索拉非尼和沙利度胺对肝癌患者血清中VEGF-C、VEGF-D及微血管密度的影响

目的:探讨索拉非尼和沙利度胺这两种不同的化疗药物,对肝癌患者血清中VEGF-C、VEGF-D及微血管密度的影响。方法:将患者分成3组,每组16例。对照组采用常规治疗并服用安慰剂;索拉非尼和沙利度胺这两个组患者中,前者服用索拉非尼400 mg/次,2次/d,治疗6个月;后者服用沙利度胺每日服200mg,每周增加200mg/d,直至最大剂量每日600mg,至少服用4月。ELISA检测患者血清中VEGF-C、VEGF-D;免疫组织化学检测肝癌组织中微血管密度。结果:对照组患者血清中VEGF-C的水平为210ng/ml,索拉非尼组患者血清中VEGF-C的水平为132ng/ml,而沙利度胺组患者血清中VEGF-C的水平为186ng/ml。与对照组相比,索拉非尼组和沙利度胺组患者血清中VEGF-C的水平均降低。对照组患者血清中VEGF-D的水平为322ng/m1,索拉非尼组患者血清中VEGF-D的水平为217ng/ml,而沙利度胺组患者血清中VEGF-D的水平为256ng/ml。与对照组相比,索拉非尼组和沙利度胺组患者血清中VEGF-D的水平均降低。索拉非尼组患者血清中VEGF-D的水平明显低于沙利度胺高(P<0.05)。对照组肝癌组织MVD为(44.32±5.16)个,索拉非尼组患者肝癌组织MVD为(21.75±1.49)个,而沙利度胺组患者肝癌组织MVD为(34.78±2.31)个。结论:多靶点化疗药物索拉非尼对肝癌患者血清中VEGF-C、VEGF-D及微血管密度的影响最大,深入探讨其作用机制,可为其肝癌患者提供新的化疗方案。

Effect of Sorafenib and Thalidomide on the VEGF-C, VEGF-D and Microvessel Density of Patients with Liver Cancer

Objective:To discover the effect of Sorafenib and thalidomide on the VEGF-C,VEGF-D and microvessel density of patients with liver cancer.Methods:The patients were divided into 3 groups of 16 cases.Control group were treated with conventional method and placebo;The other two groups took sorafenib and thalidomide.The former group took sorafenib 400 mg/time,twice/d for 6 months;the latter took thalidomide 200mg/day,increased 200mg/d every week,up to the maximum daily dosage of 600mg which lasted at least four ...
