AIM: To evaluate pretreatment serum carcinoembryonic antigen (CEA) as a predictor of survival for patients with locally advanced gastric cancer receiving perioperative chemotherapy. METHODS: We retrospectively studied a cohort of 228 gastric cancer patients who underwent D2 gastrectomy combined with chemotherapy at the Sun Yat-sen University Cancer Center between January 2005 and December 2009. Among them, 168 patients received 6-12 cycles of oxaliplatin-based adjuvant (post-operative) chemotherapy, while 60 received perioperative chemotherapy (2 cycles of FOLFOX6 or XELOX before surgery and 4-10 cycles after surgery). Serum CEA was measured using an enzyme immunoassay. The follow-up lasted until December 2010. RESULTS: In the group that had elevated serum CEA, the difference in survival time between patients receiving perioperative chemotherapy and those receiving adjuvant chemotherapy had no statistical significance (P > 0.05). However, in the group that had normal serum CEA, patients receiving perioperative chemotherapy had a longer survival time. In multivariate analysis, T staging and lymph node metastatic rate were independent prognostic factors for the patients. Perioperative chemotherapy improved the overall survival of patients who had a normal pretreatment CEA level (P = 0.070). CONCLUSION: Normal pretreatment serum CEA is a predictor of survival for patients receiving perioperative chemotherapy.
