我们前瞻性地对117例大肠癌用放免法测定手术前和(或)手术后血清CEA,旨在估价大肠癌手术前后CEA值变化的临床意义.结果提示术后CEA值显著升高或持续进行性升高者,多为癌复发、扩散或远处转移.CEA浓度正常也可见于晚期癌患者
We prospectively measured the preoperative and/or postoperative serum CEA by radioimmunoassay in 117 patients with colorectal cancer, aiming to evaluate the clinical significance of changes in CEA before and after colorectal cancer surgery. The results suggest that postoperative CEA values are significantly increased or continued. Those who have elevated sex are mostly cancer recurrence, spread, or distant metastases. Normal CEA concentrations can also be seen in patients with advanced cancer.
