The role of the preoperative serum carcinoembryonic antigen level in early-stage adenocarcinoma of the uterine cervix.

Abstract Objective. The purpose of the study was to identify the relationship between preoperative serum levels of carcinoembryonic antigen (CEA) and clinicopathological variables in early-stage adenocarcinoma of the uterine cervix. Methods. From February 1990 to August 2002, 117 patients with surgically treated early-stage cervical adenocarcinoma that had had preoperative serum CEA evaluations were retrospectively reviewed. The cut-off value for CEA, based on the manufacturer's recommendations, was 5 ng/ml. For an evaluation of the relationship between the clinicopathological factors and increased levels of serum tumor markers, the Chi-Square/Fisher's exact test and logistic regression were used for univariate and multivariate analysis, respectively. Results. The mean age of the patients was 46 years (range, 21–78). Of the 117 patients, 28 had preoperative serum CEA levels greater than 5 ng/ml. In a univariate analysis, the increased marker was associated with a larger tumor size, presence of lymphovascular invasion, and deeper cervical wall invasion. However, in a multivariate analysis, the preoperative CEA level had a significant impact on the determination of the depth of stromal invasion (OR 4.12, 95% CI 1.97–8.68, P Conclusion. In early-stage cervical adenocarcinoma, preoperative serum CEA levels seem to be useful in estimating the depth of cervical stromal invasion. Assessment of tumor antigen CEA levels should be integrated with the routine examination in the work-up of patients with adenocarcinoma of the uterine cervix.
