摘要:

目的 探讨基质金属蛋白酶-2(MMP-2)在口腔粘膜鳞状细胞癌中的表达特点及其与颈淋巴结转移的关系。方法 应用免疫组织化学LsAB法观察MMP-2在口腔癌生长前沿区与中央区细胞中的表达分布特点,并分别与颈淋巴结转移发生进行统计学分析。结果 71例口腔癌原发灶均有MMP-2表达,在口腔癌生长前沿区细胞的表达明显强于中央区(P<0·01),呈条带状分布;口腔癌前沿区细胞MMP-2表达强度与颈淋巴结转移的发生呈正相关(P<0·05),而中央区MMP-2表达强度与颈淋巴结转移无关(P>0·05)。结论 口腔癌生长前沿区细胞MMP-2 表达明显强于中央区,与颈淋巴结转移有关,可作为口腔癌颈淋巴结转移的预测指标。

Abstract:

Objective To explore the correlation between neck lymph node metastasis and matrix metalloproteinase-2 expres- sion at the invasive tumor front of oral squamous cell carcinomas(OSCC).Methods Immunohistochemistry LsAB technique was used to observe the expression of MMP-2 at the invasive tumor front and center of OSCC, and the correlation between the expres- sion ofMMP-2 in OSCC and neck lymph node metastasiswere respectively analyzed by statistics.Results The results demonstrat- ed thatMMP-2 existed in all 71 cases, which the expression ofMMP-2 at the OSCC frontwas more significant than that ofMMP-2 at the OSCC center (P<0.01), and related to neck lymph node metastasis (P<0.05).Conclusion The expression ofMMP- 2 at the OSCC front could be considered as an index of judging the present of neck lymph node metastasis of OSCC.
