TARGET AUDIENCE
This activity is intended for medical oncologists, breast surgeons, radiation oncologists and other healthcare professionals involved in the diagnosis and treatment of breast cancer.

LEARNING OBJECTIVES

• Evaluate recently presented clinical research findings to determine their effect on the current management of localized or metastatic breast cancer.
• Review published research data supporting the use of chemotherapy or antibody-drug conjugate (ADC) therapy in combination with anti-PD-1/PD-L1 antibodies for localized or metastatic triple-negative breast cancer, and use this information to make appropriate treatment recommendations.
• Appraise published efficacy and safety data from randomized clinical trials evaluating CDK4/6 inhibitors for HR-positive localized or metastatic breast cancer in order to appropriately counsel patients regarding the optimal clinical use of these agents.
• Recognize the frequency of PIK3CA/AKT1/PTEN alterations and ESR1 mutations in individuals with HR-positive, HER2-negative metastatic breast cancer (mBC), and employ evidence-based approaches designed to target these aberrations.
• Understand the mechanism of action of, published research findings with and current and future clinical role of oral selective estrogen receptor degraders for HR-positive localized or metastatic breast cancer.
• Evaluate published research findings to effectively inform the selection and sequencing of available therapeutic agents and regimens for patients with HER2-positive localized and metastatic breast cancer.
• Interrogate published Phase III research findings documenting the efficacy of TROP2-directed ADCs for patients with mBC to determine the current and future clinical applicability of these approaches.
• Assess the mechanisms of action of, early data with and ongoing clinical trials evaluating other novel agents and treatment strategies under development for localized and metastatic breast cancer.

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

LEARNING OBJECTIVES

• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant 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 for hormone receptor (HR)-positive, HER2-negative, ESR1-mutated mBC progressing on standard endocrine therapy in combination with a CDK4/6 inhibitor in order to optimally integrate these agents into the care of appropriately selected patients.
• Review available research data evaluating serial ESR1 testing using circulating tumor DNA to inform early therapeutic switching for patients with HR-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the potential role of this novel strategy.
• Evaluate available clinical trial data with oral SERDs in combination with other systemic therapies (eg, CDK4/6 inhibitors, mTOR inhibitors), and consider the potential role of these regimens.
• Recognize the frequency of PIK3CA/AKT1/PTEN alterations in patients with HR-positive mBC, and employ evidence-based approaches to target these aberrations for appropriate candidates with newly diagnosed and relapsed/refractory disease.
• Understand the biological rationale for the development of agents targeting multiple components of the PI3K/AKT/mTOR pathway, and recognize available and emerging data employing this strategy for patients with HR-positive, PIK3CA wild-type and PIK3CA-mutant mBC.
• Appreciate side effects associated with available and investigational oral SERDs and agents targeting the PI3K/AKT/mTOR pathway, and use this information to develop supportive care plans for patients receiving these treatments.
• Assess ongoing clinical research studies evaluating novel applications of oral SERDs and PI3K/AKT/mTOR inhibitor-based approaches, and counsel patients regarding the potential benefits of trial participation.

TARGET AUDIENCE
This activity is intended for medical oncologists, hematologists, hematology-oncology fellows, radiation oncologists, surgeons and other allied healthcare professionals involved in the treatment of breast cancer.

LEARNING OBJECTIVES

• Understand how various clinical and biological factors, such as age and menopausal status, tumor size and grade and nodal involvement, affect a patient’s risk of recurrence, and use this information to personalize the selection of adjuvant systemic therapy for newly diagnosed hormone receptor (HR)-positive, HER2-negative breast cancer.
• Consider available clinical trial findings with CDK4/6 inhibitors for localized HR-positive, HER2-negative breast cancer, and identify patients for whom adjuvant treatment with one of these agents would be appropriate.
• Recognize adverse events and other common side effects associated with different CDK4/6 inhibitors for localized breast cancer, and tailor therapy for patients with preexisting medical conditions and relevant comorbidities.
• Develop preventive and emergent strategies to reduce or ameliorate the various toxicities associated with CDK4/6 inhibitors.
• Appraise the scientific justification for, available data with and potential clinical role of oral selective estrogen receptor degraders as adjuvant treatment for patients with localized HR-positive, HER2-negative breast cancer.
• Assess the similarities and differences among the various genomic assays with established prognostic and predictive utility in HR-positive localized breast cancer, and consider research findings informing the use of these tests.

TARGET AUDIENCE
This program is intended for medical oncologists, hematologists, hematology-oncology fellows, radiation oncologists, surgeons and other allied healthcare professionals involved in the treatment of cancer.

LEARNING OBJECTIVES

• Effectively apply results of practice-changing clinical research to the care of patients with cancer.
• Appraise the clinical relevance of recent pivotal cancer research published in peer-reviewed journals or presented at major oncology conferences.
• Use an understanding of tumor biomarkers and single and multigene signatures to individualize the care of patients with cancer.
• Educate patients with diverse hematologic cancers and solid tumors about the benefits and risks of new therapeutic agents and strategies.
• Apply an awareness of new datasets and the perspectives of tumor-specific clinical investigators to refine or validate current treatment algorithms.
• Evaluate the mechanisms of action, tolerability and efficacy of promising investigational agents, and consider the implications for clinical practice.
• Recall ongoing trials of therapies for select hematologic cancers and solid tumors, and appropriately refer patients for study participation.
