Experimental Note Identified from the Human Clinical Data
In Vivo Model A retrospective survey in conducting clinical studies Homo sapiens
Experiment for
Molecule Alteration		 Directional sequencing assay; Direct sequencing assay
Experiment for
Drug Resistance		 Progression-free and post-progression survival asaay
Mechanism Description The identification of T790M as acquired resistance mechanism was clinically feasible. Although T790M had no prognostic or predictive role in the present study, further research is necessary to identify patients with T790M-mutant tumors who might benefit from newly developed T790M-specific TkIs.
