Abstract:
The epidermal growth factor receptor (EGFR) is a member of the ErbB family of receptor tyrosine kinases. This family includes EGFR/ErbB1/HER1, ErbB2/HER2/Neu ErbB3/HER3, and ErbB4/HER4. For many years it was believed that EGFR plays a minor role in the development and progression of breast malignancies. However, recent findings have led investigators to revisit these beliefs. Here we will review these findings and propose roles that EGFR may play in breast malignancies. In particular, we will discuss the potential roles that EGFR may play in triple-negative tumors, resistance to endocrine therapies, maintenance of stem-like tumor cells, and bone metastasis. Thus, we will propose the contexts in which EGFR may be a therapeutic target.
Insights
Epidermal growth factor receptor (EGFR) may play significant roles in breast cancer progression, including in triple-negative tumors and metastasis. These findings suggest EGFR as a potential therapeutic target for breast malignancies.
Area of Science:
- Oncology
- Molecular Biology
- Cancer Research
Background:
- Epidermal growth factor receptor (EGFR) is part of the ErbB family of receptor tyrosine kinases.
- EGFR was previously thought to have a minor role in breast cancer development and progression.
- Recent research prompts a re-evaluation of EGFR's involvement in breast malignancies.
Purpose of the Study:
- To review recent findings on EGFR's role in breast cancer.
- To propose potential functions of EGFR in breast malignancies.
- To identify contexts where EGFR could be a therapeutic target.
Main Methods:
- Literature review of recent findings on EGFR in breast cancer.
- Analysis of potential EGFR roles in specific breast cancer contexts.
- Discussion of EGFR as a therapeutic target.
Main Results:
