The effects of mindfulness meditation and progressive muscle relaxation on fatigue and quality of life in breast cancer patients receiving adjuvant paclitaxel: A three-arm randomized trial.

Abstract

e12051 Background: Breast cancer patients often suffer from fatigue during adjuvant paclitaxel regimen which frequently impairs quality of life (QOL). Therefore, this three-arm randomized controlled study aimed to examine the effects of mindfulness-based stress reduction (MBSR) and progressive muscle relaxation (PMR) on fatigue and QOL in breast cancer patients receiving adjuvant paclitaxel. Methods: Participants were randomly assigned to either a MBSR (n = 20), (PMR) (n = 19) or control group (CG) (n = 15). Participants in the intervention groups were instructed on MBSR and PGE, the steps of interventions were recorded a voice recorder and a WhatsApp group was designed by the principal investigator. Participants were asked to listen the recorded audio files during exercises. The intervention groups continued MBSR or PMR 20 min. each day, totally 12 weeks at their home. The CG received only an attention placebo education on breast cancer. Data collection tools included Brief Fatigue Inventory (BFI) and Functional Living Index-Cancer (FLIC). Data were collected at three time points: baseline (T1), week 12 (T2), and week 14 (T3) for follow-up assessment. Kruskal Wallis tests was used for data analysis. Results: BFI scores were significantly lower in the MBSR, PMR groups compared with the CG at T2 and at T3 (p < .01). As for FLIC scores, there were no significant differences between the study groups at T2 and at T3 (p > 0.05). Conclusions: A brief, MBSR and PMR initiated concurrently with adjuvant paclitaxel regimen decreased fatigue severity. Based on the results, MBSR and PMR can be recommended as supportive therapies for breast cancer patients receiving adjuvant paclitaxel.
