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

• Appreciate the incidence and clinical implications of ESR1 mutations in endocrine-resistant metastatic breast cancer, 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 available and investigational oral SERDs for ESR1-mutated ER-positive, HER2-negative metastatic breast cancer progressing on standard endocrine therapy with a CDK4/6 inhibitor in order to optimally integrate these agents into patient care.
• Evaluate available clinical trial data with oral SERDs in combination with other therapeutic agents for patients with and without ESR1 mutations, and consider the potential role of these regimens.
• Appreciate the side effects associated with available and investigational oral SERDs, and use this information to develop supportive management plans for patients undergoing treatment with this form of therapy.
• Assess ongoing clinical research evaluating novel applications of oral SERDs for ER-positive breast cancer, and counsel patients regarding the potential benefits of trial participation.

• Appreciate the incidence of trophoblast cell surface antigen 2 (TROP2) overexpression in patients with breast cancer, and reflect on the ramifications for prognosis and management.
• Consider available clinical research data with TROP2-directed antibody-drug conjugates (ADCs) for patients with metastatic breast cancer (mBC) in order to optimally integrate available agents into routine clinical care.
• Discern the side effects and toxicities associated with FDA-approved TROP2-directed ADCs for patients with mBC, 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.

TARGET AUDIENCE
This program 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 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.
• 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 oncologists, hematology-oncology fellows and other healthcare providers involved in the treatment of extrapulmonary neuroendocrine carcinoma.

LEARNING OBJECTIVES

• Appreciate the incidence, etiology and clinical and biological characteristics of extrapulmonary neuroendocrine carcinoma (EP-NEC).
• Consider published research findings guiding the current selection and sequencing of therapy for patients with EP-NEC.
• Appraise the scientific rationale for targeting delta-like ligand 3 (DLL3) in EP-NEC, and recognize the mechanism of action of DLL3 x CD3-targeting T-cell engagers.
• Evaluate available research findings with DLL3 x CD3 T-cell engagers for patients with EP-NEC, and consider the potential clinical role of these agents.
• Recognize the spectrum, frequency, and severity of adverse events associated with DLL3 x CD3 T-cell engagers, such as cytokine release syndrome, neurologic toxicity, infections and cytopenias, and appreciate strategies for prevention, amelioration and management.
• Recall ongoing trials evaluating novel DLL3-targeted approaches for EP-NEC, and appropriately counsel patients regarding enrollment.

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

LEARNING OBJECTIVES

• Appreciate the pathophysiology of ocular toxicities associated with the administration of specific anticancer therapies for various solid tumors and hematologic cancers.
• Understand the frequency and severity of ocular toxicities observed in pivotal trials evaluating novel agents and strategies demonstrating efficacy in various tumor types, and educate patients about to begin therapy with these approaches regarding the potential development of these adverse events (AEs) and what to do if they are suspected.
• Recall strategies commonly employed to identify, manage and mitigate ocular toxicities in patients receiving anticancer treatment, and use this information to appropriately intervene when these side effects are suspected or diagnosed.
• Appraise the role of multidisciplinary specialists such as ophthalmologists and other eye-care professionals in the diagnosis and management of ocular toxicities, and effectively collaborate with these clinicians to offer best-practice care for patients at high risk for or with a suspected or confirmed diagnosis of these AEs.

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.
