Abstract:
Objective The purpose of this study is to explore the expression of 12 tumor Markerss in the serum of colon cancer patients by C 12 tumor marker protein chip ,screening most valuable Markers for diagnosis . Methods C12 tumor Marker of protein chips were used for 12 sorts of tumor marker detection among 60 CRC patients and 40 healthy controls ,address the most valuable tumor marker relative to colon cancer and contribution of combinations effect on diagnosis .Result CEA+CA199+CA242+Bete-HCG combination diagnosis has the highest effectivity and diagnosis sensitivity was greatly improved by combination detection .The optimized diagno-sis showed no significant tendency to be correlated with age ,sex,differentiation stage,pathology,Lymph node me-tastasis,clinical stage.Conclusion It is of importance to use sera CEA +CA199+CA242+Bete-HCG detec-tion as markers for colon cancer diagnosis ,which may improve diagnosis efficiency .
