Schematic overview of definition of lead-time in the curative (a) and palliative (b) setting. Clinical lead-time can be defined as the time between blood-based detected and clinical-detected recurrence/progression. The biological lead-time can only be defined if scans and blood samples are done at the same time. MRD, minimal residual disease; SOC, standard of care.
