报告EIA法测定血清CA242的临床意义。同时对CA242与CEA诊断肿瘤的关系作了讨论。结果表明：CA242与CEA在肿瘤诊断的相关性不完全一致，作为腺癌的单项指标CA242优于CEA，二者合用可提高腺癌的诊断率（肺腺癌76％；直肠腺癌79％；胰腺癌100％；食管或乳腺癌62％）。CA242可作为肿瘤组织学类型及病程估计。93树参考人群CA242结果为10．2±2．7U／ml；肿瘤与非肿瘤组差别显著（P＜0.01），本文资料说明：CA242是腺癌的良好标志，特别提示是胰腺癌的特异指标。
The clinical significance of measuring serum CA242 by EIA method was reported. At the same time, the relationship between CA242 and CEA in the diagnosis of tumor was discussed. The results showed that the correlation between CA242 and CEA in tumor diagnosis was not completely consistent. As a single index of adenocarcinoma, CA242 was better than CEA. The combination of the two could increase the diagnostic rate of adenocarcinoma (76% for lung adenocarcinoma; 79% for rectal adenocarcinoma; Pancreatic cancer 100%; esophagus or breast cancer 62%). CA242 can be used as a tumor histological type and course estimation. The reference CA242 of the 93 tree reference population was 10.2±2.7 U/ml; the difference between the tumor and non-tumor group was significant (P<0.01). The data showed that: CA242 is a good marker of adenocarcinoma, and the special tip is a specific indicator of pancreatic cancer. .
