CE Information and Faculty Disclosures

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

    LEARNING OBJECTIVES

    • Develop an understanding of validated biomarkers of response in CRC, such as RAS mutations, microsatellite instability (MSI)/mismatch repair (MMR) deficiency, HER2 overexpression and BRAF V600E mutations, and consider the implications for molecular testing and clinical care.
    • Optimize the use of neoadjuvant and adjuvant systemic therapy for patients with localized CRC, considering various clinical and biological factors such as age, performance status, disease stage, MSI/MMR status and the potential relevance of molecular residual disease.
    • Formulate a plan to guide the selection and sequencing of therapy for patients with metastatic CRC (mCRC), accounting for tumor sidedness, biomarker profile, prior systemic therapy, symptomatology and personal goals of treatment.
    • Evaluate the biological rationale for the use of immune checkpoint inhibitors in the treatment of MSI-high/MMR-deficient localized or advanced CRC, and counsel patients regarding evidence-based and guideline-endorsed therapy recommendations.
    • Appreciate published and emerging research documenting the efficacy of BRAF/EGFR inhibition for newly diagnosed or relapsed/refractory mCRC with a BRAF V600E mutation, and optimally incorporate this therapeutic strategy into patient care.
    • Recognize available data with HER2-targeted therapies for HER2-positive mCRC, and consider the current role of FDA-approved approaches.
    • Apply available research to optimize the selection and sequencing of therapy for patients with mCRC and a KRAS G12C mutation, considering the implications of recent clinical trial findings and regulatory actions.
    • Recall ongoing trials evaluating novel biomarker-directed agents and strategies for CRC, and use this information to appropriately refer patients for study participation.
