Liquid biopsy in genitourinary cancers: circulating tumor DNA as a predictive biomarker for treatment selection and resistance monitoring

Background: Genitourinary (GU) cancers—prostate, urothelial, and renal cell carcinomas (RCCs)—are a leading source of oncologic morbidity and mortality. Tumor heterogeneity and evolving resistance limit static tissue biopsies, requiring real-time, non-invasive biomarkers. Circula...
