Stephen R.D. Johnston, MD, PhD, of The Royal Marsden NHS Foundation Trust, discusses phase III study findings from the global monarchE trial, which showed that when added to standard adjuvant endocrine therapy, abemaciclib is the first CDK4/6 inhibitor to improve invasive disease–free survival in hormone receptor–positive high-risk early breast cancer (Abstract LBA5_PR). Read more on the monarchE trial in the Journal of Clinical Oncology.
Erika P. Hamilton, MD, of Sarah Cannon Research Institute, discusses results of the nextMONARCH study, which indicated that combining abemaciclib with tamoxifen improved overall survival. Dr. Hamilton also details adverse events in different arms of the study (Abstract 273O).

In a phase II trial reported in JAMA Oncology, Sara M. Tolaney, MD, MPH, and colleagues found that the addition of pembrolizumab to eribulin did not improve progression-free survival in women with hormone receptor (HR)-positive, HER2-negative metastatic breast cancer. As stated by the...
In individual participant data and trial-level meta-analyses reported in JAMA Network Open, Gulia et al found that disease-free survival with adjuvant trastuzumab given for less than 1 year was noninferior to 1 year of trastuzumab therapy in patients with early breast cancer. In addition, the...
Although most patients with breast cancer are considered to have an overall excellent prognosis, 600,000 people still die annually of the disease around the world.
