MRD is the term used to describe a small number of cancer cells remaining in patients following treatment, which are below the level of routine morphological detection1,2. Even when a patient is in remission it is possible for them to be ‘MRD positive’. The level of MRD can, theoretically, be used as a prognostic indicator to determine treatment efficacy and to detect cancer recurrence. MRD status is now increasingly measured as an endpoint in clinical trials for haematological malignancies, with the goal of treatment being MRD negativity. Indeed, the evidence suggests that in many haematological cancers, achieving MRD negativity in patients results in better clinical outcomes and is often an important psychological milestone for patients3-6.

The determination of MRD is made by detecting tumor-specific DNA, RNA or proteins, and is primarily performed using next-generation sequencing or multidimensional flow cytometry7-10. Owing to developments in MRD testing tools and technologies, MRD testing is increasingly being integrated into clinical practice outside of trials7,11,12. Therefore, although there are still questions remaining, it is important that clinicians understand when and how to use MRD testing for the optimal management of their patients.
