摘要 目的检测喉鳞癌中脆性组氨酸三联体基因(FHIT)、增殖细胞核抗原(PCNA)和Ki67增殖蛋白(Ki67)的表达特征,探讨FHIT对增殖的作用。方法 67例喉鳞癌患者的临床资料和术后蜡块组织作为观察组,喉黏膜不典型增生的术后组织53例作为对照组,收集上述距肿物边缘>2 cm非肿瘤性喉黏膜组织53例作为正常对照组。应用免疫组化二步法检测三组FHIT、PCNA和Ki67的表达。结果三组FHIT、PCNA和Ki67的阳性率差别显著(P<0.000 1)。观察组中FHIT、PCNA和Ki67的阳性率均与肿瘤最大径、分化程度、是否伴有脉管内瘤栓相关。PCNA和Ki67的表达与淋巴结转移相关。线性相关分析显示观察组中FHIT和PCNA、FHIT和Ki67的表达均具有负相关性。结论喉鳞癌术后组织中FHIT低表达,PCNA和Ki67高表达对促进肿瘤形成和进展有一定作用,FHIT在调节肿瘤性进展过程中可能与对肿瘤细胞增殖的调节有关。
