Official title
SPECT/CT Imaging of Different Types of HER2 Expression in Breast Cancer Using Technetium-99m-labelled Affibody [99mTc]Tc -ZHER2:4107
Overview
The study should evaluate the \[99mTc\]Tc -ZHER2:4107 accumulation in primary tumour of breast cancer patients with different HER2 expression
Detailed description
To determine different HER2 expression in primary breast cancer patients before any system or local treatment.
Interventions
- Drug Injection of [99mTc]Tc-ZHER2:4107, SPECT/CT
One single injection of \[99mTc\]Tc-ZHER2:4107, followed by SPECT/CT imaging 2 hours after injection
Primary outcome measures
- [99mTc]Tc -ZHER2:4107 uptake in primary breast tumor [Time frame: 2 hours]
- [99mTc]Tc -ZHER2:4107 background uptake [Time frame: 2 hours]
- Tumor-to-background ratio [Time frame: 2 hours]
Secondary outcome measures (1)
- Differentiation of HER2 expression in primary tumors [Time frame: 2 hours]
