Several novel strategies have emerged in the last decade as potential therapies for patients with chemorefractory lymphoproliferative diseases and acute leukemia. While these treatments include exciting drugs that dramatically change the landscape of treatment, the organ-toxicity profile associated with these therapies may be significant. This article focuses on cardiac disorders associated with chimeric antigen receptor T-cell (CAR-T) therapy, as well as with novel regimens for acute leukemia.

Acute leukemia (AL) affects patients' well-being and inflicts substantial symptom burden. We evaluated palliative care needs and symptom burden in adult patients with AL from diagnosis through fourth week of induction chemotherapy. Newly diagnosed adult patients with AL scheduled for curative-intent treatments, prospectively completed Functional Assessment of Cancer Therapy-Leukemia questionnaire at diagnosis and postinduction therapy.

Stemness-associated cell states are linked to chemotherapy resistance in AML. We uncovered a direct mechanistic link between expression of the stem cell transcription factor GATA2 and drug resistance. The GATA-binding protein 2 (GATA2) plays a central role in blood stem cell generation and maintenance.

Donor cell leukemia (DCL), in which malignancy evolves from donor's stem cells, is an infrequent complication of allogeneic hematopoietic stem cell transplantation. Acute promyelocytic leukemia (APL) derived from donor cell is extremely rare and only four cases have been reported to date. Herein we report a case of donor cell-derived APL developing 32 months after haploidentical peripheral blood stem cell transplantation using posttransplant cyclophosphamide for myelodysplastic syndromes.

Surface antigen-directed immunotherapy is a curative treatment modality for acute myeloid leukemia (AML) that is characterized by the abundance and stability expression of surface antigens. However, current surface antigen-directed immunotherapies have shown poor outcomes and undesirable mortality rates in treating AML patients, primarily due to acquired resistance that arises from using single-target therapies to address the heterogeneous expression of surface antigens. Hence, in order to improve the efficacy of antigen-specific therapies for treating AML, we designed a bispecific aptamer-drug conjugate.

Leukemic stem cells (LSCs) fuel acute myeloid leukemia (AML) growth and relapse, but therapies tailored towards eradicating LSCs without harming normal hematopoietic stem cells (HSCs) are lacking. FLT3 is considered an important therapeutic target due to frequent mutation in AML and association with relapse. However, there has been limited clinical success with FLT3 drug targeting, suggesting either that FLT3 is not a vulnerability in LSC, or that more potent inhibition is required, a scenario where HSC toxicity could become limiting.
