Implementation of Liquid Biopsies During Routine Clinical Care in Patients With Advanced Malignancies (LIQPLAT)

The goal of this study is to assess the implementation and feasibility of ctDNA measurements from blood samples obtained during routine clinical care of cancer patients in the University Hospital Basel. Researchers will compare clinical and patient reported outcomes from the LIQPLAT study with patients who did not receive ctDNA measurements (external comparator from registry AO\_2023-00091). Blood samples will be drawn from the patients as part of routine care and ctDNA measurements will be performed on these samples.
