Yoga for chronic chemotherapy-induced peripheral neuropathy pain: a pilot, randomized controlled trial

Abstract

Purpose: To determine the feasibility of implementing a yoga intervention for cancer survivors with chronic CIPN pain, as well as the impact of the intervention on patient-reported outcomes. Methods: Cancer survivors with chronic CIPN pain were recruited from the breast, gastrointestinal, and gynecological oncology centers at Dana-Farber Cancer Institute. Participants were randomized (2:1) to receive an 8-week yoga intervention or usual care. After 21/50 of participants were enrolled, the COVID-19 pandemic required the yoga intervention to be delivered virtually (i.e., Zoom). Pre- and post-intervention, participants self-reported CIPN and co-occurring symptom severity. Adherence to the intervention was defined as practicing ≥ 12 yoga sessions over the 8-week intervention period. Changes in patient-reported outcomes between groups were compared using Wilcoxon’s rank-sum tests. Results: Participants (n = 28 yoga, n = 16 control) were mainly female (96%) and diagnosed with stage III/IV disease (66%). Overall, 19/28 (67.8%) of yoga group participants were adherent to the yoga protocol. Yoga group participants experienced significant within-group improvements in all patient-reported outcomes, including worst CIPN pain (median change = − 1.7, p < 0.0001) and sensory CIPN (median change = − 14.8, p < 0.0001), but only improvements in fatigue (p = 0.05) and depression (p = 0.04) were significant compared to the control. There were no differences (p > 0.05) in changes in patient-reported outcomes between in-person (n = 6) or virtual (n = 15) yoga group participants. Conclusions: Yoga is a feasible non-pharmacological modality for cancer survivors with CIPN, but more information is needed regarding its impact on CIPN and other symptoms. Trial registration: ClinicalTrials.gov Identifier: NCT03824860 Implications for Cancer Survivors: Oncology clinicians may consider referring cancer survivors to yoga for chronic CIPN pain, but yoga cannot be currently recommended as an efficacious treatment.
