Furthermore, the preliminary results indicated that it might be related to apoptosis and metastasis.15 Herein, we used tissue microarrays and widened the number of breast cancer samples to (1) further clarify the association between FLI‐1 and various molecular subtypes and (2) evaluate the prognostic value of FLI‐1 in the patients with breast cancer. Here, FLI1 is linked to breast carcinoma.
