In the first part, PD Dr. med. Dr. rer. nat. Udo Siebolts first explains the mechanism of action of EGFR inhibitors as well as the results of clinical studies on EGFR inhibitors and then gives a brief overview of the recommendations for testing strategies and the testing algorithm.
In the second part, Prof. Dr. rer. nat. Sabine Merkelbach-Bruse discusses the molecular pathological diagnosis of EGFR exon 20 insertions, specifically the spectrum and frequency of EGFR exon 20 insertions in NSCLC, activation by EGFR exon 20 insertions, detection methods and the correct naming of EGFR exon 20 insertions. Afterwards, she summarized the proficiency testing results.
Furthermore, during the live discussion, further questions regarding the testing of EGFR exon 20 insertions in routine were discussed, which can be found at the end of the second part.
