Clinicopathological factors associated with novel prognostic markers for patients with triple negative breast cancer.

Introduction: Triple negative breast cancer (TNBC) is characterized by a worse prognosis than other breast cancer subtypes. TNBC is defined by lack of expression of estrogen receptor, progesterone receptor and human epidermal growth factor receptor 2. The aim of this analysis was to evaluate the relationship between immunohistochemical expression of novel prognostic markers (erythropoietin (EPO) and erythropoietin receptor (EPO-R)) and clinicopathological features of TNBC and non-TNBC patients.

Medullary breast cancer is a predominantly triple-negative breast cancer - histopathological analysis and comparison with invasive ductal breast cancer.

Introduction: Medullary breast cancer (MdBC) is an uncommon type of breast cancer representing 1-7% of all cases. It is characterized by the occurrence of many histopathological features associated with a high grade of malignancy.

Material And Methods: Twelve MdBCs chosen from a group of 1,122 women suffering from invasive breast cancer were analyzed.
