Shedding Light on Mechanisms of Resistance to Treatment of Metastatic Castration-Resistant Prostate Cancer
ONE OF the pressing issues in metastatic castration-resistant prostate cancer is the development of resistance to therapies directed at the androgen receptor (AR), such as enzalutamide (Xtandi) and abiraterone acetate (Zytiga). Research is ongoing to identify mechanisms of resistance in the hope of ...
Management of HER2-Positive Breast Cancer: Business as Usual?
MANAGEMENT OF HER2-positive breast cancer changed after the introduction of trastuzumab (Herceptin), the first anti-HER2 therapy to be approved by the U.S. Food and Drug Administration (FDA) for this type of cancer. Recent studies have more clearly defined the role of pertuzumab (Perjeta) and...
PARP Inhibitor Active in BRCA1/2-Mutated Metastatic Castration-Resistant Prostate Cancer
THE SEARCH for biomarkers in prostate cancer has proved frustrating, partly due to the complexity of the disease and its heterogeneity.
