  • 摘要: 目的研究胆囊腺癌、癌旁组织和慢性胆囊炎组织中的α-甲酰基辅酶A消旋酶(P504S)和P63蛋白表达及其临床意义。方法108例胆囊腺癌、46例癌旁组织和35例慢性胆囊炎手术切除标本常规制作石蜡包埋切片,P504S和P36染色方法为EnVisionTM免疫组化法。结果胆囊腺癌P504S和P63阳性率(51.9%,43.5%)及其评分(2.13±1.88,1.98±1.73)明显高于癌旁组织阳性率(17.9%,10.9%)及其评分(0.72±1.24,0.61±1.39)和慢性胆囊炎阳性率(14.3%,6.0%)及其评分(0.59±1.34,0.32±1.22)(P<0.01);腺瘤癌变或高分化腺癌、无淋巴结转移及未侵犯周围组织器官病例P504S表达阳性率及其评分明显低于低分化腺癌、淋巴结转移及侵犯周围组织器官病例(P<0.05,或P<0.01);无淋巴结转移病例P63表达阳性率及其评分明显低于转移病例(P<0.05)。结论P504S和P63表达与胆囊腺癌发生发展有密切关系,P504S可能是反映胆囊腺癌生物学行为和预后的重要生物学指标。
