Study Summary
The investigators propose evaluating the feasibility of using the novel cone beam computed tomography (CBCT)-guided Ethos system to deliver expedited, adaptive Quad shot radiation for the purpose of palliative radiation of patients with advanced head and neck cancers or patients with a history of any malignancy experiencing current head and neck lesions. Quad shot radiation was selected as the palliative regimen of choice given its low toxicity profile, well published efficacy in palliation, frequent usage in the US for palliation of head and neck cancers, and safety in the setting of re-irradiation. The use of the Ethos platform to perform online adaptive radiation planning and delivery remains novel and untested. The Ethos system would be used to consolidate CT simulation, replanning, and treatment for Quad shot patients receiving treatment with the benefit of reduced patient travel and a reduction in the unwanted delay between Quad shot cycles. The goal of this pilot study will be to evaluate the feasibility of the Ethos system to eliminate the need for a CT simulation for cycles 2 and 3 of Quad shot radiation.
Interventions
- DEVICE Ring gantry kV-CBCT combined with linear accelerator (Halcyon)
