Assessment

Primary outcomes

Time to treatment failure of EGFR-TKIs between pretreatment EGFR T790M positive and negative groups detected by dd-PCR methods.

Key secondary outcomes

Time to treatment failure between different generations of EGFR-TKIs in patients with or without pretreatment EGFR T790M detected by dd-PCR.

Progression free survival of EGFR-TKIs between pretreatment EGFR T790M positive and negative groups by dd-PCR methods.

Examination of the appropriate cut-off value of EGFR T790M allele frequency for the efficacy of EGFR-TKIs.

T790M mutation detection ability after acquired resistance between Cobas and dd-PCR methods.

T790M mutation allele frequency by dd-PCR methods in pretreatment tumor tissue samples between T790M positive and negative groups by Cobas after acquired resistance.
