They represent a clinically relevant tumor model that allows researchers to stay one step ahead of the tumor in the clinic. This protocol establishes tumor organoids from fresh pancreatic tumor tissue samples and patient-derived xenografts of pancreatic adenocarcinoma origin. Cancer Research A Standardized Liquid Biopsy Preanalytical Protocol for Downstream Circulating-Free DNA Applications Julie Earl1, Silvia Calabuig-Fariñas1, María Eugenia Sarasquete1, Laura Muinelo Romay1, Sara Lopez-Tarruella1, Beatriz Bellosillo Paricio1, Marta Rodríguez1, Karmele Valencia Leoz1, Marta Dueñas Porto1, Noelia Tarazona1, Javier Hernandez Losa1, Rodrigo Almeida Toledo1 1The Liquid Biopsy and Biomarker Working Module, the Biomedical Research Network in Cancer (CIBERONC) The liquid biopsy has revolutionized our approach to oncology translational studies, with sample collection, quality, and storage being crucial steps for its successful clinical application. Here we describe a standardized and validated protocol for downstream circulating-free DNA applications that can be applied in most translational research laboratories.
