The Clinical Influence of Complete Remission With Incomplete Count Recovery (CRi) on Single-Unit Unrelated Cord Blood Transplantation in Patients With Acute Leukemia.

Abstract
Recent evidence has indicated that measurable residual disease (MRD) markedly affects the prognosis of patients with acute leukemia post-transplantation. However, the prognostic relevance of complete remission with incomplete count recovery (CRi) before transplantation has not been extensively explored. In this single-center, longitudinal study, we assessed the outcomes of 466 MRD-negative acute leukemia patients who underwent single-unit unrelated cord blood transplantation (sUCBT), including 117 patients with CRi. We observed that acute myeloid leukemia (AML) patients with CRi had a significantly lower cumulative incidence of both neutrophil (90.8% versus 96.5%) and platelet engraftment (67.2% versus 85.3%) and experienced increased transplant-related mortality (TRM) (100-day TRM: 14.2% versus 5.3%; 1-year TRM: 20.6% versus 11.3%; P = .024 and .063, respectively), mainly due to infection-related deaths, compared to those in complete remission (CR). Multivariate analysis revealed that CRi was an independent adverse predictor of both neutrophil and platelet engraftment and increased 100-day TRM in AML patients. However, CRi status did not affect relapse or reduce 5-year overall survival (OS), leukemia-free survival (LFS), or GVHD-free relapse-free survival (GRFS) in the AML cohort. Conversely, for patients with acute lymphoblastic leukemia (ALL), CRi did not impact engraftment, TRM, relapse or survival after sUCBT. Our findings underscore that CRi status before sUCBT portends poorer engraftment outcomes and a greater TRM in AML patients, although it does not significantly affect the prognosis of ALL patients.

Lack of RBC transfusion independence by Day 30 following allogeneic hematopoietic stem cell transplant strongly predicts inferior survival and high non-relapse mortality in acute myeloid leukemia patients. Transfusion 2024; 64:255-280. [PMID: 38225215 DOI: 10.1111/trf.17714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2023] [Revised: 11/29/2023] [Accepted: 12/15/2023] [Indexed: 01/17/2024]
Abstract
BACKGROUND Studies have suggested that acute myeloid leukemia (AML) patients with incomplete hematologic recovery undergoing allogeneic stem cell transplantation (allo-HSCT) had inferior overall survival (OS). STUDY DESIGN AND METHODS This single-center, retrospective study of AML patients evaluated the relationship between red blood cell (RBC) and platelet (PLT) transfusion requirements during the first 30 days and long-term outcomes after allo-HSCT through multivariate analyses. RESULTS A total of 692 AML patients received peripheral blood stem cells (89.2%), marrow (5.6%), or umbilical cord (5.2%) from matched related (37.4%), unrelated (49.1%), or haploidentical (8.2%) donors in 2011-2017. Transfusion requirements during the first 30 days for RBC (89.5% transfused, median 3, range 1-18 units) or PLT (98.2% transfused, median 6, range 1-144 units) were variable. By Day 30, 56.7% (95% confidence interval [CI]: 52.8-60.3%) and 86.1% (95% CI: 83.2-88.5%) had achieved RBC and PLT transfusion independence, respectively. Median follow-up among survivors (n = 307) was 7.1 years (range: 2.7-11.8). Lack of RBC transfusion independence by Day 30 was strongly and independently associated with worse 5-year OS (39.2% vs. 59.6%, adjusted hazard ratio [HR] 1.83, 95% CI: 1.49-2.25), leukemia-free survival (35.8% vs. 55.5%, HR = 1.75, 95% CI: 1.43-2.14), and NRM (29.7% vs. 13.7%, HR = 2.05, 95% CI: 1.45-2.89) (p < .001). There was no difference in relapse rates among patients who achieved or did not achieve RBC (p = .34) or PLT (p = .64) transfusion independence. CONCLUSION Prolonged RBC dependence predicted worse survival and NRM rates, but not increased relapse. Posttransplant surveillance of such patients should be adjusted with more attention to non-relapse complications.

A retrospective comparison of salvage intensive chemotherapy versus venetoclax-combined regimen in patients with relapsed/refractory acute myeloid leukemia (AML). Ther Adv Hematol 2022; 13:20406207221081637. [PMID: 35340720 PMCID: PMC8949776 DOI: 10.1177/20406207221081637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Accepted: 01/31/2022] [Indexed: 11/16/2022] Open
Abstract
Background: Evidence that a venetoclax (VEN)-combined regimen is effective in relapsed/refractory acute myeloid leukemia (R/R AML) is emerging. However, it is unknown how VEN-combined low intensity treatment compares to intensive chemotherapy (IC) in medically fit patients with R/R AML. Methods: We compared AML patients who received IC (n = 89) to those who received a VEN in combination with hypomethylating agents or low dose cytarabine (VEN combination) (n = 54) as their first- or second-line salvage after failing anthracycline-containing intensive chemotherapy. Results: The median age was 49 years, and significantly more patients in the VEN combination group were in their second salvage and had received prior stem cell transplantation (SCT). Overall response rates including CR, CRi, and MLFS were comparable (44.0% for IC vs. 59.3% for VEN combination, p = 0.081), but VEN combination group compared to IC group tended to show lower treatment related mortality. The rate of bridging to SCT was the same (68.5%), but the percentage of SCT at blast clearance was significantly higher in the VEN-combined group (62.3% vs. 86.5%, p = 0.010). After median follow-up periods of 22.5 (IC) and 11.3 months (VEN combination), the median overall survival was 8.9 (95% CI, 5.4-12.4) and 12.4 months (95% CI, 9.5-15.2) (p = 0.724), respectively. Conclusion: VEN combination provides a comparable anti-leukemic response and survival to salvage IC, and provide a bridge to SCT with better disease control in medically-fit patients with R/R AML.

Abstract
Objective: The prognosis of patients with acute myeloid leukemia (AML) is affected by factors that are both patient- and disease-specific. The aim of this study is to evaluate the impact of early versus late platelet and neutrophil recovery after induction chemotherapy on survival outcomes of AML patients. Materials and Methods: A total of 181 patients with AML who were treated in our tertiary center between 2001 and 2018 were evaluated. Neutrophil and platelet recovery times were accepted as the periods from the beginning of induction chemotherapy to a neutrophil count of ≥0.5x109/L and a platelet count of ≥20x109/L 3 days in a row, respectively. The median time to platelet recovery was 25 days (range=12-52) for all patients. Therefore, platelet recovery in the first 25 days was defined as early platelet recovery (EPR) and at ≥26 days it was defined as late platelet recovery (LPR). The median time to neutrophil recovery was 28 days (range=13-51) for all patients. Therefore, neutrophil recovery in the first 28 days was defined as early neutrophil recovery, and at ≥29 days it was defined as late neutrophil recovery. Results: The 5-year overall survival (OS) rates for patients who had EPR and LPR after induction chemotherapy were 62% and 23%, respectively (p<0.001). The 5-year disease-free survival (DFS) rates for patients who had EPR and LPR after induction chemotherapy were 57% and 15%, respectively (p<0.001). Conclusion: Short bone marrow recovery time may indicate better healthy hematopoiesis and marrow capacity associated with longer OS and DFS.
