摘要:

目的 研究血管内皮生长因子-C(VEGF-C)对鳞癌细胞淋巴道转移能力的影响 ,以探讨其在口腔黏膜鳞癌淋巴道转移机制中的作用。方法 用本课题组前期建立的 VEGF-C高表达舌癌细胞株 ,以裸小鼠皮下接种构建动物肿瘤模型 ,观察VEGF-C高表达对移植瘤的生长和颈淋巴转移的影响。结果 VEGF-C高表达移植瘤实验组的颈淋巴结转移率高于对照 组 ,但实验组与对照组的移植瘤原发灶生长速度没有明显差异。结论 VEGF-C对舌鳞癌的淋巴道转移有相对特异的作用 ,可作为口腔癌颈淋巴转移预防和治疗的新靶位

Abstract:

Objective To study the role that vascular endothelial growth factorC plays in the lymph node metastasis of the squamous cell carcinoma (SCC) of tongue.Methods An established VEGFC transfected Tca8113 cell strain (VcTca) was heterotransplanted into BALB/C nude mice subcutaneously. The expression of VEGFC and VEGFR3 was detected. The property of tumorigenesis and metastasis of the transfected cell was investigated.Results Jugular lymphatic metastases developed in 4/6 mice of VcTca group in 6 weeks after transplantation, while no lymph node metastasis was found in mice with tumors of nontransfected Tca8113 cell (Tca) and mock transfected cell(pDTca) at the same time. There was no difference in tumor weight among VcTca, pDTca and Tca (P>0 05).Conclusion\ It is suggested that VEGFC could promote lymph node metastatic ability of Tca8113 cell, and could be utilized as a target of new regimen in prevention and treatment for lymphatic metastasis of oral carcinomas.
