In this study, only advanced tumor stage and CEACAM7 and CEA double-positivity were identified using the Cox proportional hazards model as independent prognostic predictors for the survival of patients with resectable gastric carcinoma, independent of age, gender, differentiation, pathologic TNM stage, lymph node metastasis, lymphatic, and venous invasion of the patients. The gene discussed is CEACAM5; the disease is gastric carcinoma.
