Abstract:
摘要 目的 检测KIF3A在不同病变胃组织及淋巴结转移灶中的表达，探讨其与胃腺癌发生、转移、临床病理特征及预后的关系。方法 应用免疫组织化学技术检测不同胃组织及淋巴结转移灶中KIF3A的表达。采用SPSS23.0软件包对数据进行统计分析。结果 KIF3A在胃腺癌组织中的表达水平明显高于癌旁相对正常组织（P<0.01），而淋巴结转移灶中的表达水平较相应原发灶中更高（P<0.01）；低级别、高级别上皮内瘤变中KIF3A的表达水平均明显高于慢性胃炎组织（P<0.01）；KIF3A的表达与进展期胃腺癌患者的TNM分期、淋巴结转移、脉管侵犯相关（P<0.05）；进展期胃腺癌患者中，KIF3A高表达者总体生存和无病生存时间较低表达者明显缩短（P<0.01），且KIF3A在细胞质及细胞核都有表达者总体生存时间较仅细胞质表达者短（P<0.05）； Cox多因素分析显示，KIF3A是胃腺癌患者总体生存期与无病生存期的独立危险因素（P<0.05）。结论 KIF3A可能与胃黏膜上皮内瘤变的发生有关，其表达增强和核表达可能与进展期胃腺癌患者预后不良有关，是进展期胃腺癌患者的独立预后因素
