The serum levels of CA 19-9 and carcinoembryonic antigen (CEA) were determined in 37 patients with benign colorectal diseases and in 111 patients with newly discovered colorectal carcinomas or clinically verified relapses. In cancer patients, the CA 19-9 level ranged from normal (0-37 U ml-1) to 77,500 U ml-1 whereas all samples but one from patients with benign colorectal diseases had a normal value. CA 19-9 was increased in 46% and 45% of patients with an advanced (Dukes C or D) carcinoma or a verified recidive, respectively. Only one out of 26 patients (4%) with a localized (Dukes A or B) carcinoma displayed an elevated CA 19-9 level (greater than 37 U ml-1). No clear correlation was found between the CA 19-9 and CEA levels. The sensitivity of the CA 19-9 test (36%) was poorer than that of the CEA assay (69%), but the new test was markedly more specific (97% vs 70%) than the CEA assay.
对37例良性结直肠疾病患者和111例新发现的结直肠癌患者或经临床证实复发的患者测定了血清CA 19-9和癌胚抗原(CEA)水平。在癌症患者中,CA 19-9水平范围从正常(0 - 37 U/ml)到77,500 U/ml,而除1例样本外,所有良性结直肠疾病患者的样本值均正常。分别有46%和45%的晚期(杜克C或D期)癌或经证实复发的患者CA 19-9升高。在26例局限性(杜克A或B期)癌患者中,仅1例(4%)的CA 19-9水平升高(大于37 U/ml)。未发现CA 19-9和CEA水平之间存在明显相关性。CA 19-9检测的敏感性(36%)低于CEA检测(69%),但新检测的特异性(97%对70%)明显高于CEA检测。
