ESR1 and breast cancer: We found that miR-200c levels were inversely correlated with clinical stage, local relapse and distant metastasis (P = 0.017, 0.019 and 0.033 respectively) (Table 1) but not correlated with age, menopause, tumor size, lymph node metastasis, ER, PR, HER2 and P53 status among the 134 breast cancer patients.
