Increasing neutrophils in cancer microenvironment known as Tumor Associated Neutrophils (TANs), plays important rules in tumor progressivity, by releasing factors that modulate the extracellular matrix and inflammation of the tumor microenvironment of , such as neutrophil elastase (NE), neutrophil collagenase (MMP-8), and gelatinase B (MMP-9) (Shen et al., 2014). This evidence concerns the gene MMP9 and neoplasm.
