1、C和VEGF-D在乳腺癌中的表达及其作用肿瘤2006年6月第26卷第6期TumorVo1.26,No.6,Jun.2006?551?VEGF-C和VEGF-D在乳腺癌中的表达及其作用ClinicalResearch?临床研究汤红平,张雅洁,顾莹莹,张惠球(1,广州医学院病理教研室,广州510182;2,广州医学院第一附属医院病理科,广州510120)[摘要]目的:探讨VEGF—C,VEGF—D在乳腺癌组织ee的表达及其作用.方法:采用免凝组织化学方法对l12倒乳腺癌组织切片染色,观察乳腺癌组织中VEGF—C,VEGF-D以及IYVE一1的表达情况.结果:儿2倒乳腺癌
2、组织ee,VEGF—C阳性率为83.0,VEGF—D阳性率为75,9.二者表达呈正相关(r一0,767,P<0,001).VEGF-C阳性指数在淋巴结转移组(6O.54-+-16,73)明显高于未转移组(43.56-+-15.64)(P%0.05).VEGF—D阳性指数在淋巴结转移组(6O,42±16,26)明显高于末转移组(41.82±15.93)(P%0,05).随着癌细胞VEGF—C和VEGF—D表达强度增强,IYVE一1阳性淋巴管数也随之增加,各组间均有显着性差异(P%0,001).VEGF—C和VEGF—D的表达与IYVE一1阳性淋巴管均呈一定相关性
3、,(前者r一0,864,P%0,001;后者r:0,870,Pd0,001).乳腺癌中IYVE-1阳性淋巴管数在淋巴结转移组(13,72±7,74)明显高于未转移组(7.69±5,85).结论:VEGF—C及VEGF—D在人乳腺癌组织呈高水平表达,表达强度与肿瘤间质淋巴管密度及肿瘤淋巴结转移有关;肿瘤间质淋巴管密度与肿瘤淋巴结转移密切相关.[关键词]乳腺肿瘤;血管内皮生长因子C;血管内皮生长因子D;血管内皮生长因子受体一3;内皮,淋巴管[中图分类号]R737,9[文献标识码]A[文章编号]1000—7431(2006)06—055卜04Expressionsofva
