MMP9 and neoplasm: Univariate Cox analysis revealed that the expressions of SCIN (HR = 2.727, 95% CI = 1.608–4.625, Concordance Index = 0.622, p < 0.001), MMP2 (HR = 2.156, 95% CI = 1.273–3.650, Concordance Index = 0.595, p = 0.004), MMP9 (HR = 2.467, 95% CI = 1.442–4.220, Concordance Index = 0.58, p = 0.001), the WHO grade, and tumor diameter were risk factors in our clinical samples (Table 2).
