Streamline Breast Immunohistochemistry QC Monitoring

Introduction

Breast cancer is a significant global health concern, affecting millions of women each year. As medical professionals, accurately diagnosing and characterizing breast tumors is of paramount importance for guiding treatment decisions. Immunohistochemistry (IHC) plays a pivotal role in identifying and assessing the expression of specific biomarkers within breast tissue samples, enabling clinicians to tailor therapies to individual patients. In this blog post, we will explore four commonly used markers in breast IHC: estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and Ki67. Additionally, we will introduce a powerful tool to enhance your breast IHC quality control (QC) monitoring—the breast IHC QC monitoring template 

Estrogen Receptor (ER)

The estrogen receptor (ER) is a nuclear receptor that regulates gene expression in response to estrogen signaling. ER expression in breast tumors helps to determine the hormonal dependency of the cancer and guide treatment decisions. The immunohistochemical staining of ER allows for the visualization and assessment of ER expression in breast tissue samples. The breast IHC QC monitoring template incorporates standardized guidelines to ensure accurate ER assessment, facilitating the evaluation of ER-positive and ER-negative tumor samples.

Progesterone Receptor (PR)

Similar to ER, progesterone receptor (PR) expression in breast cancer cells helps to establish the hormonal status of the tumor. Immunohistochemistry plays a crucial role in detecting and quantifying PR expression. The breast IHC QC monitoring template includes provisions for PR assessment, aiding in the identification and characterization of PR-positive and PR-negative tumor samples.

Human Epidermal Growth Factor Receptor 2 (HER2)

HER2 is a transmembrane receptor protein that plays a significant role in cell growth and division. Overexpression or amplification of HER2 in breast cancer is associated with a more aggressive tumor phenotype. Immunohistochemistry enables the visualization of HER2 protein expression in breast tissue samples, thereby assisting in the determination of HER2 status. Our breast IHC QC monitoring template provides a standardized approach to assess HER2 staining, ensuring accurate identification of HER2-positive and HER2-negative tumors.

Ki67

Ki67 is a proliferation marker that helps evaluate the growth rate of cancer cells. High Ki67 expression often indicates a more aggressive tumor with a higher likelihood of rapid proliferation. Immunohistochemical staining for Ki67 aids in the identification and quantification of proliferating cells within breast cancer tissue samples. The breast IHC QC monitoring template incorporates guidelines to assess Ki67 staining, facilitating the determination of Ki67 index and aiding in tumor grading.
