Article Synopsis
  • Treatment outcomes for acute promyelocytic leukemia (APL) have significantly improved through targeted therapies like ATRA and arsenic trioxide, as confirmed by a study analyzing 1,438 newly diagnosed patients from 1999 to 2022.
  • Among those treated, patients receiving the ATRA-ATO regimen demonstrated a higher 7-year overall survival rate (91%) compared to those on AIDA-like chemotherapy (81%), along with better event-free survival and lower relapse rates.
  • The study highlights the ongoing issue of early death, particularly in older patients and those with high Sanz risk scores, suggesting a need for further examination and targeted interventions in these vulnerable groups.

Steroid-refractory acute and chronic graft-versus-host disease (SR-a/cGvHD) represents a potential life-threatening complication following allogeneic stem-cell transplantation (allo-SCT). The JAK1/2-inhibitor ruxolitinib and the extracorporeal photopheresis (ECP) have been shown to significantly improve the overall response rate (ORR) in this setting. However, about 30-40 % of high-risk patients do not respond to monotherapy and/or experience side effects.

Desmoplastic small round blue cell tumor (DSRCT) is a highly aggressive fatal sarcoma without evidence-based therapeutic guidelines. We present here seven patients with DSRCT including immunohistochemistry combined with fluorescence in situ hybridization (FISH), next generation sequencing (NGS,  = 6) as well as OncoScan array ( = 3) analyses and show consecutive therapeutic approaches. All seven DSRCT patients presented with an extended abdominal mass; median age at diagnosis was 24.

In a randomized phase II trial (AMLSG 14-09, NCT00867672) of elderly, newly diagnosed AML patients, ATRA combined with decitabine (DEC) significantly improved the overall response rate (ORR) and survival also in patients with adverse-risk genetics, without adding toxicity. We performed a post hoc analysis to determine the predictive impact of TP53 status. Despite a nominally higher ORR, the clinically meaningful survival benefit when adding ATRA to DEC was diminished, but not completely negated, in TP53-mutated patients.

Measurable residual disease (MRD) monitoring in acute myeloid leukemia (AML) with an FLT3 internal tandem duplication (FLT3-ITDpos) has been hampered by the broad heterogeneity of ITD mutations. Using our recently developed FLT3-ITD paired-end next-generation sequencing (NGS)-based MRD assay (limit of detection 10-4 to 10-5), we evaluated the prognostic impact of MRD at different time points in 157 patients with FLT3-ITDpos AML who were enrolled in the German-Austrian Acute Myeloid Leukemia Study Group 16-10 trial and who were treated with a combination of intensive chemotherapy and midostaurin, followed by midostaurin maintenance. MRD negativity (MRDneg) after 2 cycles of chemotherapy (Cy2), which was observed in 111 of 142 (78%) patients, was predictive of superior 4-year rates of cumulative incidence of relapse (CIR) (4y-CIR; 26% vs 46%; P = .

Article Synopsis
  • Acute myeloid leukemia (AML) often involves deletions of chromosome 7, which are linked to poor patient outcomes, but the full impact of other genetic changes related to this is not well understood.
  • Researchers analyzed genetic alterations in 519 AML patients, using whole-exome sequencing and a specialized gene panel, finding that mutations in TP53, which occurred in 33% of cases, were among the most common.
  • The study identified specific genes, like TP53 and PTPN11, that have a significant negative effect on overall and relapse-free survival, highlighting the complex relationship between chromosome 7 abnormalities and patient prognosis in AML.

Article Synopsis
  • The European LeukemiaNet (ELN) previously created genetic risk classifications using data from younger adults who underwent intensive chemotherapy.
  • New research has emerged analyzing patients who receive less-intensive therapies, highlighting the need for tailored classifications.
  • This has led to a proposal for a new ELN genetic risk classification specifically designed for patients undergoing these alternative treatment options.

Article Synopsis
  • The European LeukemiaNet (ELN) classification systems for acute myeloid leukemia (AML) are based on chemotherapy responses and may not effectively predict outcomes for older patients receiving venetoclax-azacitidine.
  • A pooled analysis from the phase 3 VIALE-A trial revealed that most patients were classified with adverse-risk AML, yet these classifications did not correlate well with survival outcomes for those treated with venetoclax-azacitidine.
  • New molecular signatures based on mutations in TP53, FLT3-ITD, NRAS, and KRAS identified three distinct patient benefit groups, each with significantly different median overall survival times.

Balanced rearrangements involving the KMT2A gene (KMT2Ar) are recurrent genetic abnormalities in acute myeloid leukemia (AML), but there is lack of consensus regarding the prognostic impact of different fusion partners. Moreover, prognostic implications of gene mutations co-occurring with KMT2Ar are not established. From the HARMONY AML database 205 KMT2Ar adult patients were selected, 185 of whom had mutational information by a panel-based next-generation sequencing analysis.

Multiple myeloma (MM) is a plasma cell malignancy of the bone marrow. Despite therapeutic advances, MM remains incurable, and better risk stratification as well as new therapies are therefore highly needed. The proteome of MM has not been systematically assessed before and holds the potential to uncover insight into disease biology and improved prognostication in addition to genetic and transcriptomic studies.

In the phase 3 QUAZAR AML-001 trial (NCT01757535) of patients with acute myeloid leukaemia (AML) in remission following intensive chemotherapy (IC) and ineligible for haematopoietic stem cell transplant (HSCT), oral azacitidine (Oral-AZA) maintenance significantly prolonged overall survival (OS) versus placebo. The impact of subsequent treatment following maintenance has not been evaluated. In this post hoc analysis, OS was estimated for patients who received subsequent AML therapy, and by regimen received (IC or lower-intensity therapy).

Most patients with acute myeloid leukemia (AML) develop refractory/relapsed (R/R) disease even in the presence of novel and targeted therapies. Given the biological complexity of the disease and differences in frontline treatments, there are therapies approved for only subgroups of R/R AML, and enrollment in clinical trials should be first priority. Allogeneic hematopoietic cell transplantation (HCT) is the only potentially curative strategy for most patients.
