Value of Combined Measurement of CK19, CEA and CA19-9 in the Evaluation of the Efficacy and Prognosis of Postoperative Chemotherapy in Colorectal Cancer

Objective] To explore the clinical value of combined measurement of tumor markers CK19, CEA and CA19-9 in different mechanism levels for the evaluation of the efficacy of postoperative chemotherapy in colorectal cancer. Methods] Sixty eight patients with colorectal cancer confirmed by surgical pathology were chosen. Chemiluminescence immunoassay was used to detect the level of CKI9 before and after the first course of chemotherapy and the levels of serum CEA and CA19-9 before and after full course of chemotherapy.The measurement of above markers combined with the result of follow-up tmagmg was usea to analyze tne corremtion between the combined measurement of tumor markers, tumor recurrence and chemotherapy efficacy. Results]In metastasis group, at least one marker was normal in all patients（100 %）, and at least two markers were above normal in 12 patients（75 %）, and all three markers were above normal in 4 patients（25 %）. In non- metastasis group, only one marker was normal in 22 patients（42.31 %）, and the two or three markers were normal simultaneously in none of patients. Eighteen cases in non-metastasis group, the level of CEA or CA19- 9 before chemotherapy were above positive reference, and decreased to the normal after full course of chemotherapy, and its coincidence with the regular changes of CK due to apoptosis during the initial chemotherapy was 66.7 %. Conclusion]Combined measurement of CK19, CEA and CA19-9 can predict the postoperative re- currence of colorectal cancer accurately. The characteristics of the regular change of CK19 during the initial chemotherapy have a direct correlation with the efficacy of chemotherapy, and can be the indicator of predicting the efficacy of chemotherapy, so they have an important clinical value.
