摘要 目的研究Ki67,VEGR及EGFR的表达与鼻咽癌(NPC)临床分期、分化程度之间的关系。方法应用免疫组化分析32例NPC Ki67、VEGF及EGFR的表达。结果(1)Ki67、VEGF及EGFR在32例NPC中的阳性表达率分别为84.4%(27/32),84.4%(27/32),78.1%(25/32)。(2)晚期(Ⅲ,Ⅳ期)鼻咽癌患者Ki67、VEGF及EGFR阳性表达率分别为100%(20/20)、100%(20/20)及95%(19/20)均明显高于早期(Ⅰ,Ⅱ期)患者的表达率,分别为58.3%(7/12)、58.3%(7/12)及50%(6/12),差异均有显著性(P<0.05);有颈部淋巴转移患者的Ki67、VEGF及EGFR阳性表达率分别为96.1%(25/26)、92.3%(24/26)及88.5%(23/26),均明显高于无颈部淋巴转移患者的表达率,分别为33.3%(2/6)、50%(3/6)及33.3%(2/6),差异均有显著性(P<0.05);未分化癌Ki67、VEGF及EGFR阳性表达率分别为100%(10/10)、90%(9/10)及80%(8/10),均高于低分化癌患者的表达率77.2%(17/22)、81.8%(18/22)、77.3%(17/22),但差异均无显著性(P>0.05)。结论(1)鼻咽癌中存在着Ki67、VEGF及EGFR的高表达;(2)Ki67、VEGF及EGFR均与鼻咽癌的临床分期及有无颈部淋巴转移有相关性,均与病理分化程度无相关性。
