HER2 is the target of the monoclonal antibody trastuzumab (marketed as Herceptin). Trastuzumab is effective only in cancers where HER2 is over-expressed. One year of trastuzumab therapy is recommended for all patients with HER2-positive breast cancer who are also receiving chemotherapy. [33] Twelve months of trastuzumab therapy is optimal.
HER2-type, which are positive for over-expression of the HER2 receptor. ER and PR can be positive or negative. This subtype receives targeted therapy. Basal-type, or Triple Negative (TN), which are negative for all three major receptor types; Additional classification schema are used for prognosis and include histopathology, grade, stage, and ...
In early-stage HER2-positive breast cancer, trastuzumab-containing regimens improved overall survival (Hazard ratio (HR) = 0.66) and disease-free survival (HR = 0.60). [39] Increased risk of heart failure (RR = 5.11) and decline in left ventricular ejection fraction ( relative risk RR = 1.83) were seen in these trials as well. [ 39 ]
Early detection critical to long-term breast cancer survival. The ongoing OlympiA trial involves more than 1,800 adults diagnosed with gBRCAm, HER2-negative high-risk early breast cancer, early ...
When a tumor is “triple positive,” that means that its growth is fueled by both estrogen and progesterone hormones, as well as a protein called human epidermal growth factor receptor 2 (HER2).

The prognosis of the most common form of invasive carcinoma NST is intermediate. Regardless of the histological subtype, the prognosis of IDC depends also on tumor size, presence of cancer in the lymph nodes, histological grade, presence of cancer in small vessels (vascular invasion), expression of hormone receptors and of oncogenes like HER2/neu.
The five-year survival for patients with a diagnosis of stage 4 melanoma was less than 5% before 2010, and now clinical trials have shown that more than 50% of patients are still alive 10 years ...
