Objective To test the expressions of human mammary gland globin (hMAM) mRNA in the peripheral blood of breast cancer and breast benign lesions patients, try to provide the theory basis for the choice of breast cancer molecular marker. Methods Polymerase chain reaction (PCR) technology was used to detect the expressions of hMAM mRNA in peripheral blood of 78 cases of breast cancer patients, 15 cases of hyperplasia of mammary gland, and 15 cases of breast fibroadenoma. The relationship between the expressions of hMAM-mRNA in peripheral blood of breast cancer patients with patient's age, tumor size, pathological type, tumor stage, axillary lymph node metastasis, and the ER, PR and HER-2 status were analyzed. Results The expressions of hMAM-mRNA in peripheral blood were not detected in breast hyperplasia and breast fibroadenoma patients, but the peripheral blood hMAM-mRNA expression rate in breast cancer patients was 48.72% (38/78), the difference was statistically significant (χ2=12.357, P=0.000). The expression of peripheral blood hMAM mRNA was not related to the patient's age, tumor size, pathological type, and ER, PR and HER-2 status (P > 0.05), but the expression of peripheral blood hMAM mRNA was related to the clinical staging of tumor (Z=-2.214, P=0.027) and lymph node metastasis status (Z=-2.754, P=0.006). Conclusion Peripheral blood hMAM-mRNA detected is a sign of breast cancer, further research is needed to confirm whether hMAM mRNA detection in peripheral blood correlates with poor prognosis of breast cancer patients.
