Moreover, we found that GATA3 association with OS was also maintained in individual BC subgroups, particularly those at lower risk, such as ER-positive, PR-positive, HER2-negative, with lower proliferation (ki-67 < 20%), p53 wild-type, lower grade, smaller size (pT1–T2), without lymph node metastasis (pN0), at lower stage, and older than 50 years. This evidence concerns the gene TP53 and metastatic malignant neoplasm in the lymph nodes.
