ABSTRACT
<p><b>OBJECTIVE</b>To study the expression of Notch1, MMP-2 and MMP-9 in glioma patients and their relationship with progression and prognosis of gliomas.</p><p><b>METHODS</b>Sixty-four cases of glioma were included in this study. There were four cases of grade 1 tumor, twenty-five cases of grade 2, nine cases of grade 3, and twenty-six cases of grade 4. Immunohistochemistry (SP staining method) was used to detect the expression of Notch1, MMP-2 and MMP-9 in glioma tissues and adjacent non-tumor tissues, and the patients were followed up.</p><p><b>RESULTS</b>Notch1, MMP-2 and MMP-9 were detected in glioma tissues but not in adjacent non-tumor tissues. The expression of Notch1 was increased with the pathological grade of the gliomas (r = 0.262, P < 0.05). The survival time of patients with strong expression of Notch1 was 31.0 months, significantly shorter than that of patients with non-strong positive (negative, weak and moderately) Notch1 expression (53.0 months, P < 0.05). Significant difference in survival time was observed between patients with negative and positive expression of MMP-9 (P < 0.05).</p><p><b>CONCLUSIONS</b>Notch1, MMP-2 and MMP-9 are closely correlated with the progression and prognosis of malignant gliomas. Notch1 may participate in the expression regulation of MMP-2 and MMP-9. Compared with MMP-2, MMP-9 may play a more important role in determining the prognosis of malignant glioma. Notch1 and MMP-9 may become new biological markers for prognosis of patients with malignant glioma.</p>
