Association between preoperative plasma CEA levels and the prognosis of gastric cancer following curative resection. Tumor Marker Committee, Japanese Foundation for Multidisciplinary Treatment of Cancer, Tokyo, Japan.
A large-scale retrospective study was undertaken to evaluate the association between preoperative plasma carcinoembryonic antigen (CEA) levels and the prognosis of 2768 gastric cancer patients who underwent curative gastrectomy between 1983 and 1984 at 66 leading medical institutions in Japan Postoperative follow-up was at least 5 years. Preoperative plasma CEA levels were also analysed against other prognostic factors. Preoperative plasma CEA levels showed strong correlations to the degree of lymph node metastasis (P < 0.001), TNM stage (P = 0.004) and the histopathology of the gastric cancer (P < 0.001). Preoperative CEA levels were also evaluated against survival, after being adjusted for the effect of clinically important factors by multivariate analysis. Patients with lower preoperative plasma CEA levels survived significantly longer than patients with higher CEA levels (P = 0.0001). This analysis demonstrates that curatively resected gastric cancer patients with higher preoperative plasma CEA levels have a poorer prognosis than those with lower levels, despite the adjustment for the effects of major prognostic factors.
