  • However, careful analysis of the exon 20 sequence chromatograms in both forward and reverse directions from this patient's lung biopsy specimen obtained after disease progression on gefitinib demonstrated an additional small peak at nucleotide 2369, suggesting a C→T mutation (Figure 2A, upper panels; Table 1).

  • However, analysis of DNA from cells in the pleural effusion that developed after treatment with gefitinib showed the C→T mutation at nucleotide 2369 in exon 20 (Figure 2C, lower panels; Table 1), corresponding to the T790M mutation described above.

  • These observations provide convincing evidence that, at least in some patients with NSCLC, resistance to gefitinib or erlotinib can be attributed to acquisition of a T790M mutation in the context of EGFR.

  • Because of metastatic involvement of multiple mediastinal lymph nodes and clinical features known at that time to be predictive of response to gefitinib (female, never smoker, bronchioloalveolar variant histology), she was placed on “adjuvant” gefitinib 1 mo later (Figure S1C, left panel).

  • The mechanism of resistance in three patients was acquisition of a T790M substitution in EGFR that was not present at time of diagnosis, but was detected with progression of disease after initial response to gefitinib or erlotinib.
