经病理确证的49例胃癌病人进行了手术前血清癌胚抗原(CEA)水平的检测。其中包括8例早期及41例晚期胃癌。49例胃癌CEA阳性率为44.9%(22/49),晚期胃癌阳性率为46.3%;早期胃癌为37.5%,阳性病例中77.3%患者的CEA水平在15～20μg/L,平均为17.1μg/L(正常值<15μg/L);仅4例CEA明显升高,平均为95.25μg/L结果提示只有CEA明显升高才对胃癌具有诊断价值。实验还提示血清CEA水平与肿瘤部位以及浸润深度关系不大,而与肿瘤大小,组织分化程度以及是否累及血管、淋巴管有密切关系。
Forty-four cases of gastric cancer confirmed by pathology were tested for preoperative serum levels of carcinoembryonic antigen (CEA). Including 8 cases of early and 41 cases of advanced gastric cancer. The positive rate of CEA in 49 cases of gastric cancer was 44.9% (22/49), the positive rate of advanced gastric cancer was 46.3%, the early stage gastric cancer was 37.5%, and the CEA level in 77.3% of positive cases was 15-20μg/L, with an average of 17.1μg/L. L (normal value <15μg/L); only 4 cases of CEA were significantly elevated, with an average of 95.25μg/L, suggesting that only CEA was significantly elevated was of diagnostic value for gastric cancer. The experiment also showed that the serum CEA level is not related to the tumor site and invasive depth, but it is closely related to the tumor size, degree of tissue differentiation, and involvement of blood vessels and lymphatic vessels.
