      PRIMARY OBJECTIVE:&#xD;
&#xD;
      I. To describe the rate of manifestation of an occult primary tumor in the pharyngeal axis or&#xD;
      delayed nodal recurrence in a un-dissected and/or non-irradiated neck at 2 years after study&#xD;
      registration in patients treated with mucosal sparing (and unilateral neck, if applicable)&#xD;
      radiotherapy after resection using transoral surgery for head and neck cancer of unknown&#xD;
      primaries (HNCUP).&#xD;
&#xD;
      SECONDARY OBJECTIVES:&#xD;
&#xD;
      I. To describe the rates and severity of acute and late toxicities and PEG dependence&#xD;
      attributable to mucosal sparing radiotherapy after resection using transoral surgery by&#xD;
      assessment of grade 3 or higher adverse events National Cancer Institute (NCI)-Common&#xD;
      Terminology Criteria for Adverse Events (CTCAE) version (v.) 5.0 criteria.&#xD;
&#xD;
      II. To describe the overall survival, recurrence-free survival (manifestation of an occult&#xD;
      primary in the pharyngeal axis, nodal recurrence in a treated (surgery/radiation therapy&#xD;
      [RT]) neck, delayed lymph node metastasis in an untreated neck (surgery/RT), and distant&#xD;
      failure associated with mucosal sparing radiotherapy.&#xD;
&#xD;
      III. To describe swallowing function changes (assessed via swallowing study) associated with&#xD;
      transoral surgery and adjuvant mucosal sparing radiotherapy.&#xD;
&#xD;

      Patients who have recurrence or progression during treatment or observation have medical&#xD;
      charts reviewed every 6 months for 5 years. Patients who complete adjuvant treatment are&#xD;
      followed for observation 3 days after radiation therapy, 1 month after radiation therapy,&#xD;

    <description>To describe swallowing function changes (assessed via swallowing study) associated with transoral surgery and adjuvant mucosal sparing radiotherapy. Swallowing will be scored (yes, no) for aspiration, penetration, velopharyngeal incompetence, epiglottic eversion, tongue base retraction, and pharyngeal swallow response using the metric outlined by Eisbruch et al. Swallowing assessments will be completed at baseline, along with 3 and 12 months after the completion of protocol XRT. The swallowing questions will be explored descriptively to detect patterns and substantial changes over time. In addition, McNemar's tests (or Wilcoxon signed-rank tests) for paired samples will be used to see if the swallowing questions significantly change over time for each post-baseline time point. MBSImp scoring and the Penetration/aspiration scale scores will be assessed as well.</description>

This early phase I trial evaluates the clinical outcome of mucosal sparing adjuvant
      radiotherapy after surgical exploration in HPV+ head and neck cancer of unknown primaries.
      The purpose of this research is to assess if radiation treatment to the neck only for tumors

      rates of disease control while reducing side effects and toxicity from treatment.
PRIMARY OBJECTIVE:

      I. To describe the rate of manifestation of an occult primary tumor in the pharyngeal axis or
      delayed nodal recurrence in a un-dissected and/or non-irradiated neck at 2 years after study
      registration in patients treated with mucosal sparing (and unilateral neck, if applicable)
      radiotherapy after resection using transoral surgery for head and neck cancer of unknown
      primaries (HNCUP).

      SECONDARY OBJECTIVES:

      I. To describe the rates and severity of acute and late toxicities and PEG dependence
      attributable to mucosal sparing radiotherapy after resection using transoral surgery by
      assessment of grade 3 or higher adverse events National Cancer Institute (NCI)-Common
      Terminology Criteria for Adverse Events (CTCAE) version (v.) 5.0 criteria.

      II. To describe the overall survival, recurrence-free survival (manifestation of an occult
      primary in the pharyngeal axis, nodal recurrence in a treated (surgery/radiation therapy
      [RT]) neck, delayed lymph node metastasis in an untreated neck (surgery/RT), and distant
      failure associated with mucosal sparing radiotherapy.

      III. To describe swallowing function changes (assessed via swallowing study) associated with
      transoral surgery and adjuvant mucosal sparing radiotherapy.

      OUTLINE:

      Patients who have recurrence or progression during treatment or observation have medical
      charts reviewed every 6 months for 5 years. Patients who complete adjuvant treatment are
      followed for observation 3 days after radiation therapy, 1 month after radiation therapy,
      every 3 months after radiation therapy for 2 years, every 6 months for 1 year, and then
      annually for 2 years.

Swallowing will be scored (yes, no) for aspiration, penetration, velopharyngeal incompetence, epiglottic eversion, tongue base retraction, and pharyngeal swallow response using the metric outlined by Eisbruch et al. Swallowing assessments will be completed at baseline, along with 3 and 12 months after the completion of protocol XRT. The swallowing questions will be explored descriptively to detect patterns and substantial changes over time. In addition, McNemar's tests (or Wilcoxon signed-rank tests) for paired samples will be used to see if the swallowing questions significantly change over time for each post-baseline time point. MBSImp scoring and the Penetration/aspiration scale scores will be assessed as well.
measure: Incidence of acute adverse events
time frame: Up to 1 month post-XRT
description: The maximum grade for each type of acute adverse event will be recorded for each patient, and frequency tables will be reviewed to determine patterns, especially focusing on grade 3+ adverse events, regardless of attribution to the study treatment.
measure: Incidence of late adverse events
time frame: Up to 2 years post-XRT
description: The maximum grade for each type of adverse event will be recorded for each patient for up to 2 years post-treatment, and frequency tables will be reviewed to determine patterns, especially focusing on grade 3+ non-hematologic adverse events, regardless of attribution to the study treatment. Hematologic adverse events will not be followed closely long-term given that adjuvant treatment is only given for 1 month.
arm group label: Treatment (follow-up, observation)
arm group type: Experimental
description: Patients who have recurrence or progression during treatment or observation have medical charts are reviewed every 6 months for 5 years. Patients who complete adjuvant treatment are followed for observation 3 days after radiation therapy, 1 month after radiation therapy, every 3 months after radiation therapy for 2 years, every 6 months for 1 year, and then annually for 2 years.
