Routine Prophylaxis with Levetiracetam offers no benefit in CD19 CAR-T for LBCL: a Multicenter Propensity-matched Study.

This study aims to evaluate the impact of levetiracetam (LVT) prophylaxis on the incidence and severity of Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) in patients undergoing anti-CD19 CAR-T therapy for large B-cell lymphoma (LBCL). A propensity score-matched cohort of 254 patients was analyzed, comparing those receiving LVT prophylaxis with those not receiving it in a 1:1 ratio. The results showed no significant difference in the occurrence of ICANS of any grade between the two groups (32.

Predicting thrombotic risk in patients with classical Hodgkin lymphoma: Thro-HL multicenter study.

Thrombosis Lymphoma (ThroLy) and Khorana scores have been conceived to predict the thrombotic risk in oncohematologic patients. Currently, there is no univocal indication to perform thromboprophylaxis in classical Hodgkin lymphoma (cHL). We performed a retrospective study to validate scores and risk factors in a cohort of consecutive patients with cHL, treated from 2014 to 2022 outside clinical trials.

Treatment Free Remission (TFR) in Chronic Phase-Chronic Myeloid Leukemia (CP-CML): Analysis of Predictive Factors and Novel Baseline Scoring System to Predict Molecular Relapse.

Background: Treatment free remission (TFR) is a key treatment goal in chronic-phase chronic myeloid leukemia (CP-CML) patients with sustained deep molecular response (DMR). While clinical trials report that approximately 40%-50% of such patients can discontinue tyrosine kinase inhibitors (TKIs) without presenting a molecular relapse (MRec), real-world data remain limited. Optimizing patient selection before TKI discontinuation is crucial for CML management and resource allocation.

CD99 expression in acute myeloid leukemia with FLT3 internal tandem duplications (FLT3-ITD-AML): a flow-cytometric marker for an accurate diagnostic workup.

Internal tandem duplications of FLT3 (FLT3-ITD) in acute myeloid leukemia (AML) are associated with poor outcomes. CD99 is frequently overexpressed in AML and emerged as potential diagnostic marker. Ninety consecutive newly diagnosed AML patients were retrospectively analyzed.

Dosing and clinical outcomes of ruxolitinib in patients with myelofibrosis in a real-world setting: Interim results of the Italian observational study (ROMEI).

Background: Myelofibrosis (MF) significantly impacts patients' overall survival (OS) and quality of life (QOL). This prospective study analyzed ruxolitinib dosing patterns and associated clinical outcomes in patients with MF over 12 months.

Methods: ROMEI, a multicenter, observational, ongoing study, enrolled 508 adult patients with MF treated with ruxolitinib.

T-cell Receptor (TCR)-Vβ Repertoire Flow Cytometry for T-cell Lymphoproliferative Disorder: a Retrospective Analysis of a Single-Center Real-Life Laboratory Experience.

Background: Discrimination between clonal and reactive cell proliferation is critical for the correct management of T-cell lymphocytosis. Multiparametric flow cytometry (MFC) represents a valuable tool, particularly because it allows the evaluation of the T-cell receptor (TCR) Vβ repertoire to pinpoint eventual clonality in T-cell lymphocytosis. A restricted expansion of a single out of the 24 evaluable families or a "clonogram-off" pattern is highly suggestive of the presence of a clonal T-cell population.

Primary mediastinal large B-cell Lymphoma: Biological features, clinical characteristics and current treatment strategies.

Primary mediastinal large B-cell lymphoma (PMBCL) is a distinct subtype of B-cell lymphoma, representing a clinical and therapeutic challenge due to its unique presentation, histopathological features, and treatment response. It primarily affects young adults, with a significant female preponderance, and is characterized by a large anterior mediastinal mass that causes compressive symptoms. Despite its aggressive nature, PMBCL patients have a favorable prognosis, with a 5-year survival rate exceeding 80% when early remission is achieved through first-line therapy.

Long-Term Survival with Multiple Myeloma: An Italian Experience.

Background/objectives: Treatments for multiple myeloma (MM) have expanded in the last decade, and the overall survival (OS) of MM patients (pts) is in continuous improvement. With the availability of new treatments and the use of high-dose chemotherapy, followed by autologous hematopoietic stem cell transplantation (ASCT), the median OS of newly diagnosed MM (NDMM) pts is 6-8 years. To date, approximately 50% and 28% of MM patients are still alive at 5 years and 10 years.

Neoadjuvant Immunotherapy and De-escalation of Surgery in Locally Advanced Breast Implant-associated Anaplastic Large Cell Lymphoma.

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare form of non-Hodgkin T-cell lymphoma diagnosed in patients with a history of breast implants. Most patients develop a periprosthetic effusion at early stages of disease while less common presentations include a palpable mass, severe capsular contracture, lymphadenopathy, or cutaneous erythema. Due to the complex nature of this disease, a multidisciplinary approach is necessary for optimal management, particularly in locally advanced disease or inoperable patients.

Integration of CD200, CD43 and ROR1 in Multiparameter Flow Cytometry (MFC) Routine Panels for the Differential Diagnosis of B-cell lymphoproliferative Disorders (B-LPDs).

Background: Clonal mature B-cell lymphoproliferative disorders (B-LPDs) are a heterogeneous group of neoplasia characterized by the proliferation of mature B lymphocytes in the peripheral blood, bone marrow and/or lymphoid tissues. B-LPDs classification into different subtypes and their diagnosis is based on a multiparametric approach. However, accurate diagnosis may be challenging, especially in cases of ambiguous interpretation.

Molecular clustering on ctDNA improves the prognostic stratification of patients with DLBCL compared with ctDNA levels.

Circulating tumor DNA (ctDNA) levels can help predict outcomes in diffuse large B-cell lymphoma (DLBCL), but its integration with DLBCL molecular clusters remains unexplored. Using the LymphGen tool in 77 DLBCL cases with both ctDNA and tissue biopsy, a 95.8% concordance rate in molecular cluster assignment was observed, showing the reproducibility of molecular clustering on ctDNA.

Red Blood Cell Distribution Width May Predict Drug-Induced Anemia and Prognosis in Patients Affected by Primary/Secondary Myelofibrosis Treated with Ruxolitinib.

Introduction: Myelofibrosis (MF) is often characterized by a multifactorial anemia determined, in part, by bone marrow (BM) fibrosis, extramedullary erythropoiesis and splenomegaly. Ruxolitinib (RUX) is the first-in-class janus kinase 2 (JAK2) inhibitor approved for treatment of MF, proved to reduce spleen volume and decrease symptom burden. The red cell distribution width (RDW) is the measure of erythrocyte volume variability (anisocytosis).

PET-Based Risk Stratification in Primary Mediastinal B-Cell Lymphoma: A Comparative Analysis of Different Segmentation Methods in the IELSG37 Trial Patient Cohort.

Standardizing tumor measurement on F-FDG PET is crucial for the routine clinical use of powerful PET-derived lymphoma prognostic factors such as metabolic tumor volume (MTV) and total lesion glycolysis (TLG). The recent proposal of an SUV of 4 as a new reference segmentation threshold for most aggressive lymphomas may homogenize volume-based metrics and facilitate their clinical application. This study compared MTV and TLG in primary mediastinal B-cell lymphoma (PMBCL) patients estimated using an SUV of 4 and the current threshold at 25% of SUV Baseline PET metrics were evaluated in 501 PMBCL patients from the IELSG37 trial.

Molecular measurable residual disease by immunoglobulin gene rearrangements on circulating tumor DNA predicts outcome in diffuse large B-cell lymphoma.

In diffuse large B-cell lymphoma (DLBCL) treatment response relies on imaging. We investigated the potential value of molecular measurable residual disease (MRD) on circulating tumor DNA (ctDNA) to predict the outcome of 73 DLBCL patients. At baseline, next-generation sequencing was used to detect clonal immunoglobulin (IG) gene rearrangements on tumor biopsies (N=57) and ctDNA (N=73).

Understanding and overcoming resistance to tyrosine kinase inhibitors (TKIs) in Chronic myeloid leukemia (CML).

Introduction: Chronic myeloid leukemia (CML) represents one of the first neoplasms whose molecular pathogenesis was successfully unraveled, with tyrosine kinase inhibitors (TKIs) representing one of the first-targeted therapies. TKIs have revolutionized long-term outcomes of CML patients and their life expectancy. Nonetheless, a minority of patients will develop TKI resistance due to a complex and multifactorial process that ultimately leads to the emergence of an unresponsive cancer clone.

Clinical and biological advances of critical complications in acute myeloid leukemia.

Managing acute myeloid leukemia (AML) and its critical complications requires understanding the complex interplay between disease biology, treatment strategies, and patient characteristics. Complications like sepsis, acute respiratory failure (ARF), hyperleukocytosis, coagulopathy, tumor lysis syndrome (TLS) and central nervous system (CNS) involvement present unique challenges needing precise evaluation and tailored interventions. Venetoclax-induced TLS and differentiation syndrome (DS) from IDH1/IDH2 or menin inhibitors highlight the need for ongoing research and innovative approaches.

Different prognosis according to treatment in patients with acute promyelocytic leukemia: How the outcome changed over time.

A comprehensive analysis of 220 patients diagnosed with APL between 1993 and 2022 is here reported. Overall, 214 patients (97.2%) received induction therapy.

Response Rates and Transplantation Impact in Patients with Relapsed Acute Promyelocytic Leukemia.

Background: The introduction of all- retinoic acid (ATRA) and arsenic trioxide (ATO) has radically improved the prognosis of acute promyelocytic leukemia (APL), with cure rates above 80%. While relapse occurs in less than 20% of cases, addressing this issue remains challenging. Identifying effective salvage therapies for relapsed APL is crucial to improve patient outcomes.

CD146 Molecule Expression in B Cells Acute Lymphoblastic Leukemia (B-ALLs): A Flow-Cytometric Marker for an Accurate Diagnostic Workup.

Background: B-lineage acute lymphoblastic leukemias (B-ALL) harboring the t(9;22)(q34;q11)/BCR::ABL1 rearrangement represent a category with previously dismal prognosis whose management and outcome dramatically changed thanks to the use of tyrosine kinase inhibitors (TKIs) usage and more recently full chemo-free approaches. The prompt identification of these cases represents an important clinical need.

Objectives: We sought to identify an optimized cytofluorimetric diagnostic panel to predict the presence of Philadelphia chromosome (Ph) in B-ALL cases by the introduction of CD146 in our multiparametric flow cytometry (MFC) panels.

Treatment free remission (TFR) after second-generation tyrosine kinase inhibitors (2G-TKIs) treatment in chronic myeloid leukemia (CML): from feasibility to safety.

Introduction: Chronic myeloid leukemia (CML) prevalence is currently increasing due to the great efficacy of tyrosine kinase inhibitor (TKI) therapy. Discontinuation of treatment in the long-term, owing to avoid off-target side effects or treatment-free remission (TFR), has become an additional treatment goal in CML patients who achieved a deep molecular response (DMR). Second-generation TKIs (2 G-TKIs) have a significantly higher rate of DMR than imatinib.
