摘要 目的检测胃恶性上皮性肿瘤患者的血浆溶血磷脂(LPA)水平及其临床意义。方法检测50例胃恶性上皮性肿瘤、42例胃良性疾病患者及20例健康人血浆LPA血清癌胚抗原(CEA)的表达情况。结果胃恶性上皮性肿瘤组血浆LPA均值为7.7±3.1μmol/L,阳性率为80.0%;胃良性疾病组LPA均值为3.0±1.1μmol/L,阳性率为28.6%;健康对照组LPA均值为1.7±0.5μmol/L,阳性率为5.0%,两者间的差异有统计学意义(P<0.05)。胃恶性上皮性肿瘤的诊断中LPA的特异度为75%,高于CEA的50%;胃恶性上皮性肿瘤的诊断中两者联合检测的灵敏度最高,为92%;LPA的灵敏度为80%,高于CEA的66%,差异具有统计学意义(P<0.05)。结论胃恶性上皮性肿瘤患者血浆LPA水平明显升高,LPA诊断胃恶性上皮性肿瘤的特异性和敏感性均高于CEA,LPA有望成为胃恶性上皮性肿瘤诊断的特异性指标。
