Impact of Leukemia Stem Cells Phenotype Expression on Response to Induction Therapy in Acute Myeloid Leukemia Patients.
CONCLUSIONS: 1. LSCs were expressed in 63.41% of AML cases and were distributed among FAB subtypes without preference to any FAB subtype. 2. The expression of LSC phenotype was associated with poor response to induction therapy in AML patients. PMID: 31438833 [PubMed - as supplied by publisher]
Genetic mutations can predict favorable or unfavorable prognosis of AML patients. Allo stem cell transplantation can provide benefits for AML patients with bad genetic mutations. AbstractTo explore the characteristics and prognostic significance of genetic mutations in acute myeloid leukemia (AML), we screened the gene mutation profile of 171 previously untreated AML patients using a next ‐generation sequencing technique targeting 127 genes with potential prognostic significance. A total of 390 genetic alterations were identified in 149 patients with a frequency of 87.1%. Younger age and high sensitivity to induction che...
ong The first report of cancer stem cell (CSC) from Bruce et al. has demonstrated the relatively rare population of stem-like cells in acute myeloid leukemia (AML). The discovery of leukemic CSCs prompted further identification of CSCs in multiple types of solid tumor. Recently, extensive research has attempted to identity CSCs in multiple types of solid tumors in the brain, colon, head and neck, liver, and lung. Based on these studies, we hypothesize that the initiation and progression of most malignant tumors rely largely on the CSC population. Recent studies indicated that stem cell-related markers or signaling path...

Discussion: The present study evaluated the potential prognostic role of WBC count nadir and duration of aplasia, demonstrating that they are not associated with treatment outcomes in adult patients with AML treated with intensive chemotherapy. Therefore, a short duration of aplasia seems not linked to poor therapeutic efficacy in clearing bone marrow blasts. Our findings, although needing validation in larger and more homogeneous cohorts, may offer helpful clues in the management of aplasia of AML patients.Chemotherapy
Conclusions: The case expands the understanding of secondary CML and emphasizes the importance of oncological vigilance in patients with secondary CML after AML therapy. PMID: 32936052 [PubMed - as supplied by publisher]
The treatment option for children with intermediate-risk acute myeloid leukemia (IR-AML) in first complete remission is controversial. We retrospectively analyzed the outcomes of 80 children with IR-AML, and compared the effect of chemotherapy with haplo-HSCT as post-remission treatment. Compared with chemotherapy group, haplo-HSCT group had a significantly lower risk of relapse, especially in patients with minimal residual disease ≥10-3 after induction therapy.
AML is characterized by uncontrolled proliferation of clonal hematopoietic precursor cells. This interrupts normal hematopoiesis and may lead to bone marrow failure. It predominantly occurs in older adults, with the average age at diagnosis being 68 years (1). Intensive chemotherapy combined with hematopoietic stem cell (HSC) transplantation has considerably improved outcomes in younger adults. However about 80% of older adults still succumb to the disease or to the associated therapeutic toxicity (2).
ov A, Dietmann S, Cavo M, Catani L, Curti A, Vázquez J, Frezza C, Huntly BJ, Schwaller J, Méndez-Ferrer S Abstract Like normal hematopoietic stem cells, leukemic stem cells depend on their bone marrow (BM) microenvironment for survival, but the underlying mechanisms remain largely unknown. We have studied the contribution of nestin+ BM mesenchymal stem cells (BMSCs) to MLL-AF9-driven acute myeloid leukemia (AML) development and chemoresistance in vivo. Unlike bulk stroma, nestin+ BMSC numbers are not reduced in AML, but their function changes to support AML cells, at the expense of non-mutated h...
Acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) and treatment-related acute myeloid leukemia (tAML) after chemotherapy or radiation therapy for other neoplasms are associated with poor outcomes. CPX-351, a dual-drug liposomal encapsulation of daunorubicin and cytarabine, has been shown to improve outcomes in AML-MRC and tAML compared with standard 7+3 regimens. Here we report the cases of four consecutive patients with AML-MRC or tAML who received CPX-351 as outpatient induction therapy immediately followed by allogeneic hematopoietic stem cell transplantation (allo-HSCT). Two patients received allo-HS...
Conclusions: As the role and efficacy of autologous HDCT/ABSCT are not established in the analyzed entities, the indication for PBSC collection should be reanalyzed in regular intervals. Moreover, PBSC grafts from patients who have deceased, have insufficient grafts, or have already undergone an allogeneic TPL should be considered for disposal or (if applicable) for research use, to economize storage costs on a rational basis.Transfus Med Hemother
