Patients will be randomly assigned to either the intervention group or the control group.\n\n* Patients assigned to the intervention group (107 women) will undergo a directed multimodal prehabilitation program during the chemotherapy (4-6 months), including structured physical exercise, psychological intervention and nutritional guidance.\n* Patients assigned to the control group (107 women) will undergo standard clinical management for their disease without multimodal prehabilitation.\n\nThe response to chemotherapy between the two groups will be evaluated and compared. It is expected that multimodal prehabilitation will increase the response to chemotherapy and will improve the postoperative recovery of patients and their quality of life, as well as reducing the number of complications from surgery and chemotherapy treatment. Changes in the tumor microenvironment are also expected after prehabilitation.', 'detailedDescription': "Breast cancer (BC) is the most common neoplasm worldwide and the leading cause of death among women. Neoadjuvant chemotherapy (NACT) is currently one of the main therapeutic pillars. The pathological response after NACT has demonstrated prognostic value in BC, being also a determinant factor for posterior treatments. In recent years, research has increasingly focused on the impact of lifestyle changes on BC, such as physical exercise, diet, and psychological interventions. These actions are part of what is known as prehabilitation, defined as the set of strategies applied prior to surgery to optimize the physical and emotional condition of patients before the surgical intervention.\n\nThe individual application of these strategies in BC patients has shown improved oncological outcomes, with positive effects on quality of life and tolerance to medical treatments. Furthermore, evidence suggests that these interventions may favorably modulate the tumor microenvironment by reducing intratumoral hypoxia, enhancing antitumor immune responses, and modulating systemic pro-inflammatory states.\n\nDespite the demonstrated benefits of prehabilitation in multiple medical and surgical fields, there is limited evidence regarding its impact on systemic treatment outcomes in BC patients. There is also a lack of solid evidence evaluating the role of multimodal prehabilitation (combining different prehabilitation strategies) in BC, as well as its effect on treatment response and tolerance.\n\nThe current study proposes the application of a multimodal prehabilitation program during the NACT window, based on structured physical exercise, psychological therapy (mindfulness or anxiety-control techniques), and nutritional counseling in BC patients, as a strategy to enhance treatment response through changes in the tumor microenvironment. Additionally, it will be assessed whether the intervention improves treatment tolerance and postoperative recovery, among others.\n\nThe study consists of a randomized, single-blind, controlled clinical trial with two parallel groups that will include 214 women diagnosed with non-metastatic breast cancer, eligible for NACT, and awaiting surgery at our center.\n\nParticipants will be randomized into two parallel groups in a 1:1 ratio (control and intervention group, including 107 women each). A basal evaluation will be performed in all patients before starting NACT, reporting their physical, nutritional and psychological status, as well as a tumor microenvironment study in the diagnostic biopsy sample. All patients will undergo 4-6 months of NACT, the control group with standard clinical management and the intervention group following the multimodal prehabilitation program. After NACT, the physical, nutritional and psychological status of all patients will be re-evaluated. Patients will undergo surgery according to their disease and the pathological response to the treatment will be assessed.\n\nThe primary outcome will be the pathological response after NACT in both groups, assessed through the Residual Cancer Burden (RCB) index. Secondary outcomes will include NACT tolerance, quality of life, psychological and nutritional status, postoperative recovery, tumor microenvironment changes and patients' physical condition.\n\nThe group of BC patients undergoing the multimodal prehabilitation program during NACT is expected to achieve better response rates (RCB 0 and I) than the control group. Furthermore, the multimodal intervention is anticipated to promote quantitative and/or qualitative changes in the tumor microenvironment, improve NACT tolerance, enhance quality of life, and optimize postoperative recovery and the patients' physical, psychological, and nutritional status."}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Histologically confirmed diagnosis of non-metastatic breast cancer: stages cT1-T4, cN0-N3, M0, and candidates for neoadjuvant chemotherapy (NAC).\n* Age ≥ 18 years.\n* Signed informed consent.\n\nExclusion Criteria:\n\n* Contraindication or physical inability to perform moderate-to-high intensity physical exercise.\n* Pregnant or breastfeeding patients.\n* Presence of other active synchronous neoplasms.\n* Metastatic breast cancer (stage IV).\n* Patients already engaging in regular physical exercise: more than 150 minutes of moderate or intense aerobic exercise per week.\n* Male breast cancer patients.\n* Personal history of a previous malignancy treated with chemotherapy.\n* Severe or poorly controlled psychiatric illness (including uncontrolled active substance abuse).'}, 'identificationModule': {'nctId': 'NCT07107594', 'acronym': 'DIANA', 'briefTitle': 'Multimodal Prehabilitation Program That Combines Physical Exercise, Psychological Intervention and Nutritional Support to Improve the Response to Neoadjuvant Chemoterhapy in Early Breast Cancer Patients', 'organization': {'class': 'OTHER', 'fullName': 'Hospital Clinic of Barcelona'}, 'officialTitle': 'Multimodal Intervention During Neoadjuvant Chemotherapy in Patients With Early-breast Cancer as a Strategy to Improve Treatment Response: DIANA Trial (Multimodal Prehabilitation: DIet, ANxiety Control Psychotherapy, Physical Activity)', 'orgStudyIdInfo': {'id': 'HCB/2023/1036'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'NO_INTERVENTION', 'label': 'Control', 'description': '107 women that will follow the standard of care.
