A Prospective Randomized Trial of the Influence of Music on Anxiety in Patients Starting Radiation Therapy for Cancer

Abstract

One of the most downloaded articles in 2017 from the International Journal of Radiation Oncology, Biology, and Physics was a study suggesting that music therapy during radiation therapy (RT) simulation substantially reduces anxiety. To further evaluate the potential of music's clinical efficacy in the context of radiation therapy, we conducted a randomized trial evaluating the influence of genre-based music chosen by the study participant on anxiety during the first RT treatment session with a method that is applicable to routine clinical practice. We conducted a prospective randomized trial of music versus no music during the first RT treatment for cancer. We limited the study to women because prior studies document a higher rate of anxiety in female patients with cancer. Anxiety was evaluated before and after the first RT treatment using the State-Trait Anxiety Inventory (STAI) and Symptom Distress Thermometer (SDT). Patients randomized to music had their preferred genre of music played from a web-based application while in the treatment vault. In the study, 102 females were enrolled (51 with and 51 without music). Baseline high anxiety score before RT was recorded in 48% of patients using the STAI and 58% using the SDT. The percent decrease in mean STAI score was 16% with music versus 10% without music (P = .2197). The mean SDT percent changes were a 13% decrease with music versus a 2% increase without music (P = .3298). This study documents that high anxiety is common in women receiving RT for cancer and that music, as used in this study, does not reduce anxiety to a meaningful degree.
