Abstract:
The prognostic impact of minimal residual disease (MRD) has been demonstrated for several hematologic malignancies. While in acute lymphoblastic leukemias MRD assessment by polymerase chain reaction (PCR)-based methods has been established as an important tool for clinical risk assessment and is part of clinical management, data demonstrating a prognostic value of MRD in mantle cell lymphoma (MCL) were sparse and results from randomized trials have been published only recently. In the present review technical aspects of different MRD detection methods are discussed, as well as the prognostic relevance of MRD in the context of clinical trials in patients with MCL. Furthermore, recommendations are given for workflow and useful implication of MRD in future clinical trials design.
Insights
Minimal residual disease (MRD) monitoring shows prognostic value in hematologic cancers. Recent trials confirm its clinical importance for managing mantle cell lymphoma (MCL), guiding future treatment strategies.
Area of Science:
- Hematology
- Oncology
- Molecular Diagnostics
Background:
- Minimal residual disease (MRD) monitoring is crucial in hematologic malignancies.
