摘要 目的观察肿瘤患者外周血中抗精子相关抗原-9自身抗体的表达情况并进行详细分析,旨在更好地作为临床指导加以应用。方法80例癌症患者和健康对照组人员均空腹后进行血液采集,每人采集血液3~5mL,静置一段时间后3000r/min离心10min,取上清液置于-80℃冰箱保存。SPAG9的检测采用APAG9重组蛋白作为抗原建立ELISA,对SPAG9对肿瘤患者引起的体液免疫反应进行分析,以健康组作为对照。对所得数据结果做统计分析。结果SPAG9免疫反应的总体阳性率为30%,29例肝癌患者的阳性率为40%,32例肺癌患者的阳性率20%,其他19例癌症患者的阳性率为43%;健康对照组的阳性率仅为6%,与癌症患者比较有显著性差异(P〈0.05);肝癌组和其他癌症组的OD值均比较分散,出现有较强的免疫反应患者;相反,肺癌组患者的OD值显示较为集中且无强免疫反应患者出现。结论患者外周血中抗精子相关抗原-9自身抗体的表达情况依所患疾病而有所不同,但均能够较好地作为癌症诊断和治疗的参考标准。
