Abstract:

Objective To explore the prognostic role of preoperative serum carcinoembryonic antigen(CEA) levels in non-small cell lung cancer(NSCLC) patients. Methods Electronic databases updated to June 1, 2014 were searched to find relevant studies. A meta-analysis was made with eligible studies which quantitatively evaluated the relationship between preoperative serum CEA level and survival of patients with NSCLC. Survival data were aggregated and quantitatively analyzed. Results Totally 16 studies(n=4 296 patients) were enrolled. We evaluated the correlation between preoperative serum CEA level and survival in patients with NSCLC. Combined hazard ratios suggested that preoperative serum CEA overexpression was associated with poor prognosis of overall survival(OS)(HR=2.28, 95% CI: 2.24-2.31) in patients. Meanwhile, for p-stage I NSCLC, the HR(95% CI) was 1.98(1.73-2.15). In the stratified analysis by patient source, significant risks were found among Asians and non-Asians. However, significant heterogeneity was observed among all studies. Conclusion In the present meta-analysis, preoperative serum CEA overexpression indicated a poor prognosis for patients with NSCLC.
