I would just add that I would not want to be denied treatment with EGFR antibody therapy because of being EGFR negative. Treatment options for triple negative breast cancer (TNBC) are generally limited to cytotoxic chemotherapy.

Although the activity of the epidermal growth factor receptor (EGFR) pathway is increased in triple-negative breast cancers (TNBC), patients are generally insensitive to EGFR inhibitors. 38 We analysed the expression of EGFR in several breast cancer cell lines by immunoblotting and found that EGFR was notably overexpressed in TNBC cells (MDAâMBâ231, MDAâMBâ468, HS578T and HCC1860) compared to human breast â¦ Triple-negative breast cancer (sometimes abbreviated TNBC) is any breast cancer that does not express the genes for estrogen receptor (ER), progesterone receptor (PR) and HER2/neu. Introduction. By testing several breast cancer cell lines, we demonstrated that Snai2 downregulation prevents cell motility and that its expression is promoted by cIAP1. Shen et al., 2019, Cancer Cell 35, 64â80 January â¦ found that this is because TNBC cells produced the prosurvival protein Mcl-1.

Benbrahim Z, Antonia T, Mellas N. EGFR mutation frequency in Middle East and African non-small cell lung cancer patients: a systematic review and meta-analysis. Since EGFR is known to be in a crosstalk with Notch signaling in different tumor entities including triple negative breast cancer [53, 54], we examined the effect of GSI on expression of EGFR transcript levels in control and Syndecan-1-depleted SUM-149 cells. Younger patients or African-American women are most vulnerable to TNBC. 1. The overexpression or mutation of EGFR is associated with the development of various types of cancers, such as breast cancer, lung cancer, glioblastoma, and colorectal cancer. Triple-negative breast (TNBC) cancer that is upregulated with epidermal growth factor receptor (EGFR), and devoid of both the hormonal receptors and epidermal growth factor receptor 2 (HER 2), has led to a concept of treating TNBC with EGFR-targeted therapeutics.

Recently, anti-epidermal growth factor receptor (EGFR) therapy has been introduced for TNBC patients.

Triple-negative breast cancers are a poor prognostic group of breast cancers that donât respond to conventional hormonal and her2neu targeted therapy. Triple-negative breast cancer is strongly associated with EGFR, CK5/6 and/or c-KIT expression Based on the available clinical data, tissue samples from a total of 36 patients were reviewed and retrieved for EGFR, CK5/6 and c-KIT staining. 1 TNBC lacks estrogen receptor (ER) and progesterone receptor (PR) overexpression and human epidermal growth â¦ Despite initial good response to chemotherapy, 30% of the patients relapse within 5 years after treatment. Overexpression of EGFR was observed in 15â30% of breast carcinomas and was associated with large tumor size and poor clinical outcomes. In breast cancer, FSCN1 expression is associated with hormone receptor-negative, more aggressive clinical course, and also associated with TNBC in African American and Chinese women 11,12,13. In this short review of the literature, I will try to answer if there is an indication for EGFR inhibitors in the metastatic triple negative breast cancer. BMC Cancer. 1 At least 20% of breast cancers are characterized by triple-negative receptor status (negative for estrogen receptor [ER], progesterone receptor [PR], and HER2).

EGFR overexpression is a common marker in TNBC, and its expression has been correlated with poor outcome. 14071 Background: Triple-negative BrCa lacks expression of hormone receptors and HER-2 but does express EGFR. Breast tumors lacking expression of human epidermal growth factor receptor 2 (HER2) and the estrogen and the progesterone receptors (triple negative; TNBC) are more aggressive than other disease subtypes, and no molecular targeted agents are currently available for their treatment. Using single-cell RNA sequencing in conjunction with functional assays, they identify TNBC tumors in which EGFR expression identiï¬es cells with tumor-initiating capacity whose proliferative expansion is sensitive to EGFR inhibition.
