TARGET AUDIENCE
This activity has been designed to meet the educational needs of oncology nurses, nurse practitioners and clinical nurse specialists involved in the treatment of breast cancer.

PURPOSE STATEMENT
By providing information on the latest research developments in the context of expert perspectives, this NCPD activity will assist oncology nurses, nurse practitioners and clinical nurse specialists with the formulation of state-of-the-art clinical management strategies to facilitate optimal care of patients with breast cancer.

DESIRED LEARNING OUTCOME
At the conclusion of this activity, the learner will be able to self-report understanding of the logistical and practical requirements associated with novel therapies for breast cancer in order to educate, counsel and assist patients and their families in decision-making.

At the end of the activity, learners will also be able to

• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant hormone receptor (HR)-positive metastatic breast cancer (mBC), and determine optimal strategies to effectively identify patients harboring these abnormalities.
• Understand the biological rationale for, mechanism of action of and pharmacologic similarities and differences among available and investigational oral selective estrogen receptor degraders (SERDs).
• Interrogate published research documenting the efficacy of oral SERD monotherapy in patients with HR-positive, HER2-negative mBC with ESR1 mutations who experience disease progression on standard endocrine therapy in combination with a CDK4/6 inhibitor, in order to optimally understand the role of these agents in patient care.
• Review available research findings with serial ESR1 testing using circulating tumor DNA as a means to inform early therapeutic switching for patients with HR-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the clinical applicability of this novel strategy.
• Evaluate available clinical trial data with oral SERDs in combination with other systemic therapies, such as CDK4/6 inhibitors or mTOR inhibitors, and consider the potential role of these regimens.
• Appraise the scientific justification for, available data with and potential clinical role of oral SERDs as adjuvant treatment for patients with localized HR-positive, HER2-negative breast cancer.
• Appreciate side effects associated with available and investigational oral SERDs, and use this information to develop supportive management plans for patients receiving this form of therapy.
