SarcBOP - An interdisciplinary and translational registry SarcBOP aims to establish a database that integrates every aspect possibly relevant to sarcoma treatment and research. SarcBOP thus will not be limited to specific questions or patient groups, but instead will build a comprehensive database including clinical, pathologic, and radiologic information, multi-layered molecular data, and patient-reported outcomes, combined with a dedicated biobank for tissue samples and liquid biopsies. As the study integrates seamlessly with the clinical activities of the Heidelberg Sarcoma Center, the Molecular Diagnostics Program of NCT Heidelberg, including the NCT/DKTK MASTER Program, and with the NCT Trial Center, including the PMO Clinical Trials Program, SarcBOP will generate a comprehensive and continuously growing resource for clinicians, researchers, and, finally, patients.
