Unlike ordinary tiredness, cancer-related fatigue may persist despite rest and can negatively affect physical functioning, psychological well-being, daily activities, and quality of life. Exercise has been recognized as an important supportive strategy for the management of cancer-related fatigue; however, adherence to conventional exercise programs during intensive cancer treatment may be challenging.\n\nDance-based exercise represents a multimodal form of physical activity combining aerobic exercise, coordination, balance, rhythmic movement, and social and cognitive engagement. Its enjoyable and adaptable nature may provide an alternative approach to maintaining physical activity during cancer treatment. Nevertheless, evidence regarding the effects of structured dance-based exercise during neoadjuvant treatment for breast cancer remains limited.\n\nThis randomized controlled study will investigate the effects of a structured dance-based exercise intervention in women with breast cancer undergoing neoadjuvant treatment. The study is designed to determine whether incorporating supervised dance-based exercise into the period of neoadjuvant treatment can reduce cancer-related fatigue and support physical and psychosocial functioning compared with standard oncological care alone.\n\nThe intervention is structured as a progressive, supervised dance-based exercise program delivered during neoadjuvant treatment. The program combines dance-based aerobic activity with movements targeting coordination, mobility, balance, and muscular function. Exercise intensity and complexity will be individually adapted according to participants' physical condition, exercise tolerance, and treatment-related symptoms. This approach is intended to maintain an appropriate exercise stimulus while allowing flexibility in response to changes in health status during oncological treatment.\n\nIn addition to evaluating the clinical and functional effects of the intervention, the study includes an exploratory mechanistic component. Cancer treatment and physical activity may influence systemic metabolism, inflammatory processes, and the intestinal microbial ecosystem. The study will therefore investigate changes in the gut microbiome and selected circulating biological markers and explore their relationships with changes in fatigue, physical fitness, body composition, physical activity, and other clinical and functional characteristics.\n\nThe gut microbiome component will characterize microbial composition and diversity using stool samples collected during the study. Blood-based analyses will complement the microbiome assessment by examining selected biological pathways potentially involved in the response to exercise and cancer treatment. Integrating these biological data with functional and patient-reported data may provide insight into mechanisms through which exercise influences health and recovery during neoadjuvant breast cancer treatment.\n\nThe longitudinal design will also allow the investigators to examine whether changes observed during the intervention period are maintained during recovery following surgery. By combining a randomized exercise intervention with clinical, functional, behavioral, and biological assessments, the study aims to provide a comprehensive evaluation of dance-based exercise as a supportive strategy during neoadjuvant treatment for breast cancer.",[49,55],{"label":50,"type":51,"description":52,"interventionNames":53},"Dance-Based Exercise Intervention","EXPERIMENTAL","Participants receive standard neoadjuvant oncological treatment and participate in a supervised 12-week dance-based exercise program.",[54],"Other: Dance-Based Exercise Program",{"label":56,"type":57,"description":58,"interventionNames":39},"Standard Care Control","NO_INTERVENTION","Participants receive standard neoadjuvant oncological treatment without participation in the structured dance-based exercise program.",[60],{"type":6,"name":61,"description":62,"armGroupLabels":63,"otherNames":39},"Dance-Based Exercise Program","Participants will complete a 12-week supervised dance-based exercise program consisting of three 60-minute sessions per week.
