Non-small cell lung cancer (NSCLC) accounts for approximately 85% of all lung cancers. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are currently viewed as the established first-line therapy for patients with advanced NSCLC with EGFR mutations.</p><p><strong>Summary: </strong>The potential predictive value of the quantitative abundance of epidermal growth factor receptor (EGFR) mutations in the treatment of NSCLC is widely recognized and regarded as a significant indicator. The definition of mutation abundance in the EGFR gene in most current studies is mainly calculated based on the ratio of mutation to wild-type gene copy number or based on the ratio of allele number; for example, variant allele frequency is the ratio of the number of mutant alleles to the total number of alleles at a particular locus. Results of the included primary studies are as follows. (1) Significant association between EGFR mutation abundance and progression-free survival (PFS): median PFS was significantly longer in the high abundance group (11.0 months, 95% CI: 9.7-12.3 months) than in the low abundance group (5.3 months, 95% CI: 3.6-7.0 months) in the study by Liu et al. High mutation abundance (HR: 0.77, 95% CI: 0.66-0.82, p = 0.037) was an independent prognostic determinant of PFS in the study by Wang et al. Among patients receiving EGFR-TKI as first-line therapy, the median PFS was significantly longer in the high mutation abundance group than in the low mutation abundance group (12.7 months vs. 8.7 months, p = 0.002). EGFR mutation abundance ≥30% was an independent risk factor for PFS (HR: 1.64, 95% CI: 1.17-2.31). (2) Significant association between EGFR mutation abundance and overall survival (OS): the median OS in the high abundance group in the study by Liu et al. was 20.9 months (95% CI: 18.3-23.5 months), while that in the low abundance group was 13.0 months (95% CI: 10.0 months) (95% CI: 10.3-15.7 months); longer OS was independently associated with high mutation abundance (HR: 0.62, 95% CI: 0.50-0.79, p = 0.027).</p><p><strong>Key messages: </strong>The objective of this article was to conduct a comprehensive examination and analysis of the association between the abundance of EGFR mutations in NSCLC and the effectiveness of treatment with TKIs while also considering the development of drug resistance.</p>","PeriodicalId":19543,"journal":{"name":"Oncology Research and Treatment","volume":null,"pages":null},"PeriodicalIF":2.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142366067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SPSS version 26.0 statistical software was used for statistical analysis. P &lt; 0.05 was determined to be statistically significant.RESULTS105 patients were included.

Upon disease progression, detection of MET gene amplification prompted the addition of a selective MET inhibitor to the existing EGFR-TKI regimen, resulting in a complete response for the patient.DISCUSSION/CONCLUSIONThe molecular heterogeneity of this condition has significantly increased in complexity over recent years, marked by the identification of baseline co-alterations and development of a broad spectrum of resistance mechanisms post-EGFR tyrosine kinase inhibitor (TKI) therapy. This complexity poses a substantial challenge to clinicians. Despite the rapid advancement of targeted therapies and the implementation of treatment escalation through combination strategies, there remains an ongoing debate regarding which patients would benefit most from combination therapies, both in the initial treatment phase and in the setting of disease progression, particularly when off-target resistance mechanisms or co-alterations are identified.","PeriodicalId":19543,"journal":{"name":"Oncology Research and Treatment","volume":null,"pages":null},"PeriodicalIF":2.4,"publicationDate":"2024-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265367","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
