Feasibility Study: Yoga Educational Project

Not Applicable

Completed

• Conditions: Breast Cancer
• Interventions: Behavioral: educational yoga program

• Registration Number: NCT04001751
• Lead Sponsor: Institut du Cancer de Montpellier - Val d'Aurelle

Brief Summary

As much as 45 to 60% of patients treated with hormonotherapy (HT) for breast cancer (BC) suffer from osteoarticular pain during treatment. Secondary effects have become a real issue because of their consequences on the patients' quality of life, but also on treatment efficacy and survival when they induce dose reduction or premature withdrawal of treatment.

Additional medicines (acupuncture, hypnosis, yoga) have become more and more popular these last years. 48 to 80% of patients with BC eventually choose them. A review comparing efficacy of various therapies to decrease osteoarticular pain concludes to a highest efficacy of anti-inflammatory treatments, paracetamol and yoga.

With this project, the investigators will assess the feasibility of a therapeutic yoga program with home practice for patients with breast cancer treated with hormonotherapy. The investigators will measure adhesion of the patients to perform yoga postures in an autonomous manner. Our study will also allow collection of data on the effect of such a program on quality of life, in view of setting-up an intervention study.

Detailed Description

Numerous initiatives have started in France, often associative. It is essential to evaluate in a rigorous manner, these therapies before making them part of the patient's care pathway.

Yoga has shown a real benefit in terms of pain reduction in patients with BC treated with HT. These osteoarticular pains are the secondary effect on which a physical therapeutic care can have a real benefit.

It thus appears innovative to complete this care with a therapeutic education program (TEP) in postural yoga which will enable patients to practice yoga postures at home by themselves. Yoga allows a large adaptation to pains expressed by each patient. It will favor the development of the feeling of control that they have in particular on their pain. participants will so improve the self-efficacy, the quality of life, and will reduce their fatigue and their pain. The patients involved have already lived major body transformations because of the disease and treatments. Yoga will help them put their lives together again, both physically and psychologically, and reclaim their body.

Studies have shown the short-term effects of yoga practice on anxiety, stress, pain and quality of life. Few rare studies have suggested that patients could add yoga practice at home to the supervised sessions, but these studies lacked therapeutic patient education. To date, to our knowledge, no data on the effect of the realization of yoga postures at home on increase of the patients' self-competency feeling are available in France. Also, the long-term effects of such programs need to be assessed.

The Montpellier Cancer Institute (ICM) has set-up 8 years ago yoga sessions for women with breast cancer, together with an association located in Montpellier.

With this study, the investigators will assess the feasibility of an educational yoga program given by a trained physical therapist in patients with beast cancer treated with hormonotherapy.

Arm && Interventions

Group	Intervention	Description
Therapeutic educational postural yoga program	educational yoga program	Daily 15-min yoga sessions at home during 12 weeks. One 90-min yoga-therapeutic education session/week (during 6 weeks).

Primary Outcome Measures

Name	Time	Method
proportion of patient compliance to the educational yoga program	12 weeks	Compliance will be posittive if 70% of daily sessions at home and 4 sessions out of the 6 therapeutic educational (TEP) sessions delivered in the center by a physical therapist are realised

Secondary Outcome Measures

Name	Time	Method
To assess quality of life by Quality of Life Questionnaire specify for Breast Cancer	12 weeks	Quality of life will be measured by EORTC QLQ-Br23 (Quality of Life Questionnaire specify for Breast Cancer)
the patients' satisfaction towards the program	12 weeks	Satisfaction will be measured using the Likert scale (0 no satisfy to 10: strongly satisfy)
the induced self-competency feeling	12 weeks	self-competency feeling induced will be assessed using the GSES (General Self Efficacy-Schwarzer) questionnaire (10 questions - scale 1- not at all true to 4-totally true)
Osteoarticular pain	12 weeks	osteoarticular pain will be assessed using a Visual Analogous scale (0: no pain to 10: maximum pain)
Compliance to hormonotherapy treatment	12 weeks	Taking hormonotherapy treatments will be reported in a log-book by the patients.
Reasons of non-participation to the study.	at baseline	The reason of non-participation to the study (difficulty of coming, not concerning by the project, not interesting by the project, fatigue, other) will be reported by the patient to the doctor.
To assess quality of life by Quality of Life Questionnaire	12 weeks	Quality of life will be measured by EORTC QLQ-C30 (Quality of Life Questionnaire)
To assess fatigue and stress	12 weeks	Fatigue and stress will be assessed using a Visual Analogous Scale (VAS) (0: no fatigue or no stress to 10 - maximum fatigue or stress)
Forward-flexion flexibility	12 weeks	Forward-flexion flexibility is defined by the distance between the fingertips and the floor. It will be measured with a ruler.
Respiratory capacity	12 weeks	Respiratory capacity will be measured with a spirometer
Anxiety and depression prevalence	12 weeks	Anxiety and depression will be assessed by HADS (Hospital Anxiety and Depression Scale) questionnaire (7 questions about Anxiety and 7 questions about Depression)
