Molecular disease monitoring in translocation positive tumors

Molecular disease monitoring in translocation positive tumors

The EFACT study (EWS-FLI sequence analysis in circulating tumor DNA) investigates the clinical utility of circulating tumor DNA as a plasma tumor marker in Ewing sarcoma patients.
The LiBSTiC study (Liquid Biopsies of Solid Tumors in Children) includes children and adolescents with translocation positive sarcomas and Non-Hodgkin-Lymphoma.
Quantification of circulating tumor DNA allows control of therapy response on a molecular level and aims to improve individual therapy optimization.
