简要总结

Breast cancer (BC) is the most common cancer among women worldwide. Cancer treatments are associated with numerous adverse events that reduce patients' functionality and alter their clinical and molecular profiles. Physical exercise and adherence to nutritional guidelines during treatment and survivorship have been shown to improve recovery prognosis and reduce treatment-related complications. However, the specific effects of prehabilitation, defined as "the process in the cancer continuum that occurs between diagnosis and the start of treatment," remain unknown in BC. A concurrent training program and specific nutritional guidelines during this phase could reduce treatment-related adverse events and improve recovery. Similarly, including a home-based exercise program and nutritional guidelines throughout the cancer treatment continuum could enhance the benefits achieved and improve various aspects of functionality, clinical status, and quality of life. Therefore, the main aim of this randomized controlled trial is to evaluate the impact and effects of a supervised prehabilitation program (combining high-intensity concurrent training and personalized nutritional guidelines) and a supportive care intervention (home-based exercise and personalized nutritional guidelines) on functional, neuromuscular, and cardiorespiratory capacity, quality of life, body composition, and clinical and molecular outcomes in women with BC. In addition, the sustainability of the benefits achieved in the long-term care and the evolution of the outcomes assessed throughout the continuum of cancer treatments will be analyzed.

详细描述

The administration of breast cancer (BC) treatments is associated with various adverse events and acute toxicities that negatively affect molecular, functional, and clinical outcomes in patients with BC. Additionally, these adverse events may reduce treatment tolerance [e.g., relative dose intensity (RDI)], which has been shown to be associated with a worse prognosis in this population. Implementing a high-intensity concurrent training program and specific nutritional guidelines during this phase could reduce adverse treatment events and improve recovery. Likewise, including an unsupervised exercise program and nutritional guidelines during the rest of the cancer treatment may enhance the benefits obtained and improve different outcomes related to the patients' functionality, clinical status, quality of life, and treatment tolerance. Therefore, the aim of this study is to determine the effects of a prehabilitation program (combining high-intensity concurrent training and personalized nutritional guidelines) and a supportive care intervention (home-based exercise and personalized nutritional guidelines) on different outcomes in newly diagnosed women with BC.

This prospective, two-arm parallel randomized controlled trial will be conducted in Valladolid (Castilla y León, Spain). A total of 66 newly diagnosed women with BC will be recruited through medical and diagnostic appointments. Women will be recruited immediately after diagnosis and must be scheduled to receive neoadjuvant chemotherapy or hormone therapy, surgery, or radiation therapy. After completion of baseline study assessments, participants will be randomized to an experimental group or a control group. Participants assigned to the experimental group will undergo a supervised prehabilitation program consisting of structured exercise training and personalized nutritional guidelines, followed by a home-based program during the medical treatment period. Participants in the control group will be asked to continue their usual care and will receive general recommendations for physical exercise and nutrition. Molecular (inflammation-related proteins, epinephrine and norepinephrine), functional (cardiorespiratory fitness, 30-Second Sit-to-Stand Test, Six-Minute Walk Test, handgrip strength and maximal voluntary isometric contraction), clinical (body composition, muscle thickness, and arm volume), and patient-reported (quality of life, upper-limb disability, fatigue, 24-hour nutritional record and food frequency questionnaire) outcomes will be assessed at baseline (week 0) and at various points during the scheduled cancer-associated treatments. Treatment tolerance (relative dose intensity, dose reduction, dose delay, early discontinuation of treatment, and number of patients completing the planned total dose) and treatment-related complications (seroma, infection; hematoma, wound dehiscence, persistent post-surgical pain, lymphedema, neuropathy, and thromboembolism) will be recorded throughout the continuum of treatments.

The change in peak oxygen consumption (ml·kg-¹·min-¹) will be assessed. A Wattbike AtomX cycle ergometer (Wattbike, Nottingham, England) and a stationary gas analyzer (Cortex Metalyzer 3B, Leipzig, Germany) will be used in the study. A gradual incremental exercise protocol will be applied, starting at 50 watts with increments of 25 watts every two minutes, until voluntary exhaustion is reached or medical reasons are presented to end exercise.
