Of the 7908 patients tested for EGFR mutations at initial diagnosis, one or more mutations were reported in 11.7% of all cases (95% CI, 11.0-12.4%; n = 925) (Table 2). Female patients were more likely to harbor EGFR muta
[Paragraph-level] PMCID: PMC8307492 Section: RESULTS PassageIndex: 9
Evidence Type(s): Diagnostic, Oncogenic
Justification: Diagnostic: The passage discusses the prevalence of EGFR mutations, including L858R and L861X, in patients at initial diagnosis, indicating their association with the disease and their use in defining the mutation status of patients. Oncogenic: The variants L858R and L861X are described as actionable mutations within the context of EGFR, suggesting their role in tumor development or progression.
