Evaluating the impact of fitness trackers on fatigue during breast cancer treatment

Randomisierte Studie Zum Nutzen Des Fitnesstracker Basierten Aktivitätstrainings während Einer Adjuvanten Bestrahlung Des Mammakarzinoms (OnkoFit I)

Not applicable Interventional University Hospital Tuebingen · NCT04506476

This study is testing whether using fitness trackers to help breast cancer patients exercise can reduce their fatigue during treatment compared to just reading about physical activity.

What this trial studies

This randomized three-arm trial investigates the effects of an activity tracker-based exercise program on cancer-related fatigue in breast cancer patients undergoing adjuvant radiotherapy. Participants will be assigned to different arms, with some receiving fitness tracker training and others receiving informational booklets about physical activity during cancer therapy. The study aims to assess the quality of life and fatigue levels using the FACIT Questionnaire three months post-treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a diagnosis of breast cancer who are scheduled for adjuvant radiotherapy.

Not a fit: Patients with severe cardiovascular conditions or those who cannot engage in physical activity may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help reduce fatigue and improve quality of life for breast cancer patients undergoing radiotherapy.

How similar studies have performed: Other studies have shown promising results with exercise interventions during cancer treatment, suggesting potential benefits of this approach.
