In the case of human non-small-cell lung cancer, no association has been shown between EGFR and Ki-67 [106] A correlation was observed between EGFR overexpression and a high Ki-67 labeling index, while the opposite was also observed, in that the absence of EGFR expression coincided with a low Ki-67 labeling index. This evidence concerns the gene MKI67 and non-small cell lung carcinoma.
