Fact checked by: Ashling Wahner

Dr Mouabbi highlights the ways that ctDNA has evolved from a research tool to a potential clinical decision-making aid in breast cancer.

Welcome to OncLive On Air®! I'm your host today, Ashling Wahner.

OncLive On Air is a podcast from OncLive®, which provides oncology professionals with the resources and information they need to provide the best patient care. In both digital and print formats, OncLive covers every angle of oncology practice, from new technology to treatment advances to important regulatory decisions.

In today’s episode, we had the pleasure of speaking with Jason Mouabbi, MD, about the role of circulating tumor DNA (ctDNA) testing in early-stage breast cancer management. Dr Mouabbi is an assistant professor in the Department of Breast Medical Oncology in the Division of Cancer Medicine at The University of Texas MD Anderson Cancer Center in Houston.

In our exclusive interview, Dr Mouabbi highlighted the ways that ctDNA has evolved from a research tool to a potential clinical decision-making aid in breast cancer, data suggesting that ctDNA negativity after neoadjuvant therapy can be more predictive of long-term outcomes than pathologic complete response, and the importance of offering ctDNA testing to patients and discussing the benefits of this emerging approach.
