대장직장암 환자의 술전 및 술후 혈청 CEA측정의 의의 = Clinical Value of Preoperative and Postoperative Check of Plasma CEA Levels in Colorectal Cancer

다국어 초록 (Multilingual Abstract)

This report is a clinical study of the significance of preoperative and postoperative serial check of plasma CEA levels in 36 cases of colorectal cancer who were admitted and treated at the Chungnam National University Hospital from Mar. 1987 to Oct. 1988 and the results were as follows:
1. The positive rate of preoperative CEA level(over 5ng/ml) in colorectal cancer was 58.3% In resection group, positive rate and mean CEA level were 53.6% and 7.6ng/ml respective and in unresection group they were 75% and 36.7ng/ml respectively (p<0.05).
2. The proportion of patients with abnormal CEA level(over 5ng/ml)was 33.3% in Dukes B, 46.2% in Dukes' C and 69.2% in Dukes'D.
3. The proportion of patients with abnormal CEA level(over 5ng/ml) was 25% in wel1.diffe rentiated type, 60.9%in moderately differentiated type and 37.5 % in poorly differentiated type.
4. The recurrence rate after curative resection in preoperative normal CEA(0~2.5ng/ml) group was presumed 0% in borderline(2.6~ 5ng/ml) group was 33.3%, in high(over 5ng/ml) group was 16.7%
5. In 3 patients with postoperative liver metastasis had the highest frequency of elevated level(over 60ng/ml), whereas those with local recurrence had a lower frequency of elevated level.
6, A patient had second look procedure include segmental resection of local recurrence, buthe was dead of peritoneal caricinomatosis several months later.
