This phase II trial studies how well stereotactic body radiation therapy with HyperArc software technology works in treating patients with head and neck cancer that has come back. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method can kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue.
PRIMARY OBJECTIVES:
I. To evaluate local control and toxicity of patients who receive escalated dose stereotactic body radiation therapy (SBRT) reirradiation with HyperArc for recurrent head and neck cancer (rHNC).
SECONDARY OBJECTIVES:
I. To evaluate the clinical benefit of HyperArc through the analysis of overall survival (OS), progression-free survival (PFS) and locoregional progression-free survival (LPFS).
EXPLORATORY OBJECTIVES:
I. To evaluate dosimetric data including dose to target and organs at risk (OAR).
OUTLINE:
Patients undergo treatment planning with both standard radiation treatment software and HyperArc software technology. The most optimal plan will be delivered to a total dose of 55 Gy in 5 fractions, given 2-3 times weekly.
After completion of study treatment, patients are followed up periodically for 1 year.

|
| Measure | Description | Time Frame |
|---|---|---|
| Local control rate of the treated tumor target per Response Evaluation Criteria in Solid Tumors version 1.1, magnetic resonance imaging (MRI) response or positron emission tomography (PET) response | Will calculate the percentage and construct 95% exact confidence interval for local control rate. | At 1 year |
| Percent of patients with acute or chronic grade >= 3 treatment-related toxicity per Common Terminology Criteria for Adverse Events version 4.0 | Data will be tabulated and summarized. Incidence of adverse events (AEs) will be summarized overall and with separate summaries for serious adverse events (SAEs), AEs leading to discontinuation, AEs leading to death, etc. The overall safety and tolerability will be assessed throughout the study period. All AE data will be listed individually by patient identifier. | At 1 year |
| Measure | Description | Time Frame |
|---|---|---|
| Overall survival (OS) | The Kaplan-Meier method will be used to provide an estimate of OS. The corresponding 95% confidence interval will also be presented. | The time between the first dose of stereotactic body radiation therapy (SBRT) and death, assessed at 1 year |
| OS |
| Measure | Description | Time Frame |
|---|---|---|
| Dosimetric data including achievable dose to target and organs at risk (OAR) | Data will be collected but not analyzed. | Up to 2 years |
| Serum markers predictive of response and/or toxicity | Will perform correlation analysis to explore serum markers predictive of efficacy endpoints. |
