Elevated carbohydrate antigen 19-9 (CA19-9) beyond 1000 U/L occurs in nonneoplastic conditions which is causing questioning of the use of CA19-9 as a marker for screening. We report a case where a 51-year-old male with Mirrizi Syndrome (MS) presented with markedly increased CA19-9 level (4,618 U/mL). MS is a rare complication characterized by compression of the common bile or hepatic duct caused by an impacted gallstone in the cystic duct or neck of the gallbladder. Biliary epithelial cells secrete CA19-9: it is hypothesized that increased proliferation of such cells caused by inflammation leads to increased secretion. CA19-9 should not be used as a diagnostic tool, but rather for surveillance.
糖类抗原19-9(CA19-9)水平超过1000 U/L也会出现在非肿瘤性疾病中,这引发了对将CA19-9用作筛查标志物的质疑。我们报告了一例51岁患有Mirrizi综合征(MS)的男性患者,其CA19-9水平显著升高(4618 U/mL)。MS是一种罕见的并发症,其特征是胆囊管或胆囊颈部的结石嵌顿导致胆总管或肝管受压。胆管上皮细胞分泌CA19-9:据推测,炎症引起的此类细胞增殖增加会导致分泌增加。CA19-9不应用作诊断工具,而应用于监测。
