Method we selected February 2015 to February 2017 in our line of surgical treatment of 198 cases of CRC patients as the research object, analyzed the CEA and CA19-9 patients and their ratio relation with the pathological parameters and survival prognosis of CRC patients, and analyze the risk factors affecting the prognosis of patients with CRC. Result There were significant differences between preoperative CEA positive and distant metastasis and TNM stage.There was significant difference between CA19-9 positive before surgery and distant metastasis, TNM stage, depth of tumor invasion, lymph node metastasis and degree of tumor differentiation. Postoperative CEA positive was significantly correlated with distant metastasis and TNM stage. Postoperative CA19-9 positive was significantly correlated with distant metastasis, TNM stage and lymph node metastasis. The postoperative CEA positive, the preoperative CA19-9 positive, the postoperative CA19-9 positive, the CEA ratio>1, the CA19-9 ratio BBB>and the postoperative 3-year overall survival of CRC patients were significantly shortened (P<0.05). Preoperative positive CA19-9, CEA ratio>1, CA19-9 ratio>1, lymph node metastasis and distant tumor metastasis were independent risk factors affecting postoperative prognosis of patients with CRC. Conclusion Preoperative CA19-9 elevation, postoperative CEA/preoperative CEA ratio>1, postoperative CA19-9/ preoperative CA19-9 ratio>1 are independent risk factors affecting postoperative prognosis of patients with CRC.
