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 and clinical implications of ESR1 mutations in endocrine-resistant metastatic breast cancer (mBC), 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 between available and investigational oral selective estrogen receptor degraders (SERDs).
• Interrogate published research documenting the efficacy of oral SERD monotherapy for ER-positive, HER2-negative, ESR1-mutated mBC progressing on standard endocrine therapy in combination with a CDK4/6 inhibitor to optimally integrate these agents into the care of appropriately selected patients.
• Review available research data evaluating the role of serial ESR1 testing using circulating tumor DNA as a means to inform early therapeutic switching for patients with hormone receptor-positive mBC receiving CDK4/6 inhibitor-based first-line therapy, and consider the potential role of this novel strategy in treatment.
• Evaluate available clinical trial data with oral SERDs in combination with other systemic therapies (eg, CDK4/6 inhibitors, mTOR inhibitors), and consider the potential role of these regimens in disease management.
• Appreciate side effects associated with available and investigational oral SERDs, and use this information to develop supportive care plans for patients undergoing treatment with this form of therapy.
• Assess ongoing clinical research studies evaluating novel applications of oral SERDs for ER-positive breast cancer, and counsel patients regarding the potential benefits of trial participation.

TARGET AUDIENCE
This program is intended for medical oncologists, hematology-oncology fellows, surgeons and other healthcare providers involved in the treatment of colorectal cancer (CRC).

LEARNING OBJECTIVES

• Understand the incidence and prognostic and clinical relevance of microsatellite instability (MSI)/mismatch repair (MMR) deficiency in patients with localized colorectal cancer (CRC), and consider the implications for molecular testing and care.
• Evaluate the biological rationale for the use of immune checkpoint inhibitors in the care of patients with localized MSI-high (MSI-H)/MMR-deficient (dMMR) CRC, and provide counsel regarding available clinical evidence and guideline-endorsed treatment recommendations.
• Optimize the current and future use of neoadjuvant therapy for patients with localized and locally advanced CRC, considering the influence of various clinical and biological factors, including MSI/MMR status.
• Appreciate published research documenting the efficacy and safety of anti-PD-1/PD-L1 antibody therapy added to standard adjuvant chemotherapy for Stage III MSI-H/dMMR colon cancer, and counsel patients regarding the potential role of this novel therapeutic approach.
• Recognize the clinical relevance of circulating tumor DNA (ctDNA) as a prognostic and predictive biomarker in CRC, and comprehend the rationale for its use in detecting molecular residual disease in patients.
• Appreciate published datasets documenting the clinical utility of ctDNA testing in risk stratification, surveillance and treatment decision-making for patients with CRC, and consider the current and future role of this strategy in personalizing treatment.
• Recall ongoing trials evaluating novel agents and strategies for patients with nonmetastatic CRC, and use this information to refer candidates for study participation.

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

LEARNING OBJECTIVES

• Appraise available Phase III data documenting the comparative efficacy and tolerability of first- and second-generation Bruton tyrosine kinase (BTK) inhibitors, and consider the implications of these findings for clinical decision-making for patients with newly diagnosed chronic lymphocytic leukemia (CLL).
• Appreciate the scientific rationale for the investigation of combined BTK and Bcl-2 inhibition, and review recently presented data documenting the safety and efficacy of this strategy for patients with CLL.
• Discuss available clinical research demonstrating the efficacy and safety of noncovalent BTK inhibitors for CLL, and consider the current and future role of these agents for patients with newly diagnosed and relapsed/refractory disease.
• Implement a plan of care to recognize and manage side effects and toxicities associated with covalent and noncovalent BTK inhibitors commonly employed in the treatment of CLL.
• Recall ongoing research studies attempting to further define the optimal role of BTK inhibitor-based strategies in therapy for CLL, and appropriately counsel patients regarding potential clinical trial participation.

TARGET AUDIENCE
This program is intended for medical oncologists, hematology-oncology fellows, surgeons and other healthcare providers involved in the treatment of gastroesophageal cancers.

LEARNING OBJECTIVES

• Describe published research data with immune checkpoint inhibitors alone or in combination with other systemic therapies in the management of metastatic gastric, gastroesophageal junction (GEJ) and esophageal cancers, and optimally integrate these strategies into nonresearch treatment algorithms.
• Assess available data with monoclonal antibody therapy directed at claudin 18.2 (CLDN18.2) in combination with chemotherapy as first-line treatment for patients with HER2-negative, CLDN18.2-positive gastric or GEJ cancer, and optimally incorporate this approach into management algorithms.
• Review published and emerging research findings with HER2-targeted therapies for patients with HER2-positive gastroesophageal cancers, and assess the current and future role of various agents and regimens.
• Evaluate the scientific justification for the dual targeting of PD-1 and TIGIT for patients with gastroesophageal cancers, and appreciate available data with this novel approach.
• Appreciate the rationale for, available data with and ongoing research studies evaluating novel targeted and immunotherapeutic strategies for gastroesophageal cancers to enhance clinical trial participation for appropriately identified patients.

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

LEARNING OBJECTIVES

• Describe published research data with immune checkpoint inhibitors alone or in combination with other systemic therapies in the management of metastatic gastric, gastroesophageal junction (GEJ) and esophageal cancers, and optimally integrate these strategies into current treatment algorithms.
• Assess available data with approved and investigational Claudin 18.2 (CLDN18.2) monoclonal antibody therapy-based combination approaches as first-line treatment for HER2-negative, CLDN18.2-positive gastric or GEJ cancer, and consider this information for current patient care.
• Review published and emerging research findings with novel HER2-targeted therapeutic approaches for HER2-positive gastroesophageal cancers, and assess their nonresearch role in patient care.
• Evaluate available treatment strategies for patients with gastric cancer and multiple biomarkers, such as HER2, PD-L1and CLDN18.2, and assess for optimal sequencing of available targeted therapies.
• Recall strategies commonly employed to mitigate and manage gastrointestinal side effects of CLDN18.2 monoclonal antibody-targeted therapy, and use this information to appropriately intervene when these side effects are suspected or diagnosed.

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

LEARNING OBJECTIVES

• Describe cereblon’s role in the degradation of key oncogenic proteins in order to better understand the rationale for the development of cereblon E3 ligase modulators (CELMoDs).
• Review the mechanism of action and unique characteristics of the CELMoDs under development for multiple myeloma (MM), and appreciate the similarities and differences between these therapies and currently approved immunomodulatory agents.
• Evaluate published efficacy and safety findings with CELMoDs in the advanced stages of development to prepare for the potential clinical availability of these agents for patients with relapsed/refractory MM.
• Assess various combination strategies under investigation with CELMoDs and other agents commonly administered to patients with MM, and recognize available and emerging research findings with various combination approaches.
• Appreciate the frequency and severity of various therapy-related adverse events encountered by patients undergoing treatment with CELMoDs, and use this knowledge to identify, manage and mitigate resultant side effects.
