Abstract:

目的:探讨两种新辅助化疗(NACT)对宫颈癌微淋巴管密度和血管内皮生长因子表达的影响及疗效。方法:选择60例Ⅰb2-Ⅱb期宫颈鳞癌患者随机分为两组,分别行全身静脉化疗和髂内动脉栓塞灌注化疗,通过免疫组织化学法和实时定量PCR法,检测两种途径NACT前后的局部宫颈癌组织微淋巴管密度(LMVD)和血管内皮生长因子-A,C,D(VEGF-A,C,D)的表达量,并分析两种NACT疗效与临床病理因素的关系。结果:1VEGFA,C,D在癌症组织表达量明显高于正常组织。2经静脉化疗后,宫颈癌组织中VEGF-D治疗后的表达量低于治疗前(P<0.05),VEGF-A,C在治疗前后的表达量无明显变化;经动脉灌注化疗后,宫颈癌组织中VEGF-C,D治疗后的表达量明显低于治疗前(P<0.05),VEGF-A的表达量在治疗后也有所下降,但无统计学意义(P>0.05)。3静脉化疗和动脉灌注化疗均降低了宫颈癌组织内的LMVD,动脉灌注化疗降低程度更显著(P<0.05)。4两组患者均达到明显的近期临床缓解,动脉灌注化疗组患者的疗效优于静脉组,两组患者的总有效率有明显差异,且有统计学差异(P<0.05)。5静脉化疗疗效与肿瘤淋巴结转移及肿瘤直径有关,与临床分期、组织分化均无关;动脉灌注化疗总的有效率高达93%,但其疗效与临床分期、组织分化、淋巴结转移及肿瘤大小均无明显关系。结论:动脉灌注栓塞化疗在宫颈癌近期治疗效果好,可以有效抑制肿瘤淋巴管生成及血管内皮生长因子的表达
