Understanding how chemotherapy affects cognitive function in breast cancer patients

Longitudinal Pilot Mechanistic Study of the Effects of Chemotherapy on Cognitive Function in Breast Cancer Patients and Non-Cancer Control Participants - Optional Sub-Study: Research Brain MRI

Observational University of Rochester · NCT03137095

This study looks at how chemotherapy affects thinking and memory in newly diagnosed breast cancer patients compared to people without cancer.

What this trial studies

This observational study enrolls newly diagnosed breast cancer patients who are about to start chemotherapy, along with age-matched control participants, to investigate the prevalence of cognitive difficulties associated with chemotherapy. Participants will undergo a series of cognitive assessments and blood draws over approximately five months to explore the biological mechanisms behind these cognitive challenges. An optional sub-study includes research brain MRIs to further examine brain function and structure in relation to cognitive performance. The study aims to provide insights into how chemotherapy impacts cognitive health in cancer patients compared to the general population.

Who should consider this trial

Good fit: Ideal candidates are females aged 21 and older with a diagnosis of invasive non-metastatic breast cancer scheduled to begin chemotherapy.

Not a fit: Patients with psychiatric illnesses, neurodegenerative diseases, or those currently hospitalized may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better understanding and management of cognitive difficulties in breast cancer patients undergoing chemotherapy.

How similar studies have performed: Other studies have explored cognitive effects of chemotherapy, but this specific approach focusing on biological mechanisms is relatively novel.
