To date no general agreement has been reached regarding the prognostic significance of CEA, CA 19-9 and CA 72-4 as serum markers in gastric cancer, and only scattered information is available on the predictive value of marker expression in tumor tissue. Therefore, a longitudinal study was designed to analyze the presurgical serum and tumor tissue content of CA 72-4, CEA and CA 19-9 in 166 patients at different stages of gastric cancer, and to evaluate the possible correlation with clinicopathological features in respect to prognostic information on relapse-free survival. The results obtained showed that 48.4% of patients with tumor recurrence had positive presurgical CA 72-4 levels compared to approximately 24% of patients who remained free of disease. Furthermore, the median presurgical serum CA 72-4 levels were significantly elevated in relapsing patients. Serosa and lymph node involvement as well as positive presurgical serum CA 72-4 levels had independent prognostic value in predicting recurrence. A significant association between disease-free survival and lymph node involvement, depth of invasion and tumor tissue content of CA 72-4 was also demonstrated. We may therefore conclude that CA 72-4 antigen can be considered the marker of choice in the follow-up of gastric cancer patients and may be used as a prognostic indicator of relapse.
