Investigational drug(s) / intervention(s)

18F-FAPI-04 PET scan

18F-FAPI-04 PET scan: FAPI-04, labeled with PET radio-nuclide 18F will be used as a molecular imaging tracer for PET scan. All participants will undergo 18F-FAPI-04 PET scan.

Study summary

This study aims to evaluate the diagnostic accuracy (sensitivity, specificity, positive/negative predictive value, and overall accuracy) of 18F-FAPI-04 PET imaging in breast cancer for detecting fibroblast activation protein (FAP)-rich lesions. Additionally, the study will longitudinally monitor dynamic changes in FAP expression levels and tumor size during therapy, including chemotherapy, targeted therapy, or immunotherapy.The non-invasive nature of 18F-FAPI-04 PET addresses limitations of traditional biopsy-dependent stromal evaluation, offering whole-body quantification of tumor microenvironment dynamics to optimize therapeutic decision-making.
