OncClub | <b>Early Identification of TP53 Mutations Via IHC in AML and MDS</b>

Drs Gerber and Patel discuss a study they conducted investigating the use of IHC as a biomarker for early TP53 mutation identification in MDS and AML.

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 OncClub episode, we had the pleasure of speaking with Jonathan M. Gerber, MD; and Shyam A. Patel, MD, PhD, about a study they conducted investigating the use of immunohistochemistry (IHC) as a biomarker for early TP53 mutation identification in patients with myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML). Dr Gerber is a member of the faculty in the Department of Medicine at New York University (NYU) Grossman School of Medicine; as well as the chief clinical officer of the NYU Perlmutter Cancer Center. Dr Patel is an associate professor at the University of Massachusetts Chan Medical School; as well as a hematologist and oncologist at the UMass Memorial Medical Center in Worcester.

In our exclusive interview, Drs Gerber and Patel discussed the evaluation of p53 IHC as a surrogate biomarker for TP53-mutant MDS and AML. They shared how the presence of TP53 mutations in these diseases significantly worsens prognosis, necessitating urgent treatment. They also highlighted how IHC results are available within 48 to 72 hours. Gerber and Patel explained this study's design and patient population, as well as how IHC's inverse correlation with overall survival highlights its potential as an early biomarker, though it has lower sensitivity for certain mutations.
