Exercise program for breast cancer patients undergoing chemotherapy

Randomized Controlled Trial of Simultaneous Exercise During Neo-/Adjuvant Chemotherapy in Breast Cancer Patients and Its Effects on Neurocognition

Not applicable Interventional Johannes Kepler University of Linz · NCT04789187

This study is testing if a high-intensity exercise program can help breast cancer patients undergoing chemotherapy improve their thinking skills and reduce cognitive decline.

What this trial studies

The ECCO-Study evaluates the effectiveness of a high-intensity exercise program during neo/adjuvant chemotherapy in breast cancer patients, focusing on its impact on cognitive function. This randomized controlled trial will assess cognitive performance through neuropsychological tests and MRI volumetry, while also measuring inflammatory biomarkers associated with cancer-related cognitive impairment (CRCI). The study aims to provide evidence on whether exercise can mitigate cognitive decline during chemotherapy, which affects a significant number of breast cancer patients.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-70 with histologically confirmed breast cancer who are scheduled for neo- and adjuvant chemotherapy.

Not a fit: Patients with significant comorbid conditions, prior cognitive impairments, or those unable to participate in physical activity will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve cognitive function and quality of life for breast cancer patients undergoing chemotherapy.

How similar studies have performed: While evidence for the positive effects of exercise on CRCI is still lacking, recent studies suggest a growing interest in this area, indicating potential for success.
