Guest Editor’s Note: Despite the high prevalence of cancer-related fatigue, there are few effective management strategies for this debilitating condition. Music therapy is a nonpharmacologic modality that has been shown to reduce anxiety in oncology settings. In this installment of The ASCO Post’s Integrative Oncology series, Kevin Liou, MD, and Karen Popkin, LCAT, MT-BC, HPMT, describe the study conducted by their group to determine the potential of music therapy in alleviating cancer-related fatigue.

Cancer-related fatigue in hospitalized patients is a debilitating and disruptive symptom that contributes to increased use of health-care resources. Music therapy is an evidence-based intervention that uses various approaches, ranging from receptive or passive techniques (music listening) to more active techniques (singing, selecting songs). Preliminary findings suggest a potential benefit of music therapy in managing cancer-related fatigue in inpatient settings. However, data are lacking on which music therapy techniques are most effective.
Understanding Cancer-Related Fatigue
Cancer-related fatigue occurs in up to 90% of patients treated for cancer and is of particular concern for hospitalized patients, with the majority reporting moderate-to-severe fatigue.1-4 It is defined by the National Comprehensive Cancer Network (NCCN) as a “distressing, persistent, subjective sense of tiredness or exhaustion related to cancer or cancer treatment which is not proportional to recent activity and interferes with usual functioning.”2
Cancer-related fatigue is associated with longer hospitalizations and higher risk of readmission.3 In addition, it interferes with patients’ ability to complete their cancer treatments and to engage in routine daily activities, which can diminish health-related quality of life and ultimately affect overall survival.5,6 Despite the high prevalence of cancer-related fatigue and its deleterious impact, 60% of patients in a large survey reported cancer-related fatigue as inadequately addressed.1
Role of Music Therapy
Music therapy is a complementary modality offered at nearly 50% of National Cancer Institute–designated comprehensive cancer centers.7 Board-certified music therapists engage patients in music-based activities within a therapeutic relationship.8 They seek to empower and engage patients through active or passive music therapy. With active music therapy, patients sing, play instruments, write lyrics, or select music and then listen, move, and/or discuss their musical experience. With the more receptive, passive music therapy, therapists provide music to guide patients into a calm, restful, or meditative state.
The Society for Integrative Oncology recommends music therapy for alleviating anxiety and depression, but its benefits for cancer-related fatigue are inconclusive.9 A Cochrane review (6 trials, n = 253) reported a small-to-moderate effect of music therapy on cancer-related fatigue, but the quality of evidence was deemed as low.10 Our group sought to address the knowledge gap by conducting a cross-sectional mixed-methods study.

The study took place at Memorial Sloan Kettering Cancer Center in New York; we enrolled 436 hospitalized adults with cancer, including hematologic, breast, gastrointestinal, and gynecologic. We offered active music therapy to 360 patients and passive music therapy to 76 based on the music therapist’s assessment, patient preference, and baseline patient-reported symptoms. We tailored the length of sessions (20–30 minutes) to suit patient stamina and engagement. To assess cancer-related fatigue, we used the Edmonton Symptom Assessment Scale fatigue item11 before and after music therapy sessions. Patients were also asked to provide free-text comments following their sessions.
Among patients with moderate or severe fatigue, active music therapy was associated with a 0.88-point greater reduction in cancer-related fatigue (95% confidence interval = 0.26–1.51; P = .006; Cohen’s D = 0.52) compared with passive music therapy. Analysis of free-text responses revealed higher frequencies of words describing positive emotions among participants in active music therapy.12
In a large sample of inpatient adults with diverse cancer types, active music therapy was associated with a clinically and statistically significant improvement in cancer-related fatigue. It was also correlated with increased reporting of positive emotions compared with receptive or passive music therapy techniques. Rigorous randomized trials are necessary to confirm these findings. More studies are also needed to determine the mechanisms underlying the effects of different music therapy techniques. This research will help inform more targeted approaches to address this challenging symptom and ultimately improve clinical outcomes for patients with cancer-related fatigue.
