Olfactory neuroblastoma (ONB), sinonasal undifferentiated carcinoma (SNUC), and sinonasal neuroendocrine carcinoma (SNEC) are rare malignancies arising from the sinonasal tract with limited therapeutic options. The expression of the somatostatin receptor 2 gene (), which is expressed in other neuroendocrine neoplasms and is therapeutically actionable, has been reported in these tumors. Here, we analyzed gene expression and its associations with genomic features, established biomarkers predicting of immune response, and the tumor immune microenvironment in a cohort of ONB, SNUC, and SNEC tumor samples (26, 13, and 8 samples, respectively) from a real-world database.

Patient recruitment is challenging for clinical trials. We introduce TrialGPT, an end-to-end framework for zero-shot patient-to-trial matching with large language models. TrialGPT comprises three modules: it first performs large-scale filtering to retrieve candidate trials (TrialGPT-Retrieval); then predicts criterion-level patient eligibility (TrialGPT-Matching); and finally generates trial-level scores (TrialGPT-Ranking).

Article Synopsis
  • Invasive fungal infections (IFIs) are a significant health issue for patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), and Isavuconazole (ISA) is a safe antifungal treatment option being studied in combination with sirolimus.
  • This retrospective analysis looked at 51 allo-HSCT patients treated with both ISA and sirolimus over about five years, focusing on the effectiveness, safety, and monitoring of drug levels.
  • Results showed that ISA was effective in treating IFIs, with a 68% response rate after 90 days, and no significant drug interaction toxicities were reported when both drugs were administered at therapeutic levels.

Background: Artificial intelligence is increasingly being applied to many workflows. Large language models (LLMs) are publicly accessible platforms trained to understand, interact with, and produce human-readable text; their ability to deliver relevant and reliable information is also of particular interest for the health care providers and the patients. Hematopoietic stem cell transplantation (HSCT) is a complex medical field requiring extensive knowledge, background, and training to practice successfully and can be challenging for the nonspecialist audience to comprehend.

Article Synopsis
  • Invasive fungal diseases (IFDs) are a significant cause of mortality in patients with hematological conditions like AML and MDS, particularly during chemotherapy and after stem cell transplants.
  • Mold-active antifungal prophylaxis (MAP) is the standard care, though breakthrough infections (b-IFDs) like invasive aspergillosis remain a pressing issue.
  • A study of 184 AML/MDS patients showed a 1.7% incidence of b-IFDs while undergoing high-dose chemotherapy with posaconazole, highlighting ongoing challenges in diagnosis and treatment adaptations in a rapidly changing medical landscape.

Cytomegalovirus (CMV) reactivations are strong stimulators of immune-reconstitution (IR) in hematopoietic stem cell transplantation (HSCT) recipients. Herein, we analyzed 317 CMV-seropositive consecutive patients (n = 109 letermovir, LTV; n = 208 no-LTV), undergoing HSCT with post-transplant cyclophosphamide (PTCy) and calcineurin inhibitor- (CNI) free graft-versus-host-disease (GvHD) prophylaxis. At day+90, median CD19/mm was higher in LTV-cohort: 5.

Article Synopsis
  • Allogeneic stem cell transplantation is a strong treatment for Myelofibrosis (MF), and splenic irradiation can help shrink the spleen and improve symptoms.
  • A study looked at 14 MF patients who had this treatment from June 2016 to March 2021, and most had successful results, with many seeing a decrease in spleen size after three months.
  • After about 25 months, some patients were no longer needing transfusions, but a few had relapses or sadly passed away, showing that more research is needed to confirm these results.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) in SARS-CoV-2 positive candidates is usually delayed until the clinical resolution of the infection's symptoms and a negative nasopharyngeal molecular test. However, prolonged SARS-CoV-2 positivity has been frequently observed in haematological malignancies, thus representing a challenge for the timing of transplant procedures. Here, we report on the case of a 34-year-old patient with recent pauci-symptomatic COVID-19 undergoing transplant for high-risk acute B-lymphoblastic leukemia before achieving viral clearance.

Introduction: Acute kidney injury (AKI) is a frequent early complication post hematopoietic stem cell transplant (HSCT), associated with high morbidity and mortality. Cord blood transplant (CBT) recipients are potentially exposed to more nephrotoxic insults, compared to patients undergoing HSCT from other donor sources. We aimed to identify risk factors for AKI in patients undergoing CBT.

Several strategies have been explored with the attempt of improving the safety and feasibility of umbilical cord blood transplantation (UCBT) in adults. The aim of this retrospective analysis was to examine the safety and efficacy of intrabone transplantation of a single unwashed cord blood unit in an antithymocyte globulin-free, sirolimus-based graft-versus-host disease prophylaxis platform. We collected data for all consecutive UCBTs infused intrabone (IB) and unwashed at San Raffaele Hospital in Milan between 2012 and 2021.

Human herpesvirus 6 (HHV-6) can reactivate after allogeneic hematopoietic stem cell transplant (allo-HSCT) and may lead to severe symptoms. HHV-6-specific immune responses after HSCT are largely unexplored. We conducted a prospective observational study on 208 consecutive adult patients who received allo-HSCT to investigate HHV-6 reactivations and specific immune responses.

Philadelphia (Ph)-like acute lymphoblastic leukemia (ALL) constitutes a heterogeneous subset of ALL with a uniformly unfavorable prognosis. The identification of mutations amenable to treatment with tyrosine kinase-inhibitors (TKIs) represents a promising field of investigation. We report the case of a young patient affected by relapsed/refractory Ph-like ALL treated with chimeric antigen receptor T (CAR-T) cells after successful bridging with compassionate-use ponatinib and low-dose prednisone.

Article Synopsis
  • A 59-year-old woman had serious problems with her organs after getting a special stem cell transplant, and later she showed signs of brain issues.
  • Doctors figured out she had a weird condition called posterior reversible encephalopathy syndrome (PRES) after doing tests and scans.
  • They stopped some of her medication, managed her blood pressure, gave her strong medicine, and after two weeks, her brain problems improved and tests showed she was getting better.

Fluoroquinolone prophylaxis's (FQ-P) usefulness in patients with neutropenia is controversial. In recent decades, Italian epidemiological data has shown worrisome rates of FQ resistance. A single-center cohort study on 136 autologous stem cell transplantations (ASCTs) and 223 allogeneic hematopoietic stem cell transplantations (allo-HSCTs) was performed from January 2018 to December 2020.

Systemic sclerosis (SSc) is a systemic disease characterized by autoimmune responses, vasculopathy and tissue fibrosis. The pathogenic mechanisms involve a wide range of cells and soluble factors. The complexity of interactions leads to heterogeneous clinical features in terms of the extent, severity, and rate of progression of skin fibrosis and internal organ involvement.

After allogeneic hematopoietic stem cell transplantation (HSCT), the emergence of circulating cytomegalovirus (CMV)- specific T cells correlates with protection from CMV reactivation, an important risk factor for non-relapse mortality. However, functional assays measuring CMV-specific cells are time-consuming and often inaccurate at early time-points. We report the results of a prospective single-center, non-interventional study that identified the enumeration of Dextramerpositive CMV-specific lymphocytes as a reliable and early predictor of viral reactivation.

Post-transplant cyclophosphamide (PTCy) has emerged as a promising graft-versus-host disease (GvHD) prophylaxis in allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, no studies have reported the efficacy of a GvHD prophylaxis based on PTCy with sirolimus (Sir-PTCy) in patients with acute myeloid leukemia (AML). In this retrospective study, we analyze the use of sirolimus in combination with PTCy, with or without mycophenolate mofetil (MMF), on 242 consecutive adult patients with AML undergoing a myeloablative first allo-HSCT from different donor types, in three European centers between January 2017 and December 2020.

Correlation between risk of graft-versus-host disease (GvHD) and CD3 counts within the peripheral blood stem cell graft has recently been reported in the setting of post-transplant cyclophosphamide (PT-Cy). We aimed to investigate the benefit of the addition of a single dose of anti-T lymphocyte globulin (ATLG 5 mg/kg) to PT-Cy in this setting. Starting in 2019, all patients receiving PBSC transplant containing CD3 counts above 300 × 10/kg (study group) received a post-transplant dose of ATLG in addition to standard PT-Cy.
