Recommendations for the assessment and management of measurable residual disease in adults with acute lymphoblastic leukemia: A consensus of North American experts The vast majority of adults with acute lymphoblastic leukemia (ALL) achieve remission with standard chemotherapy regimens, but many of these patients ultimately relapse and die from leukemia. In these patients, relapse occurs despite achievement of morphologic remission (ie, bone marrow blasts <5%), suggesting that low levels of measurable residual disease (MRD), also called “minimal residual disease,” persist in the remission bone marrow (Figure 1). Compared with morphologic assessment alone, sensitive methods of MRD quantification can better estimate the reduction in posttreatment disease burden and provide information about the leukemia biology and treatment response of individual patients. Posttreatment MRD status […]
