The Significance Of CEA, CA19-9 In Predicting Liver Metastases Of Patients With Gastrointestinal Tumor

Objective:Determination the serum CEA and CA19-9 of colorectal cancer and gastric cancer by ECLI, explore the relationship between serum CEA、CA19-9 and colorectal 、gastric cancer patients with liver metastasis. Methods:Select 111 cases of colorectal cancer(CRC) patients and 75 cases of gastric cancer patients in this study. Gastric cancer and colorectal cancer are different groups, each group was further divided into liver metastasis and no liver metastasis group. Compare liver transfer rate of liver metastasis and no liver metastasis difference in serum tumor markers CEA, CA19-9, sex, age, tumor size, ascites, hepatitis by SPSS19.0 statistical software and Chi-square test. Result:1. When the serum tumor markers are positive, the opportunity of happening liver metastases in colorectal cancer is higher than the serum tumor markers are negative; as the serum tumor markers CEA, CA19-9 concentration increased in colorectal cancer with liver metastasis, the liver transfer rate is gradually increased, and the difference between different concentrations were statistically significant, p <0.05. The liver transfer rate has no significant differences in sex, age, tumor size, whether there is ascites in colorectal cancer, p> 0.05.2.When the serum tumor markers are positive, the opportunity of happening liver metastases in gastric cancer is higher than the serum tumor markers are negative; as the serum tumor markers CEA, CA19-9 concentration increased in gastric cancer with liver metastasis, the liver transfer rate is gradually increased, and the difference between different concentrations were statistically significant, p <0.05. The liver transfer rate has no significant differences in sex, age, tumor size, whether there is ascites in gastric cancer, p> 0.05. Conclusion:CEA and CA19-9 can prompt that the occurrence of liver metastases in gastric cancer、colorectal cancer, when the CEA or CA19-9 is positive, gastric cancer、colorectal cancer patients have high possibility of liver metastases; the probability of liver metastasis gradually increased with the serum tumor markers CEA, CA19-9 concentration increased in gastric cancer, colorectal cancer.
