From: MMP-9 expression varies according to molecular subtypes of breast cancer
Overexpression of MMP-9 is associated with a higher incidence of metastases. Increased expression of MMP-9 is associated with higher incidence of metastasis. Only lymph node, lymphovascular invasion and lung metastases reached the level of statistical significance when compared to patients with low MMP-9 expression. Chi-square test was realized with Yates’ continuity correction and a two-sided Fisher exact test were performed to analyze metastases.
