Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are women aged 18-65 with histologically-confirmed stage I-III breast cancer who have not yet started chemotherapy.
✕Probably not a fit
Patients who have received neoadjuvant chemotherapy or are scheduled for concurrent radiation therapy may not benefit from this study.

What this trial studies
This observational study aims to explore the relationship between cardiorespiratory fitness (CRF) and cognitive function in breast cancer patients before and after chemotherapy. It will involve a prospective cohort of 50 women who will be assessed for cognitive abilities, physical activity levels, and cancer biomarkers at baseline and three months post-chemotherapy. The study hypothesizes that higher CRF at baseline will correlate with improved cognitive outcomes, specifically in attention, executive function, and memory. Additionally, it will investigate how lifestyle factors and biological markers influence cognitive decline in this population.
Why it matters
Potential benefit: If successful, this study could lead to improved cognitive outcomes for breast cancer patients undergoing chemotherapy through targeted lifestyle interventions.
How similar studies have gone: While there is growing evidence on the impact of lifestyle factors on cancer outcomes, this specific approach examining CRF and cognitive function in breast cancer patients undergoing chemotherapy is relatively novel.
