Diagnostic value of single and combined detection of serum carcinoembryonic antigen,carbohydrate antigen 125 and carbohydrate antigen 153 for breast cancer
Objective To investigate the diagnostic value of single and combined detection of serum carcinoembryon-ic antigen(CEA),carbohydrate antigen(CA)125 and CA153 for breast cancer.Method Atotal of 172 breast disease pa-tients underwent breast surgery were selected and divided into breast cancer group(92 cases)and benign breast lesion group(80 cases)according to the postoperative pathological results.Another 80 healthy patients were selected as the healthy group.The levels and positive expression rates of CEA,CA125 and CA153 in three groups,and the positive ex-pression rates of CEA,CA125 and CA153 in breast cancer patients with different pathological characteristics were com-pared.Pathological examination results were used as the gold standard,the diagnostic value of CEA,CA125 and CA153 single and combined detection for breast cancer were compared.Result The levels and positive expression rates of CEA,CA125 and CA153 in breast cancer group were higher than those in benign breast lesion group and healthy group,and the differences were statistically significant(P<0.05).The positive expression rates of CEA,CA125 and CA153 in breast cancer patients with clinical stage Ⅲ-Ⅳ,tumor size≥5 cm and lymph node metastasis were higher than those in breast cancer patients with clinical stage Ⅰ-Ⅱ,tumor size<5 cm and no lymph node metastasis,and the differences were statistically significant(P<0.05).The accuracy and sensitivity of CEA,CA125 and CA153 combined detection in the di-agnosis of breast cancer were higher than those of each index single detection.Conclusion The expression levels and positive expression rates of CEA,CA125 and CA153 in breast cancer patients are high,which are related to the occur-rence and development of breast cancer.The combined detection of CEA,CA125 and CA153 is of high diagnostic value for breast cancer.
