Application of 68GA-labeled CD73 Targeting Probe PET/CT Imaging in the Diagnosis of Breast Cancer
The investigators plan to conduct a 68Ga-DOTA-dPNE PET/CT imaging study in breast cancer patients to observe the binding of the tracer to tumor lesions and evaluate CD73 expression. As part of the study design, a subset of patients will initially undergo dynamic PET/CT imaging to evaluate the safety profile and pharmacokinetic distribution of the radiotracer in vivo. Subsequently, static PET/CT imaging will be performed on additional patients to assess the diagnostic effectiveness of 68Ga-DOTA-dPNE. Imaging…

About this study
The investigators plan to conduct a 68Ga-DOTA-dPNE PET/CT imaging study in breast cancer patients to observe the binding of the tracer to tumor lesions and evaluate CD73 expression. As part of the study design, a subset of patients will initially undergo dynamic PET/CT imaging to evaluate the safety profile and pharmacokinetic distribution of the radiotracer in vivo. Subsequently, static PET/CT imaging will be performed on additional patients to assess the diagnostic effectiveness of 68Ga-DOTA-dPNE. Imaging results will be correlated with relevant clinical indicators to evaluate the potential of this tracer in diagnosing breast cancer, guiding therapeutic decisions, and predicting responses to targeted therapies.
Interventions
- Drug: 68GA-DOTA-dPNE — Patients with breast cancer receive intravenously 68GA-DOTA-dPNE followed by PET/CT after 40min of injection
Primary outcomes
- The evaluation of diagnostic performance of 68Ga-DOTA-dPNE PET in breast cancer (through study completion, an average of 1 year)
Eligibility information
