Guideline recommendations emphasized those changes that would mitigate false positives, particularly relating to issues of specimen fixation and pathologist interpretation.39,43-47 Preliminary data from an ongoing prospective study seem to suggest that the frequency of false-positive test results may have diminished, in that the concordance between local testing in laboratories throughout the United States and confirmatory central HER2 testing at the Mayo Clinic (Rochester, MN) for the ALTTO (Adjuvant Lapatinib and/or Trastuzumab Treatment Optimization HER2 Adjuvant Trial) trial showed that less than 6% of patients initially considered eligible were not subsequently centrally confirmed as being HER2 positive.48.

The major signaling pathways activated by EGFR receptors are mediated by Ras-Raf-MAPK, JNK, PI3 kinase, and PLC and result in a plethora of biological functions [7, 8]. Because many newly diagnosed patients are under emotional stress and/or may be unaccustomed to complex medical terminology, the use of easily understood language (at an educational level that the patient can understand) is key to clear communication.
