Clinical Trial Summary

The aim of the study is to evaluate whether open-face masks improve patient comfort/preference whilst maintaining immobilization performance as known for closed masks in patients undergoing whole or partial cranial radiotherapy.

Description:

Upon randomization, patients will be begin treatment either with an open-face mask (A) or closed mask (B). Two individual immobilization masks - the open-face and closed masks - will be fabricated for every single patient. During the 1st half of treatment the randomly assigned mask will be used followed by using another mask for the 2nd half of treatment. Discomfort/pain/anxiety and mask preference will be scored during treatment with a questionnaire.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Patient discomfort with the two immobilization masks	Patient discomfort measured with the Visual Analogue Scale (VAS) 0-10 with "no discomfort" (scored as 0) and "extreme discomfort" (scored as 10).	Change in patient discomfort through the course of radiation therapy, up to 6 weeks
Primary	Mask preference	Mask preference measured with the Yes/No questionnaire. Upon completion of radiation therapy patients will be asked which of the two immobilization masks they prefer - either Yes or No to one of the used masks.	At completion of radiation therapy, up to 6 weeks depending on radiation dose fractionation
Secondary	Treatment set-up accuracy	Measured with planar kilovoltage (kV) imaging	Through the course of radiation therapy, up to 6 weeks
Secondary	Treatment intra-fraction accuracy	Measured with an optic surface imaging (OSI) system	Through the course of radiation therapy, up to 6 weeks
Secondary	Immobilization-mask-induced severe adverse events during treatment	Measured with CTCAE version 5.0	From the baseline to 3 months post-treatment
Secondary	Location of discomfort on the head/face	Measured with the questionnaire consisting of a head/face diagram divided in 8 regions	Changes in location of discomfort on the head/face through the course of radiation therapy up to 6 weeks
