Figure Lengend Snippet: Figure 2. (A) A scatterplot graph and correlation analysis (r = 0.837) results for VAF of the EGFR Ex.19 deletion or L858R mutations (X axis) and the EGFR T790M mutations (Y axis) (B) The cis–trans configuration between the activating and resistance mutations was analyzed by target RNA-Seq analysis of tissue biopsy specimens. This figure shows an example of a cis pattern of Ex.19 deletion and T790M visualized by the IGV genome browser. The region bridging Ex.19 and Ex.20 of EGFR was amplified by RT-PCR and the amplicon was sequenced by NGS. Most sequencing reads with a 15-bp Ex.19 deletion (represented by the blue line and number) harbor T790M mutations on the same RNA molecule. (C) Comparison of the VAF of EGFR T790M at point A between the no disappearance, A → B disappearance, and A → C disappearance groups. NS; no significance. (D) Kaplan–Meier plot of PFS for osimertinib treatment. Comparison of PFS between the no disappearance, A → B disappearance, and A → C disappearance groups (p = 0.442).
