What this trial studies

This observational study aims to assess the efficacy of 18F-Fluoroestradiol (18F-FES) PET/CT imaging in evaluating estrogen receptor (ER) expression levels in patients with primary and metastatic breast cancer. The study focuses on understanding the heterogeneity of estrogen receptors and their role in treatment response and pharmacokinetics of estrogen receptor-targeted therapies. By utilizing a highly sensitive and specific imaging tracer, the study seeks to provide insights into the biological characteristics of breast cancer and improve treatment strategies for patients. Participants will undergo PET/CT scans to measure ER levels, contributing to a better understanding of breast cancer pathology.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old with pathologically confirmed breast cancer.

Not a fit: Patients who are pregnant or have severe underlying diseases that prevent cooperation with PET examination may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance personalized treatment approaches for breast cancer patients by providing better insights into estrogen receptor status.

How similar studies have performed: Other studies utilizing PET imaging for evaluating estrogen receptors in breast cancer have shown promising results, indicating potential for success in this approach.
