      Evidence Type(s): Oncogenic

      Justification: Oncogenic: The passage indicates that the BRAF mutation V600E is classified as an oncogenic driver mutation, suggesting its role in tumor development or progression.

    11. OS of EGFR-TKI treated patients was similar for 1st and 2nd-line EGFR-TKI treatment. Patients not treated with EGFR-TKI had no benefit in OS. Re-biopsies obtained at progression revealed an EGFR-T790M mutation in 73% (n=

      Evidence Type(s): Predictive, Diagnostic

      Justification: Predictive: The passage indicates that patients with the EGFR-T790M mutation responded to the 3rd-generation EGFR-TKI osimertinib, suggesting a correlation between the variant and treatment response. Diagnostic: The EGFR-T790M mutation is mentioned as being revealed in re-biopsies at progression, indicating its role in defining or confirming the presence of a specific disease state in patients treated with EGFR-TKIs.
