Number of participants that the trial has enrolled 248
Results No concurrent C797S mutation with known EGFR gene mutation was identified. T790M mutation was identified in 12 patients (4.9%). ERBB2 or MET gene amplification was found in a few patients (0.0-0.4%). MDM2 gene amplification was associated with tumor recurrence and shorter progression free survival for first or second generation EGFR-TKIs.

Baseline Characteristics Consecutive patients who underwent initial lung resection or surgical tumor biopsy in Fukushima Medical University Hospital between January 2007 and December 2015, and were diagnosed with NSCLC harboring a known EGFR gene activating mutation (e.g., exon 19 deletion, L858R, T790M, S768I, G719X and L861Q) at the time samples were collected.
Participant flow All cases satisfying the above were incorporated with written consent.
Adverse events Not applicable
Outcome measures Clinicopathological parameters, presence of EGFR C797S and T790M mutations. and gene amplifications(ERBB2, MET, EGFR, ALK, BRAF, FGFR1, MYC, RET, CCND1, CCND2, CDK4, CDK6, MDM2 and MDM4)

Other
Other related information To clarify the frequency of EGFR C797S mutation in EGFR-TKI naive NSCLC surgical specimen using an improved PNA-LNA PCR clamp method, and allelic pattern analysis of T790M and C797S mutation is performed(Sanger's method). Sensitivity and resistance against EGFR-TKI was analyzed through comparison between EGFR T790M mutation(PNA-LNA clamp method), HER2 amplification, and MET amplification (quantitive PCR method) and clinicopathological features.
