      [Paper-level Aggregated] PMCID: PMC1240052

      Evidence Type(s): Predictive

      Summary: Mutation: G719S | Summary: The G719S mutation is associated with resistance to gefitinib, indicating its predictive value for therapy response in lung adenocarcinoma patients.

      Evidence Type: Predictive Mutation: L747_E749del A750P | Summary: The L747_E749del A750P mutation correlates with sensitivity to gefitinib and erlotinib, supporting its predictive role in therapy response for lung adenocarcinoma.

      Evidence Type: Predictive Mutation: L858R | Summary: The L858R mutation is linked to increased sensitivity to gefitinib and erlotinib, demonstrating its predictive significance for treatment outcomes in lung adenocarcinoma patients. Additionally, it is associated with a response to the irreversible EGFR inhibitor CL-387,785, which shows greater effectiveness compared to gefitinib or erlotinib in inhibiting colony formation and autophosphorylation.
