肿瘤血管在肿瘤形成、生长和转移过程中具有重要作用,它可为肿瘤细胞的快速增殖提供营养,由于肿瘤细胞代谢旺盛,需要的营养成分较正常细胞多,因而肿瘤组织往往包含更丰富的血管(参见图1)。一般说来,除了创伤愈合和妇女排卵期外,很少有血管形成过程出现,但是在肿瘤病理条件下血管生长调节失控是肿瘤恶性生长和转移的主要促进因素,因此选择肿瘤血管形成作为肿瘤治疗 Tumor blood vessels play an important role in the process of tumor formation, growth and metastasis. They provide nutrition for rapid proliferation of tumor cells. Since tumor cells are metabolically active and require more nutrients than normal cells, tumor tissues often contain more abundant blood vessels (See Figure 1). In general, there are few angiogenic processes other than wound healing and ovulation, but out of control of tumor growth under tumor pathology is a major contributor to the malignant growth and metastasis of the tumor, so tumor angiogenesis is selected as a tumor therapy
