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.
• 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.

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.
• 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 activity is intended for medical oncologists, radiation oncologists, surgeons, hematology-oncology fellows and other healthcare providers involved in the treatment of lung cancer.

LEARNING OBJECTIVES

• Appraise available findings from clinical research investigating anti-PD-1/PD-L1 antibody consolidation for limited-stage small cell lung cancer (SCLC) in patients who have not experienced disease progression after standard platinum-based chemotherapy concurrent with radiation therapy, and determine the appropriate clinical role of this approach. 
• Review long-term data supporting the use of anti-PD-1/PD-L1 antibodies in combination with platinum-based chemotherapy as first-line therapy for patients with extensive-stage SCLC, and consider how these regimens can be appropriately and safely integrated into clinical practice.
• Appreciate the biological rationale for the evaluation of maintenance treatment after chemoimmunotherapy induction for extensive-stage SCLC, and assess available research findings with and the current role of this therapeutic approach.
• Evaluate available clinical trial findings with FDA-approved agents for patients with SCLC who experience disease progression on or after platinum-containing first-line therapy, and determine how to optimally integrate these therapies into current treatment algorithms.
• Appreciate the incidence of B7-H3 overexpression in patients with SCLC, and develop an understanding of the rationale for, available data with and ongoing studies of B7-H3-directed antibody-drug conjugates for relapsed/refractory disease.  
• Assess ongoing clinical research studies evaluating other novel agents and treatment strategies under development for the management of SCLC, and counsel patients regarding the potential benefits of trial participation.
