Although most major cancer organizations agree on the guidelines for prostate cancer screening, there is still uneven application of the test, such as in the older patient population, resulting in overdiagnosis and waste in an already fiscally challenged health-care system. Researchers from the...
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 ...
FORMAL DISCUSSANT Joaquin Mateo, MD, PhD, of the Prostate Cancer Translational Research Group, Vall d’Hebron Institute of Oncology, Barcelona, said that the TRITON2 findings were encouraging, although still preliminary. “We should interpret these results with caution, because this interim analysis ...
THE SEARCH for biomarkers in prostate cancer has proved frustrating, partly due to the complexity of the disease and its heterogeneity.
