Fig. 5From: Whole-exome sequencing explored mechanism of selpercatinib resistance in RET-rearranged lung adenocarcinoma transformation into small-cell lung cancer: a case reportCopy number variations at initial diagnosis and after transformation. The X-axis was the sequence of Chromosomes, the Y-axis was the fold change of variation, and the arrows indicated the locations of Chromosomes with large copy number variation at initial diagnosis and after transformation into SCLCBack to article page
