ABSTRACT
Objective:To investigate the expression level of TRPM7 in breast cancer tissues and adjacent carcinoma tissues and to analyze its clinicalpathological characteristics.Methods:The expressions of TRPM7 in 87 breast cancer and 47 adjacent tissues were detected by immunohistochemistry, and then the relationship between expression and clinicopathological characteristics was analyzed.Results:The positive rate of TRPM7 in breast cancer tissues was 66.7%, significantly higher than that in para-cancer tissues (10.6%) ( P<0.001) . Meanwhile, TRPM7 expression was much higher in those with tumor diameter≥2 cm ( P=0.023) , TNM stage III ( P=0.001) and lymph node metastasis ( P=0.015) . The expression of TRPM7 has nothing to do with patients’ age ( P=0.455) or histological grade ( P=0.577) . Conclusions:High expression of TRPM7 is associated with the development of breast cancer. TRPM7 may become a potential biological indicator to monitor the prognosis of breast cancer in the future.
