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 breast cancer.

LEARNING OBJECTIVES

• Appreciate the incidence of trophoblast cell surface antigen 2 (TROP2) overexpression in patients with breast cancer, and reflect on the ramifications for prognosis and disease management.
• Consider clinical research data with TROP2-directed antibody-drug conjugates (ADCs) for patients with metastatic breast cancer in order to optimally integrate available agents into routine clinical care.
• Recognize the side effects and toxicities associated with FDA-approved TROP2-directed ADCs used for metastatic breast cancer, and identify strategies to manage and mitigate these complications.
• Evaluate the scientific justification for the use of TROP2-directed ADCs in combination with immune checkpoint inhibitor therapy or in earlier lines of treatment, including the adjuvant setting, and reflect on ongoing trials investigating these approaches.

• Evaluate recently presented clinical research findings to determine their effect on the management of localized and metastatic breast cancer (mBC).
• Appraise published efficacy and safety data from randomized clinical trials evaluating CDK4/6 inhibitors for patients with hormone receptor (HR)-positive localized or metastatic breast cancer, and provide appropriate counsel regarding the optimal use of these agents.
• Recognize the frequency of PIK3CA/AKT1/PTEN alterations and ESR1 mutations in patients with HR-positive, HER2-negative mBC, and employ evidence-based approaches designed to target these aberrations.
• Evaluate published and emerging research to effectively inform the selection and sequencing of available therapeutic agents and regimens for patients with HER2-positive localized and metastatic breast cancer.
• Discuss available research establishing the efficacy of PARP inhibitors for localized or metastatic breast cancer harboring BRCA or other homologous recombination repair pathway mutations, and identify patients for whom treatment with these agents would be appropriate.
• Appreciate the incidence, characteristics and clinical relevance of HER2-low or HER2-ultralow mBC, and understand available research findings with HER2-directed antibody-drug conjugates (ADCs) for these patients.
• Interrogate published and emerging Phase III research documenting the efficacy of TROP2-directed ADCs for patients with mBC to determine the current and potential clinical applicability of these approaches.

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 lung cancer.

LEARNING OBJECTIVES

• Appreciate the biological rationale for and available data with trophoblast cell surface antigen 2 (TROP2)-directed antibody-drug conjugates (ADCs) for EGFR mutation-positive non-small cell lung cancer (NSCLC), and consider the potential role of these agents for appropriately identified patients.
• Understand available clinical research data with the use of TROP2-directed ADCs for NSCLC in patients without actionable genomic alterations, and reflect upon efforts to better distinguish individuals who may benefit from this form of treatment.
• Evaluate the scientific justification for the evaluation of TROP2-directed ADCs in combination with immune checkpoint inhibitors and other available therapies, and counsel patients regarding the potential benefits of participating in clinical research studies investigating these approaches.
• Recognize the spectrum, frequency and severity of toxicities associated with various TROP2-directed ADCs, and understand appropriate strategies to monitor for, manage and mitigate them.

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

LEARNING OBJECTIVES

• Review available research supporting the use of chemotherapy in combination with anti-PD-1/PD-L1 antibodies for newly diagnosed PD-L1-positive metastatic triple-negative breast cancer (mTNBC), and use this information to identify patients who may be appropriate for this approach.
• Evaluate published research findings, clinical factors such as age, performance status, prior therapeutic exposure and HER2-low status and patient preferences in the selection and sequencing of available therapeutic agents for patients with PD-L1-negative TNBC or those who experience disease progression on front-line chemoimmunotherapy.
• Appreciate available clinical trial data with the use of approved antibody-drug conjugates for patients with mTNBC, and determine how to optimally incorporate these agents into current treatment algorithms.
• Recognize the spectrum, frequency and severity of treatment-emergent adverse events associated with agents commonly used in the management of mTNBC, and develop strategies to monitor for, prevent and manage these complications.
• Assess the mechanisms of action of, early data with and ongoing clinical trials evaluating other novel agents and treatment strategies under development for TNBC.

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 breast cancer.

LEARNING OBJECTIVES

• Appreciate the incidence of trophoblast cell surface antigen 2 (TROP2) overexpression in patients with breast cancer and the ramifications for prognosis and management.
• Consider published clinical research data with TROP2-directed antibody-drug conjugates (ADCs) for patients with metastatic breast cancer in order to optimally integrate available agents into routine clinical care.
• Discern the side effects and toxicities associated with FDA-approved TROP2-directed ADCs used in the care of patients with metastatic breast cancer, and identify strategies to manage and mitigate them.
• Evaluate the scientific justification for the use of TROP2-directed ADCs in combination with immune checkpoint inhibitor therapy or in earlier lines of treatment, including the adjuvant setting, and reflect on ongoing trials investigating these approaches.
