SRP470036 PRJNA1035299 Analytical validation of K-4CARE: a comprehensive genomic profiling Comprehensive genomic profiling (CGP) has gradually gained acceptance in clinical practice to empower precision oncology in recent years. A single assay could provides a broad picture of genetic and genomic alterations in the tumor, which then aids physicians in disease diagnosis, prognosis and treatment selection. This study demonstrated an in-depth analytical validation of K-4CARE, a tumor CGP assay that integrates personalized circulating tumor DNA (ctDNA) tracking for residual cancer surveillance
