Change of tumo r volume and tumor growth inhibiting rate,blood perfusion of tumor,expression of VEGF mRNA in tumor tissue,serum VEGF level,SSTR1-5 mRNA expression and tumor c ells apoptosis were evaluated.

• 观察肿瘤生长抑制率、检测肿瘤组织血供、瘤组织VEGFmRNA表达水平、血清VEGF水平、肿瘤组织中生长抑素受体(somatostatinreceptor,SSTR) 1- 5mRNA表达水平并检测肿瘤组织细胞凋亡水平。
