BRMS1 in different breast tissues, lymph node metastasis (LNM) status, tumor-node-metastasis (TNM) stages, tumor size, histological grades, pathological types, estrogen receptor (ER) status, progesterone receptor (PR) status, overall survival (OS), and relapse free survival (RFS) expressions were all compared in this meta-analysis. Here, ESR1 is linked to metastatic malignant neoplasm in the lymph nodes.
