Brief summary
This longitudinal pre-post study evaluates the effects of a 12-week community-based multimodal intervention combining supervised physical exercise and health education in women with metastatic breast cancer receiving active systemic treatment. The intervention includes Nordic walking, Tai Chi, and structured health education workshops. The main outcomes are changes in health-related quality of life and cancer-related fatigue, assessed before and after the intervention using validated EORTC questionnaires.Mostrar más líneas
Detailed description
Women with metastatic breast cancer receiving active systemic treatment frequently experience impaired health-related quality of life, cancer-related fatigue, and limitations in daily functioning. Supportive care strategies that combine physical exercise, education, and symptom self-management may help improve these outcomes, although evidence in women living with metastatic breast cancer remains limited. This study is a longitudinal pre-post intervention study conducted in women with metastatic breast cancer receiving active systemic treatment. Eligible participants are women with metastatic breast cancer, preserved functional status, and the ability to ambulate independently. Participants are assessed at baseline and after completion of the intervention. The intervention lasts 12 weeks and consists of a community-based multimodal program combining supervised physical exercise and health education. The exercise component includes two 60-minute supervised sessions per week: one session of Nordic walking and one session of Tai Chi. Nordic walking sessions are supervised by a physiotherapist, and Tai Chi sessions are led by a trained instructor. Exercise sessions are adapted to participants' physical capacity and clinical condition. In addition to the exercise component, participants attend structured health education workshops throughout the program. These sessions address topics relevant to women with metastatic breast cancer, including general aspects of metastatic breast cancer, systemic treatments and toxicity management, the benefits of physical exercise, nutrition and supplementation, sleep hygiene, emotional regulation, communication with the social environment, and aesthetic care during cancer treatment. Health-related quality of life is assessed using the EORTC QLQ-C30 and the breast cancer-specific EORTC QLQ-BR45 questionnaires. Cancer-related fatigue is assessed using the EORTC QLQ-FA12 questionnaire. The study evaluates changes in global health status, functional domains, fatigue dimensions, and selected breast cancer-specific symptom and functional domains before and after the intervention. The aim of the study is to determine whether a supervised, community-based multimodal program combining physical exercise and health education is associated with improvements in quality of life, functioning, and fatigue-related outcomes in women with metastatic breast cancer receiving active systemic treatment.
Interventions
OTHERMultimodal Oncology-Based Intervention for Metastatic Breast Cancer
Participants receive a 12-week community-based multimodal oncology intervention combining supervised physical exercise and health education. The exercise component consists of one weekly Nordic walking session and one weekly Tai Chi session, each lasting 60 minutes. In addition, participants attend structured health education workshops covering metastatic breast cancer, systemic treatment and toxicity management, safe physical exercise, nutrition, sleep hygiene, emotional regulation, communication, and aesthetic care during cancer treatment. The intervention aims to promote physical and emotional well-being, support self-management, and improve quality of life.

Masking description
No masking was applied. Due to the nature of the community-based physical exercise and health education intervention, participants and intervention providers could not be blinded to group assignment. Outcome assessments were performed before and after the intervention.Mostrar más líneas
