Ep. 271 How Biomarkers Enhance Precision Medicine in Non-Muscle Invasive Bladder Cancer with Dr. Katie Murray and Dr. Sarah Psutka

As new genetic and AI-powered tools emerge for bladder cancer screening, are we getting closer to reducing the need for invasive cystoscopies? In part five of the 2025 BackTable NMIBC Creator Weekend™ series, host Dr. Vignesh Packiam engages in an insightful discussion with Dr. Sarah Psutka from the University of Washington and Dr. Katie Murray from NYU about the complexities and potential benefits of using biomarkers in non-muscle invasive bladder cancer (NMIBC).

SYNPOSIS

The conversation covers the current challenges of interpreting positive biomarkers without clinical correlates, the gold standard of biopsies, and the potential of various biomarkers such as urine cytology, FISH, and newer genomic tests like the Decipher Bladder Genomic Classifier. They also touch upon the role of AI in pathology, the cost implications of biomarkers, and how these tools might influence future clinical practices and patient decisions. The episode emphasizes the need for precision medicine, careful patient counseling, and the impact of false positives and negatives on both patients and healthcare providers.
