82% of the cancer patients and 52% of the patients with polyps showed CEA levels above the upper normal limit of 2,5 microgram/1. CEA-values of more than 10 microgram/1 could only be detected in patients with carcinoma. Complete removal of the tumour by surgery has been followed by a marked decrease of prior increased plasma-CEA to values in the normal range, which could not be observed in the cases with tumour residues or metastases. In the patient's follow-up recurrence or metastases could be recognized several months before clinical detection by a renewed increased of the CEA-level in plasma.
82%的癌症患者和52%的息肉患者癌胚抗原（CEA）水平高于2.5微克/升的正常上限。仅在癌症患者中检测到癌胚抗原值超过10微克/升。手术完全切除肿瘤后，先前升高的血浆癌胚抗原显著下降至正常范围，而在有肿瘤残留或转移的病例中未观察到这种情况。在患者随访过程中，血浆癌胚抗原水平再次升高可在临床检测前数月识别复发或转移。
