恶性肿瘤细胞对机体的致病性源于其自主性生长、浸润转移、分泌细胞因子及逃避机体的免疫攻击等特性。在浸润转移过程中,微脉管系统的作用不容忽视,现已证实淋巴管是肿瘤细胞转移播散至局部淋巴结的主要通路。对肿瘤微血管的研究已比较深入,抗肿瘤血管生成治疗也应运而生,而对 Pathogenicity of malignant tumor cells to the body stems from its own growth, invasion and metastasis, secretion of cytokines and escape the body’s immune attack and other characteristics. In the invasion and metastasis process, the role of the microvasculature can not be ignored, it has been confirmed that lymphatic metastasis of tumor cells to local lymph node dissemination of the main pathway. The study of tumor microvascular has been more in-depth, anti-tumor angiogenesis has also emerged, and
