摘要: 目的 探讨基质金属蛋白酶-9(matrix metalloproteinase9,MMP-9)和血管内皮生长因子(vascular endothelial growth factor,VEGF)在造釉细胞型颅咽管瘤中的表达及其与肿瘤侵袭、复发的相关性。方法 应用免疫组化法对40例造釉细胞型颅咽管瘤标本(原发组24例,复发组16例)中MMP-9和VEGF的表达进行检测。结果 MMP-9在复发组造釉细胞型颅咽管瘤中的总阳性表达率93.7%,明显高于原发组总阳性率41.7%(P<0.05);VEGF在复发组造釉细胞型颅咽管瘤中的总阳性表达率87.5%,明显高于原发组总阳性率45.8%(P<0.05)。复发组釉质型颅咽管瘤中MMP-9与VEGF表达呈正相关(P<0.05),原发组造釉细胞型颅咽管瘤中MMP-9与VEGF表达无明显相关性。结论 MMP-9和VEGF可能在造釉细胞型颅咽管瘤侵袭生长和肿瘤复发过程中扮演着重要的角色,并可能存在协同作用。MMP-9和VEGF可能成为评价造釉细胞型颅咽管瘤侵袭性生长和复发倾向的重要参考指标。

Abstract: Objective To explore the expression of matrix metalloproteinase 9(MMP-9) and vascular endothelial growth factor(VEGF) in adamantinomatous craniopharyngiomas and the correlation between the expression of MMP-9,VEGF and the invasion/recurrence of tumor.Methods Expressions of MMP-9 and VEGF were tested by immunohistochemistry(IHC) in 40 cases of adamantimous craniopharyngioma,including 24 cases of primary group and 16 cases of secondary group.Results The total expression rates of MMP-9 in secondary group were significantly higher than that of primary group(93.7% vs 41.7%,P<0.05),and the total expression rates of VEGF in secondary group were significantly higher than the primary group(87.5% vs 45.8%,P<0.05).There were mutually positive correlations between MMP-9 and VEGF expressions in secondary group of adamantinomatous craniopharyngioma.Conclusion MMP-9 and VEGF may play an important role in the invasive growth and recurrence of adamantimous craniopharyngioma,and positive-feedback regulate each other.MMP-9 and VEGF may become potential biomarkers to evaluate the inclination of invasion and recurrence in adamantimous craniopharyngioma.
