E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of the study is to highlight by FES-PET imaging that an anti-HER2 treatment by trastuzumab + pertuzumab can reverse the ERα status in patients with metastatic breast cancer HER2 + and ERα neg. |
L’objectif principal de l’étude est de mettre en évidence par TEP-18FES, qu’un traitement anti-HER2 par trastuzumab + pertuzumab peut reverser le statut REα chez des patientes présentant un cancer du sein métastatique HER2+ et REα neg. |
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are:
- Evaluate if there is a discrepancy between the RE α neg phenotype determined in immuno-histochemistry and by FES-PET imaging before any treatment.
- Study the expression of the ER α 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. |
Les objectifs secondaires sont les suivants :
- Evaluer s’il existe avant tout traitement, une discordance entre le phénotype REα neg déterminé en immuno-histochimie et par TEP-18FES.
- Etudier l’expression du REα en TEP-FES selon les sites métastatiques tumoraux avant et pendant le traitement anti-HER2.
- Corréler la fixation obtenue entre TEP au FDG et TEP au FES avant le début du traitement.
- Corréler la fixation obtenue en TEP-FES avant et pendant le traitement.
- Evaluer les effets indésirables de la TEP-18FES. |
