Here is a link to the Medscape article I was looking for. You may need to register (for free) to access it. Title: Her-2/neu Gene Amplification in Familial vs. Sporadic Breast Cancer:
http://www.medscape.com/viewarticle/465635
The authors state:
"The study reveals 2 important findings: (1) Her-2/neu gene amplification is more frequent among patients with a family history of breast cancer than in patients with sporadic tumors. (2) Our results indicate that in familial breast cancer, Her-2/neu gene amplification is associated with more aggressive and advanced clinicopathologic features, whereas in sporadic breast cancer, Her-2/neu gene status does not confer significantly different clinical behavior of the disease."
Hopeful
