Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: The main objective of the study is to highlight by FES-PET imaging that an anti-HER2 treatment by trastuzumab + pertuzumab can reverse the ERa status in patients with metastatic breast cancer HER2 + and ERa neg.;Secondary Objective: The secondary objectives are: - Evaluate if there is a discrepancy between the RE a neg phenotype determined in immuno-histochemistry and by FES-PET imaging before any treatment. - Study the expression of the ER a by FES-PET imaging according to the tumor metastatic sites before and during the anti-HER2 treatment. - Correlate the fixation obtained between FDG-PET and FES-PET imaging before the start of the treatment. - Correlate the fixation obtained in FES-PET imaging before and during the treatment. - Evaluate the adverse effects of FES-PET imaging.;Primary end point(s): The main judgment criterion is the rate of patients with conversion of FES - lesions in FES + lesions. ;Timepoint(s) of evaluation of this end point: Cycle 3 Day 1 for each patient. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The secondary endpoints are: - The discrepancy rate between the REa neg phenotype determined in immuno-histochemistry and by 18FES-PET imagiging before treatment. - The adverse events due to FES-PET imaging evaluated by the NCI-CTCAE version 4.03. ;Timepoint(s) of evaluation of this end point: Cycle 4 Day 1 for each patient. | — |
