Pulmonary adenocarcinoma: EGFR exon 19 insertion – report of 3 cases (ECP 2024)
The sequenced adenocarcinomas presented predominant acinar pattern as well as solid, papillary/micropapillary and lepidic patterns, respectively, without relevance for the mutational status. Multiple parallel sequencing (MPS) allows accumulation of tumoural mutational knowledge overtaking concise standardized mutational equipment. Considering effective lab costs, clinical decisions for therapeutic available options and MPS is now the more advisable method.

Efficacy of EGFR-Tyrosine Kinase Inhibitors in Patients with NSCLC Harboring EGFR Exon 19 Insertions: A Report from the LC-SCRUM-Asia (IASLC-WCLC 2024)
We also studied preclinical Ba/F3 models expressing EGFR -K745_E746insIPVAIK (Ba/F3-IPVAIK) and EGFR -delE746_A750 (Ba/F3-Del19) to investigate the sensitivity to 1st-generation (gen) (gefitinib and erlotinib), 2nd-gen (afatinib, dacomitinib, and poziotinib), 3rd-gen (osimertinib), and EGFR exon 20 insertion active TKIs (mobocertinib, sunvozertinib, and zipalertinib). The preclinical therapeutic window of Ba/F3-IPVAIK and Ba/F3-Del19 for all the 2nd generation TKIs were similarly favorable, whereas Ba/F3-IPVAIK had much unfavorable therapeutic windows to other EGFR-TKIs compared to Ba/F3-Del19. Conclusions : Our clinical and preclinical findings indicate 2nd-gen EGFR-TKIs are more effective than 1st and 3rd-gen EGFR-TKIs in patients with EGFR exon 19 insertions.

Molecular Characteristics and Response to TKIs in NSCLC Patients with EGFR Exon 19 Insertions (IASLC-WCLC 2023)
Results from in vitro experiments suggested that the EGFR I740_K745dup mutation might be more sensitive to afatinib. Our comprehensive analysis of EGFR 19ins in lung cancer patients revealed genomic characteristics and clinical response that are distinct from 19del/delins. Our findings help better inform clinical action and might facilitate the development of more precise therapeutic options for patients with these uncommon driver mutations.

EGFR exon 19 insertion EGFR-K745_E746insIPVAIK and others with rare XPVAIK amino-acid insertions: Preclinical and clinical characterization of the favorable therapeutic window to all classes of approved EGFR kinase inhibitors. (PubMed, Lung Cancer)
This is the largest preclinical/clinical report to highlight that EGFR-K745_E746insIPVAIK and other mutations with exon 19 XPVAIK amino-acid insertions are rare but sensitive to clinically available 1st, 2nd, and 3rd generation as well as EGFR exon 20 active TKIs; in a pattern that mostly resembles the outcomes of models with EGFR-L861Q and EGFR-A763_Y764insFQEA mutations. These data may help with the off-label selection of EGFR TKIs and clinical expectations of outcomes when targeted therapy is deployed for these EGFR mutated lung cancers.

Uncommon single and compound EGFR mutations: clinical outcomes of a heterogeneous subgroup of NSCLC. (PubMed, Curr Probl Cancer)
For mutations in exon 18 (not in codon 719) and exon 20 insertions, chemotherapy seems the most effective available option. The addition of immunotherapy to chemotherapy could change this approach in the next future.
