1. CA72-4是目前诊断胃癌的最佳肿瘤标志物之一,对胃癌具有较高的特异性,其敏感性可达28%~80%,若与CA19-9及CEA联合检测可以监测70%以上的胃癌。CA72-4水平与胃癌的分期有明显的相关性,一般在胃癌的Ⅲ~Ⅳ期增高,对伴有转移的胃癌病人,CA72-4的阳性率更远远高于非转移者。CA72-4水平在术后可迅速下降至正常。在70%的复发病例中,CA72-4浓度首先升高。与其它标志物相比,CA72-4最主要的优势是其对良性病变的鉴别诊断有极高的特异性,在众多的良性胃病患者中,其检出率仅0.7%。\\

  静脉血3ml不抗凝,或红帽或黄帽真空管采血。不用血浆,因析出纤维蛋白可致假阳性反应。溶血或血清乳浊可有影响。抗原较稳定,血清室温放置1天,4℃2周、-20℃1年测定结果在允许误差范围之内。\\
