Head and Neck Treatments

For Head & Neck radiation therapies, a patient’s position needs to be reproduced accurately, in order to ensure effective treatments and minimize side effects. Historically, full-face masks were used to accomplish this. 

But the sub-millimetric accuracy offered by SGRT with AlignRT has enabled clinics to implement open-face masks – or even to move towards completely maskless treatments. 

AlignRT can reduce the complexity of treatment setups and can track motion with better than 1mm accuracy, with reduced need for immobilization. AlignRT is fully integrated into the treatment workflow, allowing for automatic beam pause if the patient moves during treatment delivery.  

The benefits of AlignRT for H&N

43% of patients reporting “significant anxiety” before mask-making sessions²

Studies have shown that patients have reported mask immobilizations, using closed-face masks, to be among the “worst” parts of their Radiation Therapy experiences¹. Nearly half (43%) of patients reported clinically significant anxiety before their mask-making session².  24% of patients were also reported to have some level of session disruption during their first treatment³.  Improving patient comfort while minimizing session disruption are key elements in improving treatment outcomes. 

AlignRT provides patient-centered care for Head and Neck treatments. 

The accuracy of AlignRT enables it to reduce the need for patient immobilizations, resulting in a superior patient experience, while still maintaining and improving the accuracy of setups⁴.  AlignRT, combined with the Postural Video module shows the outline of body parts to help ensure head, shoulders and neck are all positioned correctly, and has been shown in a study to reduce time per fraction by 90 seconds⁵. 

AlignRT also has the potential to better evaluate changes in skin contour due to weight loss earlier than other methods.

The benefits of MapRT for H&N

 

Noncoplanar plans have been shown in multiple studies to deliver increased target dose or reduced organ-at-risk dose (including 19% mean and maximum  dose reduction in one study for nasopharyngeal cancer1). One study shows both increased target coverage and simultaneously reduced dose to some organs at risk.
