Similarly, establishing ratios between serum Ki-67 concentrations and neutrophil, lymphocyte, and monocyte counts as indicators of inflammation, as well as components of the tumour microenvironment, was unable to distinguish mammary adenocarcinomas from adenomas (p = 0.83, p = 0.50 and p = 0.45, respectively; Table 5). This evidence concerns the gene MKI67 and neoplasm.
