The most common characteristics were as follows: age 35–50 at diagnosis (n = 1,320 [54.8%]); T2 stage disease (n = 1,123 [46.9%]); positive regional lymph node metastasis (n = 1,315 [54.6%]); histologic grade 3 (n = 1,050 [49.7%]); hormone receptor-positive and HER2-negative (n = 1,076 [46.3%]). This evidence concerns the gene NR4A1 and metastatic malignant neoplasm in the lymph nodes.
