Developments in the Management of Metastatic HER2-Positive Breast Cancer: A Review.

Approximately 20% of breast cancers overexpress human epidermal growth factor receptor 2 (HER2), providing an actionable target for many different therapies. In the metastatic setting, prognosis has improved greatly with the use of anti-HER2 drugs such as trastuzumab, pertuzumab, and trastuzumab-emtansine. In the third line setting and beyond, several emerging treatments have shown benefits, including novel small molecule targeted agents and antibody-drug conjugates.

Chronic obstructive pulmonary disease (COPD) is the only major worldwide cause of mortality that is currently increasing in prevalence.
