Carcinoembryonic antigen rarely exceeds serum levels of 10-12 ng/mL in benign diseases and has never been found above 24 ng/ml. We report a case in which carcinoembryonic antigen serum levels reached the value of 44.9 ng/ml without any overt reason (after 22 months of follow-up). A decline of the carcinoembryonic antigen to normal ranges was noticed after a radiolabeled anti-carcinoembryonic antigen monoclonal antibody scan was performed. The reason for this phenomenon is unclear.
癌胚抗原在良性疾病中很少超过血清水平10 - 12 ng/mL，从未发现超过24 ng/ml。我们报告一例癌胚抗原血清水平无明显原因达到44.9 ng/ml的病例（随访22个月后）。在进行放射性标记的抗癌胚抗原单克隆抗体扫描后，癌胚抗原下降至正常范围。这种现象的原因尚不清楚。
