Shorter duration of Blinatumomab administration to 14 days has same efficacy and safety profile in treatment of relapsed/refractory B-cell precursor acute lymphoblastic leukemia: A retrospective single-center study
Kong J, Miao W, Lu J, Liu Y, Kong X, Qiu H and Song B
Treatment of patients with relapsed/refractory B-cell precursor acute lymphoblastic leukemia (r/r BCP-ALL) remains a significant clinical challenge. Many new strategies are changing the treatment landscape of r/r BCP-ALL in recent years. Blinatumomab has improved outcomes in r/r BCP-ALL, though high treatment costs and extended hospital stays are significant concerns. We considered that shortening the duration of blinatumomab administration during induction therapy might solve these problems.

Lebel E, Vainstein V, Milani P, Palladini G, Shragai T, Lavi N, Magen H, Assayag M, Avivi I and Gatt ME
Treatment for relapsed/refractory AL amyloidosis (AL) is an unmet need. The safety and efficacy of belantamab mafodotin (BLM) in multiple myeloma are known, whereas in AL data are limited.
Sudden Blast Crisis in a Chronic Myeloid Leukemia Patient in Treatment-Free Remission: A Case Report and Literature Review
Liang Q, Liu Z, Wu Y, Zhu H and Yang Y
Treatment-free remission (TFR) has emerged as a new goal in the treatment of chronic myeloid leukemia (CML). TFR is considered a safe intervention because patients who experienced molecular relapse usually responded well to tyrosine kinase inhibitors resumption and regained molecular response quite efficiently. Nevertheless, there have been reports of occurrence of blast crisis during TFR.
Real-World Use of Ruxolitinib in Patients with Myelofibrosis and Anemia or Thrombocytopenia at Diagnosis
Yu J, Bland E, Schuler T, Cordaro T and Braunstein E
Ruxolitinib is approved for treatment of myelofibrosis. We evaluated ruxolitinib in patients with anemia (hemoglobin <10 g/dL) or thrombocytopenia (platelet count ≤100 × 109/L) at diagnosis.
Efficacy of Haploidentical Allogeneic Hematopoietic Cell Transplantation following Two Courses of Venetoclax and Azacytidine Therapy in Patients over 55 Years Old with Acute Myelogenous Leukemia
Cao J, Zhuang X, Luo D, Pei R, Lu Y, Chen D, Li S, Du X and Liu X
The combination of venetoclax (VEN) and azacytidine (AZA) has demonstrated potential in achieving rapid and effective remissions in elderly patients with acute myeloid leukemia (AML). Allogeneic hematopoietic stem cell transplantation is a promising potential cure for high-risk AML, as VEN-based therapies have a worse prognosis in elderly patients. This study aimed to assess the efficacy of sequential haploidentical HSCT following two courses of VEN and AZA therapy in patients with AML aged 55 years and older.
Thiamine-Responsive Megaloblastic Anemia Syndrome Mimicking Myelodysplastic Neoplasm
Klötzer C, Schnabel F, Kubasch AS, Jentzsch M, Franke GN, Uhlig J, Faust H, Jauss RT, Oppermann H, Popp D, Metzeler KH, Lemke JR, Vučinić V and Platzbecker U
Thiamine-responsive megaloblastic anemia syndrome (TRMA) is a rare autosomal recessive disease with a homozygous or compound-heterozygous mutation in the SLC19A2 gene characterized by megaloblastic anemia, diabetes mellitus (DM), and sensorineural hearing loss with onset in childhood. Folic acid and vitamin B12 in serum are normal with dysplastic erythropoiesis in the bone marrow often mimicking myelodysplastic neoplasms (MDS) as a potential differential diagnosis. Thiamine substitution leads to normalization of anemia, without effects on hearing loss or DM.
Role of Autologous Transplant in Newly Diagnosed Multiple Myeloma Patients Treated with Novel Triplets: A Systematic Review and Meta-Analysis
Amitai I, Gurion R, Raanani P, Vaxman I, Yeshurun M, Magen H, Gafter-Gvili A and Shargian L
High-dose therapy with melphalan followed by autologous stem cell transplant in the upfront setting (upfront ASCT) has significantly improved clinical outcomes of myeloma patients and become the standard of care for the past 30 years. However, with the advent of modern induction therapy, the role of upfront ASCT approach has been called into question. Several prospective studies have examined whether continuing with triplet therapy as consolidation with optional ASCT at relapse (triplet-alone) could result in comparable outcomes.
Bosutinib Treatment of Chronic Myeloid Leukemia in Lombardy
Iurlo A, Bucelli C, Intermesoli T, Elena C, D'Adda M, Agostani E, Fiamenghi C, Maffioli M, Orofino N, Lunghi F, Gardellini A, Carraro MC, Inzoli A, Gigli F, Palazzolo R, Bertolli V, Cattaneo D, Pungolino EM and Gambacorti-Passerini C
Up to 30% of CML patients will require a therapeutic change during follow-up due to intolerance and/or resistance to first-line tyrosine kinase inhibitor (TKI) approach. In this context, bosutinib (BOS) has not only demonstrated its efficacy, but also presents a favorable safety profile, without comorbid conditions representing an absolute contraindication to its use.
Intake of Proton Pump Inhibitors Is Associated with a Shorter Time to First Treatment in Early-Stage Chronic Lymphocytic Leukemia
Tadmor T, Melamed G, Alapi H, Gazit S, Patalon T and Rokach L
Proton pump inhibitors (PPIs) are one of the most widely used drugs worldwide [Gut Liver. 2017;11(1):27-37]. The use of PPI has become a common practice and is overprescribed for all patients with cancer including patients with hematological malignancies. In the current study, we aimed to explore retrospectively the effect of PPI, on time to first treatment (TTFT) in a large cohort of patients with chronic lymphocytic leukemia (CLL) who were under watch-and-wait approach.
Outcomes of Fedratinib in Routine Treatment of Ruxolitinib-Resistant or -Refractory Patients with Primary and Post-Polycythemia Vera or Essential Thrombocythemia Myelofibrosis: A Nationwide Retrospective Study
Duek A, Tzinman A, Maziuk K, Levy A, Ellis M, Stemer G, Shacham Abulafia A, Cohen A, Lavi N, Ronson A, Braester A, Shapira S, Canaani J, Volchek Y, Leiba R and Leiba M
In recent years, fedratinib, a selective JAK2 inhibitor, has emerged as a potential therapeutic option for patients who have failed or are intolerant to ruxolitinib. Despite the promising results observed in clinical studies, real-world evidence from the USA and Europe suggests that the efficacy of fedratinib may be less conclusive. We report the characteristics, treatment patterns, and clinical outcomes of patients with myelofibrosis (MF) treated with fedratinib following ruxolitinib failure in Israel's clinical practice.

Geng M and Sun Z
The nutritional status of patients undergoing hematopoietic stem cell transplantation (HSCT) is critically important. This study aimed to assess the impact of comprehensive nutritional interventions on the well-being of individuals with hematological diseases who underwent HSCT.

Outcomes of Patients with Myeloid Malignancies and Cardiovascular Disease Undergoing Allogeneic Stem Cell Transplantation
Sanchez-Petitto G, Goloubeva O, Childress J, Iqbal T, Masur J, An M, Muhammad S, Lawson J, Li G, Barr B, Emadi A, Duong VH, Hardy NM, Rapoport AP, Baer MR, Niyongere S and Yared JA
Reduced-intensity conditioning (RIC) and nonmyeloablative (NMA) regimens have enabled patients with cardiovascular disease (CVD) to undergo allogeneic stem cell transplantation (allo-HSCT). However, little is known about long-term outcomes, including cardiovascular (CV) complications.
Prognostic Value of the Pretransplant Fibrosis-4 Index on Non-Relapse and Overall Mortality following Unrelated Single-Unit Cord Blood Transplantation in Adults
Konuma T, Monna-Oiwa M, Kato S, Isobe M, Takahashi S and Nannya Y
The fibrosis-4 (FIB-4) index is a noninvasive marker of liver fibrosis. The FIB-4 index predicts poor outcomes in patients with hepatic and non-hepatic diseases. However, the association of the FIB-4 index with mortality and liver-related clinical outcomes following cord blood transplantation (CBT) is unclear.
Real-World Impact of Routine Addition of Antithymocyte Globulin to Standard GVHD Prophylaxis in Myeloablative Unrelated Donor Transplants: Important Gains in Graft-versus-Host Disease Prevention though No Difference in Overall Survival
Bai N, Limvorapitak W, Henderson R, Abou Mourad Y, Chung S, Forrest D, Hay K, Kuchenbauer F, Nantel S, Narayanan S, Nevill T, Power M, Rodrigo J, Roy C, Sanford D, Song K, Stubbins R, Sutherland H, Toze C and White J
Antithymocyte globulin (ATG) has been demonstrated to reduce the incidence of graft-versus-host disease (GVHD); however, it remains controversial whether these gains are offset by an increase in relapse.

Hu Q, Yang Y, Yang C, Chen M and Han B
Aplastic anemia (AA) is characterized by bone marrow failure and cytopenia. Eltrombopag (ELT) is effective and safe for treating refractory/relapsed AA; however, reports on the long-term outcomes of transfusion-dependent non-severe AA (TD-NSAA) are limited.
