. A Gadolinium-based agent will be used for DCE-MRI studies.
EORTC QLQ H&N 35 and C30
The EORTC QLQ H\&N 35 s a validated 35-item site specific assessment tool. The module uses 7 multi-item scales to measure problems with swallowing, senses, speech, social eating and social contact. In addition, 11 single-item scales are utilized in assessing problems with teeth, mouth opening, dry mouth, sticky saliva, coughing, feeling ill, as well as use of analgesics, nutritional supplements, feeding tube and finally, weight gain and weight loss. All of the scales and single item measures range in score from 0 to 100. High scores for the Global Health Status/QoL scale represent high QoL, high scores for the functional scales represent high/healthy levels of functioning, but high scores for the symptom scales/items represent high levels of symptomatology/problems. Scoring the two instruments yields a total of 33 distinct scores and we will examine all of these scored.
MDADI-HN
The MDADI-HN is a questionnaire scored on a scale of 1 to 5, consisting of global, emotional, functional, and physical subscales. The MDADI-HN evaluates the effects of dysphagia on QOL.
COST-FACIT
Comprehensive Score for financial Toxicity or COST survey is a validated screening tool to assess objective and subjective questions about treatment-related financial distress. It is scored from 0-44, where lower composite scores reflect greater risk of financial toxicity.
Screening and deescalated treatment (Arm B)
Participants who meet criteria for the de-escalated treatment phase (Arm B) will undergo adjuvant radiation (30 Gy administered in 2 Gy fractions) with concurrent chemotherapy.
They will undergo FDG PET/CT simulation and standard radiation treatment planning and this FDG PET/CT will also be utilized to rule out distant metastases. Diagnostic FDG PET/CT fusion is also allowed for treatment planning and to rule out distant metastases. Non-therapeutic assessments will be completed and the Study calendar.

Chemoradiation (Arm B)
30 Gy in 2 Gy fractions: CTV\_primary, CTV\_node-positive neck, CTV\_node-negative neck, received de-escalated postoperative chemoradiation. Adjuvant radiation will be administered as previously outlined. Concurrent chemotherapy will be administered as per standard of care. Cisplatin will be administered concurrently with radiation. For non-cisplatin candidates, carboplatin/5fu will be administered. Reasons for using carboplatin/5FU instead of cisplatin need to be charted in the medical record, but the decision belongs to the treating physician. Cisplatin may be given up to 3 days before the scheduled dates, if necessary for medical or personal reasons
