Breast Cancer

On April 4, 2019, the US Food and Drug Administration (FDA) expanded the indication of palbociclib (Ibrance; Pfizer), a kinase inhibitor, in combination with specific endocrine therapies for men with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer. This is the first hormonal-based therapy to be approved for men.
On March 27, 2019, the US Food and Drug Administration (FDA) issued an alert from its Office of Women’s Health announcing that, after more than 20 years of regulatory oversight, the agency is proposing amendments to the existing policy governing mammography services.
Triple-negative breast cancer is considered one of the most difficult to treat breast cancers, with few treatment options, but finally a breakthrough study shows progress by extending patient survival.
Recent results with the investigational targeted therapy alpelisib, a PI3K inhibitor, showed impressive clinical benefits. Adding alpelisib to fulvestrant (Faslodex) extended progression-free survival (PFS) compared with endocrine therapy alone in patients with hormone receptor (HR)–positive, HER2-negative advanced breast cancer characterized by a PIK3CA mutation.
Chicago, IL—The current standard of care for women with early, HER2-positive breast cancer is 12 months of trastuzumab (Herceptin). Analysis of the phase 3 randomized clinical trial PERSEPHONE showed that 6 months of treatment with trastuzumab was noninferior to 12 months in terms of disease-free survival.
A new study presented at the 2018 American Association for Cancer Research meeting suggests that HER2 mutations can be acquired during metastatic cancer and their development represents a previously unreported mechanism of resistance to treatment.

Dr Thomas Bachelot is careful to set reasonable expectations for his patients with HR+/HER2- metastatic breast cancer regarding how long their treatment will last and how it will impact them.
Hope Rugo, MD, discusses common presenting symptoms of HR+/HER2- metastatic breast cancer, citing bone metastasis as the most prevalent.
Breast cancer is one of the most common cancer diagnoses in the United States. The National Cancer Institute estimates that 252,710 American women will be diagnosed with breast cancer and 40,610 will die from the disease in 2017. For the majority (62%) of women with breast cancer, the disease is confined to the breast, and the 5-year survival approaches 100%. However, for women with metastatic disease, the likelihood of survival at 5 years drops to 27%.
