The 3-year DISCO study aims to systematically implement physical activity in breast cancer patients. The primary objective is to investigate the efficacy of a connected device (personalized non-supervised exercise program including a wristband as activity tracker, a smartphone application, and a website) and the efficacy of a therapeutic education program on the physical activity level of patients at the end of the 6-month programs. The research hypothesis is that patients participating in the intervention with the connected device or in the therapeutic education program will achieve the international recommendations in terms of physical activity, compared to women receiving only physical activity recommendations.
Rationale: In women with breast cancer, weight gain, obesity, and lack of physical activity have been shown to increase the risk of comorbidities and deleterious long-term outcomes. Despite the safety of physical activity and the benefits of physical activity performed concomitant to treatment on fatigue, quality of life, and possibly survival, its implementation is not systematic in the cancer care pathway. Methods: The DISCO study is a randomized, controlled, multicenter intervention study that will be conducted among 432 women treated for localized breast cancer. Patients will be randomly assigned to one of the four arms of the study according to a 1:1:1:1 ratio. * Women allocated to the "connected device" arm will benefit from a 6-month personalized exercise program consisting of three weekly sessions of aerobic and strength exercises, carried out autonomously with a connected device (wristband, smartphone application, website). * Women allocated to the "therapeutic education" arm will follow a 6-month program of therapeutic patient education. * Women allocated to the "combined" arm will benefit from both interventions in parallel. * Women allocated to the "control" arm will receive standard care, i.e., international recommendations on physical activity. Evaluations will be conducted at inclusion (T1, baseline), 6 months (T2, end of interventions), and 12 months (T3, 12 months post-inclusion to study maintenance of behavior change) on the following parameters: level of physical activity and sedentary behavior (RPAQ self-administered questionnaire), physical condition assessed by functional tests (6-min walking test, sit-to-stand test, hang-grip test, sit-and-reach flexibility test, single-leg balance test), anthropometrics (weight, height, waist circumference, hip circumference, calculated body mass index), body composition (fat mass, lean body mass, fat free mass, water), biological factors (blood sample at baseline and 6 months), lifestyle factors (tobacco status, alcohol intake), psychological factors (quality of life assessed by the EORTC QLQ-C30 / BR-23 questionnaire, health-related quality of life assessed by the EQ-5D-5L questionnaire, fatigue assessed by the PFS-12 questionnaire), socio-economic parameters (social deprivation assessed by the EPICES questionnaire, level of education, family situation, professional status assessed through a self-administered questionnaire). Clinical data will be obtained from patients' medical records. Acceptability of connected device and of therapeutic education program will be assessed within the population. The medico-economic impact of the interventions will be evaluated through cost-utility and cost-effectiveness analyses. Data will be recorded using an e-CRF. Women will be recruited over 2 years and will be followed up for 12 months. Hypothesis: The research hypothesis is that patients participating in the 6-month intervention with the connected device or in the 6-month therapeutic education program will be more likely to achieve the international recommendations in terms of physical activity, compared to women receiving only physical activity recommendations. Expected results are to identify best modalities to implement exercise during and after breast cancer treatment. In a public health perspective, the challenge is to reduce geographical, social, and organizational inequalities among patients to practice regular physical activity and to promote the systematic integration of physical activity in routine cancer care.

Women will receive a connected wristband (https://www.carefitness.com/) and a subscription to a smartphone application and website (http://disco.biomouv.com/). They will have to participate in a 6-month personalized non-supervised exercise program consisting of 3 weekly sessions of 20 min to 1-hr of moderate-to-vigorous physical activity (≥3 METs): 2 sessions of brisk walking and 1 session of muscle strengthening. Women should wear the wristband daily to track their number of steps (automatic Bluetooth synchronization to the application). Duration and intensity of sessions and target number of daily steps will progressively increase (+15% up to 10,000 steps) to place the patients in a progression dynamic. Women will receive phone-based follow-up at 1 week, 2 months, and 4 months.
Women will be invited to participate in the 6-month therapeutic patient education program "Mieux manger, mieux bouger" ("Eat better, move better") elaborated at the Léon Bérard cancer center. The program consists in four sessions: * a 1-hour individual session of "educational diagnosis" to assess their needs and establish a contract of objectives, * two "educational sessions" of 1h30 each using tools, in group of 10 patients maximum to improve their daily practice of physical activity, * a 1-hour individual session of "educational assessment" to evaluate whether their objectives were reached.
