Background: Massage as a manual therapy has shown benefit for symptomatic relief in patients with cancer and their caregivers. We explored the impact of a single massage session on self-reported symptoms in an outpatient clinic at a comprehensive cancer center. Methods: Patients and caregivers received oncology massage treatments (30 or 60-min duration) at our Integrative Medicine Center outpatient clinic from Sep 2012-Jan 2015. Participants completed a modified Edmonton Symptom Assessment Scale (ESAS; 0-10 scale, 10 most severe) pre- and post-massage. ESAS individual items and subscales scores of Physical Distress (PHS), Psychological Distress (PSS), and Global Distress (GSD) were analyzed. We used paired t-tests with a Bonferroni correction (i.e., p < .001) to examine pre/post massage self-reported symptoms. Results: Initial massage visits for 164 patients and 39 caregivers were analyzed. Highest symptoms burden (means) at baseline for patients were Sleep 3.93, Fatigue 3.70, and poor sense of Well-Being 3.62; for caregivers Distress 4.14, Sadness 3.43, and Sleep 3.21. Although patients reported significantly more physical symptoms (F = 27.56, P < .0001) compared to caregivers at baseline, groups did not differ in regard to psychological symptom burden (P = .75). Massage therapy was associated with significant improvements in PHS, PSS, and GSD for both patients and caregivers at P < .0001. Including participants with symptom report ≥ 1, massage resulted in a clinically significant improvement (reduction ≥ 1) in pain, fatigue, sleep, distress, dry mouth, sadness, numbness, anxiety, wellbeing for patients; pain, fatigue, distress, sadness, numbness, anxiety, wellbeing for caregivers. Regarding massage duration, there were no significant effects for 30 vs 60-min duration on pre/post ESAS difference scores. Conclusions: A single 30- or 60-minute massage session resulted in acute relief of self-reported symptoms in patients and caregivers. Further study is warranted regarding optimal massage dose and frequency.
