Abstract:
Objective To analyze the expression levels of matrix metallo proteinase-2 (MMP-2) and matrix metallo proteinase-9 (MMP-9) in serum of patients with esophageal cancer,and to analyze the interrelations among MMP-2,MMP-9 and clinicopathologic characteristics of esophageal cancer.Methods The levels of serum MMP-2,MMP-9 from 60 patients with esophageal cancer were detected by enzyme linked immunosorbent assay.The interrelations among MMP-2,MMP-9 and clinicopathologic characteristics of esophageal cancer including age,gender,histological type,whether or not lymph nodes metastasis and TNM staging were analyzed.Results The levels of MMP-2 and MMP-9 in control group were 61.31 ng/ml and 87.67 ng/ml,the levels of MMP-2 and MMP-9 in patients with esophageal cancer were 121.66 ng/ml and 169.73 ng/ml.The levels of MMP-2 and MMP-9 were significantly higher in patients with esophageal cancer than that of general population (t =3.015,P =0.007; t =2.037,P =0.04).The level of MMP-2 was significantly associated with whether or not lymph node metastasis (t =2.150,P =0.04) and clinical staging (t =2.186,P=0.03).The level of MMP-9 was significantly associated with whether or not lymph node metastasis (t =2.390,P =0.02) and clinical staging (t =2.149,P =0.03).The levels of MMP-2 and MMP-9 have no reference to age,gender and histological type (all P＞0.05).Conclusion MMP-2 and MMP-9 may correlate with tumor invasion and metastasis in patients with esophageal cancer.
