Although the majority of congenital neutropenia patients respond to daily granulocyte colony stimulating factor, approximately 15 % do not respond to this cytokine at doses up to 50 μg/kg/day and approximately 15 % of patients will develop myelodysplasia or acute myeloid leukemia.
Although myeloablative HLA haploidentical hematopoietic stem cell transplantation (haplo-HSCT) following pretransplant anti-thymocyte globulin (ATG) and granulocyte colony-stimulating factor (G-CSF) stimulated grafts (ATG+G-CSF) has been confirmed as an alternative to HSCT from HLA-matched sibling donors (MSD), the effect of haplo-HSCT on postremission treatment of patients with acute myeloid leukemia (AML) with intermediate risk (int-risk AML) who achieved first complete remission (CR1) has not been defined.
Median 2% HSCs from blood and 15% HSCs from filgrastim-mobilized grafts were killed with 50 mg/L ATG, compared to 30% LSCs from the blood of AML patients (p = 0.001 and 0.022, respectively).
The FLAG (fludarabine, high-dose Ara-C, supported with granulocyte colony-stimulating factor) regimen has been tested for use in AML patients by other investigators.
A higher of MDS/AML was observed in patients with NHL risk among those who received G-CSF that was specific to the use of filgrastim (≥10 doses), but not pegfilgrastim.
CONCLUSIONS Our results showed that unmanipulated haploidentical transplantation with G-CSF primed PBSC alone as a graft source could be an acceptable alternative post-remission treatment for high-risk or intermediate-risk AML patients in CR1 lacking a matched donor.
The granulocyte colony stimulating factor (G-CSF) receptor is expressed on the cell surface of some blood cancers such as acute myeloid leukemia (AML).
The use of granulocyte colony-stimulating factor primed halo-identical MST appears to be a biologically active therapy in patients with refractory acute myeloid leukemia (AML), especially in patients received less than four previous chemotherapy lines, fludarabine-free previous chemotherapy, response naïve and young age patients.
Clinical efficacy of decitabine in combination with standard-dose cytarabine, aclarubicin hydrochloride, and granulocyte colony-stimulating factor in the treatment of young patients with newly diagnosed acute myeloid leukemia.
Proteomic Profiling of Signaling Networks Modulated by G-CSF/Plerixafor/Busulfan-Fludarabine Conditioning in Acute Myeloid Leukemia Patients in Remission or with Active Disease prior to Allogeneic Stem Cell Transplantation.
Treatment with chemotherapy plus G-CSF appears to provide better survival and treatment responses compared with chemotherapy alone, particularly for patients with previously untreated AML.
Decitabine in combination with G-CSF, low-dose cytarabine and aclarubicin is as effective as standard dose chemotherapy in the induction treatment for patients aged from 55 to 69 years old with newly diagnosed acute myeloid leukemia.
This retrospective study tested the feasibility of decitabine (DAC) plus intermediate-dose cytarabine (ID-AraC) followed by HLA-mismatched granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral donor blood stem cells (GPBSCs) infusion as consolidation treatment for older patients with acute myeloid leukemia (AML) in first complete remission (CR).
The low-dose cytarabine, aclarubicin and granulocyte-colony stimulating factor (G-CSF) (CAG) priming regimen is an effective treatment for patients with relapsed or refractory acute myeloid leukemia (AML) and advanced myelodysplastic syndrome (MDS).
These results elucidate that standard chemotherapy followed by G-CSF priming new double induction chemotherapy is an effective method for AML patients to improve CR rate and reduce adverse effects.
To explore the efficacy, and safety of the intensive conditioning regimen consisting of cladribine, cytarabine (Ara-C), and granulocyte colony-stimulating factor (G-CSF) plus modified busulfan (Bu) combined with cytoxan (Cy) (BuCy), prior to allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with refractory, or relapsed acute myeloid leukemia (R/R AML).Thirty-Six R/R AML patients scheduled to receive allo-HSCT were consecutively, enrolled in this prospective study, and treated using intensive conditioning regimen consisting of CLAG plus modified BuCy.
Outcomes of fludarabine, high dose cytarabine and granulocyte-colony stimulating factor (FLAG) as re-induction for residual acute myeloid leukemia on day 14 bone marrow.
Trials demonstrating improved outcomes with high-dose cytarabine, addition of cladribine, or escalated anthracycline doses prompted a phase 1/2 study (NCT02044796) of G-CSF, cladribine, high-dose cytarabine, and dose-escalated mitoxantrone (GCLAM) in adults with newly-diagnosed AML or other high-grade myeloid neoplasms.
Recently, our institution adopted the FLAG regimen (fludarabine, cytarabine, and granulocyte colony-stimulating factor) based on data reporting similar outcomes to CLO in elderly patients with AML unable to tolerate anthracycline-based induction.
Our findings suggest that miR-146a may be a novel biomarker for evaluating the clinical prognosis and treatment effects of a G-CSF priming protocol in elderly patients with AML.
It is evident that G-CSF reversed immunosuppression of the AML microenvironment by reducing SDF-1α in bone marrow and elevating Tregs in the peripheral blood in <i>in vivo</i> studies.
We conducted a prospective study of 23 elderly patients (median age, 68 years; range, 60 to 87 years) with newly diagnosed AML to evaluate the efficacy and toxicity of decitabine plus granulocyte colony-stimulating factor priming, low-dose aclarubicin, and cytarabine (DCAG) chemotherapy combined with HLA-mismatched stem cell microtransplantation (SC-MST) without graft-versus-host disease (GVHD) prophylaxis.
