目的

检测胃癌患者血管内皮因子C(VEGF-C)蛋白及mRNA在胃癌组织中的表达情况,探讨其与胃癌淋巴结微转移的关系。

方法

应用免疫组织化学法及RT-PCR法检测80例胃癌组织、癌旁组织及正常组织中的VEGF-C蛋白及mRNA表达情况;免疫组化法检测淋巴结微转移情况,比较有无淋巴结微转移的VEGF-C蛋白和mRNA的表达差异,明确存在的关联性。

结果

VEGF-C蛋白及mRNA两者在胃癌组织中明显高于癌旁组织和正常组织(P<0.05)。

结论

胃癌组织中的VEGF-C蛋白及mRNA与胃癌淋巴结微转移相关,基因检测优于蛋白,可作为评价胃癌患者是否存在淋巴结微转移的优选指标。

Objective

To explore the expression of vascular endothelial growth factor-C (VEGF-C) protein and mRNA in gastric cancer and its relationship with lymph node micrometastases.

Methods

Immunohistochemistry and RT PCR were used to detect the expression of VEGF-C protein and mRNA in gastric carcinoma tissue, adjacent tissue and normal tissue from 80 patients who suffered from gastric carcinoma. The expression level of VEGF-C protein and mRNA were compared between tissues with positive or negative lymph node micrometastases.

Results

The positive expression rates of VEGF-C protein and mRNA in gastric cancer tissue were significantly higher than those in adjacent tissue and normal tissue (P<0.05) , which had no relationship with the patients' age, sex, tumor size, location and distant metastasis. The expression of VEGF-C was positively correlated with lymph node metastasis (P<0.01) , and that of VEGF-C mRNA with micrometastasis was closer than that of protein.

Conclusions

VEGF-C protein and mRNA in gastric cancer tissue is correlated with lymph node micrometastases, and detection of VEGF-C mRNA is prior to detection of protein. VEGF-C mRNA can be serving as a more accurate indicator of lymph node micrometastases in the gastric cancer patients.
