In the univariate analysis, prognostic factors for DFS were T4 stage (p = 0.0018), preoperative anemia (p = 0.0019), and preoperative thrombocytopenia (p = 0.0444), and prognostic factors for OS were T4 stage (p = 0.005), preoperative anemia (p = 0.0143), preoperative thrombocytopenia (p = 0.0485), postoperative carcinoembryonic antigen (CEA) (p = 0.0019), and low albumin level (p = 0.0298) (Table 2). This evidence concerns the gene ALB and Thrombocytopenia.
