Phase II Trial Evaluating Selective Minimal Residual Disease Directed Adjuvant Radiation in Human Papilloma Virus Associated Oropharynx Carcinoma

Summary

This study will look at whether monitoring HPV ctDNA levels is an effective way to detect cancer relapse risk in people with HPV-OPC. All participants will have recently had surgery to treat their disease, or they will be scheduled to have this surgery. 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.

Interventions

• Diagnostic Test
  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.

• Diagnostic Test
  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.

• Behavioral
  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.
