Abstract： 目的 探讨血清肿瘤标志物CEA、CA19-9、CA50水平与胰腺癌分期和肿瘤大小的关系.方法 分别测定35例胰腺癌和36例慢性胰腺炎患者血清CEA、CA19-9与CA50水平.外科手术和(或)病理学判定TNM分期和肿瘤大小,分析两者之间的关系.结果 血清CEA、CA19-9、CA50对胰腺癌诊断的敏感性分别为42%、82%、74%.特异性分别为75%、83%、77%.Ⅲ + Ⅳ期的CA19-9和CA50水平明显高于Ⅰ + Ⅱ期患者(P ＜ 0.05),CEA超过正常值者仅见于Ⅲ期以上胰腺癌患者.TS3 + TS4组的CEA、CA19-9、CA50水平比TS1 + TS2组明显增高(P ＜ 0.05).结论 胰腺癌血清CEA、CA19-9、CA50水平与胰腺癌分期和肿瘤大小有一定相关性,对手术前判断胰腺癌的可切除性有一定的参考价值.
