High cytoplasmic MET expression showed a significant negative prognostic effect only in patients with adenocarcinoma (p = 0.026), but not for the whole cohort (p = 0.411; Table 3 and Fig 3).MET gen copy count to chromosome 7 ratio>1 was a significant positive prognostic marker (p = 0.005). This evidence concerns the gene MET and adenocarcinoma.
