Released November 2017

Video proceedings from a roundtable discussion with Drs Harold J Burstein and Tari King featuring discussion of a comprehensive case-based survey focused on decision-making for patients with ER-positive, HER2-negative early breast cancer, actual patient cases, relevant data sets and ongoing clinical trials.

CE Disclosures and Faculty Information

    This activity is intended for medical oncologists, hematologists, hematology-oncology fellows, general and breast surgeons, surgical oncologists and other healthcare providers involved in the treatment of breast cancer.

    Breast cancer remains the most frequently diagnosed cancer in women, and in 2017 in the United States alone the disease will culminate in an estimated 255,180 new cases and 41,070 deaths. Advances in screening and prevention have resulted in a steady down-stage migration at the time of disease presentation, such that only approximately 5% of patients have identifiable distant metastases at primary diagnosis. The optimal management of localized breast cancer is consequently an essential issue with broad-reaching public health implications.

    ER-positive disease is perhaps the most nuanced of the widely acknowledged breast cancer phenotypes with regard to therapeutic decision-making in the early disease setting, and in recent years tissue-based prognostic and predictive multigene assays designed to estimate the incremental benefit of chemotherapy have been introduced. In addition, controversy exists regarding the indications for neoadjuvant therapy in this patient subset, and heterogeneity is evident in the use of genomic assays in the preoperative setting. Finally, the confirmation of the benefit of extending adjuvant hormonal therapy beyond the traditional 5-year period for select patients has led many clinicians to explore the potential use of prognostic assays to shade decision-making in this regard.

    Although consensus- and evidence-based treatment guidelines are available and aim to assist clinicians with making management decisions in the face of this dynamic clinical and research environment, many areas of controversy persist within academic and community settings. These proceedings from a roundtable conversation centered around the results of a comprehensive case-based survey focused on decision-making for patients with ER-positive/HER2-negative early breast cancer are meant to aid clinicians as they approach the many difficult and challenging situations that arise each day and to ensure that patients with breast cancer receive optimal and evidence-based care.


    • Describe the self-reported practice patterns of medical oncology and surgical experts with regard to the treatment of localized ER-positive, HER2-negative breast cancer, and use this information in the development of up-to-date management recommendations.
    • Appreciate the similarities and differences among existing genomic assays, and use this information to select an appropriate platform or platforms to assess risk and individualize therapy for patients with early breast cancer.
    • Evaluate available and emerging data sets to optimize the use of genomic assays in treatment decision-making for patients with ER-positive, HER2-negative early breast cancer.
    • Consider relevant clinical factors and investigator perspectives in the identification of patients for whom extended endocrine therapy would be a reasonable therapeutic consideration.
    • Implement strategies to increase collaboration between various subspecialists involved in the diagnosis and management of early breast cancer to improve the quality and coordination of patient care.
