Metastatic Breast Cancer: One Size Does Not Fit All Clifford Hudis, M.D.Chief, Breast Cancer Medicine Service MSKCC
We define invasive breast cancer on the basis of 2 genes: ER and HER2
We have to consider the genome of the tumor AND the patient.
Apoptosis genes (n=641) Cytoskeleton genes (n=641)

Molecular profiles are: Variable by population studied Poorly adapted for clinical use Biology as yet not well characterized Relationship to conventional chemotherapy response not well characterized Ability to correctly identify molecular targets not yet proven Challenges
