Gemtuzumab ozogamicin in first-line treatment of CBF-AML: insights from a retrospective multi-center analysis.

The addition of gemtuzumab ozogamicin (GO) to intensive chemotherapy (IC) has become a mainstay in treating patients with core binding factor acute myeloid leukemia (CBF-AML). However, evidence for the efficacy of GO in this particular subgroup is primarily based on meta-analytic data from different trials conducted more than a decade ago. In this registry-based study, we evaluated the impact of adding GO to IC in 265 CBF-AML patients from the SAL, AMLCG, and CELL cooperative study groups.

High-Dose Melphalan Followed by Busulfan and Fludarabine Conditioning Prior to Allogeneic Stem Cell Transplantation in Elderly Patients with Active Acute Myeloid Leukemia-A Retrospective Single-Center Study.

In patients with relapsed or refractory (r/r) acute myeloid leukemia (AML), long-term survival in most cases can only be achieved with allogeneic hematopoietic stem cell transplantation. The introduction of sequential conditioning regimens has contributed to the steadily improving prognosis of r/r AML patients. As most studies mainly included younger patients, feasibility of sequential conditioning in elderly or comorbid patients remains subject of debate.

Common hereditary variants of the APOE gene and posttransplant outcome in acute myeloid leukemia.

Apolipoprotein E (APOE) has multiple functions in metabolism and immunoregulation. Its common germ line variants APOE2, APOE3, and APOE4 give rise to 3 functionally distinct gene products. Previous studies reported yin-yang roles of APOE2 and APOE4 in immunological processes, but their effects in hematopoietic stem cell transplantation (HSCT) have never been studied.

Early blast clearance during sequential conditioning prior to allogeneic stem cell transplantation in patients with acute myeloid leukaemia.

For patients with relapsed or refractory AML, sequential conditioning prior to allogeneic stem cell transplantation (alloSCT) is an established and potentially curative treatment option. Early response to treatment during conditioning indicates chemotherapy-responsive disease and may have prognostic value. We retrospectively evaluated blast clearance on day 5 after melphalan, administered 11 days prior to alloSCT as part of a sequential conditioning in 176 patients with active AML.

Comparable outcomes for TBI-based versus treosulfan based conditioning prior to allogeneic hematopoietic stem cell transplantation in AML and MDS patients.

Allogeneic hematopoietic stem cell transplantation (allo-HCT) is a standard treatment for patients with AML and MDS. The combination of fractionated total body irradiation(8GyTBI/Flu) with fludarabine is an established conditioning regimen, but fludarabine/treosulfan(Flu/Treo) constitutes an alternative in older/comorbid patients. We conducted a retrospective analysis of 215 AML(in CR) and 96 MDS patients undergoing their first allo-HCT between 2011 and 2022, identifying 53 matched Flu/Treo and 8GyTBI/Flu patients through propensity score matching.

Combinatorial effects of doxorubicin and retargeted tissue factor by intratumoral entrapment of doxorubicin and proapoptotic increase of tumor vascular infarction.

Truncated tissue factor (tTF), retargeted to tumor vasculature by GNGRAHA peptide (tTF-NGR), and doxorubicin have therapeutic activity against a variety of tumors. We report on combination experiments of both drugs using different schedules. We have tested fluorescence- and HPLC-based intratumoral pharmacokinetics of doxorubicin, flow cytometry for cellular phosphatidylserine (PS) expression, and tumor xenograft studies for showing in vivo apoptosis, proliferation decrease, and tumor shrinkage upon combination therapy with doxorubicin and induced tumor vascular infarction.
