Brief Summary

This trial studies how well digital PET scan works in predicting outcomes in patients with oropharyngeal cancer that has spread from where it started to nearby tissue or lymph nodes (locally advanced). The development of digital detectors for PET is a technological improvement in medical imaging that could potentially impact many areas of clinical oncology, including staging, radiation planning accuracy, and the assessment of treatment response. Digital technology may improve PET imaging performance by providing better timing, energy and spatial resolution, higher count rate capabilities and linearity, increased contrast, and reduced noise. Utilizing digital PET scan, may work better in predicting outcomes and treatment response in patients with oropharyngeal cancer compared to conventional PET.

Detailed Description

PRIMARY OBJECTIVE:

I. To evaluate the utility of early (i.e. during treatment) digital positron emission tomography (dPET) as a diagnostic tool to predict local control 6 months after definitive chemoradiation for patients with locally advanced oropharyngeal carcinoma.

SECONDARY OBJECTIVES:

I. To study the association between dynamic dPET parameters taken at early time points (i.e. during treatment) and CR on PET after definitive chemoradiation.

II. To study the association between dynamic dPET parameters taken at early time points (i.e. during) treatment and 2 year local control after definitive chemoradiation.

III. To assess the ability of dynamic dPET compared to conventional PET or conventional-equivalent dPET reconstruction to identify tumor volumes with greater sensitivity at the time of before (dPET1), during (dPET2, dPET3) and after (dPET4, dPET5) chemoradiation.

IV. To generate preliminary data for future methodology or clinical trials.

OUTLINE:

Patients receive fludeoxyglucose F-18 via injection and undergo dPET over 20 minutes after standard of care computed tomography (CT) imaging (week -2), after receiving 20-26 Gy and 40-46 Gy of radiation (weeks 3 and 5), and 3 months after completion of treatment. Patients with concern for residual disease may receive an additional dPET 6 months after treatment.

Conditions

Clinical Stage II HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8; Clinical Stage III HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8; Locally Advanced Oropharyngeal Squamous Cell Carcinoma; Pathologic Stage II HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8; Pathologic Stage III HPV-Mediated (p16-Positive) Oropharyngeal Carcinoma AJCC v8; Stage III Oropharyngeal (p16-Negative) Carcinoma AJCC v8; Stage IVA Oropharyngeal (p16-Negative) Carcinoma AJCC v8; Stage IVB Oropharyngeal (p16-Negative) Carcinoma AJCC v8

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP

Eligibility Criteria

Inclusion Criteria

• Patient who will undergo definitive radiation with concurrent chemotherapy with cisplatin 40 mg/m^2 weekly (preferred) or high dose cisplatin 100 mg/m^2 for histologically confirmed locally advanced squamous cell carcinoma of the oropharynx
• Patient must have clinically or radiographically evident measurable disease at the primary site and at nodal station(s). Tonsillectomy or local excision of the primary or nodal disease is not permitted
• p16 and/or human papillomavirus (HPV) status obtained on biopsy specimen (archival or fresh)
• Patients must provide their personal smoking history prior to registration
• Patients must fall into one of the following stage (American Joint Committee on Cancer [AJCC] 8) and risk groups based on pre-treatment work-up and smoking history:

• Low risk classification:

• p16 and/or HPV positive, T1-3, N1-2, M0 with =< 10 pack years smoking history OR
• Intermediate risk classification:

• p16 and/or HPV positive, T4, N3, M0 and/or HPV positive with > 10 pack year smoking history
• HPV negative, T1-3, N1-2b, M0, with =< 10 pack years smoking history OR

• Clinical or radiologic evidence of metastatic disease as defined by disease below the clavicles
• Simultaneous primary cancers or separate bilateral primary tumor sites with the exception of patients with bilateral tonsil cancers
• Subjects who are breast-feeding, or have a positive pregnancy test will be excluded from the study. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Medical contraindications to PET imaging (e.g. pregnancy, nursing mothers, weight greater than 420 pounds)
• Medical contraindications to cisplatin or prior allergic reaction to cisplatin
