Predictors of Anxiolytic Requirement During Radiation Therapy With Thermoplastic Mask Immobilization

History of anxiety and claustrophobia were independently predictive of AR during radiation simulation/treatments with a thermoplastic mask. These factors can be detected in patient charts prior to consultation and therefore have the potential to allow for early identification of individuals who may be at higher risk for anxiety during their radiation experience. Furthermore, patients who required anxiolytics during radiation therapy tended to miss more treatment days, possibly indicating that optimal anxiety management has not yet been achieved.
