Other clinicopathological variables, such as age (P = 0.005), hypoalbuminemia (P = 0.019), elevated preoperative CEA (P < 0.001), elevated preoperative CA19-9 (P < 0.001), clinical T stage (P = 0.001), differentiation (P < 0.001), histopathology (P = 0.023), peritoneal metastasis (P < 0.001), multiple metastasis (P < 0.001), pathological T stage (P = 0.002), pathological N stage (P < 0.001), and post-operative chemotherapy (P < 0.001) were significantly associated with prognosis (Table 4). The gene discussed is CEACAM5; the disease is Hypoalbuminemia.
