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

• Assess available Phase III data with HER2-directed antibody-drug conjugate (ADC) therapy as a component of neoadjuvant therapy for patients with high-risk localized breast cancer, and consider the current clinical role of this novel treatment approach.
• Evaluate current research evidence with HER2-directed ADC therapy for patients with HER2-positive localized breast cancer and residual disease after neoadjuvant treatment.
• Appraise available research data and relevant clinical and biological factors guiding the selection of first-line therapy for patients with newly diagnosed HER2-positive metastatic breast cancer (mBC).
• Review published research supporting TROP2-directed ADC therapy in combination with anti-PD-1/PD-L1 antibodies for triple-negative mBC, and use this information to make appropriate treatment recommendations.
• Evaluate published clinical research findings with TROP2-directed ADC monotherapy for HR-positive and triple-negative mBC, and optimally incorporate these agents into clinical care.
• Assess the biological rationale for the evaluation of HER2-directed ADCs for HER2-low and HER2-ultralow mBC, and identify patients appropriate for this treatment approach.
• Discern the side effects and toxicities associated with FDA-approved ADCs in the care of patients with breast cancer, and identify strategies to manage and mitigate these complications.
• Recall ongoing trials evaluating the potential role of novel ADC-based strategies in the localized and metastatic settings, and appropriately counsel patients with breast cancer regarding enrollment.

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

• Appreciate the incidence and clinical relevance of human epidermal growth factor receptor 2 (HER2) mutations and protein overexpression in non-small cell lung cancer (NSCLC), and consider the implications for biomarker assessment and current clinical management.
• Evaluate published research findings along with patient clinicopathologic variables to individualize the selection and sequencing of therapy for patients with HER2-mutant NSCLC.
• Recognize the spectrum, frequency, and severity of toxicities associated with HER2-targeted tyrosine kinase inhibitors and antibody-drug conjugates with established activity in lung cancer in order to facilitate the safe and effective use of these agents.

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

LEARNING OBJECTIVES

• Assess the clinical and biological characteristics of endometrial cancer, and consider their implications for therapeutic decision-making.
• Appreciate the efficacy and toxicity profiles of anti-PD-1/PD-L1 antibodies approved for the treatment of metastatic endometrial cancer, and weigh this information in selecting the optimal treatment regimen for patients.
• Evaluate the current role of neoadjuvant immunotherapy in the management of localized endometrial cancer, and educate patients with localized disease regarding the benefits and risks of this approach.

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

LEARNING OBJECTIVES

• Assess the clinical and biological characteristics of the various histologic subtypes and molecular subgroups of endometrial cancer, and consider the implications for prognosis and therapeutic decision-making.
• Evaluate the importance of microsatellite instability (MSI) and mismatch repair (MMR) deficiency assessment in the management of endometrial cancer, and adapt current testing practices to optimally identify patients with corresponding genetic abnormalities.
• Appreciate available clinical research findings with anti-PD-1/PD-L1 antibodies in combination with chemotherapy as first-line treatment for advanced or recurrent endometrial cancer, and educate patients with MSI-high/MMR-deficient or microsatellite-stable/MMR-proficient disease about this novel strategy.
• Understand the biological rationale for and available data with PARP inhibitors in combination with immune checkpoint inhibitor therapy for advanced or metastatic endometrial cancer.
• Recognize adverse events associated with immune checkpoint inhibitor-based approaches used in the treatment of endometrial cancer, in order to educate patients and manage complications.

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

• Analyze the biological basis for the investigation of immune checkpoint inhibitors for patients with localized non-small cell lung cancer (NSCLC), and evaluate available data documenting the efficacy and safety of anti-PD-1/PD-L1 antibodies as neoadjuvant and/or adjuvant therapy.
• Appraise available findings from clinical studies and real-world analyses documenting long-term outcomes with anti-PD-L1 antibody consolidation therapy for patients with unresectable Stage III NSCLC who have not experienced disease progression after standard platinum-based chemotherapy concurrent with radiation therapy, and optimally integrate this treatment approach into patient care.
• Recall available clinical trial findings with EGFR tyrosine kinase inhibitors for nonmetastatic EGFR-mutated NSCLC, and identify patients for whom treatment with this novel approach would be warranted.
• Evaluate published clinical research data with ALK-directed therapy as adjuvant treatment for localized ALK-positive NSCLC, and apply this information in the care of appropriately selected patients.
• Recall the design of ongoing clinical trials evaluating novel investigational strategies for localized and locally advanced NSCLC, and appropriately counsel patients about availability and participation.
