Insomnia affects about 60% of the patients treated with radio-chemotherapy, a percentage twice higher compared to that observed in the general population. This sleep disorder increases cancer-related fatigue (CRF), the side effect most often reported by patients. Conversely, it is well accepted that adapted physical activity (APA) improves tolerance to treatment, decreases the risk of recurrence, increases survival, and reduces CRF. The present study aims to evaluate, in non-metastatic breast cancer patients, the composition and architecture of sleep by ambulatory polysomnography and to verify the effects of an APA rehabilitation program (3 times a week during 12 weeks), on the quality and quantity of sleep, daytime sleepiness. The biological markers: melatonin and body temperature will be studied to better understand the chronobiological mechanisms of the sleep-wake rhythm. Finally, the physiological responses to exercise, pain, CRF and finally quality of life will be studied at the beginning, at the end of the program and at a distance from it. Improved sleep-wake rhythm by a physical activity may reduce CRF, prevent recurrence and comorbidities.
