Human epidermal growth factor receptor (HER 2) is amplified in 25 to 30% of breast cancer patients and those whose tumors demonstrate HER 2 gene amplification and protein overexpression have an inferior prognosis manifested by shorter disease-free and overall survival. Trastuzumab, the humanized murine anti-HER 2 monoclonal antibody, inhibits tumor growth when used alone and has synergistic and additive effects when used with chemotherapeutic agents (paclitacel-doxorrubicine). At the present time, the accurate diagnostic assessment of HER 2 is essential for appropriate application of the humanized anti HER 2 monoclonal antibody, trastuzumab, for the treatment of patients with metastatic breast cancer. FDA has approved its use for patients with metastatic breast cancer with HER 2 over-expression since 1998, as a first line treatment in association with paclitaxel or as a second or third line monotherapy. In Argentina, two Consensus Meetings of HER 2 Diagnosis have taken place: the first one on May 15th, 2002 and the second on April 11th, 2003, supported by Roche Laboratories (Herceptin). In this paper, some topics of these meetings are reviewed. Our single-public center experience is discussed.
