Is this trial a fit for you?

Likely a good fit

Ideal candidates are women aged 60 and older who have been newly diagnosed with primary breast cancer and have not previously undergone chemotherapy or hormonal treatment.

Probably not a fit

Patients who are younger than 60 or those who have received prior chemotherapy or hormonal treatment may not benefit from this study.

What this trial studies

This observational study aims to assess the impact of systemic therapy on cognitive function in older women diagnosed with breast cancer. It will explore changes in cognitive domains and quality of life, while also examining how genetic factors, inflammatory markers, sleep, and physical measures influence cognitive outcomes. The study is being conducted across multiple national sites, including prominent cancer centers, to gather a diverse patient population. By focusing on older patients, this research seeks to fill a gap in understanding the cognitive effects of cancer treatment in this demographic.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment strategies that minimize cognitive decline in older breast cancer patients.

How similar studies have gone: While there has been preliminary work on cognitive decline in younger breast cancer patients, this study represents a novel approach focusing specifically on older patients.
