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

LEARNING OBJECTIVES

• Counsel patients with newly diagnosed metastatic EGFR-mutated non-small cell lung cancer (NSCLC) regarding available therapeutic considerations, explaining the relevance of mutation type, symptomatology, sites and extent of metastases, prior therapeutic exposure and other factors.
• Appreciate the biological rationale for dual inhibition of MET and EGFR for patients with EGFR-mutated NSCLC, and understand recently presented data establishing the benefit of this strategy.
• Evaluate the documented efficacy of chemotherapy combined with EGFR-targeted therapy, and consider the current role of available approaches in both the front-line and relapsed/refractory settings for patients with metastatic NSCLC and EGFR mutations.
• Review published research findings with TROP2-directed antibody-drug conjugates for patients with metastatic NSCLC and EGFR mutations, and optimally incorporate these agents into treatment algorithms.
• Appraise the scientific rationale for the development of bispecific antibodies directed at PD-1 x VEGF, and reflect on the potential role of these agents in the management of EGFR-mutated NSCLC.
• Recall the biological rationale for the evaluation of various novel therapeutic approaches for patients with NSCLC and EGFR mutations.

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 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.
