Her-2/neu gene amplification and over-expression in stomach and esophageal adenocarcinoma: from pathology to treatment

Crit Rev Oncol Hematol. 2012 Jun;82(3):310-22. doi: 10.1016/j.critrevonc.2011.06.003. Epub 2011 Jul 23.

Abstract

Discovery of the over-expression of Her-2/neu or the amplification of its regulatory gene in stomach and esophageal cancer has resulted in targeted treatment directed at this protein. The fact itself and its consequences have been the topic of an abundance of studies and clinical trials. In the present report we review the current state of the art as regards diagnosis of the over-expression and amplification of Her-2/neu, its inhibition as a new therapeutic concept, treatment toxicity, and the development of resistance to Her-2/neu as a limiting factor in stomach and esophageal adenocarcinoma.
