Abstract: Objective

To detect the levels of small breast epithelial mucin (SBEM),human mammaglobin(hMAM),and carcinoembryonic antigen-related cell adhesion molecule 19(CEACAM19) in serum of the patients with breast cancer, and to clarify the significances of these indicators in the early diagnosis of breast cancer and their relationships with the clinicopathological parameters of the patients.

Methods

A total of 80 patients with breast cancer were selected as breast cancer group, 58 patients with benign breast disease were selected as benign breast disease group, and 54 healthy women were selected as healthy control group. The serum levels of SBEM, hMAM,and CEACAM19 of the subjects in three groups were measured by ELISA method.The receiver operating characteristic curve(ROC) was used to analyze the area under curve (AUC),cut-off value, sensitivity and specificity of these indexes in diagnosis of breast cancer.

Results

The levels of serum SBEM, hMAM,and CEACAM19 of the patients in breast cancer group were significantly higher than those in benign breast lesion group and healthy control group (P<0.05). Compared with TNM Ⅰ-Ⅱ stages, the levels of serum SBEM, hMAM,and CEACAM19 in the patients with TNM Ⅲ-Ⅳ stages breast cancer were significantly increased (P<0.05).Compared with negative lymph node metastasis group, the serum levels of SBEM, hMAM,and CEACAM19 in the breast cancer patients with positive lymphnode metastasis were significantly increased (P<0.05).The AUC, sensitivities,and specificities of SBEM, hMAM, CEACAM19 and SBEM+hMAM+CEACAM19 in diagnosis of the breast cancer were 0.868, 80.0% and 88.4%; 0.809, 70.0% and 80.4%; 0.756, 97.5% and 50.9%; 0.913, 82.5% and 90.2%.The combined detection had the best diagnotic efficiency.

Conclusion

The combined detection of serum SBEM, hMAM and CEACAM19 has high sensitivity and specificity in diagnosis of the breast cancer, which can improve the early diagnotic efficiency of the breast cancer patients.
