INTRODUCTION: There is little information on the oncologic diagnostic accuracy of carcinoembryonic antigen (CEA) levels more than 3-fold above normal.
OBJETIVES: To determine the prevalence of underlying cancer in patients with mild CEA elevation and the mean cost per patient of CEA determination.
METHODS: A retrospective study was carried out in all patients with CEA elevation (3-10 ng/ml) and suspicion of cancer referred to the gastroenterology or internal medicine outpatient units from 2001 to 2007.
RESULTS: We studied 100 patients (60 men and 40 women), with a mean age of 67.4 ± 14.2 years and baseline CEA of 5.8 ± 1.7 ng/ml. The most important symptoms and signs were laboratory abnormalities (19 patients [19%]). Cancer was diagnosed in 4 patients (one gastric, 2 lung and one colon). Among patients without malignancies, 49 patients (49%) had no related processes, and 47 (47%) had benign diseases. During follow-up, one laryngeal cancer, one acute myeloid leukemia, and one colon cancer were detected (54.3 ± 24.6 months). We found no differences between baseline CEA levels in patients with and without cancer (6.6 ± 2.4 vs. 5.8 ± 1.7 ng/ml, p = 0.2). The mean cost per patient was 503.6 ± 257.6 €.
CONCLUSIONS: Cancer was detected in a small proportion (7%) of patients with mild CEA elevation. The study of these patients is directly and indirectly associated with a not inconsiderable cost.
