AbstractThis study aims to explore the effect of the ITI (interferon alpha-1b, thalidomide, and interleukin-2) regimen on the AML1-ETO fusion gene in patients with t(8;21) acute myeloid leukemia (AML) who were in hematologic remission but positive for the AML1-ETO fusion gene. From September 2014 to November 2020; 20 patients with AML (15 from The Affiliated Cancer Hospital of Zhengzhou University, 4 from The First Affiliated Hospital; and College of Clinical Medicine of Henan University of Science and Technology, and 1 from Anyang District Hospital) with hematological remission but AML1-ETO fusion gene positivity were treated with different doses of the ITI regimen to monitor changes in AML1-ETO fusion gene levels. Twenty patients were treated with a routine dose of the ITI regimen, including 13 males and 7 females. The median patient age was 38 (14–70 years). The fusion gene was negative in 10 patients after 1 (0.5 ~ 8.6) month, significantly decreased in 4 patients after 2.8 (1 ~ 6) months, increased in 4 patients, and unchanged in 2 patients. The 4 patients with elevated levels of the fusion gene were treated with an increased dose of the ITI regimen, and all four patients became negative, for a total effective rate of 90%. The ITI regimen reduces AML1-ETO fusion gene levels in patients with AML who are in hematologic remission but are fusion gene–positive. Improvement was observed in patients’ response to a higher dose administration, and patients tolerated the treatment well.

Abstract IKZF1 belongs to the IKAROS family of transcription factors, and its deletion/mutation frequently affects acute lymphoblastic leukemia. In acute myeloid leukemia, IKZF1 deletion has been demonstrated recurrent, but whether IKZF1 mutation also exists in AML remained largely unknown. Herein, we analyzed the IKZF1 mutation in AML. In our cohort, the frequency of IKZF1 mutation was 2.6% (5/193), and 5 frameshift/nonsense mutations as well as 2 missense mutations were identified in total. Molecularly, IKZF1 mutation was absent in fusion gene-positive AML, but it was demonstrated as the significant concomitant genetic alteration with SF3B1 or bi-alleleCEBPA mutation in AML. Clinically, two IKZF1, PTPN11 and SF3B1-mutated AML patients exhibited one aggressive clinical course and showed primary resistant to chemotherapy. Furthermore, we confirmed the recurrent IKZF1 mutation in AML with cBioPortal tool from OHSU, TCGA and TARGET studies. Interestingly, OHSU study also showed that SF3B1 mutation was the significant concomitant genetic alteration with IKZF1 mutation, indicating their strong synergy in leukemogenesis. In conclusion, IKZF1 mutation recurrently affected AML.

Background: Hemophagocytic lymphohistiocytosis (HLH) is a rare aggressive syndrome of excessive immune activation. Clinical manifestations of this syndrome mimic various other clinical conditions making the diagnosis harder to achieve. These manifestations are believed to be a result of cytokine storm which leads, eventually, to a multi-organ failure and eventually death. The latter two might be prevented if HLH was diagnosed early. HLH is classified into primary consist of monogenic disorders and secondary occurs as a complication in various settings such as infection, autoimmune disease, and malignancy. In hematologic malignancies, HLH is classically associated with specific entities, mainly, lymphoma or induced by treatment-related infections. Acute myeloid leukemia, on the other hand, is less common trigger with only few case reports.   Case presentation: An 83-years-old, 5 years free of transitional cell man, presented with unstable atrial fibrillation was intubated and shortly after that he developed a multi-organ failure. Bicytopenia and a high level of ferritin aroused a clinical suspicion of HLH syndrome. Further evaluation revealed high levels of soluble interleukin 2 receptors and no activity of natural killers cells. A bone marrow was performed and it did not show phagocytosis, however, acute myeloid leukemia (AML) was diagnosed. AML was suggested to be associated with chemotherapy that our patient received 5 years earlier.   Conclusion: Hemophagocytic lymphohistiocytosis can be present as a multi-organ failure requiring a high index of suspicion. Chemotherapy related-AML can be a trigger for HLH.

Acute Myeloid

An 80-year-old Japanese male was treated with chemotherapy consisting of cyclophosphamide, doxorubicin, vincristine, and prednisolone, for non-Hodgkin lymphoma. Nine months after the chemotherapy, he was diagnosed with acute myeloid leukemia (AML) (M4) with translocation 8p11 and 22q13. The patient bone marrow indicated a remarkable degree of sea-blue histiocytosis. His disease was aggressive, and he died of the disease. Sea-blue histiocytes are macrophages harboring blue vacuoles and granular deposition, which results from the phagocytosis of dead cells and the subsequent deposition of phospholipids. AML with the t(8; 22) (p11; q13) translocation is a rare subtype of AML, which is a rare translocation with a prevalence of less than 1.0% among all AML cases. The oncogenesis of t(8; 22) (p11; q13) is caused by the fusion protein monocytic leukemia zinc finger protein (MOZ) and transcription factor p300. MOZ can be fused to various translocation targets including CBT, TIF2, and p300, corresponding to t(8; 16), inv(8), and t(8; 22), respectively. This subgroup of AML reveals the hallmarks of the disease, including monocytic arrest and erythro/hemophagocytosis by blasts. A substantial proportion of the AML M4/M5 subtype harboring MOZ as an aberrant fusion gene represents erythrophagocytosis. Although rare, t(8; 22) is very specific to the AML M4/M5 subtype and seems to represent sea-blue histiocytosis as one of the characteristic features of monocytic AML with macrophage activation. Thus, sea-blue histiocytes are considered to be one of hallmarks in monocytic AML with MOZ translocation.
