Developing A Prognostic Panel In Hormone Receptor Positive Breast Cancer; An Immunohistochemical Study With Clinicopathological Correlation, Shaimaa M Yussif, Reham Naguib, Nahed Soliman

Mansoura Medical Journal

Introduction

Breast cancer is a heterogeneous disease with a wide range of clinical, histological, and molecular characteristics. Various diagnostic methods have been used to ascertain prognosis by evaluating various clinicopathological data, such as tumor size, nodal stage, hormone receptor status, and human epidermal growth factor 2 (HER2) status, metastasis, tumor grade and lymphovascular emboli. Accurate substratification of prognostic groups with varying clinical outcomes is needed. This is particularly valid for cases of hormone receptor-positive breast cancer. The purpose of this study is to examine the immunohistochemical expression of a set of markers in hormone positive breast carcinoma cases and test …
