China 【Abstract】 Objective To investigate the expression of matrix metalloproteinase-7 (MMP-7) in glioblastoma tissues and its relationship with postoperative survival. Methods　The expressions of MMP-7 in 60 cases of glioblastoma tissues were detected by using the two-step immunohistochemical staining method. The relationship between MMP-7 expression and postoperative survival was analyzed by statistical method. Results　The total rate of MMP-7 expression in glioblastoma patients was 73.3%. The postoperative survival in strong expression group was significantly shorter than that in weak expression group (χ2=7.043, P=0.008). Conclusion　The expression of MMP-7 might be an important prognostic factor associated postoperative survival in glioblastoma patients. 【Key words】　Glioblastoma; Immunohistochemistry; Matrix metalloproteinase-7 胶质母细胞瘤是星形细胞肿瘤中恶性程度最高 层粘连蛋白等多种细胞外基质，与多种恶性肿
