FIGURE 1 Computed tomography scans showed metastatic liver metastases (A) before and (B) approximately 5 months after the administration of ceritinib. C and D, Computed tomography and positron emission tomography/computed tomography indicated exacerbation of the hepatic metastases. Scale bar: 1 cm.

FIGURE 2 Direct sequencing with capillary electrophoresis of biopsy samples obtained from the liver metastases (A) before and (B) after the administration of ceritinib using an ABI PRISM 310 Genetic analyzer. C, Computed tomography scans performed 6 weeks after the administration of alectinib showing the rapid response of the hepatic metastases to alectinib. Scale bar: 1 cm.
