Test the Diagnostic Accuracy of the HER2 Imaging Using the Labelled Monoclonal Antibody Trastuzumab by Correlating the HER2 PET/CT Imaging With the FDG-PET/CT and Molecular Characterization of Tumor Samples With Discordant Image Findings [ Time Frame: 4 years ]
A visual 'patient-based' classification capturing the whole disease burden was developed by using a side-by-side display, comparing baseline FDG-PET/CT(showing all FDG-positive mets independent of their HER2-imaging status) & day4 HER2-PET/CT. Pts were grouped into 4 HER2-PET/CT patterns according to the proportion of FDG avid tumour load showing relevant 89Zr-T uptake. Pattern A: entire tumor load showed pertinent tracer uptake; B: dominant part of tumour load showed tracer uptake; C: minor part of tumor load showed tracer uptake; D: entire tumor load lacked tracer uptake. Patterns A+B='HER2-positive' & C+D='HER2-negative'. In the 20 pts: 4 pts were classified "A", 5"B", 1"C" & 10"D". This classification indicates substantial heterogeneity of 89Zr-T uptake within this so called 'HER2-positive' pt population. After dichotomization, 11(55%) pts were considered as HER2-PET/CT negative. Furthermore, HER2-PET/CT revealed intrapatient heterogeneity of tumour uptake(pts classified B or C).

Pilot Imaging Study With 89Zr-Trastuzumab in HER2-positive Metastatic Breast Cancer Patients
Pilot Imaging Study With 89Zr-Trastuzumab in HER2-positive Metastatic Breast Cancer Patients : Correlation With FDG-PET/CT and Anatomopathological Results
Evaluation of the diagnostic potential of HER2 imaging using zirconium 89 labelled trastuzumab.

This is the first belgian feasibility study of HER2 imaging using a labelled monoclonal antibody, namely trastuzumab labelled with zirconium 89.

The aims of this study are:

I/ Evaluate the diagnostic potential of HER2 imaging using zirconium 89 labelled trastuzumab (based on the Groningen experience), through the analysis of the correlation between the FDG-PET/CT and the HER2 immunoPET.

II/ PET quantification of HER2 receptor by using the images and the blood pharmacokinetic of the tracer.

III/ In the subset of patients for whom biopsies of metastatic sites have not been carried out previously and are of an easy access, tissue will be acquired as part of the validation of the HER2 immunoPET and as an attempt to better understand the molecular heterogeneity of HER2 positive breast cancer at the time of relapse.

IV/Evaluate the concentration of circulating HER2 extracellular domain in the blood and study his possible role as on imaging quality

  3. Patients with FDG-PET positive metastatic lesions.
  4. Brain metastases are allowed provided they are controlled and they are not the sole site of metastatic disease.
  5. Patient planned to have metastatic site biopsy for HER2 status control.
  6. Age ≥ 18 years
  7. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 to 1
  8. For women of childbearing potential a pregnancy test will be done and an agreement to use a highly-effective non hormonal form of contraception.
  9. Agreement from the patient to participate in this imaging study and if indicated agreement to biopsy one or two accessible lesions.
