Elevated serum direct bilirubin is predictive of a poor prognosis for primary myelodysplastic syndrome. (PubMed, BMC Cancer)

An elevated DBIL level was identified as an independent adverse prognostic factor for MDS patients. An individualized prediction model was established and validated to improve prediction of OS and LFS.

DNMT3A, TET2, and ASXL1 (DTA) Mutations Are Associated with Thrombosis and Bleeding in Patients with Myeloproliferative Neoplasms (ASH 2024)

DTA mutations detected with a clinically used NGS panel in patients with MPN are associated with increased risk of bleeding complications, as well as increased thrombotic risk in a subgroup of patients. These findings support the incorporation of molecular panel analyses in thrombosis and bleeding risk assessment in MPN, and merit further investigation.

Clonal Evolution of TP53 Configurations with Treatment Predict Prognosis in Myeloid Neoplasms (ASH 2024)

Serial NGS-based studies in patients with TP53MT inform important clues to prognosis. While being a dominant or persistent TP53MT clone either at the same configuration or up-trending clonal burden post treatment equates to poor prognosis, it is crucial to study further those who display better clinical outcomes with standard-of-care treatment. Such information will be invaluable for making treatment decisions in this grave prognostic disease otherwise.

These data indicate that classical mutations of JAK2, MPL, and CALR may not be completely mutually exclusive with atypical variants of JAK2, MPL, and CALR. In this study, 30 different atypical variants of JAK2, MPL, and CALR were identified, JAK2 G127D being the most common (42%, 23/55). Interestingly, JAK2 G127D only co-occurred with JAK2V617F mutation. The incidence of atypical variants of JAK2 in Ph-negative MPNs was much higher than that of the atypical variants of MPL and CALR.

TN-MF is invariably associated with significantly decreased survival and more aggressive clinical behavior with higher rates of leukemic transformation and shorter duration of response to ruxolitinib. Mutations impacting RNA splicing, epigenetic modification and signaling (SRSF2, SETBP1, IDH2, CBL, and GNAS) are more common in TN-MF, which likely drive its aggressive course and may account for suboptimal responses to JAK inhibition.

Therapeutic Targeting of TIM-4-L With Engineered T Cells for Acute Myeloid Leukemia. (PubMed, Clin Cancer Res)

These results highlight TIM-4-L as a highly prevalent target on AML across a range of genetic classifications and novel target for T cell-based therapy in AML. Further investigations into the role of TIM-4-L in AML pathogenesis and its potential as an anti-leukemic target for clinical development are warranted.

Chronic myelomonocytic leukemia: 2024 update on diagnosis, risk stratification and management. (PubMed, Am J Hematol)

Drug therapy is currently not disease-modifying and includes hydroxyurea and hypomethylating agents; a recent phase-3 study (DACOTA) comparing hydroxyurea and decitabine, in high-risk MP-CMML, showed similar overall survival at 23.1 versus 18.4 months, respectively, despite response rates being higher for decitabine (56% vs. 31%). These include systemic inflammatory autoimmune diseases, leukemia cutis and lysozyme-induced nephropathy; the latter requires close monitoring of renal function during leukocytosis and is a potential indication for cytoreductive therapy.

Sex and race-dependent variations in the mutational landscape of clonal hematopoiesis (AACR 2024)

Our analysis provides insights into the complex interplay of sex and racial factors in shaping CHIP mutation frequencies. As CHIP continues to gain recognition as a critical precursor to malignancies, understanding these variations contributes to refining our understanding of its underlying mechanisms and clinical implications.

A comprehensive genomic profiling of myeloid malignancies demonstrates mutational spectrum of DNA variants, FLT3-ITDs, and gene fusions (AACR 2024)

The Oncomine Myeloid Assay is a fast, robust, and reproducible solution for comprehensive genomic profiling of myeloid malignancies. We describe the mutational spectrum of DNA variants and RNA fusions in a range of clinical research samples. (For research use only.

Molecular and clinical analyses of PHF6 mutant myeloid neoplasia provide their pathogenesis and therapeutic targeting. (PubMed, Nat Commun)

Finally, we demonstrate a negative prognostic role of PHF6MT, especially in association with RUNX1. The negative effects on survival are additive as PHF6MT cases with RUNX1 mutations have worse outcomes when compared to cases carrying single mutation or wild-type.

Analysis of CHIP-Related Mutation and Risk of Cardio-Cerebrovasculars Events in Patients with Myeloproliferative Neoplasms (PubMed, Zhongguo Shi Yan Xue Ye Xue Za Zhi)

There is a higher mutation rate of CHIP-related genes in MPN patients, especially those over 60 years old. Older age, thrombosis history, CHIP-related mutations and IL-1β elevated levels are independent risk factors for CCEs in MPN. DNMT3A and ASXL1 mutations are independent risk factors for CCEs in PV patients. CHIP-related gene mutations and inflammatory cytokine IL-1 β elevated levels may be the novel risk factors for CCEs in MPN.
