Heydt C. et al. [74] compared 35 MET-amplified NSCLC samples (including 5 samples showing a low-level MET amplification, 10 samples with an intermediate-level MET amplification, and 10 samples with a high-level MET amplification), and found that MET-IHC had the best agreement with MET-FISH. This evidence concerns the gene MET and non-small cell lung carcinoma.
