Anxiolytic effects of a yoga program in early breast cancer patients undergoing conventional treatment: a randomized controlled trial.

OBJECTIVES

This study compares the anxiolytic effects of a yoga program and supportive therapy in breast cancer outpatients undergoing conventional treatment at a cancer centre.

METHODS

Ninety-eight stage II and III breast cancer outpatients were randomly assigned to receive yoga (n=45) or brief supportive therapy (n=53) prior to their primary treatment i.e., surgery. Only those subjects who received surgery followed by adjuvant radiotherapy and six cycles of chemotherapy were chosen for analysis following intervention (yoga, n=18, control, n=20). Intervention consisted of yoga sessions lasting 60min daily while the control group was imparted supportive therapy during their hospital visits as a part of routine care. Assessments included Speilberger's State Trait Anxiety Inventory and symptom checklist. Assessments were done at baseline, after surgery, before, during, and after radiotherapy and chemotherapy.

RESULTS

A GLM-repeated measures ANOVA showed overall decrease in both self-reported state anxiety (p<0.001) and trait anxiety (p=0.005) in yoga group as compared to controls. There was a positive correlation between anxiety states and traits with symptom severity and distress during conventional treatment intervals.

CONCLUSION

The results suggest that yoga can be used for managing treatment-related symptoms and anxiety in breast cancer outpatients.
