摘要 [目的]探讨乳腺癌及其切缘组织中hTERT、Syk表达及其与手术切缘的安全性关系。[方法]用SABC、SupervionTM二步免疫组化法分别检测40例乳腺癌标本及其周边上、下、内、外象限距癌肿1cm、2cm、3cm的切缘组织中hTERT、Syk表达。[结果]hTERT在乳腺癌组织中高表达,Syk在乳腺癌组织中低表达或不表达。免疫组化表明hTERT阳性表达在癌周3cm、2cm、1cm组织到癌组织之间呈现出逐渐增强的趋势(P<0.001);而Syk的阳性表达从癌周远端到癌中心逐渐减弱(P<0.001)。各象限相同距离的hTERT和Syk阳性表达率无统计学意义(P>0.05)。距肿块3cm处是Syk,hTERT的分子边界。[结论]距离肿块3cm可定为乳腺癌安全切除的分子边界。
