2 FIGURE 1 Representative images of a c-MET- and phospho-MET-positive case of adenocarcinoma. A, Positive staining of c-MET with brown-stained membranes and cytoplasm (original magnification, ×200). B, Positive staining of phospho-MET with brown-stained membranes (original magnification, ×200).

3 FIGURE 2 Representative image of a bright-field in situ hybridization (BISH)-positive case of sarcomatoid carcinoma. Amplified MET gene signals appear as clusters of black dots and two to four CEN7 signals as red dots in the nuclei (original magnification, ×400).

4 FIGURE 3 Overall survival (OS) analysis. A, OS curves for patients with c-MET-negative (solid line) and c-MET-positive (dashed line) non-small cell lung carcinomas (NSCLCs) (p=0.189). B, OS curves for patients with c-MET-negative (solid line) and c-MET-positive (dashed line) nonsquamous NSCLCs (p=0.684). C, OS curves for patients with phospho-MET-negative (solid line) and phospho-MET-positive (dashed line) NSCLCs (p=0.547). D, OS curves for patients with phospho-MET-negative (solid line) and phospho-MET-positive (dashed line) nonsquamous NSCLCs (p=0.825). E, OS curves for patients with MET BISH-negative (solid line) and MET BISH-positive (dashed line) NSCLCs (p=0.135). F, OS curves for patients with MET BISH-negative (solid line) and MET BISH-positive (dashed line) nonsquamous NSCLCs (p=0.019).
