Clinical Trial Summary

To test a new radiation treatment design based on where your cancer is located. Most participants with oropharyngeal cancer are treated with radiation to both sides of the neck. However, for participants with oropharyngeal cancer on one side of the neck, receiving radiation to both sides of the neck may result in increased side effects and radiation exposure. This study is testing the safety and effectiveness of an approach that involves radiation to only one side of the neck in an effort to reduce the overall amount of radiation given and decrease the amount of side effects you may experience.

Description:

Primary Objectives To determine whether: 1. Omission of the contralateral neck cancer treatment is safe and toxicity-sparing for participants with well lateralized oropharyngeal HNSCC undergoing definitive or PORT radiation. This will be demonstrated by acceptably low contralateral neck failures (<15%) Secondary Objectives To determine: 1. the relative difference in symptom burden, as measured by the MDASI_HN area-under-the-toxicity curve (AUC), for initial surgical and initial non-surgical therapy cohorts. 2. Whether omission of the contralateral neck in radiotherapy planning as definitive of PORT treatment for well-lateralized oropharyngeal tumors will impact symptom burden as measured by MDASI AUC, Grade 2 or higher CTCAE v5.0 toxicity, swallow function, and/or feeding tube rates and dependency. 3. Risk adapted therapy approaches lead to differences in distant-metastasis-free survival (DMFS), ipsilateral neck failure, primary site failure, and whether salvage therapy for contralateral neck failures is feasible and effective compared to historical controls.

Eligibility

Inclusion Criteria:

• Newly diagnosed histopathologically-proven p16+ and/or HPV+ HNSCC of the base of tongue or faucial tonsil
• cT1-2N0-1 per AJCC 8th edition staging.
• Tumor does not cross midline, and must be >1cm from midline
• For tonsil tumors, the primary may extend onto the palate or into the BOT but still be >1cm from midline
• No evidence of contralateral neck disease on contrast MRI, CT Head/Neck, PET/CT, or lymphoscintigraphy nor retropharyngeal lymphadenopathy.
• Able to undergo lymphoscintigraphy procedure
• No contraindications for SLNM, adjuvant chemotherapy, RT nor adjuvant/definitive radiotherapy.
• ECOG 0-1
• Age >18 years
• Ability to understand and the willingness to sign a written informed consent document. Exclusion Criteria
• Previous HN Cancer except small skin cancers.
• Any retropharyngeal lymphadenopathy on either MRI, CT, or PET/CT
• Contralateral neck nodal disease radiographically detected per routine diagnostic imaging or SPECT-CT.
• Distant metastatic spread at the time of inclusion
• Chemotherapy or surgery (for the present tumor), prior to inclusion.
• Previous radiation treatment in the head and neck region, for any reason, except for cutaneous lesions that would not lead to overlap with definitive bilateral neck irradiation
• Previous thyroidectomy or neck dissection (causes aberrant nodal drainage)
• Recurrent or second primary tumor in the head and neck region
• Non-tongue base or non-faucial tonsil primaries
• Prior history of regionally advanced or distant spread cancers
• Pregnancy or no active contraception for pre-menopausal women
• Known hypersensitivity to iodine or nanocolloid injection
• Having any condition (physical, mental, sociological) that interferes with the informed consent procedure and follow-up schedules Has a diagnosis of active scleroderma, lupus, or other rheumatologic disease which in the opinion of the treating radiation oncologist precludes safe radiation therapy
