The objective of this study was to assess the frequency and characteristics of false-positive results for tumor markers after curative gastrectomy for gastric cancer. Carcinoembryonic antigen and/or carbohydrate antigen 19-9 were periodically assessed for 168 patients who underwent curative gastrectomy. Cancer recurrence was observed for 17 (10.1%) patients and 151 (89.9%) were disease-free during the mean follow-up period of 23.1 months after the operation. The frequency of false-positive… CONTINUE READING
