The prognostic value of preoperative serum levels of CEA, CA 19-9 and CA 72-4 tumor markers was investigated in 153 patients resected for gastric cancer. The positivity rates for CEA, CA 19-9 and CA 72-4 were 20.9, 34.6 and 28.1%, respectively. Multiple logistic regression analysis for positive levels of tumor markers indicates that CEA positivity is significantly related to the depth of invasion (p < 0.005) and the presence of distant metastasis (p < 0. 05), CA 19-9 positivity is related to nodal involvement (p < 0.05) and the depth of invasion (p < 0.05), whereas CA 72-4 positivity is influenced by tumor size (p < 0.005) and noncurative surgery (p < 0. 05). Positive levels of each tumor marker were associated with a worse prognosis if compared with negative cases using univariate analysis. Multivariate analysis of curatively resected cases identified depth in gastric wall (p < 0.0001), nodal status (p < 0. 0005), and tumor location in the upper third (p < 0.05) as significant prognostic variables; CEA, CA 19-9 and CA 72-4 serum positivity did not reach statistical significance. However, when the positivity of the three markers was associated, a p value < 0.05 was observed. The analysis of survival curves stratified by tumor stage revealed that marker positivity significantly affects survival in stages I, II and IV (p < 0.05). The combined assay of CEA, CA 19-9 and CA 72-4 preoperative serum levels provides additional prognostic information in patients resected for gastric cancer; patients with preoperative positivity for one of these tumor markers should be considered at high risk of recurrence even in early stages of gastric carcinoma.
