Background and AimsCarcinoembryonic antigen (CEA) is the most commonly used tumor marker for gastrointestinal cancers but its value for resectable gastric adenocarcinoma (RGA) patients in areas of high GA incidence is uncertain.MethodsWe retrospectively studied 400 subjects with RGA from the Fujian Province in China, which has a high incidence of GA. Patients had surgery between January 2010 and December 2013. CEA was measured and correlated to pathology.ResultsHigh pretreatment serum CEA (>5 ng/mL) was associated with patient age (p = 0.000), tumor size (p = 0.008), and T and N stages (p = 0.002, p = 0.032, respectively), alpha fetoprotein (p = 0.014), and CA19-9 (p = 0.000). High CEA was significantly associated with poor overall survival. Overall survival in the whole group of patients was 63.8%, whereas it was only 42.9% in the high CEA group (p = 0.0001). Mean overall survival for high CEA patients was significantly shorter than patients with low CEA (36.5 ± 2.63 months vs. 47.4 ± 0.98 months, p = 0.000). Multivariate analysis confirmed that pretreatment serum CEA was an independent prognostic factor for increased death risk. Additionally, mean CEA in 45 high CEA patients was reduced after surgery.ConclusionsPretreatment serum CEA may help to predict survival for patients with RGA in high GA incidence areas.
