EEB: EGFR Exon 20 Insertions: Recent Findings, Laboratory Considerations, and Clinical Implications
EGFR Exon 20 Insertions
This webinar is a recorded presentation of a live broadcast and includes a pre-test, the presentation, audience Q&A, handout, and a post-test. Continuing Education is available for the webinar.
The epidermal growth factor receptor (EGFR) gene encodes a receptor tyrosine kinase. In NSCLC numerous hotspot mutations within the tyrosine kinase domain led to constitutive activation and oncogenesis. Unlike classical TKI sensitive mutations, exon 20 insertions (which account for ~5% of total) are resistant to 1st, 2nd and 3rd generation EGFR TKIs. However, newly approved targeted therapies options have recently become available and been shown to be effective therapeutic options when this variant type is present. The scientific background information, testing techniques, and clinical applications of this biomarker will be discussed.
- Describe the molecular biology of EGFR exon 20 mutations.
- Identify technical challenges for the detection of EGFR exon 20 mutations.
- Explain the clinical relevance of EGFR exon 20 mutations.

This activity has been planned and implemented in accordance with the Essential Areas and policies of the Accreditation Council for Continuing Medical Education through the joint providership of American Society for Clinical Pathology (ASCP) and Association for Molecular Pathology (AMP). The American Society for Clinical Pathology (ASCP) is accredited by the ACCME to provide continuing medical education for physicians.
The ASCP designates this enduring material for a maximum of 1.0 AMA PRA Category 1 Credit(s)™. Physicians should claim only credit commensurate with the extent of their participation in the activity.
This continuing medical laboratory education activity is recognized by the American Society for Clinical Pathology for 1.0 hours of CMLE credit. ASCP CMLE credit hours are acceptable for the ASCP Board of Certification (BOC) Certification Maintenance Program (CMP). CMLE credit hours meet the continuing education requirements for the ASCP Board of Certification Credential Maintenance Program (CMP) and state relicensure requirements for laboratory personnel. Participants should claim only the credit commensurate with the extent of their participation in the activity.
