Evidence Type(s): Oncogenic, Predictive, Prognostic

Justification: Oncogenic: The presence of EGFR mutations, including L858R and G719C/S768I, is associated with oncogenic activity in NSCLC, as they are known to drive tumorigenesis. Predictive: The identified second-site EGFR mutations, such as T790M and C797S/G, are recognized as predictive markers for resistance to EGFR-TKIs, indicating their role in treatment response. Prognostic: The study reports that certain genetic alterations, including bypass pathway mutations and co-mutations of TP53 and RB1, are associated with significantly shorter progression-free survival (PFS) in patients treated with EGFR-TKIs, highlighting their prognostic significance.

Evidence Type(s): Diagnostic, Prognostic

Justification: Diagnostic: The passage mentions that patients with L858R mutations were included in a refined cohort, indicating that this variant is used to classify or define a specific group of patients with EGFR mutations in NSCLC. Prognostic: The passage discusses the progression-free survival (PFS) of patients with specific mutations, including L858R, suggesting that this variant correlates with disease outcome independent of therapy.

Evidence Type(s): Predictive, Oncogenic

Justification: Predictive: The passage discusses how the variants T790M, C797S/G, and L718V/Q are associated with resistance mechanisms to EGFR-TKIs, indicating their role in treatment response. Oncogenic: The variants mentioned are described as second-site mutations that contribute to resistance in the context of tumor development and progression in NSCLC.

Evidence Type(s): Diagnostic, Oncogenic

Justification: Diagnostic: The passage states that all 71 patients harbored baseline EGFR mutations, including specific variants, indicating their role in defining the patient cohort and confirming the presence of a disease subtype (NSCLC). Oncogenic: The mention of EGFR mutations, including G719C, L858R, and S768I, suggests that these somatic variants contribute to tumor development or progression in the context of non-small cell lung cancer (NSCLC).
