Re-biopsy what biomarkers to test for
 

Hello everyone,

My wife will have biopsy soon. Beside ER, PR, and Her2, what other bio markers that guide treatment selection should we ask the oncologist to test for?

Thank you very much,

Nguyen

Perhaps you can get the nurse practitioner/navigator to locate a copy of the article and discuss it with your wife's doctor ...

Abstract

Breast cancer is the most commonly diagnosed cancer and the second leading cause of cancer death among women in the United States. Recently, interest has grown in the role of epigenetics in breast cancer development and progression. Epigenetic changes such as DNA methylation, histone modifications, and abnormal expression of non-coding RNAs emerged as novel biomarkers in breast cancer diagnosis, therapy, and prevention. This review focuses on the most recent mechanistic findings underlying epigenetic changes in breast cancer development and their role as predictors of breast cancer risk. The rapid progress in our understanding of epigenetic findings in breast cancer has opened new avenues for potential therapeutic approaches via identification of epigenetic targets. We highlight the development of novel epigenetically targeted drugs, relevant clinical trials in breast cancer patients, and recent approaches combining epigenetic agents with chemotherapy and/or endocrine therapy that may incrementally improve long-term outcomes in appropriately selected breast cancer patients. Biomarkers of response are needed, however, to identify patient subsets that are most likely to benefit from epigenetic treatment strategies.

Lots of information in below articles, but nothing definitive beside ER, PR, and Her2.

Thank you both. Jackie that is the odd thing was that I recurred after 5 years. I know it happens but I needed to check before I make peace with rads to the super clavicle.
