AbstractApproximately 70% of breast cancers are estrogen-receptor positive. Tamoxifen and aromatase inhibitors have been the mainstay of endocrine therapy and have improved breast cancer survival. However, a large number of patients experience disease recurrence either during or following completion of endocrine therapy. Recent improvements in our understanding of the various mechanisms underlying the development of endocrine resistance have led to a dramatic change in the landscape of current endocrine treatment with the introduction of new drugs targeting molecular pathways involved in endocrine resistance. Over the past...

ConclusionsWomen who received NET had similar rates of BCS compared to women who received NAC. Those who received NET for longer treatment durations had increased odds of BCS and downstaging compared to women who did not receive neoadjuvant therapy.

Breast cancer is one of the leading causes of cancer related deaths in women worldwide. The disease is extremely heterogenous. A large percentage of the breast cancers are dependent on estrogen signaling and hence respond to endocrine therapies which essentially block the estrogen signaling. However, many of these tumors emerge as endocrine resistant tumors. Many mechanisms have been proposed to explain the emergence of endocrine resistance, which include mutations in the estrogen receptors, cross-talk with other signaling pathways, cancer stem cells etc. This review is focused on the role of non-canonical estrogen recepto...

Authors: Fedele P, Sanna V, Fancellu A, Cinieri S Abstract Introduction: The dysregulation of cell cycle control can lead to cancer development. In breast cancer, cyclin D, CDK 4,6 and the retinoblastoma protein play a central role in the control of cell proliferation, in crosstalk with the estrogen receptor and Her2 pathways. Although the mechanisms by which the CDK4/6 complex is involved in the control of cell growth in triple negative breast cancer (TNBC) are still unclear, some TNBCs might be sensitive to CDK4/6 inhibitors. Areas covered: The authors provide an overview of the treatments that target cell cycle ...

This study examined the efficacy of a structured group intervention during adjuvant endocrine therapy for obese patients with breast cancer. The intervention involved a combination of proper nutrition, exercise, and group coaching. METHODS: Participants were patients with breast cancer who were undergoing adjuvant endocrine therapy and exhibited apparent weight gain while undergoing therapy, or had a diagnosis of abnormal lipid metabolism. We conducted a single-arm prospective study with a combined intervention. The intervention comprised 15 min of nutrition education, a 30-min group health coaching program, and three...

When William Stewart Halsted described the radical mastectomy in 1894, it was thought that a cure for breast cancer lay in maximally invasive and often morbid surgery. Our understanding of breast cancer has changed immeasurably in the subsequent century in which innumerable preclinical and clinical studies have demonstrated that advanced breast cancer is a systemic disease that requires a multimodality approach that includes both local (surgery and radiation) and systemic therapies (chemotherapy, endocrine therapy, and/or immunotherapy).
