‘Classical’ but not ‘other’ mutations of EGFR kinase domain are associated with clinical outcome in gefitinib-treated patients with non-small cell lung cancer

Evidence Type(s): Predictive, Oncogenic, Prognostic
Justification: Predictive: The text indicates that classical mutations in the EGFR tyrosine kinase domain are associated with sensitivity to tyrosine kinase inhibitors (TKIs) in patients with NSCLC, suggesting that these mutations can predict treatment response. Oncogenic: The presence of EGFR mutations, including E746V, G719D, and L858R, is implied to have a role in tumorigenesis, as they are described as somatic mutations found in tumor tissues, indicating their potential oncogenic nature. Prognostic: The text discusses median time to tumor progression (TTP) and overall survival (OS) in relation to different EGFR mutation statuses, suggesting that these mutations may have prognostic implications for patient outcomes.
