Short communicationA brief yoga intervention implemented during chemotherapy: A randomized controlled pilot study

- This pilot study supported feasibility of investigating a brief yoga intervention.
- The novel yoga intervention is implemented in the clinic during chemotherapy.
- Lessons learned will strengthen studies to further evaluate the intervention.

ObjectivesFatigue and other treatment-related symptoms (e.g., sleep disturbance) are critical targets for improving quality of life in patients undergoing chemotherapy. Yoga may reduce the burden of such symptoms. This study investigated the feasibility of conducting a randomized controlled study of a brief yoga intervention during chemotherapy for colorectal cancer.DesignWe randomized adults with colorectal cancer to a brief Yoga Skills Training (YST) or an attention control (AC; empathic attention and recorded education).SettingThe interventions and assessments were implemented individually in the clinic while patients were in the chair receiving chemotherapy.InterventionsBoth interventions consisted of three sessions and recommended home practice.Main outcome measuresThe primary outcome was feasibility (accrual, retention, adherence, data collection). Self-reported outcomes (i.e., fatigue, sleep disturbance, quality of life) and inflammatory biomarkers were also described to inform future studies.ResultsOf 52 patients initially identified, 28 were approached, and 15 enrolled (age Mean = 57.5 years; 80% White; 60% Male). Reasons for declining participation were: not interested (n = 6), did not perceive a need (n = 2), and other (n = 5). Two participants were lost to follow-up in each group due to treatment changes. Thus, 75% of participants were retained in the YST and 71% in the AC arm. Participants retained in the study adhered to 97% of the in-person intervention sessions and completed all questionnaires.ConclusionsThis study demonstrated the feasibility of conducting a larger randomized controlled trial to assess YST among patients receiving chemotherapy for colorectal cancer. Data collected and challenges encountered will inform future research.
