Summary
Brief summary (as posted)
This study aims to evaluate the clinical utility of 18F-labeled HER2 Affibody PET for diagnosing and monitoring HER2-expressing breast cancer. HER2, a protein overexpressed in certain malignancies including breast cancer, serves as a critical biomarker for targeted therapies.The HER2 Affibody-an engineered 7 kDa protein with nanomolar affinity for HER2-leverages its rapid tumor penetration and clearance kinetics to achieve high-contrast PET imaging. This study aims to evaluate the diagnostic efficacy of 18F-HER2 Affibody PET in early detection, clinical staging, and treatment response monitoring, thereby providing novel imaging evidence to guide personalized therapeutic strategies for patients with HER2-expressing breast cancer.
