Iyengar-yoga compared to exercise as a therapeutic intervention during (neo)adjuvant therapy in women with stage I–III breast cancer: Health-related quality of life, mindfulness, spirituality, life satisfaction, and cancer-related fatigue.

To test the effects of yoga on health-related quality of life, life satisfaction, cancer-related fatigue, mindfulness, and spirituality compared to conventional therapeutic exercises during (neo)adjuvant cytotoxic and endocrine therapy in women with stages I–III breast cancer
In a randomized controlled trial (N =119) (with data from 92 used for data analyses), women with breast cancer undergoing oncological treatment were randomly enrolled in a yoga intervention (YI) (n = 45) or a physical exercise intervention (PEI) (n = 47). Measurements were obtained before (t0) and after the intervention (t1), as well as three months after finishing the intervention (t2) using standardized questionnaires.
PHASE OF CARE: Active antitumor treatment
Randomized, controlled trial with active control
Statistically significant results were found on most functional scales of the EORTC, which indicated the spontaneous recovery of patients’ quality of life after chemotherapy and/or radiation. The global health, role, and social functioning of patients in both groups improved significantly, yet neither group significantly differed from the other in these variables. Fatigue, dyspnea, appetite loss, constipation, and diarrhea improved in both groups. For “nausea and vomiting” and “pain,” significant changes were observed over time. No difference existed in life satisfaction, cancer-related fatigue, spirituality, and mindfulness between the groups.
High drop out rate may be related to the number of measurements. One of the concerns was that patients in treatment were having difficulty with the exercise and yoga programs thought to be from the side effects of the treatment. Further study focusing on one or two areas would be beneficial.
The authors felt that this study may have been accepted by patients post-treatment or by using other forms of yoga. Self-care is becoming more common today, and yoga something you can do for yourself. Further investigation should be conducted to see how effective yoga is for patients with cancer.
