MET and neoplasm: For the dPCR-negative and FISH-positive case, the dPCR assay reported a tumor fraction MET CN of 3.16, while the MET CN obtained from FISH was 5.53 with a MET/CCP7 ratio at 1.11 (less than 2), which is marginally above the cutoff of 5 and hence interpreted as marginally MET polysomy.
