Immunotherapies targeting CD19 (blinatumomab) and CD22 (inotuzumab ozogamicin) have demonstrated higher complete response rates and improved survival compared with chemotherapy in relapsed/refractory acute lymphoblastic leukemia (ALL), and are now standard of care in the relapsed setting. However, most adult patients still die of ALL despite these therapies, with or without hematopoietic stem cell transplant. At the NCCN 2019 Annual Congress: Hematologic Malignancies, Dr. Jae Park summarized clinical data from key trials of novel immunotherapies in ALL and reviewed evidence-based treatment approaches for adults with relapsed/refractory B‐cell ALL.

The prognosis for patients with newly diagnosed acute lymphoblastic leukemia (ALL) has improved with the use of more intensive chemotherapy regimens, tyrosine kinase inhibitors, targeted agents, and allogeneic hematopoietic cell transplantation. However, the management of relapsed or refractory (R/R) ALL remains challenging and prognosis is poor. The NCCN Guidelines for ALL provide recommendations on standard treatment approaches based on current evidence. These NCCN Guidelines Insights summarize treatment recommendations for R/R ALL and highlight important updates, and provide a summary of the panel's discussion and underlying data supporting the most recent recommendations for R/R ALL management.

Survival outcomes for older adults with acute lymphoblastic leukemia (ALL) are poor and optimal management is challenging due to higher-risk leukemia genetics, comorbidities, and lower tolerance to intensive therapy. A critical understanding of these factors guides the selection of frontline therapies and subsequent treatment strategies. In addition, there have been recent developments in minimal/measurable residual disease (MRD) testing and blinatumomab use in the context of MRD-positive disease after therapy. These NCCN Guidelines Insights discuss recent updates to the NCCN Guidelines for ALL regarding upfront therapy in older adults and MRD monitoring/testing in response to ALL treatment.
