胶质瘤是颅内肿瘤中最常见的恶性肿瘤之一,占颅内肿瘤的30%～50%,而恶性肿瘤侵袭性生长是一个多步骤的复杂过程。肿瘤经过缓慢的无血管生长期后,进入血管形成期,使瘤体得到营养而生长,因而血管生成是实体肿瘤生长和侵袭的前提。血管生成对肿瘤的生长和转移尤为重要。胶质瘤是一种富含血管的恶性肿瘤,血管的生成有利于肿瘤的生长、侵袭和转移。
Glioma is one of the most common malignant tumors in intracranial tumors, accounting for 30% to 50% of intracranial tumors. Invasive growth of malignant tumors is a complex multi-step process. Tumor after a slow period of non-vascular growth, into the formation of the blood vessels, the tumor to be nutrition and growth, and therefore angiogenesis is the premise of solid tumor growth and invasion. Angiogenesis is particularly important for tumor growth and metastasis. Glioma is a kind of malignant tumor rich in blood vessels. The formation of blood vessels is conducive to tumor growth, invasion and metastasis.
