In a search for proteins involved in cancer metastasis, we analyzed proteomes of the human gastric cancer cell OCUM-2M and its metastatic subline OCUM-2MLN. We observed that aspartate aminotransferase (AAT), D-site binding protein (DBP), and anterior gradient protein 2 (AGR2) are differentially expressed in metastatic OCUM-2MLN cells. Measurement of protein expression in clinical samples indicated that DBP and AAT are also down-regulated in metastatic adenocarcinoma. Additionally, urokinase-type tissue plasminogen activator is up-regulated in OCUM-2MLN cells and also in metastatic gastric cancer samples. Collectively, these results raise a possibility that AAT, DBP and AGR2 are functionally implicated in the invasiveness of gastric cancer cells.

To assess whether preoperative markers could predict the stage of patients with gastric cancer. We analyzed retrospectively the preoperative indicators between stage IV and non-stage IV gastric cancer at the Gastrointestinal Surgery of Nanjing Drum Tower Hospital. A total of 500 patients with gastric cancer were screened. Of all the variables, alpha-fetoprotein (AFP), carcinoembryonic antigen (CEA), carbohydrate antigen (CA) 125, carbohydrate antigen (CA) 199, carbohydrate antigen (CA) 724, carbohydrate antigen (CA) 242, thrombin time (TT), prothrombin time (PT), activated partial thromboplastin time (APTT), blood platelet count (PLT), white blood cell (WBC) count, C-reactive protein (CRP), neutrophil count (NC), lymphocyte count (LC), neutrophil-lymphocyte ratio (NLR), hemoglobin (HB), aspartate aminotransferase (AST), and ascites were found to have statistical differences between the two groups. Then, Stepwise Discriminant Analysis was conducted to establish a prediction model including 7 indexes (CA724, CA242, TT, PLT, CRP, AST, and ascites). According to the model, 90.6% of original grouped cases were correctly classified and 90.6% of cross-validated grouped cases were correctly classified. We built a discriminant including CA724, CA242, TT, PLT, CRP, AST, and ascites for predicting patients with gastric cancer to be either stage IV or non-stage IV. According to this discriminant, 90.6% of patients could be correctly predicted.
