摘要 为探讨癌基因c-myc、bcl-2蛋白产物在上颌窦癌中的表达及其临床意义,采用免疫组织化学方法,对46例上颌窦癌及56例正常鼻粘膜组织中癌基因c-myc、bcl-2蛋白产物进行了检测。结果表明,正常鼻粘膜鳞状上皮细胞中c-myc、bcl-2蛋白阳性率为0;上颌窦癌细胞中分别为73.9%(34/46),60.9%(28/46);复发组c-myc蛋白阳性率(91.7%,11/12),显著高于未复发组(67.7%,23/34),P<0.01;复发组bcl-2蛋白阳性率(50%,6/12),显著低于未复发组(64.7%,22/34),P<0.05。c-myc蛋白Ⅳ期阳性率显著高于Ⅱ期(P<0.05),bcl-2蛋白Ⅱ期阳性率显著高于Ⅳ期(P<0.05)。bcl-2癌蛋白的阳性率与原发癌病理分级成反比。结论:c-myc、bcl-2基因参与了上颌窦的癌变及发展过程,对判断病情及预测复发有一定意义。
