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.",[24,25],"Breast Cancer","Breast Cancer, HER2-Expression","RECRUITING","2025-04-27",{"date":29,"type":30},"2025-04-30","ACTUAL",{"date":32,"type":30},"2025-04-09",{"date":34,"type":20},"2027-12",{"name":36,"class":37},"The Affiliated Hospital of Qingdao University","OTHER"]
