Despite advances in the early detection and treatment of breast cancer, it remains a challenge to identify which patients may experience a poor prognosis or respond poorly to treatment.

Objective: The role of hormone receptors as a prognostic and therapeutic tool in breast cancer is widely accepted. The aim of this study was to the analysis of steroid receptor status in breast cancer with clinic pathological characteristics. Methods: In the present study, immunohistochemical assay of two hundred tumor block of patients of breast carcinoma was performed to know the hormone receptor status as well as histological examination. Results: samples were grouped to study hormonal status and their relation with clinic-pathological factors. The results in the present study documented the


Prognostic factors can be useful for making decisions about which patients should receive adjuvant therapy, and predictive factors can be used to predict response or lack of response to a particular therapy. We review the standard factors that are available today for primary breast cancer, and we describe some of the new, potential prognostic and predictive factors that are currently under investigation.

Predictive factors of breast cancer evaluated by immunohistochemistry. Hormone receptor and Her2 protein overexpression evaluated by immunohistochemistry IHC is widely validated as a predictive factor in breast cancer. The quality of the IHC reaction is influenced by tissue fixation and processing. Over- and underfixation deeply affect IHC results. Antigen retrieval may improve IHC but it does not recover tissue from autolysis or overfixation. The choice of primary antibody for IHC as to its sensitivity and specificity in relation to therapeutic response represents an important stage.
