摘要 为探讨胆管癌和先天性胆总管囊性扩张症中肿瘤坏死因子α(TNF-α)及肿瘤坏死因子受体Ⅰ(TNFR-Ⅰ)表达的差异。笔者选取经外科手术切除的胆管癌患者48例,先天性胆总管囊性扩张症19例,用免疫组化SP法检测TNF-α和TNFR-Ⅰ的表达。结果示,TNF-α在胆管癌和先天性胆总管囊性扩张症中表达阳性率分别为25.0%(12/48)和5.3%(1/19),两者差异有显著性(P<0.05)。TNFR-Ⅰ在胆管癌和先天性胆总管囊性扩张症中表达阳性率分别为75.0%(36/48)和42.1%(8/19),两者差异有非常显著性(P<0.01)。提示胆管癌和先天性胆总管囊性扩张症组织中均可表达TNF-α和TNFR-Ⅰ,但胆管癌中的表达明显增强。TNF-α和TNFR-Ⅰ可能参与先天性胆总管囊性扩张症的恶变过程,其表达情况有可能可作为监测胆管良恶性病变的参考指标之一。
