Description: For this phase 2, randomized trial (ClinicalTrials.gov Identifier: NCT03164460), researchers are evaluating whether stereotactic body radioablative therapy (SBRT) is superior to conventional radiation among patients with head and neck cancer.

All patients will have small, inoperable tumors that have been previously irradiated.

This study has 2 arms: the SBRT arm, in which patients will receive 45 Gy in 5 fractions over about 2 weeks, and the conventional radiation arm, in which patients will receive 66 to 70 Gy in 33 to 35 fractions over 6 to 7 weeks.

All patients will complete questionnaires at baseline, during treatment, and after treatment.

The primary outcome measure is toxicity. Secondary measures include local disease control, locoregional failure-free survival, and patient-reported outcomes.

Status: This study is open and recruiting patients as of June 15, 2017.

This study is sponsored by the MD Anderson Cancer Center.
