lack of eligible participants due to change in study criterias

The purpose of this research study is to determine the rate of local regional control at 2 years when using de-intensified chemoradiotherapy (CRT) in patients with Human Papillomavirus (HPV)-associated head and neck squamous cell carcinoma (HNSCC). Local regional control means no recurrence of the cancer in the head or neck area. Study subjects will be enrolled into 4 groups. Group/treatment will be based on a number of factors, including smoking and drinking history.

Group/treatment will be based on a number of factors, including smoking and drinking history.

If participants choose to participate, participants will be asked to:

• Participate in screening for eligibility, this will include: questions regarding \medical history, physical exam, blood/urine samples, electrocardiogram, PET/CT and/or CT-MRI of the neck, assessment of tumor, and a questionnaire.
• Complete the study regimen including evaluations and follow up visits. Participants may be in this research study for approximately to 5 years after receiving standard of care (SOC) treatment. Depending on the group enrolled in, the treatment will last either 6 weeks (Groups 1-3) or 15 weeks (Group 4.This group will also receive 3 cycles of SOC induction therapy (One cycle = 21 days). Induction therapy is initial chemotherapy delivered prior to radiation or surgery when treating cancer.
• Participate in routine types of procedures such as clinical exams, blood and urine tests, and imaging tests to assess tumor.
• Consent to storage of research samples.

This research study involves chemotherapy and intensity-modulated radiation therapy (IMRT) IMRT is used to safely deliver precise radiation to a tumor while minimizing the dose to surrounding normal tissue.

There are no added costs associated with participation. There is no reimbursement for participation.

The names of the drugs/interventions involved in this study are:

• Cisplatin
• Docetaxel (Group 4 only)
• Fluorouracil (Group 4 only)
• Carboplatin (Group 4 Only)

All of the drugs listed above are approved for use by the Food and Drug Administration (FDA), commercially available, and considered standard of care (SOC) for cancer.

• Nausea and vomiting
• Diarrhea
• Fever
• Skin irritation, rash
