Objective   To investigate the clinical and pathological factors associated with simultaneity peritoneal metastasis of colorectal cancer. Methods  Clinical data of 1 593 patients with simultaneity peritoneal metastasis of colorectal cancer who treated in Suqian People’s Hospital and Nanjing Drum Tower Hospital from 2010-2014 were collected to analyze the risk factors of simultaneity peritoneal metastasis of colorectal cancer. Results  There were 40 patients (2.5%) suffered form simultaneity peritoneal metastasis of the 1 593 patients with colorectal cancer. The result of univariate analysis showed that, age, diameter of tumor, level of carcino-embryonic antigen (CEA), level of CA19-9, level of CA-125, T staging, differentiation, pathological type, and combining with diabetes were risk factors of simultaneity peritoneal metastasis of colorectal cancer, that incidence rates of simultaneity peritoneal metastasis in patients with ≥ 65 years old, diameter ≥ 5 cm, increase of CEA, CA19-9, and CA-125, later staging of T staging, poorly differentiated, signet ring cell carcinoma/mucinous adenocarcinoma, and combining with diabetes were higher (P<0.05). The result of logistic regression showed that, level of CA19-9, level of CA-125, T staging, combining with diabetes, differentiation, and pathological type were the risk factors of simultaneity peritoneal metastasis of colorectal cancer, that incidence rates of simultaneity peritoneal metastasis in patients with increase of CEA and CA-125, later staging of T staging, poorly differentiated (compared with well differentiated), mucinous adenocarcinoma (compared with adenocarcinoma), and combining with diabetes were higher (P<0.05). Conclusion  Increase of CEA and CA-125, T staging, poorly differentiated, mucinous adenocarcinoma, and combining with diabetes are independent risk factors for simultaneity peritoneal metastasis of colorectal cancer.
