e13075 Background: The safety, feasibility and benefit of physical activity is robust in adjuvant breast cancer, but as far as we know, there is little information on the feasibility and benefit of exercise in women with advanced breast cancer. The objective of our study is to analyze the feasibility and impact on fatigue, quality of life and functionality of an individualized, prospective and supervised exercise program in a group of patients with metastatic breast cancer. Methods: A prospective study on 30 metastatic breast cancer patients who were recruited as volunteers between February 2018 and April 2019 by Medical Oncologists from the Medical Oncology Unit at University Clinical Hospital Virgen de la Victoria (Malaga, Spain). Participants included in this study were patients aged between 34 and 71 years old and all had metastatic breast cancer, not amenable to curative treatment. The intervention was a twelve-week Therapeutic Exercise and Education Programme delivered by a physiotherapist. The intervention was preceded by a physical assessment of the musculoskeletal system. The outcomes were cancer-related fatigue, quality of life and functional outcomes (patient- reported and other measured by investigators). Results: Of the 30 patients initially recruited, only 11 of them completed the program with an attendance greater or equal to 17 sessions (75% of assistance). Most of patients who dropped (19), did it because of personal matters, not related to disease progression. Regarding patients who completed the completion of physical activity program (n = 11), the majority were treated on first line of treatment with hormonal receptors positive tumors and bone metastasis. After the intervention, no major changes were observed in cancer-related fatigue, quality of life and several patients-reported outcomes, although an improvement in functionality was observed, in investigator-measured parameters (30-STS and adapted burpees). Conclusions: Our study shows that a supervised and individualized tailored physical activity program in metastatic breast cancer patients is safe and feasible, although more studies are needed to analyse its impact on improving functional parameters, fatigue and quality of life.
