The FDA approved Xospata (gilteritinib) tablets for the treatment of adult patients who have relapsed or refractory acute myeloid leukemia (AML) with a FLT3 mutation as detected by an FDA-approved test.

We reported the case of a patient from the city of Viña del Mar, Chile, a carrier of acute myeloid leukemia in whom an infection by Lophomonas sp. was confirmed by bronchoalveolar lavage. She was treated with antibiotics but died of complications of the underlying disease. There is little literature available on this microorganism. We conclude that Lophomonas sp. should be considered as a diagnostic possibility if protozoa are found in bronchoalveolar lavage of immunosuppressed patients.

Conclusion: Our data indicate that NPMc+ leukemic cell survival requires upregulation of PBX3 and HOXA9, and this action can be largely attenuated by a DOT1L inhibitor.

Haznedaroglu, Nilgun Sayınalp, Osman Ozcebe, Umit Yavuz Malkan, Hakan GokerAbstractBackground and AimThe refractory acute myeloid leukemia (AML) includes patients who fail standard induction chemotherapy, relapse within 6 months after first complete remission and relapse twice or more. The outcome of these patients is usually very poor with only a small proportion could be rescued by allogenic hematopoietic stem cell transplan…

ConclusionsOur findings demonstrated that SOX7 methylation conferred adverse prognosis in MDS patients and was associated with leukemia progression.

The CD33-targeting bispecific T-cell engager (BiTE) AMG 330 proved to be highly efficient in mediating cytolysis of acute myeloid leukemia (AML) cells in vitro and in mouse models. Yet, T-cell activation is correlated with upregulation of programmed cell death-ligand 1 (PD-L1) and other inhibitory checkpoints on AML cells that confer adaptive immune resistance. PD-1 and PD-L1 blocking agents may counteract T-cell dysfunction, however, at the expense of broadly distributed immune-related adverse events (irAEs). We developed a bifunctional checkpoint inhibitory T cell–engaging (CiTE) antibody that combines T-cell redir…

Abstract
Lim SH, Nam HN, Lim KI, Jeon IS. A case of myeloid sarcoma presenting with an orbital mass, hearing loss, and multiple cranial neuropathies. Turk J Pediatr 2018; 60: 322-325. Primary myeloid sarcoma occurring in multiple sites; orbit, ear, brain, and spinal cord is a rare clinical entity. A 15-year-old male adolescent presented with bilateral orbital mass, hearing difficulty, and clinical signs of multiple cranial nerves palsy. Approximately 6 weeks later, acute myeloid leukemia was confirmed. This case alerts us that in patients with diverse sarcomatous lesions, acute myeloid leukemia presenting as myelo…

Conclusion: CLAG was effective and well tolerated for R/R AML. BM blasts ≥42.1%, age ≥60 years, high risk stratification, and second or higher salvage therapy were independent factors for a poor prognosis.Acta Haematol 2019;141:43 –53

In this study we explored whether microvessel density, a biomarker of angiogenesis, might be relevant in MS. We studied 60 MS, 24 acute myeloid leukemia, 5 normal bone marrow samples and 2 cases of extramedullary hemopoiesis in patients without evidence of hematological malignancy. We used immunohistochemistry (anti-CD34) to identify and quantify micro-vessel density (MVD) and micro-vessel grading (MVG). We found that MS had significantly higher MVD and MVG than normal bone marrow (p = 0.0002 and p

This study aimed to evaluate the significance of dynamic MRD pretransplantation on outcome of AML patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Methods: We retrospectively analyzed 145 consecutive AML patients undergoing allo-HSCT in complete remission status between June 2013 and June 2016. MRD was determined with multiparameter flow cytometry after the first and second courses of chemotherapy and pre-HSCT.
Results: In matched sibling donor transplantation (MSDT) settings, patients with positive MRD had higher cumulative incidence of relapse (CIR) than those without MRD after…
