两篇研究报告的结果为脑肿瘤的治疗提供了新的希望 :第一项研究表明 ,树突状细胞疫苗联合化疗比单独使用任一疗法都可以延长病人的存活时间 ;另一项研究提示 ,类大麻素在脑肿瘤中可以通过降低血管内皮生长因子 (VEGF)水平而发挥血管生成抑制剂的作用。两项研究工作都与治疗多形 The results of the two studies provide new hope for the treatment of brain tumors: the first study showed that dendritic cell vaccine combined with chemotherapy can prolong the survival time of patients compared with either therapy alone; another study suggests that, Cannabinoids play a role as angiogenesis inhibitors in brain tumors by decreasing the level of vascular endothelial growth factor (VEGF). Both studies are polymorphic with treatment
