Evidence Type(s): Oncogenic, Predictive

Justification: Oncogenic: The L858R and T790M mutations in the EGFR gene are associated with altered sensitivity to erlotinib, indicating their role in promoting cancer cell proliferation and resistance to treatment. Predictive: The presence of the L858R and T790M mutations in NSCLC cell lines correlates with varying sensitivity to erlotinib, suggesting that these mutations can predict the response to this targeted therapy.

[Paragraph-level] PMCID: PMC4385014 Section: RESULTS PassageIndex: 3

Evidence Type(s): Predictive, Oncogenic

Justification: Predictive: The passage discusses the sensitivity of different cell lines to erlotinib treatment, indicating that the presence of the L858R and T790M mutations correlates with reduced sensitivity to the drug, which is a predictive relationship regarding therapy response. Oncogenic: The L858R and T790M mutations are described in the context of their presence in NSCLC cell lines, suggesting their role in tumor development or progression, which aligns with the definition of oncogenic variants.

Evidence Type(s): Predictive, Oncogenic

Justification: Predictive: The passage discusses the sensitivity of NSCLC cell lines with specific EGFR mutations (L858R and T790M) to the anti-proliferative effect of erlotinib, indicating a correlation with treatment response. Oncogenic: The presence of the L858R and T790M mutations in the cell lines suggests that these somatic variants contribute to tumor development or progression, as they are associated with specific cancer cell lines.
