Emmanuel Antonarakis, MD, of the Masonic Cancer Center at the University of Minnesota, discusses his study presented at ASCO GU 2024 on the use of PARP1 mRNA expression as a prognostic biomarker of aggressive disease and a predictor of response to PARP inhibition for patients with castration-sensitive prostate cancer.
He elaborates on the differences between PARP1 mRNA expression and other biomarkers currently used for risk stratification in this patient population, as well as how it can be used in the clinical decision-making process for patients.
