Because of their well-established efficacy, inhibitors of cyclin-dependent kinases 4 and 6 (CDK4/6) are the standard of care in the treatment of hormone receptor–positive, HER2-negative metastatic breast cancer. The question now is this: after disease progresses on a CDK4/6 inhibitor and endocrine...

About 80% of triple-negative breast cancers are classified as the subtype basal-like. Typically, patients with triple-negative breast cancer receive chemotherapy before surgery. The presence of residual cancer in the breast after chemotherapy signals a higher likelihood that the cancer will...
In a study led by researchers at NYU Langone Health and its Perlmutter Cancer Center involving more than 3,000 women treated for breast cancer at the height of the COVID-19 pandemic in New York City, only 64 patients, or 2% of the total study population, contracted the virus. Of this group, 10 died ...
