研究概览
简要总结
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.

结局指标
主要结局
The evaluation of diagnostic performance of 68Ga-DOTA-dPNE PET in breast cancer
时间窗: through study completion, an average of 1 year
Patients with histologically proven breast cancer will be prospectively recruited in this study. They will receive 68Ga-DOTA-dPNE and 18F-FDG. The detection rates of lesions, bones and lymph nodes (visual) were compared.
