Multimodal Prehabilitation Program That Combines Physical Exercise, Psychological Intervention and Nutritional Support to Improve the Response to Neoadjuvant Chemoterhapy in Early Breast Cancer Patients

Summary

The aim of this clinical trial is to evaluate whether following a multimodal prehabilitation program including physical exercise, nutritional support and psychological intervention during neoadjuvant chemotherapy in breast cancer patients could improve the pathological response to chemotherapy. 214 women with non-metastatic breast cancer with indication of chemotherapy before surgery will be eligible to participate. Patients will be randomly assigned to either the intervention group or the control group. * 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. * Patients assigned to the control group (107 women) will undergo standard clinical management for their disease without multimodal prehabilitation. The 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.
