Examining blood components in young and elderly breast cancer patients

Age-Related Peripheral Blood Components and Their Association With Treatment Efficacy in Breast Cancer Patients: An Observational Cohort Study

Observational Fudan University · NCT06718010

This study looks at the blood of young and older women with a specific type of breast cancer to see if certain blood components can help predict how well younger patients will do during treatment.

What this trial studies

This observational study aims to compare peripheral blood components between young and elderly patients with HR+HER2- breast cancer undergoing neoadjuvant therapy. It will analyze both retrospective data from existing medical records and prospective data collected during routine clinical treatment. The goal is to identify blood components that may influence the prognosis of younger patients with this specific type of breast cancer. The study will continue until patients complete their neoadjuvant therapy and undergo surgery.

Who should consider this trial

Good fit: Ideal candidates are female patients aged 18 years or older with histologically confirmed HR+HER2- breast cancer requiring neoadjuvant therapy.

Not a fit: Patients with distant metastasis or severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help tailor treatment strategies for young HR+HER2- breast cancer patients based on their blood component profiles.

How similar studies have performed: While similar studies have explored blood components in cancer prognosis, this specific focus on age-related differences in HR+HER2- breast cancer is relatively novel.
