In recent years the outcome of patients with multiple myeloma (MM) has significantly improved, due to new drugs. However, some agents, i.e. the alkylating drug melphalan, can be associated with an increased incidence of secondary malignancies. Myelodysplastic syndromes and acute myeloid leukemia are reported in the literature, and rarely acute lymphoblastic leukemia. Here we describe a unique case of a 56-years old female patient affected by MM since 2015 in complete remission after autologous stem cell transplant and in lenalidomide maintenance, who developed 2 years later mixed phenotype acute leukemia (MPAL). The patient, refractory to both lymphoblastic and myeloid acute leukemia regimens, achieved complete remission with bi-specific anti-CD19/anti-CD3 monoclonal antibody blinatumomab and with hypomethylating agent azacytidine plus the BCL-2 inhibitor venetoclax. She then underwent hematopoietic stem cell transplantation from HLA-identical sibling donor and she is still in complete remission after 9 months. To the best of our knowledge, there are no cases in the literature describing MPAL after autologous transplant for MM. Our patient was treated with blinatumomab and venetoclax and achieved complete remission 9 months from allogeneic transplant. The mechanism underlying the development of MPAL is not completely understood and therapies are still lacking. In this context the combination of blinatumomab, azacytidine and venetoclax successfully used in this patient may provide food for thought for further studies in this rare setting of patients.

Fludarabine, High-Dose Cytarabine and Idarubicin-Based Induction May Overcome the Negative Prognostic Impact of -ITD in Mutated AML, Irrespectively of -ITD Allelic Burden.

The mutations of and -ITD represent the most frequent genetic aberration in acute myeloid leukemia. Indeed, the presence of an mutation reduces the negative prognostic impact of -ITD in patients treated with conventional "3+7" induction. However, little information is available on their prognostic role with intensified regimens. Here, we investigated the efficacy of a fludarabine, high-dose cytarabine and idarubicin induction (FLAI) in 149 consecutive fit AML patients (median age 52) carrying the and/or -ITD mutation, treated from 2008 to 2018. One-hundred-and-twenty-nine patients achieved CR (86.6%). After a median follow up of 68 months, 3-year overall survival was 58.6%. Multivariate analysis disclosed that both mut ( < 0.05) and ELN 2017 risk score ( < 0.05) were significant predictors of survival. -mutated patients had a favorable outcome, with no significant differences between patients with or without concomitant -ITD ( = 0.372), irrespective of -ITD allelic burden. Moreover, in landmark analysis, performing allogeneic transplantation (HSCT) in first CR proved to be beneficial only in ELN 2017 high-risk patients. Our data indicate that FLAI exerts a strong anti-leukemic effect in younger AML patients with mut and question the role of HSCT in 1st CR in mut patients with concomitant -ITD.

Venetoclax in association with decitabine as effective bridge to transplant in a case of relapsed early T-cell lymphoblastic leukemia.

Clin Case Rep 2020 Oct 7;8(10):2000-2002. Epub 2020 Jul 7.

A case of an early-relapsed high-risk T-ALL with high BCL-2 expression on leukemic blasts was successfully treated with decitabine and venetoclax, achieving a CR. We suggest decitabine and venetoclax should be synergistic in BCL2-positive ALL.

Efficacy and safety of eltrombopag during conception and first trimester of pregnancy in a case of refractory severe immune thrombocytopenia.

Blood Coagul Fibrinolysis 2020 Sep;31(6):416-418

Hematology Unit, Azienda Ospedaliera Universitaria Senese e Università di Siena, Siena, Italy.

: Immune thrombocytopenia (ITP) is a relatively frequent cause of thrombocytopenia during pregnancy. Thrombopoietin receptor agonists (TPO-RAs) are the most recent drugs approved for second-line treatment of ITP. Limited data are available about their use in pregnancy with only a few published cases; yet no data exist about their effect when administered only during conception and first trimester of gestation. We describe the case of a woman with refractory ITP who took eltrombopag during conception and first trimester of pregnancy. No fetal or maternal complications were reported. Moreover, the patient remained in complete response after delivery despite therapy discontinuation. The analysis of this case and the revision of the available literature suggest that the use of TPO-RAs, thanks to their short time to response, may be effective and feasible during the first trimester of pregnancy, even if not yet recommended by current guidelines.

Flow Cytometry Assessment of CD26 Leukemic Stem Cells in Peripheral Blood: A Simple and Rapid New Diagnostic Tool for Chronic Myeloid Leukemia.

Cytometry B Clin Cytom 2019 07 3;96(4):294-299. Epub 2019 Feb 3.

Background: Recent investigations in chronic myeloid leukemia (CML) have focused on the identification and characterization of leukemic stem cells (LSCs). These cells reside within the CD34 /CD38 /Lin fraction and score positive for CD26 (dipeptidylpeptidase IV) a marker, expressed in both bone marrow (BM) and peripheral blood (PB) samples, that discriminates CML cells from normal hematopoietic stem cells (HSCs) or from LSCs of other myeloid neoplasms. CD26 evaluation could be a useful tool to improve the identification of CML LCSs by using flow-cytometry assay.

Methods: CD26 LSCs have been isolated from EDTA PB and BM samples of patients with leucocytosis suspected for CML. Analysis of LSCs CML has been performed by using custom-made lyophilized pre-titrated antibody mixture test and control tube and a CD45 /CD34 /CD38 /CD26 panel as a strict flow cytometric gating strategy.

Results: The expression of CD26 on CD34 /CD38 population was detectable in 211/211 PB and 84/84 BM samples of subsequently confirmed BCR-ABL CP-CML patients. None of the 32 samples suspicious for CML but scoring negative for circulating CD26 LSCs were diagnosed as CML after conventional cytogenetic and molecular testing. To validate our results, we checked for PB CD26 LSCs in patients affected by other hematological disorders and they all scored negative for CD26 expression.

Conclusions: We propose flow cytometry evaluation of CD26 expression on PB CD34 /CD38 population as a new rapid, reproducible, and powerful diagnostic tool for the diagnosis of CML. © 2019 The Authors.
