HER2 Testing Guidelines < Click
The second paragraph states:
The National Comprehensive Cancer Network (NCCN) convened an expert task force after reports of HER2 testing problems encountered in clinical studies involving adjuvant breast cancer therapies.
4 The NCCN Task Force concluded that “
accurate assignment of the HER2 status of invasive breast cancer is essential to clinical decision making in the treatment of breast cancer in both adjuvant (early stage) and metastatic settings.”
